UAVRS (unmanned aerial vehicles remote sensing) is widely used in various fields such as resource exploration, disaster monitoring. The paper designed a geometric distortion correction algorithm of UAV low altitude remote sensing image for emergency disaster, which mainly consisted of the following steps: eliminating rotational error, extracting the control points effectively and correcting geometric distortion for overlapping regions. Based on comprehensive experiments and applications, the algorithm is proved effectively to reduce the UAV image distortion. Furthermore, the algorithm can also improve the processing quality and reduce the processing speed of the image in emergency disaster situations.
