Abstract

The invention discloses a visible light and infrared image fusion method based on gradient transfer. The method comprises the following steps of: respectively acquiring an infrared image matrix and a visible light image matrix; with the principle of preserving the brightness information of an infrared image and the texture information of a visible light image, converting an image fusion process into an optimized problem; and obtaining a fused image by solving the optimized problem. According to the fusion method provided by the invention, the visible light image and the infrared image can be effectively fused, the fused image information is more abundant, the gradient texture information of the visible light image can be fused, and the temperature information of scenery can be reflected.

Description

technical field [0001] The invention relates to a fusion algorithm of visible light and infrared images, in particular, the invention relates to a fusion method of visible light and infrared images based on gradient transfer. Background technique [0002] In the past fifty years, optical sensor technology has been developed rapidly. However, a single optical sensor cannot fully reflect the image features, and the multi-sensor data processing technology and image processing technology using different sensors is becoming a research hotspot. Among them, image fusion technology can form a more comprehensive, reliable and accurate description of scenes and targets on the basis of fully analyzing the characteristics of different sensor images and combining the advantages of different sensor images. [0003] Image processing and image fusion technology can effectively solve this problem. The infrared imaging system has strong anti-interference ability, good concealment performanc...
