Research on 3D Modeling of High Pier Bridges in Mountainous Areas Based on UAV Refined Route Planning
The refined route planning and fast modeling method for high-pier bridges in mountainous areas and the quantification method of pier geometric parameters based on point cloud are introduced.First,a rough oblique photographic model of the bridge is established by using a UAV circular route.Then,a refined route is planned and high-resolution images are collected based on the rough model.Finally,a refined 3D point cloud model of the bridge is established and the geometric parameters of the bridge piers are quantified.Through practice in projects,it is found that the refined route can effectively improve the accuracy of bridge 3D point cloud modeling.Based on the refined pier point cloud model to quantify the geometric parameters of the pier,the quantification errors of the radius,height,and volume of the pier are within 2％,5％and 8％,respectively.
