【摘要】 本文对高精度轻小型航空遥感系统对地检校场试验进行了分析,详细介绍数据处理的过程,重点给出利用PosAV系统后处理软件PosPac输出的导航结果计算影像外方位元素与空三获取外方位元素的比较结果,并在1∶500成图比例尺下,采用3种不同方法均匀采集检校场外业点进行直接地理定位精度验证,对于大比例尺测图是可以实现的。更多还原

【Abstract】 The analysis of SWDC calibration field test equipped with POS was given in this paper.A brief introduction of data processing in each process was given,also the differences between the exterior orientation elements calculated from the navigation data provided by the PosAV system post-processing software Pospac 4.1 and aerial triangulation were mainly addressed.At the same time,based on the 1∶500 photogrammetric scale,three different methods were used to symmetrically collect the control points in the calibration field.The results verified the accuracy of direct georeferencing in large scale.更多还原
