Description

Technical Field

[0001] This invention relates to the field of vehicle document processing technology, and in particular to a method, apparatus, system, electronic device, and medium for inspecting vehicle-accompanying documents. Background Technology

[0002] In my country, automobile production must strictly adhere to the relevant parameters and standards declared by the Ministry of Industry and Information Technology for each vehicle model. After each vehicle rolls off the production line, various accompanying documents will be used to indicate the vehicle's relevant information and parameters to demonstrate that the vehicle meets the production standards. At the same time, a custom nameplate and identification code will be placed on the vehicle to identify its "identity" and facilitate traceability after the sale of the vehicle. Therefore, the accuracy and consistency of the vehicle's accompanying documents and information such as the nameplate are of paramount importance.

[0003] Conventional vehicle manufacturers typically set up dedicated workstations at the vehicle assembly line where personnel manually identify and compare information from relevant documents and nameplates.

[0004] In the process of realizing this invention, the inventors discovered that manual information identification and comparison has many defects. For example, due to the fast production cycle of vehicle manufacturing enterprises, the employees responsible for identification and comparison have a very high workload and intensity, which leads to a high error rate due to personnel ability and fatigue. In addition, there is no good way to record the information of the comparison process, resulting in poor traceability of the process execution results. Summary of the Invention

[0039] Example 1

[0040] Figure 1This is a flowchart of a vehicle accompanying document inspection method provided in Embodiment 1 of the present invention. This embodiment is applicable to situations requiring automated verification of the completeness and correctness of information in vehicle accompanying documents. The method can be executed by a vehicle accompanying document inspection device, which can be implemented in software and / or hardware, and is generally integrated into an electronic device. This electronic device can be a terminal device or a server device; the present invention does not limit the specific type of electronic device. Correspondingly, as... Figure 1 As shown, the method includes the following operations:

[0041] S110. Obtain the vehicle's accompanying documents for comparison data source.

[0042] Among them, the data source for comparing vehicle documents can be a set of vehicle documents determined based on the unique identifier of the vehicle to be tested.

[0043] In this embodiment of the invention, the vehicle document comparison data source for the vehicle to be tested can be determined based on the vehicle to be tested. Optionally, the vehicle document comparison data source may include at least one of the following: certificate of conformity, fuel label, and environmental protection list. Different vehicle models, different engines, and different power outputs carry different vehicle documents, and therefore the vehicle document comparison data source will also differ.

[0044] S120. Obtain the image of the vehicle file to be detected from the vehicle file to be detected, and identify the image of the vehicle file to be detected to obtain the first vehicle file data to be detected.

[0045] The images of the documents to be inspected can be images obtained by photographing or scanning the vehicle documents to be inspected using a camera. These documents may include vehicle registration certificates, purchase tax receipts, conformity certificates, fuel labels, and environmental protection lists, among other vehicle-related materials. The initial data of the vehicle documents to be inspected can be data obtained by processing the documents using image recognition methods.

[0046] In this embodiment of the invention, a camera can be used to acquire images of the vehicle documents to be inspected, and then the images of the vehicle documents to be inspected can be recognized to obtain the first vehicle document data to be inspected. The first vehicle document data to be inspected can be obtained using an image recognition method or an OCR (Optical Character Recognition) method to recognize and acquire the image of the vehicle documents to be inspected. In this embodiment of the invention, the specific recognition method for obtaining the first vehicle document data to be inspected is not limited.

[0047] S130. Obtain the image of the vehicle body identification of the vehicle to be detected, and identify the image of the vehicle body identification to obtain the second vehicle file data to be detected.

[0048] The vehicle identification mark to be detected can be an identifier that can uniquely identify the vehicle or other attribute information. The image of the vehicle identification mark to be detected can be an image obtained by photographing or scanning the vehicle identification mark on the vehicle body using a camera. For example, the vehicle identification mark can be a vehicle identification code. The second type of vehicle-accompanying document data to be detected can be data obtained by processing the image of the vehicle identification mark to be detected using an image recognition method.

[0049] In this embodiment of the invention, a camera can be mounted directly above the vehicle to be inspected. As the vehicle passes beneath the camera, the camera captures an image of the vehicle's identification markings. This image is then used to identify the second vehicle-accompanying document data. The acquisition of this second document data can be achieved using image recognition or OCR methods. This embodiment does not limit the specific method used to acquire the second document data.

