摘要
无人机倾斜摄影测量是以无人机为低空航摄平台,获取正视和倾斜多个视角的二维相片,用以重建地物与地貌的三维模型。其模型精度和纹理清晰度取决于二维相片的分辨率和差异。基于倾斜摄影的成像原理,推算了多视角相机的分辨率数学模型,以指导倾斜视角的设计和航摄规划。
UAV oblique photogrammetry based on UAV low aerial platform, can get multi-angle(vertical and oblique) 2D images, to reconstruct 3D models of objects and landforms. The accuracy of the model and the clarity of texture depend on the resolution and differences of 2D images. In this paper, we calculated image resolution model of the multi-angle camera, to guide the design of tilt angle and the plan of aerial photography.
