徕卡ADS 80数字航空相机采用POS/GPS精确导航定位技术进行航空摄影,通过对GPS差分数据进行常规布设控制点、少量布设控制点甚至无控制点的内业空三解算结果的对比分析,探讨外业像片控制点的布设方案对IMU/DGPS辅助航空摄影测量加密精度的影响,利用不同地形类别的加密数据,分析在保证成图精度的情况下如何减少外业工作量,降低生产成本,缩短生产周期。 更多还原

【Abstract】 The Leica ADS 80 Airborne Digital Sensor applied POS/GPS accurate navigation positioning technology for aerial photogrammetry.By the comparison and analysis on aerial triangulation results of traditional control points layout,fewer control points layout,and without control points for GPS differential data,this paper discussed the effects of layout plan of field photograph control points on the accuracy of aerial triangulation in IMU/DGPS assisted aerial photogrammetry.Using the triangulation dat...
