Osteotomy line determination method, device, equipment and medium

The invention provides an osteotomy line determination method and device, equipment and a medium, the method is applied to the technical field of medical images, and the method comprises the following steps: obtaining a head image of a target object; segmenting the head image to obtain an upper jawbone image corresponding to the upper jawbone of the target object and a lower jawbone image corresponding to the lower jawbone of the target object; determining an upper jaw key point of the upper jaw bone based on preset key point labeling information and an upper jaw bone image, and determining a lower jaw key point of the lower jaw bone based on the key point labeling information and a lower jaw bone image; and based on a preset path algorithm and constraint information, performing path planning on the maxillary key point and the mandibular key point, and generating a maxillary osteotomy line and a mandibular osteotomy line of the target object. According to the method, the osteotomy line determination precision
