Abstract The composition of the low-altitude unmanned aerial system is described, and then the single image correction method,the after stitching correction method and the aerial triangulation method of mapping by using the UAV images are proposed according to their small scene and high resolution of the UAV images. The key points of the three different mapping methods are emphatically discussed, and the three methods are jointly analyzed and tested according to their mapping effect, accuracy and efficiency. The results demonstrate that the after stitching correction method has higher efficiency, and the aerial triangulation method has better accuracy, with the single image correction method in between, as evidenced by judging the efficiency and accuracy.
