Abstract

The invention discloses an image stabilization-based remote sensing video satellite image processing method and system, and the method comprises the steps: carrying out the cataloguing processing of each frame, extracting the imaging time of each frame, enabling the imaging time of each frame to serve as a part of an image name, and enabling a plurality of image frames to form an image frame sequence group according to the time sequence; performing relative radiation correction on each frame of the sequence group to eliminate atmospheric radiation; after radiation correction, performing systemgeometric correction on each frame of the sequence group to eliminate geometric distortion generated in the frame during imaging; Taking the previous frame as a reference frame, and carrying out image stabilization processing on each current frame except the first frame in the sequence group, including motion estimation, motion compensation and image correction; and combining the image frame sequences subjected to image stabilization processing to form a video. In the processing process of the remote sensing video satellite, the imaging characteristics of a general remote sensing satellite and a video satellite are considered, and the processing process obviously improves the quality of the remote sensing video.

Description

technical field [0001] The invention belongs to the technical field of satellite remote sensing and video applications, and in particular relates to a remote sensing video satellite image processing method and system based on image stabilization. Background technique [0002] With the rapid development and diversification of satellite application fields, the development of remote sensing video satellites is also increasing rapidly. Generally, remote sensing image errors mainly include the following aspects: system error, that is, the error of the sensor itself; the influence of atmospheric scattering; the influence of lighting conditions. [0003] Taking the remote sensing video satellite with CMOS camera as the research object, the remote sensing video processing method based on image stabilization is explained. For the area array "staring" video, the difference in the value of the outer orientation elements of each frame of the video is the main reason for the motion betw...
