Three-Dimensional Mapping Technology Based on Tilt Photogrammetry with Light Single- Lens UAV

探讨了倾斜摄影测量原理及关键技术,提出了一种基于轻型单镜头无人机获得三维实景模型并通过EPS平台进行大比例尺地形图的生产方法,通过实例验证及精度分析,在平坦区域可满足1∶500地形图精度要求,适用于小面积、地物较复杂区域的大比例尺地形图测绘生产,在实际生产中有一定的指导意义。

The principle and key technology of tilt photogrammetry are discussed. The working method of building a three-dimensional real-world model based on light single-lens unmanned aerial vehicle and producing large-scale topographic map by EPS platform is proposed. Through example verification and precision analysis, the method can meet the accuracy requirement of 1∶500 topographic maps, and is suitable for large-scale topographic mapping of small area and complex terrain. The method is of certain guiding significance in practical engineering operation.
