SIFT algorithm is the feature matching method based on scale space,which specified direction parameter for each key point with rotational invariance,so it is adaptable for image tilt.The paper extracted the UAV image feature point with SIFT algorithm,coarsely matched images with Euclidean distance,and precisely matched through distance error.Based on the analysis of splicing errors,the optimal path method was proposed to reduce the error finally.
