Abstract: The control point layout scheme is an important part in the surveying stage of the unmanned aerial vehicle(UAV) oblique photogrammetry, which directly determines the accuracy of the later 3D real scene model. In this paper, aiming at campus and other small-area environments, and using the consumption-grade single-lens multi-rotor UAV aerial photography system to obtain the image data, different control point layout schemes are designed. Aerotriangulation and building 3D model based on automatic data processing system, accuracy analysis of model results is carried out. The suggestion and guidance are given for the layout of the control point in small areas for the actual work.

Key words: UAV oblique photogrammetry, control point layout scheme, 3D model, accuracy analysis, small area
