摘要
文中以旋翼无人机倾斜摄影测量系统为基础,建立高分辨率、高精度三维实景模型,并基于此三维模型进行数字化测图生产研究。结果表明:带有真实地理位置坐标的三维实体模型几何精度以及基于此模型生产的DLG几何精度(平面和高程)均满足1:500地形测绘精度需求。
In the paper,high-resolution and high-precision 3D real-scence models were built on the basis of Rotor UAV oblique photogrammetry system,digital mapping production research was carried out based on the 3D model.The result indicated that: the geometric accuracy of 3 D real-scence model with real geographical position coordinates and the geometric accuracy( plane and altitude) of DLG produced on the basis of the model were all meet the accuracy requirements of 1: 500 topographic mapping.
