摘　　要：介绍了针对山区高墩桥梁的精细航线规划及快速建模方法和基于点云的桥墩几何参数量化方法。采用无人机环形航线建立桥梁的粗略倾斜摄影模型,基于粗模规划精细化航线并采集高分辨率图像,建立桥梁精细化三维点云模型,并量化桥墩几何参数。通过实际工程应用发现,无人机精细化航线能有效提高桥梁三维点云建模的准确度,且基于精细化桥墩点云模型可量化桥墩几何参数,所得的桥墩半径、高度及体积的量化误差分别在2%、5%和8%以内。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 3Dpoint 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 3Dpoint 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.
