DETAILED DESCRIPTION

[0033] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The enumerated embodiments are only used to explain the present invention and are not used to limit the scope of the present invention.

[0034] Reference Figure 1 This embodiment provides a vehicle windshield area recognition and detection system, which is arranged in a test room and includes a steam generating mechanism 1, a vehicle controller 2, a camera device 3, an indoor environment adjustment and monitoring device 4, and a computer 5. The steam generating mechanism 1 is connected to the vehicle controller 2 by signal; the vehicle controller 2 is connected to the target vehicle's driving computer and the computer 5 by signal; the camera device 3 and the indoor environment adjustment and monitoring device 4 are connected to the computer 5 by signal.

[0035] The steam generating mechanism 1 is used to generate steam in the cab of the target vehicle, so that the vehicle windshield can generate fog under human control, which is convenient for further testing the performance of the vehicle defogger system.

[0036] The vehicle controller 2 is used to control the start and stop of the steam generating mechanism 1 according to computer instructions; and to control the target vehicle, including the start and stop of the target vehicle engine, the defogger system, the raising and lowering of the window glass, etc.; monitor the operating parameters of the target vehicle, the operating parameters including but not limited to the engine speed, the battery power, the terminal voltage of the defogger system, etc.; and is also used to interact with the computer 5 for data, such as receiving control instructions from the computer 5, or transmitting recorded data to the computer 5.

[0037] The camera device 3 is used to collect windshield images and body images of the target vehicle at different test stages, and transmit the windshield images and body images to the computer 5 .

[0038] The indoor environment regulating and monitoring device is used to regulate the indoor temperature of the test room according to computer instructions and monitor the indoor room temperature and air flow rate of the test room.

[0039] The computer is used to control the system to run according to user preset instructions, record the test process, determine whether the target vehicle defogger system meets the requirements based on the windshield image, and automatically generate a test report based on the test process and the judgment result.

[0040] As a preferred embodiment, refer to Figure 2 The steam generating mechanism 1 includes a steam generator and a fixing mechanism. The steam generator includes a steam generating chamber 101, a diffusion chamber 102 connected to the steam generating chamber, and a centrifugal fan 103 connected to the diffusion chamber 102. The diffusion chamber 102 is connected to an exhaust hose 104. A heating device is provided in the steam generating chamber 101, and water is stored therein. The water is heated by the heating device to generate water vapor. After the water vapor enters the diffusion chamber 102, the centrifugal fan 103 extracts outside air and injects it into the diffusion chamber 102, so that the water vapor is discharged along the exhaust hose 104 under the push of the airflow.

[0041] The fixing mechanism is used to fix the exhaust hose 104 above the driver's seat reference point. The fixing mechanism includes a first telescopic part 105, a second telescopic part 106 and a third telescopic part 107, all of which are retractable. The end of the first telescopic part 105 is provided with a first clamping mechanism 108, and the first clamping mechanism 108 is used to clamp and fix the connecting rod of the target vehicle seat connected to the headrest. The second telescopic part 106 is perpendicular to the first telescopic part 105, the bottom of the second telescopic part 106 is connected to the top of the first telescopic rod 105, and the top is connected to the third telescopic part 107, and the second telescopic part 106 is used to adjust the height of the third telescopic part 107. The top of the third telescopic part 107 is provided with a second clamping mechanism 109, and the second clamping mechanism 109 is used to fix the exhaust hose 104. The bottom of the end of the third telescopic part is provided with a first distance sensor 110, and the first distance sensor 110 is connected to the vehicle controller 2 signal, and the first distance sensor 110 is used to detect the distance between the exhaust hose 104 and the seat surface of the car seat.

[0042] In this embodiment, the tester can use the fixing mechanism to conveniently fix the exhaust hose 104 connected to the steam generator 1 on the driver's seat, and the length and height of the fixing mechanism can be flexibly adjusted according to the differences in seats of different vehicle models, so the application range is wider.

[0043] Reference Figure 3 , the system is used to perform the following operations:

[0044] S101, the vehicle controller collects the target vehicle operating parameters, the indoor environment adjustment and monitoring device monitors the indoor temperature and air flow rate, the camera device collects the windshield image at time t1, and the computer determines whether the test conditions are met based on the target vehicle operating parameters, indoor temperature and air flow rate, and the windshield image at time t1. If so, execute the next step.

[0045] In this step, the windshield image at time t1 is the windshield image before the test begins, that is, the windshield image without fog, so that the subsequent steps can analyze the areas of region A and region B of the windshield based on the windshield image at time t1.

[0046] Exemplarily, the areas of region A and region B of the target vehicle may be obtained by a computer through analysis of a windshield image at time t1, or may be input into the computer in advance by a tester.

[0047] Area A refers to the main area of ​​the driver's field of vision, which is the central part of the vehicle's front windshield; Area B mainly refers to the part outside Area A, including the edge area of ​​the windshield.

[0048] The purpose of this step is to determine whether all the test start conditions have been met. If all are met, the test can be further carried out. Exemplarily, the test start conditions include but are not limited to: the distance between the exhaust hose 104 and the driver's seat reference point meets the regulations; the target vehicle engine coolant, lubricant and vehicle interior temperature are stable within the specified range; the indoor temperature and air flow rate meet the regulations; the windshield image is clear at time t1; whether the distance between the camera device and the target vehicle is within the specified range, etc.

[0049] S102, the steam generating device generates steam, and at time t2 the camera device collects the windshield image again. The computer identifies the windshield image at time t2 and determines whether the windshield of the target vehicle is covered by fog. If so, the next step is executed.

