　　CCTV News:According to the WeChat official account of the Ministry of Transport, recently, the Ministry of Transport issued the "Notice on Maintaining Fair Competition Market Order and Accelerating the Promotion of Online Car-hailing Compliance" (hereinafter referred to as the "Notice") to further maintain fair competition market order, accelerate the promotion of online car-hailing Compliance process, and promote the healthy and sustainable development of the online car-hailing industry.

　　The "Notice" pointed out that recently, some online car-hailing platform companies have recruited or induced unlicensed drivers and vehicles to "bring cars to join" and carried out illegal operations, which seriously disrupted the market order of fair competition and affected the safety and stability of the industry. Local transportation authorities should further improve their political position, fully understand the importance of online car-hailing compliance to maintaining a fair competitive market environment, and tighten the compliance of enterprises with the law.

　　The "Notice" requires that local transportation authorities should urge online car-hailing platform companies to operate in accordance with laws and regulations, and speed up the process of online car-hailing compliance. From now on, no new access to non-compliant vehicles and drivers, and speed up the removal of non-compliant drivers and vehicles. It is necessary to strengthen supervision and law enforcement, strictly regulate law enforcement behavior, and comprehensively use various means such as online and offline to increase the crackdown on illegal operation of online car-hailing, and continue to maintain a high-pressure situation. Online car-hailing platform companies that are still new access to non-compliant vehicles and drivers shall be investigated and dealt with in accordance with laws and regulations, and the relevant situation shall be reported to the Ministry of Transport. At the same time, it is necessary to formulate a work plan for online car-hailing compliance, clarify goals, refine measures, and effectively promote compliance work, and adhere to both regulatory norms and promotion of development, optimize the approval process, strengthen services, and resolutely break the "glass door" and "revolving door" of license processing, so as to facilitate the licensing of online car-hailing platform companies, vehicles and drivers that meet the conditions for entry.

　　The "Notice" emphasizes that local transportation authorities should urge enterprises to implement their main responsibilities, strengthen their awareness of fair competition, and guide the formation of a market environment that advocates, protects, and promotes fair competition. It is necessary to work with relevant departments to accelerate the establishment of an all-round, multi-level, and three-dimensional supervision system, and strengthen the supervision of online car-hailing platform companies in the whole chain and all fields before and after the event, so as to improve the supervision efficiency. It is necessary to cooperate with relevant departments to increase the intensity of double random inspection work, and strictly investigate and punish low-price dumping, big data killing, and inducing fraud and other violations of laws and regulations in accordance with the law. Promote the formation of a unified, open, competitive and orderly market system, and effectively maintain the market order of fair competition.

　　The "Notice" makes it clear that local transportation authorities should actively work with relevant departments to guide and urge online car-hailing platform companies to comply with the law, scientifically formulate platform order dispatch rules, standardize pricing behavior, improve the benefit distribution mechanism, reduce the excessive proportion, ensure that drivers receive reasonable labor remuneration and rest time, and give full play to the role of 12328 transportation service supervision telephone to deal with complaints from drivers and passengers about the operation behavior of the platform in a timely manner. At the same time, it is necessary to strengthen the dynamic monitoring of market operation, timely investigation and resolution of various contradictions and disputes and risk hazards, ensure the stability of the industry, and urge online car-hailing platform enterprises to strengthen the safety education of online car-hailing drivers, and improve the safety level of industry operations.

　　It is reported that from September 2021, the Ministry of Transport will announce the compliance rate of online car-hailing in 36 central cities every month. For cities where eligible vehicles and drivers fail to comply due to problems such as delays in permit processing, the Ministry of Transport will make the list of cities public to the public.

Recently, from the School of Optoelectronics, Zhejiang University　Hao Xiang　The team of researchers is "Spectral Imaging with Deep Learning"The topic is　Lighting: Science & Applications　Published a review paper, sorted out the spectral imaging technology based on deep learning, explained the principle and research summary of its various technical routes, and organized the current spectral imaging dataset, outlining the possible future trends and challenges.

