倾斜摄影测量在城市数字化三维建模中的应用

文章以广场区域为主要的观测对象,使用多旋翼类型的无人机装置配备有五镜头型号相机的方案来捕捉相关区域的倾斜角度的图像数据,借助像控点的测量、密集类型的图像匹配、空间区域的三角测量、网平差计算、密集类型的点云构造、三角网格的生成、纹理皮肤的映射、数字模型的加工修整等等操作,实现城市区域三维空间数字化建模和既有数据的更新。并对单体类型的技术、图形精修、自动分层技术等领域实施进一步的探索。

In this paper,taking the square area as the main observation object,the multi-rotor type UAV is equipped with a 5-lens camera to capture the image data of the tilt angle of the related area.With the help of image control point measurement,dense type image matching,spatial region triangulation,network adjustment calculation,dense type point cloud construction,triangle mesh generation,texture skin mapping,and digital model processing,this study realizes the urban area 3D space digital modeling and the update of the existing data,and carries out further exploration in the fields of monomer type technology,graphic refinement,and automatic slicing technology.