[0050] In this step, the windshield image at time t2 is the windshield image after the steam generating device has been working for a certain period of time during the test, but before the defogger system starts working. The purpose of collecting the windshield image at time t2 is to determine whether the windshield is completely covered with fog, so as to avoid the problem of inaccurate evaluation of the defogger system performance when the windshield is not completely covered with fog.

[0051] For example, the windshield image at the corresponding time can be collected after the steam generating device has been working for 5 minutes as the windshield image at time t2. If it is determined that the windshield is not completely covered by fog according to the windshield image at time t2, the windshield image is collected again after waiting for 5 minutes until the windshield is completely covered by fog. If the next step cannot be successfully entered after repeatedly collecting the windshield image for 3 times, an alarm is issued.

[0052] S103: The vehicle controller controls the target vehicle to start the engine and adjusts the target vehicle's defog system to a preset temperature.

[0053] S104. At time t3, the camera device collects the windshield image of the target vehicle and transmits it to the computer. The computer identifies the defogging area contour in the windshield image, determines whether the defogging area meets the requirements, and automatically generates a test report based on the test process and the judgment results.

[0054] This step collects the windshield image of the target vehicle at time t3 through the camera device, so that the computer can identify the defogging area contour based on the windshield image at time t3 and judge whether the defogging area meets the requirements. For example, the windshield image at the corresponding time can be collected 10 minutes after the start of the test as the windshield image at time t3.

[0055] For example, by analyzing the windshield image at time t3, if 90% of area A has been defogged and 80% of area B has been defogged, it can be considered that the performance of the target vehicle's defog system meets regulations and can ensure that the visibility of the windshield is restored under humid weather conditions.

[0056] As a preferred embodiment, refer to Figure 4 The camera device 3 includes a guide rail 301, a slider 302, a fourth telescopic rod 303, a pan-tilt head 304 and a first camera 305. The slider 302 is slidably arranged on the guide rail 301, and the fourth telescopic rod 303 is vertically arranged at the top of the slider 302. The pan-tilt head 304 is arranged at the top of the fourth telescopic rod 303, and the first camera 305 is connected to the pan-tilt head 304. A second distance measuring sensor 306 is arranged on the side of the fourth telescopic rod 303, and the second distance measuring sensor 306 and the first camera 305 are respectively connected to the computer 5 signal.

[0057] In this embodiment, the camera device 3 is located in front of the guide rail 301 during the test. The position of the fourth telescopic rod 303 can be adjusted by moving the slider 302, thereby adjusting the distance between the target vehicle and the first camera 305. The height of the first camera 305 can be adjusted by adjusting the length of the fourth telescopic rod 303, so that the first camera 305 can be easily moved to a reasonable position, so that it can use a fixed-focus lens with better clarity and sharpness. The second distance sensor 306 is used to measure the distance between the target vehicle and the first camera 305.

[0058] In this embodiment, the computer 5 includes a pre-experiment detection module, a defogging experiment control module, an image analysis module and a report generation module.

[0059] Among them, the pre-test detection module is used to determine whether the conditions for conducting the defog test are met based on the data transmitted by the vehicle controller, indoor environment adjustment and monitoring device, and camera device.

[0060] The defog test control module is used to control the steam generating mechanism, vehicle controller and camera device to carry out the defog test and record the test process data according to the user's preset instructions.

[0061] The image analysis module is used to input the windshield images of the target vehicle at different times into the neural network model for processing to obtain image analysis results, which include area A, area B, foggy area, non-foggy area, foggy area area and non-foggy area of ​​the windshield, and judge whether the performance of the target vehicle's defogger system meets the standards based on the image analysis results.

[0062] Exemplarily, the neural network model may adopt a pre-trained Faster R-CNN model, which can quickly and accurately locate the target object in the image and draw a bounding box to determine the position and size of the target, thereby calculating its area.

[0063] The report generation module is used to fill in the test report template according to the test process data, the analysis results and judgment results of the image analysis module, and automatically generate and output the experimental report.

[0064] As another preferred embodiment, the system further includes a second camera, the second camera is connected to the third telescopic part 107, and the computer 5 is connected to the second camera signal. The second camera is used to collect windshield images inside the target vehicle and transmit the windshield images to the computer 5. The computer 5 is also used to analyze the windshield images collected by the second camera and correct the judgment results according to the analysis results.

[0065] Specifically, the second camera provides a windshield image with a different viewing angle from that of the first camera. The computer 5 first inputs the windshield image captured by the second camera into the neural network model for processing to obtain an image analysis result, and corrects the image analysis result based on the image captured by the first camera with the image analysis result based on the image captured by the second camera to improve the accuracy of the analysis of different areas of the windshield and the fog elimination area, thereby accurately evaluating the performance of the target vehicle defogger system.

[0066] As another preferred embodiment, the computer 5 is further used to generate a digital watermark based on the recorded test process data, and add the digital watermark to the test report.

[0067] Exemplarily, generating a digital watermark based on the recorded test process data and adding the digital watermark to the test report specifically includes the following steps:

[0068] S201, converting the recorded test room environment data, target vehicle operating parameters, steam generation mechanism operating parameters, camera device operating parameters and other test process data and test personnel identity information into structured text;

[0069] S202, performing a hash operation on the structured text obtained in the previous step to obtain an operation result;

[0070] S203: embed the calculation result into the test report metadata to complete the addition of the digital watermark.

[0071] This implementation method first obtains the corresponding structured text based on various types of test process data, then performs a hash operation on the structured text, and embeds the operation result into the test report metadata as a digital watermark, so that it is possible to subsequently determine whether the test report content has been tampered with based on the digital watermark content, thereby ensuring the authenticity and verifiability of the test report.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
