Manufacturing method of 3D printing pelvis

The invention relates to the technical field of medical assistance and particularly relates to a 3D printing pelvis manufacturing method. The method comprises the following steps of S1, acquiring a pelvis image of a patient; S2, excavating a pelvic skeleton in the pelvic image based on a Faster RCNN model; S3, based on the Faster RCNN model, delineating an area where soft tissue on the pelvic skeleton is located, and generating a soft tissue image; S4, realizing three-dimensional reconstruction of the pelvic skeleton and the soft tissue to obtain a pelvic skeleton three-dimensional model and asoft tissue three-dimensional model; S5, based on the positioning information of the soft tissue on the pelvis skeleton, soft tissue three-dimensional model areas carried in the pelvis skeleton three-dimensional model being removed one by one, after removing being completed, repairing processing of the three-dimensional model being conducted, and a pelvis 3D model being obtained; and S6, realizing pelvis printing through
