Abstract: The accuracy is an important indicator of the quality of UAV oblique photography three-dimensional(3D) model. Conventional modeling steps need to deploy ground control points (GCPs), which is inefficient and costly. Control-free modeling does not require GCPs, which is efficiency but low accuracy. Thus, this paper proposed a 3D modeling method of oblique photography with post-processed image control. The study area is in the east area of Nanjing University of Information Science and Technology. The results show that: 1) The accuracy of the 3D models established by the two methods is basically the same, and the plane error and the elevation error are both less than 0.05m, which meets the modeling requirements of high efficiency, high precision and low cost; 2) the photograph control post-processed modeling avoids the process of making and maintaining the photograph control point. photograph control points are selected on the existing high-precision 3D model and the coordinates are extracted, which improves the scientificity of the photograph control point selection and reduces the workload of setting GCPs; 3) This method has good universality in the regular updating of high-precision 3D real scene models in cities, towns, roads and other areas.
