Pavement flatness measurement method and system
Abstract The present invention discloses a method and system for detecting road surface flatness, which belong to the technical field of road surface detection. The method 5 comprises: acquiring road surface three-dimensional point cloud data; performing reverse modeling by using the point cloud data to obtain a road surface entity model; building an eight-wheel flatness measuring instrument model in equal proportions, and constraining connection relationships of respective components; enabling the eight-wheel flatness measuring instrument model to move on a 10 specified characteristic line of the road surface entity model by using a motion simulation technology to obtain a road surface unevenness deviation value of each measurement interval; and calculating a flatness value of the road surface according to the road surface unevenness deviation value. The present invention has simple principles and strong feasibility, and can meet the requirements for the 15 flatness detection of various road surfaces, especially basin-shaped curved road surfaces in test (race) yards. (Fig. 1)
