Abstract: 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.
