Pavement flatness measurement method and system
A pavement flatness measurement method and system. The measurement method comprises: acquiring three-dimensional point cloud data of a pavement; performing reverse modeling by using the point cloud data to obtain a pavement entity model; building an eight-wheel flatness measuring instrument model in equal proportion, and constraining the connection relationship of all parts; enabling the eight-wheel flatness measuring instrument model to move on a specified characteristic line of the pavement entity model by using a motion simulation technology, to obtain a pavement irregularity deviation value of each pavement measurement interval; and calculating the flatness value of the pavement according to the pavement irregularity deviation value. The system comprises an acquisition module (10), a pavement entity model building module (20), a flatness measuring instrument model building module (30), a pavement irregularity deviation value calculation module (40), and a flatness calculation module (50). The measurement method and system can be applied to curved pavements and large-slope pavements, and has strong feasibility and practicability.
