Abstract: In the production of high-precision 3D real scene models, the selection of UAV platforms and loads and the laying of image control points are of great importance, which affect the efficiency of aerial photography, model accuracy, and model effects. In this paper, an urban village in north of China is used as a research area, and different UAV oblique photogrammetric equipments are used to obtain oblique images of the same resolution respectively, and combined with different image control point laying schemes to reconstruct the 3D model of the real scene. Through different equipment and image control point laying combinations, and original images of the same resolution, a test group is formed to compare and analyze flight efficiency, model accuracy and model effect. Thus, equipment selection and economical and reasonable image control point layout for meeting high-precision 3D real scene model reconstruction requirements are studied so as to provide guidance for actual production operations.

Key words: oblique photography, 3D real scene model, image control point layout, UAV platforms and payloads
