Rapid registration and fusion method for infrared and visible light images

Abstract

The invention discloses a quick registration and fusion method for infrared and visible light images, which comprises the following steps of: simultaneously acquiring images of a same scene by utilizing an infrared sensor and a visible light sensor, and solving a homography matrix converted between an infrared image plane coordinate system and a visible light image plane coordinate system by adopting singular value decomposition; taking the visible light image as a reference image, and obtaining an infrared image registered with the reference image through homography transformation; and carrying out image fusion on the reference image and the registered infrared image by adopting an adaptive weight pixel point superposition method. Aiming at fusion of infrared and visible light heterologous sensor images, advantage complementation is realized, and the problems that visible light image features are difficult to extract and register under the condition of weak visible light are solved; and meanwhile, on the basis of ensuring certain fusion precision, the image fusion speed is greatly improved, and the real-time problem in practical application is solved.

Description

technical field [0001] The invention relates to an image processing method, which is an image fusion based on fast image registration based on homography transformation and pixel point superposition based on adaptive weight, in particular to a fast registration and fusion method of infrared and visible light images. Background technique [0002] Image fusion is to fuse two or more images of the same scene according to a specific algorithm, so that the information contained in the fused single image is more comprehensive, and it is more suitable for human visual understanding and computer detection, classification, recognition and other tasks. At present, image fusion technology has been widely used in many fields, including remote sensing image analysis and processing, computer vision, unmanned driving, medical image processing, and target detection and tracking. Among them, in the field of target detection and tracking, visible light is mainly used. Visible light images can...

Problems solved by technology

Among them, in the field of target detection and tracking, visible light is mainly used. Visible light images can provide details and texture information of the target, but under the condition of low visibility, the working effect of visible light will be greatly affected; and the imaging mechanism of infrared is different from that of visible light imaging. , which can effectively image thermal targets under conditions of low visibility, but it is not sensitive to scene brightness changes, and the imaging resolution is low
