摘　　要：本文对高精度轻小型航空遥感系统地对地检校场试验进行了分析,详细介绍集成系统检校原理,简要给出外业实验情况以及内业数据处理的过程,重点给出利用POS获取姿态转换得到的影像外方位元素即直接地理定位、单片后交方法获取外方位元素以及直接利用控制点绝对定向,均匀采集检校场外业检查点,进行精度验证的比较结果。最终实现塔吊模拟飞行条件下高精度的直接地理定位。The analysis in calibration field of light-small aerial remote sensing system was given in this paper. A detailed analysis on the principle of integrated system was addressed and a brief introduction of field test process and data processing was presented. Three different methods including DG, single image backward intersection, absolute orientation directly using control points were used to well-distributed collect the control points in the calibration field, and verity the accuracy of direct georeferencing. Finally, the high accuracy of direct georeferencing based on the environment of flight simulator tower crane was realized.
