A method and system for fusing infrared light image and visible light image, The method comprises the following steps: processing infrared light image and visible light image to be processed respectively by using Laplace operator to obtain high-frequency information image and low-frequency information image of infrared light image and high-frequency information image and low-frequency informationimage of visible light image; Fusing a high-frequency information image of an infrared light image and a high-frequency information image of a visible light image according to a first preset strategy;Fusing a low-frequency information image of an infrared image and a low-frequency information image of a visible image according to a second preset strategy; fusing The fused high-frequency information image and the fused low-frequency information image to obtain the fused image. The method and system for fusing infrared light image and visible light image realize the fusion of infrared light image and visible light image, and the fused image can maintain good contrast.
Description
technical field [0001] The invention relates to the technical field of image processing, in particular to a fusion method and system for an infrared light image and a visible light image. Background technique [0002] In some application fields, such as the field of individual combat reconnaissance or security monitoring, the demand for image information is increasing. Correspondingly, multi-image sensing and fusion technology has begun to be respected, that is, the same device can obtain different bands. For light image sensors, the images acquired by different sensors contain different feature information, which brings more convenience. For example, in reconnaissance equipment, infrared light imaging is more suitable for finding targets, and visible light images are more suitable for identifying targets. In the reconnaissance, the fusion of infrared light images and visible light images can make it easier to "discover" targets and "identify" targets. [0003] In the prior...
