Accuracy is an important indicator of the three-dimensional (3D) model of UAV oblique photography.Conventional modeling need to deploy Ground Control Points (GCPs),which is inefficient and costly.Control-free modeling does not require GCPs,which is efficient but not accurate.Here,we propose a 3D modeling approach for oblique photography with post-processed image control.The study was carried out in the east area of Nanjing University of Information Science & Technology.The results show that both the 3D models established by conventional modeling and post-processed image control modeling are accurate,with plane errors and elevation errors less than 0.05 m,meeting the modeling requirements of high efficiency,high precision and low cost.However,the post-processed image control modeling avoids the making and maintaining of the image control points,instead,it deploys the existing high-precision 3D model to select image control points and extract the coordinates.The proposed approach can be applied to regular updating of high-precision 3D real scene models for cities,towns,roads,etc.
