Abstract

The embodiment of the invention provides an image fusion method and device, an electronic device and a computer readable storage medium. The method comprises the following steps: firstly, obtaining each frame of image obtained through at least two times of exposure in an image collection period; determining an infrared brightness sensing image on the basis of one frame of each collected frame of image; determining a visible light color image based on the rest images in each frame of collected image; and finally, fusing the determined infrared brightness sensing image and the visible light color image to obtain a fused image. According to the scheme provided by the embodiment of the invention, each frame of image obtained through at least two times of exposure in an image acquisition periodcan be acquired by an image sensor. Therefore, as long as one image sensor exists in the device, image collection and fusion can be completed to improve the image quality under the condition of low illumination, so that the device provided by the embodiment of the invention is good in adaptability and convenient to apply.

Description

technical field [0001] The invention relates to the technical field of image acquisition, in particular to an image fusion method, device, electronic equipment and computer-readable storage medium. Background technique [0002] Fusion in image fusion technology can be understood as: fusing visible light images with infrared images and other non-visible light images to obtain a fused image; where the fused image is a dual-band image, compared to a single-band visible light image and non-visible light image For any image in the visible light image, the fused image can reflect more image information. [0003] In the prior art, image fusion technology mainly refers to spectroscopic fusion technology. The basic process of image fusion in this technology is as follows: the incident light is divided into visible light signal and invisible light signal by a spectroscopic device such as a spectroscopic prism, and then the two sensors are respectively based on the visible light signal...
