Laser sensors generally include a transmitter adapted to emit a laser beam at a target (eg, a vehicle), and a receiver adapted to receive laser light reflected from the target. The laser sensor can directly obtain the distance, angle, reflection intensity, speed and other information of the target by detecting the echo signal of the emitted laser, and generate a multi-dimensional image of the target. For example, the single-line lidar can calculate the distance between the single-line lidar and the target by measuring the round-trip time of the laser emission signal and the laser echo signal.

In an exemplary embodiment, the query module queries the predetermined parameters of the vehicle according to the determined front profile or the license plate number of the vehicle 100 . For example, the query module obtains the predetermined parameters by querying a local database or a network server set in the cloud.

In an exemplary embodiment, the predetermined parameters include a body length L4 and a trunk length L3 of the vehicle 100 under inspection. For example, the query module obtains the manufacturer, vehicle type, etc. of the vehicle according to the determined front contour or license plate number of the vehicle 100 , obtains the body length L4 through the data corresponding to the known vehicle type, and queries the information of the vehicle trunk database that has been filed. , get the trunk length L3 of the car.

's real-time location in the inspection area. It can be understood that the real-time distance L5 between the rear end 102 of the vehicle 100 and the scanning device 1 is:

L5=L1-L2

When the vehicle 100 is traveling upstream of the scanning device 1 toward the scanning device 1 along the traveling direction F, the real-time distance L2 between the rear end 102 of the vehicle and the position sensor 3 gradually increases. The front end 106 of the trunk 105 is about to enter the scanning area 16 of the scanning device 1 . In this case, the controller determines that the front end 106 of the trunk 105 of the vehicle 100 enters the scanning area 16 of the scanning device, and controls the scanning device 1 to scan and inspect the trunk 105 .

As the vehicle travels, if L5=0, it means that the rear end 102 of the vehicle 100 is about to leave the scanning area 16 of the scanning device 1 , and the controller controls the scanning device 1 to stop scanning and checking to avoid the next The driver of the vehicle scans for radiation. It can be understood that in the case where the position sensor 3 is disposed upstream of the scanning device 1 and the position of the vehicle is determined based on the rear end 102 of the vehicle 100, the distance L1 between the position sensor 3 and the scanning device 1 should be set larger than the vehicle The body length L4.

When the vehicle 100 travels upstream of the scanning device 1 toward the scanning device 1 along the traveling direction F, the real-time distance L2 ′ between the front end 101 of the vehicle and the position sensor 3 gradually decreases, and the vehicle body length L4 , and the position sensor 3 and the scanning device 3 gradually decrease. The distance L1 ′ between the devices 1 remains unchanged. When L5 ′=L3 , it means that the front end 106 of the trunk 105 of the vehicle 100 is about to enter the scanning area 16 of the scanning device 1 . In this case, the controller determines that the front end 106 of the trunk 105 of the vehicle 100 enters the scanning area 16 of the scanning device, and controls the scanning device 1 to scan and inspect the trunk 105 .

As the vehicle travels, if L5'=0, it means that the rear end 102 of the vehicle 100 is about to leave the scanning area 16 of the scanning device 1, and the controller controls the scanning device 1 to stop scanning and checking to avoid the following The driver of a vehicle scans for radiation. It can be understood that in the case where the position sensor 3 is provided upstream of the scanning device 1 and the position of the vehicle is determined based on the front end 101 of the vehicle 100, the distance L1' between the position sensor 3 and the scanning device 1 should be set larger than the vehicle The body length L4.
