3D modeling method for real scene of buildings based on UAV image

This paper describes the current development status of three-dimensional (3D) modeling of buildings, and discusses a method of constructing 3D modeling of real-scene buildings by combining an unmanned aerial vehicle oblique image and orientation system (POS) data. The quality and effect of real-scene 3D model modeling are guaranteed by POS aided aerial triangulation, digital surface model construction, real-scene 3D model generation and refined correction of 3D model. The test results show that the constructed real-scene 3D model has high precision, clear texture and small geometric deformation.
