Road rut detection system with embedded multi-channel laser sensor

Laser sensing technology is used to detect the pavement. In the pavement cross-section rut detection, multi-channel laser sensors are used to collect the three-dimensional information of the uneven cross-section direction of the road surface at the same time. In the pavement structure depth detection, two laser sensors are used to collect the three-dimensional information of the road surface structure depth at the same time. Linear regression and quadratic regression algorithm are used to reduce the pavement cross-section rut and structure depth detection. On this basis, the embedded multi-channel laser pavement rutting detection system and laser pavement structure depth detection system are researched and developed; many field tests and application tests have been carried out. Through comparison and verification, the system has strong reliability, small error, and fast detection speed, which is suitable for road detection of different structures.