First, spectral images

The image we usually see in the display screen is an RGB three-color image, which has three channels of red, green and blue, that is, the color of each pixel is formed by superimposing the three colors of red, green and blue. If the three-color image is expanded to ten colors, hundred colors, and thousand colors, then our control and rendering of the image color will be extremely fine. An image with so many bands is a spectral image (term explanation >): it has more than three bands, which can be thirty or even hundreds.

Figure 1 Schematic diagram of a spectral image composed of 9 bands

The spectral information of a substance can fully reflect its internal physical structure and chemical composition. When there are enough wavelength bands in the image, each part is a spectral curve – reflecting the structural composition of the place. Therefore, the spectral image not only reflects the spatial characteristics of the imaging target, but also contains its structure and composition characteristics. Therefore, in addition to fine image rendering, the key application of spectral images is material composition analysis, which is widely used in remote sensing, medical detection, food detection and other fields.

Second, spectral imaging

Spectral imaging is a combination of imaging technology and spectral detection technology, and the main technical goal is to obtain spectral images. Traditional spectral imaging technology is scanning(Including point scanning, line scanning, band scanning)By constantly moving the spectrometer to obtain the spectrum of each point, a two-dimensional image is finally obtained. This scanning spectral imaging system is bulky and slow, which has been criticized.

Figure 2 Scanning spectral imaging (from left to right, point scan, first scan, and band scan)

With the development of computational optics, computational spectral imaging has become a new spectral imaging method. The method uses some coding to make the hidden spectral information enter the detector in a certain way, and finally uses the optimization algorithm to reconstruct the spectral image. The traditional computational spectral imaging method is iterative. Although it has effectively reduced the size of the system compared with the scanning spectral imaging, it has a great computational burden, often requires several minutes or even hours of iteration, and the reconstruction accuracy is relatively average.

The huge burden of data computing prompts people to think and look for more effective spectral reconstruction algorithms. In recent years, deep learning has developed rapidly, and the powerful pattern recognition and feature extraction capabilities of deep neural networks after good training have been favored by spectral imaging researchers. Deep learning methods have become the object of exploration, and deep learning has gradually empowered spectral imaging.

Methods of deep learning

The process of computational spectral imaging coding sampling system design and spectral image reconstruction, deep learning technology can be applied in every aspect of the process. How to effectively classify these different techniques is a key issue. The review proposes to classify according to the properties of light, that is, the computational spectral imaging system is divided into amplitude coding, phase coding and wavelength coding according to different coding methods.

(1) Amplitude-encoded spectral imaging

Figure 3: The spectral coding process in a coding aperture system

Amplitude-coded spectral imaging is achieved through a coded aperture system(CASSI)Conducted, using coding aperture(Amplitude mask)Amplitude coded spectral imaging based on deep learning replaces the iterative algorithm of compressed sensing recovery with deep neural networks, and performs efficient spectral reconstruction through codec co-optimization, iterative expansion neural networks, and untrained networks.

(2) Phase-encoded spectral imaging

Figure 4: A phase-encoded spectral imaging system

Phase-encoded spectral imaging through diffractive optics(Diffraction Optical Elements, DOE)Phase coding is achieved by designing the two-dimensional height profile of the DOE to achieve specific phase delays at different positions. Phase coding affects different spectral components through Fresnel diffraction, and then by modeling the diffraction process, the original spectral image can be reconstructed by the algorithm. Due to the complexity of diffraction calculation after phase coding, traditional iterative algorithms are difficult to achieve effective recovery of spectral images. This problem has been solved after the emergence of deep learning. At present, the spectral recovery of phase coding is mainly carried out through deep neural networks. Compared with amplitude coding, phase-encoded spectral imaging has the advantages of small light energy loss and compact system.

(3) Wavelength-encoded spectral imaging

Wavelength-encoded spectral imaging directly encodes the image in the spectral dimension and can be performed through optical filters. RGB images can be regarded as a kind of spectral coding. At present, the mainstream wavelength coding methods use existing RGB or design optical filters, and the encoded spectral reconstruction mostly relies on deep learning technology.

Direct spectral reconstruction based on RGB images is a very hot direction. With the NTIRE 2018 and NTIRE 2020 spectral reconstruction competitions, many deep learning technology teams participated, greatly expanding the existing deep learning spectral restoration techniques. The researchers analyzed the RGB spectral reconstruction and filter design spectral reconstruction involved in deep learning, and divided the reconstruction methods into point reconstruction and block reconstruction, so as to introduce each reconstruction method.

