摘要
针对传统无人机航测内外业流程复杂、工作效率低等问题,对比了天狼星免像控系统和Inpho系统的无人机遥感数据后处理流程,并对输出的DOM、DEM成果精度进行比较,取得了以下结论:(1)天狼星免像控系统比Inpho常规无人机航测系统具有外业免像控、无需内业刺点、高度自动化一键式处理等优点,大大提高了作业效率;(2)天狼星免像控系统和Inpho系统在处理1∶500无人机遥感影像数据时,均能满足1∶500航空摄影测量精度要求,而且天狼星免像控系统处理的数据精度优于Inpho系统的数据处理精度。其中天狼星航摄系统DOM、DEM中误差分别为0.043 1、0.084 3 m,Inpho系统DOM、DEM中误差分别为0.052 6、0.158 6 m。
Aiming at the problems of low efficiency and complex process of internal and external work of traditional UAV aerial,the comparison between the Sirius system of no image control point and Inpho system in UAV remote sensing data post-processing is made,and the results of DOM and DEM outputs are compared. The following conclusions are obtained that the Sirius system of no image control point than Inpho system has no image control points,internal industry does not need to join the control point,highly automated one-click processing and other advantages,the efficiency of the operation is greatly improved. The Sirius system of no image control point than Inpho system can meet the requirements of 1 ∶ 500 aerial photogrammetry precision when processing 1 ∶ 500 UAV remote sensing image data,and the precision of Sirius system of no image control point is better than that of Inpho system. The errors of DOM and DEM in the production of Sirius air system were 0. 043 1 m and 0. 084 3 m respectively,the errors of DOM and DEM in the production of Inpho system were 0.052 6 m and 0.158 6 m respectively.
