Claim 5:
6. The intelligent safe vehicle speed measurement system capable of considering the state of the road surface according to claim 1, wherein the laser scanning unit comprises a laser, a first camera, a second camera, a computer, a cantilever, and a crossbeam; the laser is installed in a middle of the crossbeam; and the first camera and the second camera are located at two ends of the cantilever, respectively; and
the laser is configured to emit infrared laser light, the first camera and the second camera are configured to receive reflected infrared laser light and transmit data back to the computer to obtain the texture of the road surface, and the computer is configured to perform the stress simulation on the vehicles with the variety of loads and tire patterns through a preset finite element program to update the tire-road surface contact relationships and the corresponding braking distances stored in the system.
