UAV倾斜摄影在革命旧址保护中的应用
Application of UAV Oblique Photogrammetry in the Protection of Revolutionary Sites
摘要
Abstract
In view of the severity of protection work of revolutionary sites,and the low efficiency of traditional surveying and mapping methods in obtaining the survey area data,based on UAV oblique photogrammetry technology,taking the revolutionary sites of Red Army Long March as the research object,through field data collection,we used SIFT algorithm to extract and match the image feature points,used SfM-MVS algo-rithm to build 3D scene,and collected the checkpoint data in the 3D scene.The results show that 3D scene can meet the requirements of large-scale digital topographic map.Furthermore,through the accuracy analysis of line elements,it can be obtained that the measurement results of 3D scene data reach centimeter level,which meets the requirements of data accuracy in the protection of revolutionary sites,and can provide a variety of basic data in the protection of revolutionary sites,which provides an efficient reference method for obtaining high-precision data in the protection of revolutionary sites in the future.关键词
