Abstract

The invention discloses a fusion method of an infrared image and a visible light dynamic image and a fusion device of the infrared image and the visible light dynamic image and belongs to the image processing field. The image fusion method comprises calculating an image registration parameter; collecting the infrared image and the visible light image respectively and carrying out image registration to the infrared image and the visible light image according to the image registration parameter; and carrying out image fusion to the infrared image and the visible light image after the image registration are carried out to the infrared image and the visible light image. Due to the fact that in a image fusion process of the infrared image and the visible light image, the image registration is achieved according to the image registration parameter, the calculated amount of numerical value change is decreased greatly, calculating speed is improved, and further speed of the image fusion is improved, and real-time requirements of image processing are met.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a fusion method and device for infrared and visible light dynamic images. Background technique [0002] Due to the various limitations of the image sensor's own physical characteristics, imaging mechanism, and viewing angle, a single image sensor is often unable to extract enough information from the scene, so that it is difficult or even impossible to obtain a comprehensive description of a scene independently. In order to meet the needs in practice and make full use of the image information of multiple sensors, various image fusion techniques have developed rapidly. [0003] The visible light image is a reflection image with many high-frequency components, which can reflect the details of the scene under a certain illumination, but the contrast of the visible light image is low when the illumination is not good; the infrared image is a radiation image, and the grayscale is deter...