Wavelength coding based on custom optical filters is an emerging spectral imaging technology in recent years. By designing wide-spectrum filters, greater coding freedom can be obtained than RGB filters. Combined with effective deep learning technology, compact, fast and accurate spectral recovery can be achieved.

IV. Future Outlook

Based on current deep learning techniques and spectral imaging techniques, the researchers have made some suggestions for the future development of deep learning-based spectral imaging. These include the large-scale and normalization of datasets, and the use of large neural networks(For example Transformers)Introduce additional information such as object categories, solve the problem of layer disappearance in the process of codec collaborative design, and use neural networks architecture search technology.

Let’s read one article a day!Join >Light reading club

Recently, Hengda news constantly, Hengda real estate was investigated, workout stranded, executives were investigated one by one… The disposal of Hengda issues by regulators is constantly up the ante, Hengda, and the ending is getting closer and closer.

Evergrande cannot issue new bills

On the evening of September 24, China Evergrande released a bombshell message: in view of the fact that Evergrande Real Estate Group is being investigated, the current situation cannot meet the eligibility for the issuance of new notes.

There are relevant provisions for the issuance of bills by real estate enterprises. Article 8 of the "Pilot Measures for the Administration of Overseas Issuance of Securities and Listing of Domestic Enterprises" stipulates that there are five circumstances under which overseas issuance and listing shall not be allowed.One of them is that domestic enterprises are being investigated according to law for suspected crimes or major violations of laws and regulations, and there is no clear conclusion yet.

The "Hengda Real Estate Group is under investigation" mentioned in the announcement was on August 16 this year. Hengda Real Estate announced that it had received the "Notice of Filing a Case" issued by the China Securities Supervision Commission. Due to the company’s suspected information disclosure violations, the China Securities Supervision Commission decided to file a case against Hengda Real Estate.

In fact, after being investigated, he immediately knew that new bills could not be issued, and the announcement was made now, perhaps out of consideration for the resumption of trading in Hengda Hong Kong shares on August 28.

In addition, new notes cannot be issuedThat is, there is no way to issue bonds and borrow money, which means that Hengda’s blood transfusion pipeline is blocked from the financing end, and it also means that overseas workouts may end in failure.

Previously, Hengda’s workout voting meeting was pushed back and forth until September 22, when it directly announced that the workout meeting would not be held because sales were not as expected.

In March this year, Evergrande announced a restructuring plan for its $19.149 billion foreign debt, offering three options to creditors.

First, replace the old debt 1:1 with the new note,new billThe duration is 10 to 12 years.

Second, convert to a 5-9 year termnew billConverted into a combination of Hengda Property, Hengda New Energy Vehicles, or equity-linked notes linked to Hengda’s listed shares.

And thirdly,A combination of the above two…

That is to say, all three options require the issuance of new notes.

Now Hengda cannot issue new bills, financing channels are blocked, and workouts are also put on hold. It is clear that the Hengda issue has begun to close the net.

Many generals are being investigated

The first person to be taken away was Ke Peng, the former CEO of Evergrande Group. In January this year, he was taken away by the police for investigation because of his involvement in Hengda’s old reform in Shenzhen.

Shenzhen’s old renovation project was once regarded as Evergrande’s most important "ballast stone".

As early as 2016, Hengda’s financial report showed that it had 38 old renovation projects in Shenzhen, and the total value after all development would exceed 600 billion yuan. In 2019, Xia Haijun, then president of Hengda, once said that Hengda had 48 projects in Shenzhen, which was the largest developer of land reserves in Shenzhen, and the future income was unlimited. In 2020, Hengda’s financial report showed that Shenzhen accounted for 55 of the 104 old renovation projects laid out by Hengda.

But now it has been investigated, indicating that illegal activities may have been involved in the operation of these old renovation projects.

On September 16, Du Liang, general manager of Evergrande Wealth, and other suspected criminals were taken criminal coercive measures by Shenzhen public security. According to market news, the people arrested by Evergrande Wealth this time are all management.

Evergrande’s wealth is Xu Jiayin’s "money bag", which is used to provide financing for Evergrande’s own or related projects.