[0050] S140. The first vehicle file data to be tested is compared with the vehicle file comparison data source, and the second vehicle file data to be tested is compared with the vehicle file comparison data source to obtain the vehicle file inspection result of the vehicle to be tested.

[0051] After obtaining the first and second vehicle-accompanying document data to be tested, the first and second vehicle-accompanying document data are compared with the vehicle-accompanying document comparison data source to obtain the vehicle-accompanying document inspection result of the vehicle to be tested. If both the first and second vehicle-accompanying document data successfully match the comparison data source, the vehicle-accompanying documents of the vehicle to be tested meet the requirements for completeness and correctness. If either the first or second vehicle-accompanying document data fails to match the comparison data source, the vehicle-accompanying documents of the vehicle to be tested do not meet the requirements for completeness and / or correctness.

[0052] The technical solution of this invention acquires a data source for comparing vehicle documents of the vehicle to be inspected, an image of the vehicle documents to be inspected, and an image of the vehicle body identification to be inspected. It then identifies the image of the vehicle documents to be inspected to obtain first data of the vehicle documents to be inspected, and identifies the image of the vehicle body identification to be inspected to obtain second data of the vehicle documents to be inspected. The first data of the vehicle documents to be inspected is then compared with the data source for comparing vehicle documents, and the second data of the vehicle documents to be inspected is also compared with the data source for comparing vehicle documents to be inspected to obtain the inspection result of the vehicle documents of the vehicle to be inspected. This solves the problems of low verification efficiency, error-proneness, and poor traceability in the prior art of manually inspecting vehicle documents. It saves labor costs while improving the efficiency, accuracy, and traceability of vehicle document verification.

[0053] Example 2

[0054] Figure 2 This is a flowchart of another vehicle accompanying document inspection method provided in Embodiment 2 of the present invention. This embodiment is based on the above embodiment and is further specified. In this embodiment, specific optional implementation methods are given for obtaining the vehicle accompanying document comparison data source of the vehicle to be inspected and for performing integrity verification on the vehicle accompanying document comparison data source. Correspondingly, as Figure 2 As shown, the method in this embodiment may include:

[0055] S210. Obtain the vehicle's accompanying documents for comparison data source.

[0056] In an optional embodiment of the present invention, obtaining the vehicle file comparison data source for the vehicle to be tested may include: obtaining the vehicle unique identifier of the vehicle to be tested; querying the vehicle file data source based on the vehicle unique identifier of the vehicle to be tested to obtain the vehicle file comparison data source.

[0057] The vehicle unique identifier (VUI) can be a unique identifier used to identify the vehicle to be inspected. The vehicle file data source can be a database of vehicle files that has a mapping relationship with the VUI of the vehicle to be inspected.

[0058] In this embodiment of the invention, the unique vehicle identification number (VIN) of the vehicle to be tested is first obtained. Then, the vehicle's accompanying document data source is queried based on the VIN, thereby obtaining the vehicle's accompanying document comparison data source. The vehicle's accompanying document data source may include at least one of the following: the vehicle's certificate of conformity, fuel label, and environmental protection list.

[0059] In a specific example, the unique vehicle identifier of the vehicle to be inspected can be the vehicle certificate number. The vehicle's accompanying documents data source can be queried based on the vehicle certificate number, thereby obtaining the accompanying documents comparison data source.

[0060] S220. Perform integrity verification on the accompanying vehicle files compared with the data source.

[0061] In an optional example of the present invention, performing integrity verification on the vehicle-accompanying document comparison data source may include: determining the benchmark documents included in the vehicle-accompanying document comparison data source; matching the comparison documents included in the vehicle-accompanying document comparison data source with the benchmark documents; and determining that the vehicle-accompanying document comparison data source passes the integrity verification if it is determined that each of the comparison documents included in the vehicle-accompanying document comparison data source matches the benchmark documents; the benchmark documents may include at least one of the following: a certificate of conformity, an environmental protection list, and a fuel label.

[0062] The benchmark file can be used to match the file to be compared, thus verifying the integrity of the data source for the comparison of vehicle-mounted documents. The file to be compared can also be used to match the benchmark file, thus verifying the integrity of the data source for the comparison of vehicle-mounted documents.

