Fusion method and device for two camera images and equipment

The invention discloses a fusion method for two camera images. The method comprises the steps that first brightness information and color information of a target color image in a predetermined formatand second brightness information of a black-white image are extracted; and the first brightness information and the second brightness information are fused with the color information after being fused, and an image obtained after fusion is converted into a fusion image in an RGB format. Obviously, according to the scheme, during fusion of the two camera images, the brightness information of the color image and the brightness information of the black-white image are fused, and the brightness information obtained after fusion and the color information are fused to generate the final image; andwhen the mode is applied to an endoscope system, the problems of low image brightness, a dark distant view, a small image dynamic range, fuzzy details and the like of the endoscope system can be solved, and the definition of t
