Problems solved by technology

Optical images have high resolution, rich color information, and are easy to interpret; however, image quality is poor at night and under poor lighting conditions such as cloud cover
Radar has the advantages of all-day, all-weather, and strong penetration, but the quality of radar images is affected by the level of clutter, and the interpretability is relatively poor

Abstract

The invention provides a fusion method of heterogeneous remote sensing images, relates to the technical field of image processing, and aims to integrate respective advantages of an optical image and a radar image to generate a fused image. The method comprises the following steps: acquiring an optical image and a radar image; the optical image and the radar image are input into a homogeneous change image generation model to obtain a fused image, and the fused image comprises content features of the optical image and style form features of the radar image; wherein the homogeneous change image generation model is a model which learns to generate a to-be-iterated image sample based on an optical image sample and a radar image sample, and iterates the to-be-iterated image sample to generate a fused image sample. The patent of the invention is subsidized by the national key research and development plan 2021YFA0715201.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular, to a fusion method of heterogeneous remote sensing images. Background technique [0002] Remote sensing images include optical images and radar images, and refer to image data about ground objects, sea surfaces, etc. acquired by space-based or space-based imaging sensors. Optical images have high resolution, rich color information, and are easy to interpret; however, the image quality is poor in poor lighting conditions such as nighttime and cloud cover. Radar has the advantages of all-weather, all-weather, and strong penetrability, but the quality of radar images is affected by the clutter level, and the interpretability is relatively poor. [0003] How to achieve complementary advantages based on optical images and radar images, and obtain images that can ensure that the integrity of content information is not lost even under complex terrain conditions, an...
