Precision three-dimensional pavement faulting measurement method and apparatus

Abstract

A precision three-dimensional pavement faulting measurement method includes: acquiring three-dimensional pavement contour data; based on the three-dimensional pavement contour data, obtaining a contour reference surface and a contour deviation between measuring points in the three-dimensional pavement contour data and the contour reference surface; based on the contour deviation, obtaining a suspected joint point; based on the suspected joint point, obtaining a suspected joint denoised binary image; based on a row direction projection feature of target measuring points in the suspected joint denoised binary image, obtaining an original joint target image and a joint representative position; based on the suspected joint denoised binary image, the original joint target image, and the joint representative position, obtaining a target joint binary image by means of a joint extension operation; and based on the target joint binary image and the three-dimensional pavement contour data, obtaining pavement faulting information.
