Real-Time SAR Image Registration Based On Segmentation Of Distorted Image

Due to atmospheric interference, topographic fluctuation, unstable radar platform and other factors, SAR image geometric distortion, which is especially significant in the real-time SAR image of UAV, cannot be avoided. In order to solve the problem of SAR image geometric distortion, a registration method based on image segmentation is proposed. The algorithm classifies the image regions according to the degree of image distortion, calculates the mapping relation of different distortion regions, and finally completes the registration of the whole image by using image mosaic reconstruction.