In August 2021, due to the difficulty of redemption, Evergrande announced that its financial products would stop selling to the outside world. According to the statistics of China Evergrande Group, from the initiation of financial products to the suspension of sales, the total amount of financing involved about RMB 92.10 billion yuan.

In September 2021, Evergrande’s wealth exploded, causing investors from all over the world to protect their rights. On September 10 of that year, Xu Jiayin publicly stated, "I can have nothing, but Evergrande’s wealth investors can’t have nothing. We must ensure that all maturing wealth products are repaid as soon as possible, not a penny less."

However, according to the "Internal Control Assessment and the Main Results of the Review of Certain Issues Raised by the Former Auditor" issued by Evergrande on August 24, 2023, as of December 31, 2022, Evergrande Wealth has not paid principal and interest of 34 billion yuan.

On August 31, Hengda Wealth once again issued a document saying that due to the lower than expected progress of asset disposal and the lack of asset disposal funds, it could not be redeemed for the month. From 8,000 yuan per month to 2,000 yuan per month, and then completely unable to redeem, in less than two years, Hengda Wealth’s cash flow has completely dried up.

Now it seems that Xu Jiayin’s lofty words at that time were nothing more than a delaying strategy, and now they cannot be repaid. Evergrande’s wealth may be suspected of crimes.

On September 21, Zhu Jialin, the former chairperson of Evergrande Life Insurance, was investigated.

Evergrande’s other purse is "Evergrande Life Insurance", which was fully taken over by Haigang Life Insurance, a newly established state-owned insurance company, due to serious insolvent.

In the heyday of Evergrande Life Insurance, it was responsible for "blood transfusion" for various businesses. Like Evergrande’s wealth routine, it sold high-yield universal insurance to attract the purchase of insurance products, and funneled the money to Evergrande’s real estate, automobile and other businesses through trusts and other means.

Hengda life is 2015 through the new Great Eastern Life Insurance changed its name, the total assets from 73.10 billion yuan in 2016 to 241.50 billion yuan in 2020, net profit has dropped from 1.243 billion yuan in 2017 to 333 million yuan in 2020, serious insolvent, the industry said its previous financial report may have problems, as the chairperson of Hengda life Zhu Jialin, may be involved.

On September 26, the latest news from Caixin English Network said that Xia Haijun, the former CEO of China Evergrande, and Pan Darong, the chief financial officer, have both been controlled or taken away.

Xia Haijun, the former president of Evergrande, is the most famous and responsible person in Evergrande besides Xu Jiayin, and is known as the "working emperor of the real estate industry".

Before Hengda’s thunder, the then president Xia Haijun immediately sold his holdings of Hengda dollar debt, cash 56.688 million dollars (about 360 million yuan), in 2021, Xia Haijun also successively reduced his holdings of Hengda property, Hengda Auto, Hengda RV Bao shares, a total of about 1.0155 billion Hong Kong dollars (about 827.20 million yuan).

In March 2022, Hengda Property was exposed 13.40 billion deposits were enforced, and with further investigation of the incident, the three executives involved, Xia Haijun, Pan Darong and Ke Peng, were asked to resign by the board of directors.

Xia Haijun has been the No. 2 figure in Evergrande for more than a decade. Major events in Evergrande’s development history are inseparable from Xia Haijun’s participation and decision-making, including Hengda’s financial management.

Xia Haijun and others were controlled by the relevant departments, which is a very obvious signal that the relevant departments have dealt with Evergrande, or have reached the stage of closing the net, even the executives who have left before cannot escape responsibility.

It’s hard to get back

With the "capable generals" around Boss Xu being caught one by one, Evergrande is not far from the finale.

Since Hengda’s explosion, the fire sale of Hengda’s shares, the "technical" divorce, and the filing for bankruptcy protection in the United States may pay for this series of "lying down" operations.

In the past six months, China Hengda has repeatedly disclosed that Hengda Real Estate is involved in major litigation and fails to pay off due debts. Among them, as of the end of July, Hengda Real Estate involves more than 30 million yuan in pending litigation, a total of 437.743 billion yuan in due and unpaid debts 2775.01 billion yuan, and a total of 207.50 billion yuan in overdue commercial tickets. Up to now, Hengda Real Estate has more than 600 information on the person subject to execution, and the total amount of execution exceeds 55.70 billion yuan. In addition, there are many restrictions on consumption orders, dishonest persons subject to execution (Lao Lai) and final case information.

