Abstract

The invention discloses a method and system for fusion of infrared and visible light images with different resolutions based on total variation, including establishing a total variation model for image fusion, using data fidelity items and regularization items to constrain the fusion image and infrared image respectively , The relationship between the fusion image and the visible light image; According to the source image, the optimal solution of the constructed total variation model is solved to obtain the image fusion result. The present invention models the situation where the resolutions of the original infrared image and the visible light image are different, and the obtained fusion image has high resolution and clear texture details, and at the same time retains the characteristic that the infrared image uses pixel intensity distribution to protrude the thermal target, and the fusion result is convenient for human eyes The discrimination of hot targets has good visual effects.

Description

technical field [0001] The present invention relates to the technical field of image fusion, in particular, the present invention relates to a technical scheme of infrared and visible light image fusion with different resolutions 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 informative images that facilitate subsequent processing or assist in decision-making. Among them, the combination of infrared and visible light can present the inherent properties of almost all objects. Infrared images are imaged through reflected thermal radiation, not affected by ambient light, and can overcome obstacles to find targets. However, due to the limitations of hardware equipment and application environments, infrared images are often accompanied by problems such as low resolution, large noise, and blurred details. The resolution of infrared images is expensive and difficult; vis...
