Ship remote monitoring video efficient transmission method based on image feature matching

The invention relates to the field of monitoring video compression transmission, in particular to a ship remote monitoring video efficient transmission method based on image feature matching. The method comprises the following steps: firstly, extracting key points and corresponding feature descriptors in each frame of grayscale image of a ship monitoring video, matching the key points of all the grayscale images to obtain a plurality of matching point sequences and feature points in the grayscale images, and combining a single frame of grayscale image and a plurality of frames of grayscale images to obtain a plurality of matching point sequences and feature points in the grayscale images; structural features and local information features of feature points in a preset neighborhood range are analyzed, the feature points in each frame of gray image are clustered through the obtained neighborhood change degree, a region of interest of each frame of gray image is obtained, the region of interest and a non-region
