Image processing method and device, electronic equipment and computer readable storage medium

The embodiment of the invention discloses an image processing method and device, electronic equipment and a computer readable storage medium. The method comprises the steps of obtaining CT image data; first segmentation processing is carried out on the CT image data to obtain a bone segmentation image, and image segmentation can be effectively carried out on a bone region with a relatively large contrast ratio between a CT pixel value and peripheral tissues through the first segmentation processing; second segmentation processing is carried out on the CT image data based on the cartilage segmentation model to obtain a cartilage segmentation image, and the second segmentation processing can effectively segment a cartilage region with the contrast close to that of peripheral tissues; and carrying out image fusion processing on the bone segmentation image and the cartilage segmentation image to obtain a target bone segmentation image, thereby solving the technical problem that in the bone segmentation of the CT image, the accuracy of the bone segmentation in the CT image is difficult to guarantee because the CT development of the cartilage and the CT development of the soft tissue are too close.
