| Abstract: | In recent years,fast 3D modeling based on UAV tilt image has become a new technology in the field of surveying and mapping.According to the principle of tilt photogrammetry,the three-dimensional model of Yunnan normal University campus is constructed by using Smart3D Capture,and the precision analysis of the extracted feature points is carried out.The accuracy of building,road and flower bed are 0.18 m,0.19 m and 0.15 m,which can meet the requirements of large scale accuracy,and using this method to carry out large scale digital mapping in difficult areas has certain application value. |
