Research and Application of Rapid 3D Modeling Technology based on UAV

The main disadvantages of the traditional tilt photography modeling engine are that the modeling takes a long time, the three-space solution is easy to fail, and the modeling process requires manual intervention, lack of timely control of the scene, not suitable for the emergency rescue in a race against time. The rapid 3D modeling method proposed in this paper improves the timeliness of 3D modeling on the premise of ensuring the modeling accuracy and effect by optimizing each stage of route planning, data acquisition, image preprocessing, aerial triangulation and 3D reconstruction, and the feasibility of the method is verified by experiments.
