Abstract: In the 3D reconstruction of urban scene, using UAV to collect images at low altitude has become the mainstream scheme. The UAV captures images at low altitude based on the optimal aerial path can improve the accuracy and efficiency of 3D reconstruction. Therefore, many researchers have investigated and developed the UAV aerial path planning methods in recent years. Accordingly, many viewpoint planning and flight path planning approaches have been reported. To summarize the principles of these new methods, this paper describes the working process of aerial path planning techniques, and details the modeling methods of aerial path planning based on the reconstructed 2D and 3D models of environments, as well as the unknown environment. Then the advantages and disadvantages of different path planning methods are analyzed, and the development trends are also discussed. This review can provide an important reference for the development of UAV control, aerial photography technology, and 3D reconstruction of large-scale scenes.

Key words: UAV, 3D reconstruction, oblique photography, aerial path planning, viewpoint planning
