Abstract
UAV tilt photogrammetry technology has unique advantages such as high efficiency and convenience in the three-dimensional modeling,and has become a popular measurement technology.In order to discuss the accuracy of three-dimensional modeling of UAV tilt photogrammetry,this paper expounds the principle and process of three-dimensional modeling of UAV tilt photogrammetry.Taking a historical building as the research object,the DJI 4 RTK UAV is equipped with high-resolution images to fly around the target,collect the facade images of each orientation,and construct the three-dimensional model.The residual size of the reconstructed E,N and U coordinates and the coordinates of the measured control points and accuracy analysis are studied.The results show that the three-dimensional modeling accuracy in the study area reaches centimeter level,which can be effectively used in industries such as construction planning,cultural relic protection and restoration.关键词
