Abstract

The embodiment of the invention provides an image fusion method and device. The method comprises the following steps: acquiring a visible light image and an infrared image of a target image; respectively carrying out pixel filling on the visible light image and the infrared image to obtain a first visible light image and a first infrared image; sequentially performing brightness fusion and detail layer fusion on the first visible light image and the first infrared image according to a preset fusion rule to obtain a target brightness value and a target chromatic value of each pixel point in the target image; and obtaining a fused image according to the target brightness value and the target chromatic value of each pixel point. The embodiment of the invention solves the problems that in the prior art, an infrared image and visible light image fusion method is generally large in calculation amount and single in use scene.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to an image fusion method and device. Background technique [0002] With the rapid development of Internet technology, video surveillance system has entered various fields of work and life, and plays an important role in many fields; video surveillance system mainly contributes to its application fields based on the pictures it takes. The clarity of the picture is of great significance to the video surveillance system. [0003] When the camera takes pictures, it is highly dependent on the light. Therefore, the effect of taking pictures at night is usually poor and the definition is low; in order to solve this problem, at night or in other scenes with low ambient brightness, in order to obtain good To monitor the image quality, it often needs to be irradiated with visible light with high energy density. However, the supplementary light is more irritating to human eyes, and it ...
