Embodiment
[0044] In order to verify the effectiveness of the method, in the virtual simulation platform environment, the 3D reconstruction experiment under the positioning of the flying camera, the evaluation of the image field of view loss and the reselection of the key frame is carried out, and the 3D static region of interest can be obtained from the commercial satellite data artificially. The digital elevation model (DEM) of the aircraft is represented in the form of point cloud, and the flight trajectory planned in the previous stage is obtained based on the shooting constraints of the equidistant orthographic view.
[0045] Example:
[0046] Such as figure 1 , 2 As shown, this embodiment will check the effectiveness of the method based on the process, including the following specific steps:
[0047] Step 1: Use the equidistant orthographic constraint to plan the shooting trajectory of the UAV to achieve the desired 3D reconstruction optimization effect;
[0048] Step 2: Positio...