Hengda since the second half of 2021 large-scale exposure to debt risk, nearly two years is still difficult to ease the pressure on funds, as of the end of June this year after excluding contractual liabilities of 1.78 trillion yuan, involving a large number of loans, payables, net assets negative 644.20 billion yuan. According to incomplete statistics, Hengda is currently involved in the country’s unfinished housing reached 1.60 million sets, which is behind 1.60 million families, close to 5 million people. The regulatory authorities left Xu boss time, or just to let him complete the task of "guaranteeing the building" as much as possible.Author | Wang Jian

　　On September 15, Geely’s new A-class SUV based on the CMA architecture – "Intelligent SUV Innovator" Boyue L, ushered in the first round of professional media static evaluation. At the same time, 8K ultra-high definition live broadcast sub-venues were opened in Beijing, Shanghai and other places. Thanks to China’s 5G communication technology and 8k ultra-high definition image quality, this ultra-high definition static evaluation perfectly demonstrates the beauty and workmanship of Geely Boyue L. It has a more detailed and clear visual sensory experience than the naked eye or even magnifying glass.

　　The novel tasting method and the exquisite texture of the Boyue L all made the "viewing" guests praise. The on-site media said one after another: "This time I didn’t come to the scene in person, but it was more real than seeing it on the spot, it was like using a microscope to see every detail of the body design and manufacturing. No matter the product or the form of the event, the’innovation ‘will be fully carried out to the end."

　　Under 8k, the slightest bit is visible, and the quality control of Boyue L is full of texture.

　　The Boyue L is the first production car based on the "Vision Starburst" concept car. It adopts the design concept of "Digital Symphony Technology Aesthetics" and is heavily integrated with the concept of technology, futurism and digitalization. With the support of 5G high-speed transmission and 8k ultra-high resolution, and a large cinema screen, the styling details of the Boyue L can be magnified hundreds of times, and the quality control of the workmanship can be more clearly displayed.

　　Boyue L’s light wave ripple front grille inherits the design characteristics of Geely’s classic "water drop ripple" in terms of shape, combined with new elements such as light sense, pulse, and ray, which has a strong technological taste. However, in terms of workmanship, it is necessary to vacuum quench and temper the mold material three times, polish it continuously for 25 days to achieve a mirror effect, and then spray the curved surface, mask 61 irregular discrete surfaces and 244 borders, etc., which is extremely difficult. Finally, under the precision production of Geely CMA factory’s high-precision equipment and ingenious craftsmanship, the light wave ripple front grille not only has a beautiful surface and boundary, but also uses electronic silver gray pearlescent paint to produce pearlescent effect under light, which is more three-dimensional and full visually.

　　Not only the front grille, Boyue L’s rich streamer light language and music light show are also more shocking and clearer on the high definition screen. The particle ray light group composed of 182 LED light-emitting units can be gradually lit or extinguished in the form of light waves in scenes such as welcome, send-off, lock car delay, etc., interpreting the deep sense of "Stargate" shape to the fullest. At the same time, the digital arrow LED through the tail light will also echo with the same visual effect. When lit, it is bright and transparent, giving users a sense of respect and ceremony while forming a high degree of recognition.

　　Luminous LOGO, tidal circulation waistline, 20-inch silver and black star disc wheels, etc., every detail of Boyue L shows the exquisite quality of the flagship level, which greatly enhances the user’s sensory value experience.

　　"Surround emotional light curtain" finishing touch, Galaxy OS Air version has smooth interaction

　　Take out the NFC card key and swipe it on the B pillar to unlock the Boyue L. After powering on the Boyue L cockpit, the most eye-catching is the world’s first "Surround Emotional Light Curtain", with 27 ambient light sets and LCD meters using an integrated design. During the live broadcast, the guests in the car experienced 8 major scenes such as door opening warning, music playback, nap mode, and voice interaction with the surround emotional light curtain. The 72-color tone ambient light showed a unique emotional interaction rhythm by simulating voiceprint, breathing, and water changes.

