Target area classification method and system of white light image and computer equipment

The invention provides a white light image-based target area classification method and system, and computer equipment. The method comprises the steps of obtaining an original white light image; inputting the original white light image into a pre-trained first region recognition model to generate a target region white light image; inputting the target area white light image into a pre-trained second conversion model to generate a target area NBI image; acquiring a corresponding blood vessel segmentation image based on the target area white light image and the target area NBI image; and inputting the target region NBI image and the blood vessel segmentation image into a pre-trained third classification model to generate a target region type. According to the target region classification method based on the white light image, the conversion of the white light image to the NBI image can be realized, and the recognition precision of target region classification can be correspondingly improved, so that the accuracy
