Bridge surface roughness model determination method based on three-dimensional laser point cloud scanning technology
The invention discloses a bridge floor roughness model determination method based on a three-dimensional laser point cloud scanning technology. The method comprises the following steps: step 1, determining a bridge floor scanning area; 2, setting a target ball; step 3, scanning and obtaining bridge deck point cloud data; step 4, preprocessing the point cloud data of the bridge floor; step 5, acquiring a normalized integral bridge deck point cloud matrix; and step 6, establishing a bridge floor roughness model. According to the method, the bridge floor roughness model is accurately and quickly established according to actual conditions, the defect that the bridge floor roughness model in the existing international standard ISO8608 lacks authenticity is overcome, and the established model can be integrated with a bridge model to form a whole bridge model with real bridge floor roughness. According to the method, the bridge floor roughness model can be accurately established especially for a seriously damaged bridge floor, the three-dimensional space form of the bridge floor can be completely reconstructed with high precision, the method is used for analyzing and verifying a real bridge and timely finding the problems of apparent deformation, internal damage and the like of an in-service bridge, and a new thought is provided for daily operation, management and maintenance of the bridge.