[0063] In this embodiment of the invention, the baseline files included in the vehicle document comparison data source are first determined, and then the comparison files included in the vehicle document comparison data source are matched with the baseline files. If the comparison files included in the vehicle document comparison data source and the baseline files can match each other, the vehicle document comparison data source passes the integrity check; if the comparison files included in the vehicle document comparison data source and the baseline files cannot match each other, the vehicle document comparison data source fails the integrity check. The baseline files may include a certificate of conformity, an environmental protection list, and a fuel label. The certificate of conformity may include information such as the vehicle model, vehicle equipment code, body color, engine number, and vehicle manufacturing date of the vehicle to be tested. The environmental protection list may include a vehicle identification number (VIN). The fuel label may include information such as vehicle type, VIN, engine number, and vehicle manufacturing date.

[0064] S230. Determine whether the vehicle-mounted file comparison data source has passed the integrity check. If yes, proceed to step S240; otherwise, proceed to S260.

[0065] S240. Generate an inspection instruction for the vehicle's accompanying documents.

[0066] Among them, the accompanying document inspection instruction can be an instruction used to instruct the accompanying documents to perform a comparison and inspection operation.

[0067] In this embodiment of the invention, if the vehicle-accompanying document comparison data source passes the integrity check, a vehicle-accompanying document verification instruction for the vehicle to be tested is generated; if the vehicle-accompanying document comparison data source fails the integrity check, a vehicle-accompanying document verification instruction for the vehicle to be tested is not generated.

[0068] S250, The vehicle document inspection command is sent to the first image acquisition and recognition device and the second image acquisition and recognition device.

[0069] The first image acquisition and recognition device is used to acquire and recognize the image of the document to be inspected in response to the vehicle document inspection command; the second image acquisition and recognition device is used to acquire and recognize the image of the vehicle body identification to be inspected in response to the vehicle document inspection command; the image acquisition and recognition device may include a fixed image acquisition and recognition device and a handheld image acquisition and recognition device; the fixed image acquisition and recognition device and the handheld image acquisition and recognition device are located on the same local area network. The fixed image acquisition and recognition device can be a device that can be installed in a fixed position to acquire images. The handheld image acquisition and recognition device can be a device that can acquire images while moving.

[0070] In this embodiment of the invention, the first image acquisition and recognition device and the second image acquisition and recognition device can be placed on the same local area network, and the first image acquisition and recognition device and the second image acquisition and recognition device can respectively respond to the vehicle document inspection command generated in the above steps.

[0071] Figure 3 This is a schematic diagram of the OCR camera body in a fixed image acquisition and recognition device according to Embodiment 2 of the present invention, as shown below. Figure 3 As shown, the OCR camera body consists of an OCR camera 310, a light 320, a power cord 330, and a bracket assembly 370. The bracket assembly 370 consists of a camera fixing device 340, a light fixing device 350, and a support base 360. The light 320 is connected to the light fixing device 350 and fixed to the support base 360. The light 320 is placed on the vehicle document to be inspected, so that the light can clearly illuminate the vehicle document to be inspected.

[0072] Figure 4 This is a schematic diagram of an image acquisition and recognition device provided in Embodiment 2 of the present invention, as shown below. Figure 4 As shown, the image acquisition and recognition device includes a fixed image acquisition and recognition device and a handheld image acquisition and recognition device. The fixed image acquisition and recognition device 430 is connected to the computer 420 via a transmission network cable 440. The computer 420 is connected to the display screen 460 via a video connection cable 450. Meanwhile, the handheld image acquisition and recognition device 410 and the computer 420 are placed in the same network environment.

[0073] Optionally, the fixed image acquisition and recognition device and the handheld image acquisition and recognition device can be placed in the same local area network, and the fixed image acquisition and recognition device and the handheld image acquisition and recognition device can respectively respond to the vehicle document inspection command generated in the above steps.

[0074] S260. Generate the verification result and end the verification.

[0075] In this embodiment of the invention, if the vehicle file comparison data source fails the integrity check, it indicates that the vehicle file comparison data source is unavailable. At this time, the computer will obtain the integrity check result of the vehicle file comparison data source to indicate that the vehicle file comparison data source of the vehicle to be tested does not meet the integrity requirement.

[0076] S270. Obtain the image of the vehicle file to be tested from the vehicle file to be tested, and identify the image of the vehicle file to be tested to obtain the first vehicle file data to be tested.

