Exploration of the Application of Multi Photogrammetry Technology Fusion in Complex Terrain Realistic 3D Modeling
This paper points out that the 3D modeling of complex terrain is one of the research hotspots in the field of geographic information science and computer vision,but the traditional oblique photogrammetry is difficult to accurately reconstruct the detailed features of complex terrain.In this paper,the method of fine 3D model of complex terrain is proposed and studied by combining UAV photogrammetry with ground close-up image.The practice shows that the detailed 3D model constructed by the multi-photogrammetry technique proposed in this paper has good visualization effect and high precision,and can effectively solve the impact of complex landform conditions such as terrain height difference on the quality of real scene modeling.
