Title:
VEHICLE CHECK SYSTEM AND VEHICLE CHECK METHOD
Document Type and Number:
WIPO Patent Application WO/2024/088017
Kind Code:
A1
Abstract:
A vehicle check system and a vehicle check method. The system comprises a first vertical-plane laser beam detection device (LV), which emits a first vertical-plane laser beam perpendicular to a check passage and receives a reflected laser signal so as to detect the outer contour of a vehicle; and a first horizontal-plane laser beam measurement device (LH1) that emits a first horizontal-plane laser beam in the horizontal direction along the extension direction of the check passage and receives a reflected laser signal so as to measure the vehicle body position and the speed of the vehicle. The vehicle check system determines that a vehicle starts to enter a detection area on the basis of the detection of the first vertical-plane laser beam detection device (LV), and determines the position and speed of the vehicle in the detection area on the basis of the measurement of the first horizontal-plane laser beam measurement device (LH1), thereby determining the moment of starting checking the vehicle.
