特高压输电线路工程无人机影像精度提升分析OA

At present,unmanned aerial vehicles(UAV)are widely used for image acquisition in environmental protection and water&soil conservation projects of UHV projects.However,the orthophoto images acquired by UAV lacks external control to correct,resulting in low accuracy of the generated orthophoto images.They can only be used as ordinary inspection images in the early stage and cannot be further used for environmental protection engineering and water and soil conservation engineering check.Based on the actual UHV project,the existing UAV data are studied and analyzed.And a set of methods and processes are proposed to improve the accuracy of orthographic image,so as to better provide data support for the follow-up environmental protection and water&soil conservation verification of UHV projects.
