Abstract

The present invention relates to a method, device and computer storage medium for improving the radiation resolution of SAR images based on multi-angle images, characterized in that the method includes: preprocessing the multi-angle images based on SAR images, the preprocessing at least Including unified quantization processing and edge filling processing; using one of the multi-angle images as a base image to perform non-local mean filtering processing to obtain a reference image; performing joint non-local mean filtering on the reference image and the unprocessed multi-angle image process to obtain the reconstructed image of the image; use the reconstructed image as a new reference image to continue to perform joint non-local mean filter processing on the unprocessed multi-angle image until the preset condition is reached or all the multi-angle images are processed and the iteration ends, and the The final reconstructed image is used as the observation image of the target area. The invention can effectively improve the radiation resolution of the image, and at the same time better preserve the detail information in the image.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a multi-angle image-based SAR (Synthetic Aperture Radar) image radiation resolution improvement method, device and computer storage medium. Background technique [0002] Today, synthetic aperture radar has become one of the important means of earth observation due to its excellent characteristics such as all-weather, all-time, high precision and wide range, and is widely used in military and civilian fields. In SAR images, radiation resolution reflects its ability to distinguish the backscatter coefficients between targets, and is used to measure the image grayscale resolution. The level of image radiation resolution will affect the subsequent applications such as edge detection, segmentation and recognition of the image to a certain extent. Therefore, how to improve the radiometric resolution of SAR images is an important part of SAR image processing. [0003]...
