[0031] Working Principle: In the specific implementation of this invention, the main body of the base 100 is constructed using steel welding and assembled on-site. Local horizontal adjustments are possible. AVM calibration of the 500 AVM target is primarily achieved through ground-based targets. Based on actual project analysis, the target in this solution utilizes matte UV printing technology with a metallic coating. The vehicle moves from the base 100 to the upper side of the positioning device 200. Guided by the guide rod 240, the vehicle moves to the front wheel placement device 220. The front wheel placement device 220 stops at its limit, with the front wheels resting on the upper side of the first rotating rods 222 on both the front and rear sides. The inclined setting of the upper side of the first rotating rods 222 on both the front and rear sides limits the movement of the vehicle's front wheels. The front wheel placement device 220 effectively limits the movement of the vehicle's front wheels. The rear wheels of the vehicle are positioned above the second rotating rod 232. An oil receiving pan 250 collects any oil spillage that may fall from the lower side of the vehicle. The left and right positions of the front and rear wheels are adjusted by the straightening device 260. Two sets of first cylinders 262 are activated, causing the two sets of straightening plates 263 to move away from each other. When the two sets of straightening plates 263 move away from each other, they are limited by a slider on the lower side of the straightening plates 263. Under the limit of the first connecting plate 273, the rotating plate 272 rotates, ensuring that the two sets of first connecting plates 273 operate synchronously, preventing them from swaying on both sides. The two sets of straightening plates 263 compress the vehicle, causing the two sets of straightening plates 263 to... Three vehicles are aligned. With the central axis of the third rotating rod 271 as the center, the wheels on both sides slide on the upper side of the first rotating rod 222 or the second rotating rod 232 under the limitation of the two sets of alignment plates 263, thereby fixing the left and right positions of the four vehicles. The laser measurement and detection device 300 serves the process requiring strict vehicle posture detection, aligning the vehicle body with relevant hardware devices. An embedded controller is used to integrate these into a centering platform control system. After the vehicle is aligned, the 360-degree camera on the vehicle captures images of the surrounding targets and uploads them to the host computer. The host computer then analyzes the images to obtain test results. When using the laser measurement and detection device 300, the front wheel arch measuring device 310 detects the wheel arches of the front wheels, which can measure... The height of the front wheel arches is measured, and the height of the rear wheel arches is measured using the rear wheel arch measuring device 320. The second cylinder 316 is activated, which moves the second connecting plate 317 forward. The second connecting plate 317 then moves one side of the second support frame 314 forward, while the other side of the second support frame 314 rotates around the fourth rotating rod 313. This allows the first laser sensor 315 to move from the side of the first protective box 318 near the base 100 to the rear side of the first protective box 318. The position of the first laser sensor 315 is adjusted as needed so that after the vehicle is parked, it moves to the left and right sides of the front wheels. Once the first laser sensor 315 has completed its measurement of the front wheels...The first laser sensor 315 moves to the rear of the first protective box 318 to facilitate vehicle removal. The first motor 324 is activated, driving the screw 323 to rotate. The screw 323 rotates, causing the loop block 325 to move back and forth. This movement of the loop block 325 then moves the third support frame 327 and the second laser sensor 328 back and forth to accommodate vehicles of different lengths. Since the vehicle is limited by the front wheel mounting device 220, the front-side position of the first laser sensor 315 does not need adjustment. However, for vehicles of different lengths, the rear wheel positions differ. Activating the first motor 324 moves the second laser sensor 328 back and forth, activating the third cylinder 329. The third cylinder 329 drives the third connecting plate 330 forward, which in turn moves one side of the third support frame 327 forward. This causes the other side of the third support frame 327 to move the second laser sensor 328 to the rear of the second protection box 331. The second laser sensor 328 then detects the rear wheels of the vehicle. After the vehicle is parked, the second laser sensor 328 moves to the vehicle location and, after completing its detection, moves to the rear of the second protection box 331. Once the vehicle is parked, the combined gantry crane device 410 is activated. This device moves the ultrasonic sensor 460 and the checkerboard target 470 left and right, and the Y-axis moving device 420 is activated. The ultrasonic sensor 460 and the checkerboard target 470 are moved up and down by the Y-axis moving device 420. The Z-axis moving device 430 is activated, moving the ultrasonic sensor 460 and the checkerboard target 470 back and forth. The six-axis collaborative robot 440 is activated, adjusting the position of the ultrasonic sensor 460 and the checkerboard target 470. The combined gantry crane device 410, Y-axis moving device 420, Z-axis moving device 430, and six-axis collaborative robot 440 work together to move the ultrasonic sensor 460 and the checkerboard target 470 to the driver and passenger positions of the vehicle for detection. Depending on the project requirements, the ultrasonic sensor 460 and the checkerboard target 470 are mounted... The system underwent real-vehicle testing and exhibits high safety, flexibility, and precision.

[0033] AVM Test: The car is driven onto the positioning device 200. After the positioning device 200 straightens the car, the 360 ​​camera on the car will take pictures of the AVM targets 500 around it, and upload the pictures to the host computer. The host computer will then analyze the pictures and obtain the test results.

[0034] DMS Test: The vehicle is driven to the positioning device 200. After the positioning device 200 straightens the vehicle, the laser measurement and detection device 300 extends to identify the vehicle's posture and feeds it back to the host computer. The host computer then controls the driver's seat detection device 400 to enter the designated position inside the vehicle. A checkerboard target 470 is installed at the front end of the driver's seat detection device 400. The camera of the DMS on the vehicle takes a picture of the checkerboard target 470, acquires the image, and uploads it to the host computer. The host computer then analyzes the image and obtains the test results.

[0035] HUD Test: The car is driven onto the positioning device 200. After the positioning device 200 straightens the car, the laser measurement and detection device 300 extends to identify the car body posture and feeds it back to the host computer. The host computer then controls the driver's seat detection device 400 to enter the designated position inside the car. The robotic arm is equipped with a substitute device 490 (camera). After the HUD is turned on, the camera acquires images and uploads them to the host computer. The host computer then analyzes the images and obtains the test results.
