Accuracy Analysis of DJI Phantom4 RTK Orthophoto Based on Pix4Dmapper Software
Aiming at the accuracy analysis of UAV orthophoto, a precision analysis method of DJI Phantom4 RTK orthophoto based on Pix4Dmapper software is presented. Taking DJI Phantom4 RTK as an example, this method uses Pix4Dmapper software to solve the photo data of its flight, and compares the difference in plane accuracy and elevation accuracy of orthophoto generated by 3D oblique photography flight mode and 2D ortho flight mode for the same operation area. The influence of image control points on the accuracy of results is analyzed in low altitude flight mode. Experiments results show that Phantom4 RTK can meet the requirements of producing orthophoto and topographic map without image control in low altitude 2D orthophoto flight mode, which provides a new idea for the ac-curacy analysis of UAV orthophoto.
