Therefore, in order to ensure road traffic safety, it is essential to detect the vehicle outer dimension compliance.

At present, detection devices developed from laser radars are widely used in various situations of vehicle overall dimension detection due to the characteristics of high precision, strong environmental interference resistance and high response speed. The laser radar belongs to a precision measuring instrument, has higher manufacturing cost and harsher use conditions, so in order to ensure the precision, the radar equipment needs to be cleaned and maintained regularly, and the fault radar needs to be replaced in time. However, the existing solutions for the vehicle overall dimension detection device with the laser radar fix the laser radar on a portal frame beam or a building wall.

In the solution described above, on the one hand, the lidar is directly mounted on the fixed structure by a hard connection. In this manner, when the fixed structure is displaced a small amount, the lidar is likely to be out of the detection range due to a change in the fixed point. Under the condition that the problem can be solved only by finely adjusting the radar, large-scale disassembly and assembly and maintenance are carried out, the cost is high, the consumed time is long, and the method is obviously unsuitable. On the other hand, since the vehicle to be detected is usually a truck, a muck truck, a tank car, a transportation vehicle for dangerous goods, etc., and the vehicle has a large size and a height of 4 meters or more in general, the laser radar installation height is required to be 5 meters or more in general.
