Abstract

The invention discloses a different resolution infrared and visible light image fusion method and system based on total variation, which comprises establishing a total variation model of image fusion,respectively constraining the fusion image and the infrared image with a data fidelity term and a regularization term, and fusing the relationship between the image and the visible light image, according to the source image, solving the optimal solution of the total variational model and obtaining the fusion result. The invention builds a model according to the situation that the original infrared image and the visible image have different resolutions, and the obtained fusion image has high resolution and clear texture details, while retaining the characteristic that the pixel intensity distribution of the infrared image protrudes out of the thermal target, and the fusion result is convenient for human eyes to discriminate the thermal target and has good visual effect.

Description

Technical field [0001] The present invention relates to the technical field of image fusion. Specifically, the present invention relates to a technical scheme for fusion of different-resolution infrared and visible light images based on a total variation model. Background technique [0002] The basic goal of image fusion is to combine images obtained by different sensors to generate information images that are helpful for subsequent processing or decision making. Among them, the combination of infrared and visible light can present the inherent properties of almost all objects. Infrared images are imaged by reflected thermal radiation. They are not affected by ambient light and can overcome obstacles to find targets. However, due to the limitations of hardware equipment and application environment, infrared images are often accompanied by problems such as low resolution, large noise, and blurred details. The resolution of infrared images is costly and difficult; visible light im...
