倾斜摄影测图下的地面特征点快速提取方法
A method for rapid extraction of ground feature points in oblique photogrammetry
摘要
Abstract
This paper addressed the issues of low efficiency in topographic map generation and underutilization of dense point clouds in oblique photogrammetry.A method was proposed for quickly and accurately extracting ground feature points from dense point cloud data generated by UAV oblique photography.This method also allows for the batch annotation of elevation points on topographic maps.Three different terrain areas were selected to test the method.Experimental results show that the method significantly improves work efficiency and the accuracy of results,especially in areas with exposed ground.It has practical value and contributes to the accumulation of engineering experience for solving similar issues in the future.关键词
