AI Technical Summary
Technical Problem
When an endoscope collects images in a narrow cavity, due to the fixed focal length of the lens, some areas are clear and some areas are blurred, resulting in poor image fusion effect in the existing technology.
Method used
By screening historical key frame images based on lens depth, obtaining a reference frame set and a historical key frame set, determining the target depth range, and performing image processing to fuse clear areas, the image fusion effect is improved.
Benefits of technology
The blurred area in the fused image is reduced, the image fusion effect is improved, and more complete information is provided.

Abstract
The application provides an endoscope image processing method, device and equipment and an endoscope system, relates to the technical field of endoscope image processing, and the method comprises the following steps: acquiring a current frame image, a reference frame set and a historical key frame set; screening the historical key frame set according to a target depth interval corresponding to the current frame image; obtaining a to-be-processed frame image capable of providing clear information for a blurred area of the current frame image; and performing image processing based on the reference frame set and the to-be-processed frame image to obtain a target frame image. The historical key frame image is screened based on the lens depth, the to-be-processed frame image capable of providing a clear area for the blurred area of the current frame image is screened, complete information is provided for image fusion, the blurred area in the target frame image obtained through fusion can be reduced, and the image fusion effect can be improved.
