| 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. |
