Research on Aerial View Point Planning of Drone based on Multi-View

For multi-view viewpoint planning research, Firstly, using the UAV aerial multi-view image, the viewpoint view is first to establish a candidate view area according to the shooting distance. Secondly, the sub-viewpoint set is filtered and the view points are complemented by the region where the candidate view cannot be photographed, so that the three-dimensional reconstruction data has better integrity. Thirdly, the influence of camera incident angle on image pixel error is analyzed, and the corresponding 3D model is established. Finally, the stereoscopic overlap is used to perform viewpoint screening under the premise of ensuring image quality and shooting coverage. The experimental results show that the proposed viewpoint planning method has high coverage and the reconstruction accuracy is below 0.1% of the target size.
