基于倾斜摄影测量的校园建筑物三维模型构建
Construction of Campus Structure 3D Model Based on Oblique Photogrammetry
摘要
Abstract
With the development of unmanned aerial vehicles and oblique photogrammetry technology,the accuracy and efficiency of 3D real scene modeling have been greatly improved.This article,based on unmanned aerial vehicle tilt photogrammetry technology,constructs a high-precision and measurable three-dimensional model of Hebei University of Water Resources and Electric Engineering.Based on the regional situation of Hebei University of Water Resources and Electric Engineering,10 ground control points and 16 reference points were set up.DJI Phantom 4 RTK was used for tilt photogrammetry to construct a three-dimensional model of the campus.The problems of model rupture,faults,and incomplete data collection of buildings with high tilt photogrammetry after aerial triangulation were analyzed and solved.With the help of model modification software,the real 3D model of Hebei University of Water Resources and Elec-tric Engineering was modified to address issues such as water surface damage,model vulnerabilities,and blurred texture of billboards.In order to solve the problem of voids caused by high floors in the library building,a high-precision individual model was obtained through a separate close-up photogrammetry.The accuracy analysis of the repaired model was conducted from the perspectives of relative and absolute accuracy,and a realistic 3D model with a mean square error of 3.6cm in plane and 5.1cm in elevation was obtained.关键词