　　This live broadcast also conducted the first test of the Galaxy OS Air version of the car system launched by Boyue L. With the support of high-performance software and hardware such as Qualcomm Snapdragon 8155 chip, Flexray vehicle network and 13.2-inch central control vertical screen, the Galaxy OS Air version can be started and run in "seconds". What is even more surprising is that for the experience guests, "Open the car window – open the sunroof – fold the rearview mirror – reduce the temperature of the air conditioner – increase the air volume of the air conditioner – what is the weather like today – how is the stock market performing – play Jay Chou’s" Seven Lixiang "- open the seat heating – navigate to Tiananmen" and a series of complex instructions, the Boyue L car can be completed in only 25s, and the accurate voice recognition rate and execution rate are far beyond everyone’s expectations.

　　In terms of hearing, Boyue L is equipped with HARMAN Infinity’s Hi · Fi-class 11-sound unit sound system. In particular, the unique immersive headrest sound of the same class can realize the transmission of driving and entertainment signals, with independent sound source control, and has three modes of private, driving and sharing. The medical examination guests said that it effectively solves the pain point of interrupting music when navigating other models. When the co-pilot is riding, the system can automatically identify and intelligently switch to the driving mode according to gravity sensing. At this time, the navigation voice will be broadcast by the headrest sound, and the music will be played by other sound, so that navigation and entertainment will not interfere with each other, and create a personalized and private space for the main driver. When the co-pilot and rear passengers need to rest, they can switch to private mode, and only the headrest stereo can be heard in the whole car.

　　In addition, Boyue L is equipped with a double-color scheme super-sense racing antibacterial steering wheel, crystal diamond stopper, light and shadow sunglasses visor, HARMAN INFINITY luxury audio, immersive headrest audio, Air-sofa super-sense seat with adjustable leg support function and 8 major comfort functions, double-layer adjustable luggage, etc., convenient and comfortable humanized riding experience, but also left a deep impression on the reviewers.

　　Raytheon Hybrid + NOA empowers Boyue L’s intelligent driving experience

　　Due to the static evaluation this time, Boyue L’s intelligent driving and driving experience did not receive much experience, but it is still worth everyone’s expectation.

　　According to reports, Boyue L will be equipped with two sets of fuel powertrains, Drive-E series 2.0TD + 7DCT and 1.5TD + 7DCT. Among them, the 2.0TD engine can output a maximum power of 160kW and a maximum torque of 325N · m; the 1.5TD engine can output a maximum power of 133kW and a maximum torque of 290N · m. In addition, Boyue L will also launch a Raytheon Hi · F oil-electric hybrid version. The NEDC fuel consumption is only 4.2L/100km, and the NEDC comprehensive battery life can reach 1300km. There is no need to charge, and there is no mileage anxiety. It allows users to travel far in the city. Fully meet the diverse needs of different markets and different users.

　　At the same time, Boyue L will be equipped with GEEA 2.0 evolvable intelligent electronic and electrical architecture to achieve global FOTA in all scenarios and all vehicle cycles. Coupled with Boyue L’s first NOA lane-level autonomous driving pilot system, 25.6-inch giant screen AR-HUD head-up display system and Geely’s original "seven-layer intelligent safety identification circle", it will bring users a smarter, more energy-efficient and more performance driving experience.

　　It is worth mentioning that Boyue L is still an "entry-level high-end" product, and the whole series has "ten hardcore standard": Geely Galaxy OS Air version, 13.2-inch central control vertical screen, 10.25-inch digital LCD instrument, L2-level intelligent driving assistance system, 540 ° God’s Eye transparent chassis, mobile phone App remote control, aerospace-grade 7-series aluminum alloy collision beam, 178LX digital rhythm LED headlights, racing-grade braking system and integrated boron steel thermoformed door knocker.

　　Such a "smart SUV innovator" with outstanding visual effects and full of details has undoubtedly raised the standard of "smart SUV". With the opening of the Boyue L tasting activities in major cities across the country and the opening of store reservations, more and more consumers have joined the "fan group" of Boyue L, and more and more fans have become prospective users of Boyue L. The popular sales scene after its listing can be predicted.