[0077] In this embodiment of the invention, when the first image acquisition and recognition device responds to the vehicle document inspection command, the first image acquisition and recognition device can acquire an image of the document to be inspected and recognize the image of the document to be inspected, thereby obtaining the first vehicle document data to be inspected. For example, when the fixed image acquisition and recognition device responds to the vehicle document inspection command, the OCR camera in the fixed image acquisition and recognition device can acquire an image of the document to be inspected and recognize the image of the document to be inspected, thereby obtaining the first vehicle document data to be inspected.

[0078] S280. Obtain the image of the vehicle body identification of the vehicle to be detected, and identify the image of the vehicle body identification to obtain the second vehicle file data to be detected.

[0079] In this embodiment of the invention, when the second image acquisition and recognition device responds to the vehicle document inspection command, the second image acquisition and recognition device acquires and recognizes the vehicle identification image to be detected, thereby obtaining the second vehicle document data to be detected. For example, when the handheld image acquisition and recognition device responds to the vehicle document inspection command, the handheld image acquisition and recognition device can acquire and recognize the vehicle identification image to be detected, thereby obtaining the second vehicle document data to be detected.

[0080] S290. The first vehicle file data to be tested is compared with the vehicle file comparison data source, and the second vehicle file data to be tested is compared with the vehicle file comparison data source to obtain the vehicle file inspection result of the vehicle to be tested.

[0081] In this embodiment of the invention, the first vehicle document data to be tested is sent to a computer for comparison with a vehicle document comparison data source, and the second vehicle document data to be tested is sent to the computer for comparison with the same data source, thereby obtaining the vehicle document inspection result for the vehicle under test. The obtained vehicle document inspection result is then displayed on a large display screen. For example, if both the first and second vehicle document data to be tested successfully match the comparison data source, the vehicle document for the vehicle under test satisfies both completeness and correctness requirements. If both the first and second vehicle document data to be tested fail to match the comparison data source, the vehicle document for the vehicle under test does not satisfy either completeness or correctness requirements. If both the first and second vehicle document data to be tested successfully match the comparison data source, the vehicle document for the vehicle under test satisfies completeness but not correctness requirements.

[0082] Figure 5 This is a schematic diagram of another image acquisition and recognition device provided in Embodiment 2 of the present invention, as shown below. Figure 5 As shown, the fixed image acquisition and recognition device 530 transmits the recognized file information to the computer 520 via the transmission network cable 540 for comparison and verification, obtaining the verification result. The handheld image acquisition and recognition device 510 transmits the recognized information and its comparison result to the computer 520. Furthermore, all comparison results are pushed to the display screen 560 via the video connection cable 550 for display. At the same time, all recognition information and all comparison results collected by the fixed image acquisition and recognition device 530 and the handheld image acquisition and recognition device 510 are stored in the computer 520.

[0083] Figure 6 This is a flowchart of another vehicle document inspection method according to Embodiment 2 of the present invention, as shown below. Figure 6 As shown, firstly, the OCR camera in the fixed image acquisition and recognition device identifies the vehicle identification code and accompanying documents to obtain the accompanying document information comparison data source. The computer then verifies the comparison source to obtain an integrity verification result. Next, the computer generates a verification task, and the OCR camera in the fixed image acquisition and recognition device identifies the accompanying documents, obtaining a comparison result through the computer. Further, the handheld image acquisition and recognition device identifies the vehicle body identification information, obtaining a comparison result through the computer. Finally, the accompanying document comparison data source, vehicle body identification information, accompanying document information, and comparison results are stored in the computer, and the verification comparison results are displayed on a large screen.

[0084] The technical solution of this invention first acquires the vehicle-accompanying document comparison database of the vehicle to be tested, performs integrity verification on the vehicle-accompanying document comparison data source, and generates a vehicle-accompanying document inspection command for the vehicle to be tested if the vehicle-accompanying document comparison data source passes the integrity verification. This command is then sent to a first image acquisition and recognition device and a second image acquisition and recognition device. Next, the image of the vehicle-accompanying document to be tested is acquired and recognized to obtain the first vehicle-accompanying document data to be tested. Then, the image of the vehicle body identification to be tested is acquired and recognized to obtain the second vehicle-accompanying document data to be tested. Finally, the first vehicle-accompanying document data to be tested is compared with the vehicle-accompanying document comparison data source, and the second vehicle-accompanying document data to be tested is also compared with the vehicle-accompanying document comparison data source to obtain the vehicle-accompanying document inspection result for the vehicle to be tested. This method saves labor costs while improving the efficiency, accuracy, and traceability of vehicle-accompanying document verification.
