Pavement abrasion detection method based on precise three dimensions
The invention relates to the technical field of pavement detection, and provides a pavement abrasion detection method based on precise three dimensions, which comprises the following steps: receiving original pavement elevation data and original pavement gray scale data of each measurement point on a road acquired by a line scanning three-dimensional measurement sensor, the measurement range of the line scanning three-dimensional measurement sensor covering the whole lane width; determining a lane line position, and extracting target pavement elevation data and target pavement gray scale data in a lane range; reconstructing pavement three-dimensional point cloud data; based on the reconstructed road surface three-dimensional point cloud data, determining a road surface full-width structure depth by combining a preset road surface structure depth calculation model; based on the lane line position and the road surface full width construction depth, determining the positions of a left wheel track belt, a right wheel track belt and a lane center line; and calculating the pavement abrasion based on the pavement full width construction depth and the respective positions of the left wheel track belt, the right wheel track belt and the lane center line. According to the invention, the pavement abrasion can be accurately detected, and the pavement abrasion at any position of the pavement can be detected.
