Human body three-dimensional curved surface modeling method based on 3D vision

The invention discloses a human body three-dimensional curved surface modeling method based on 3D vision. According to the technical scheme, the human body three-dimensional curved surface modeling method is characterized by comprising the steps that S1, depth data are obtained through a depth camera; s2, converting the depth data into point cloud data, and preprocessing the point cloud data to obtain a human body point cloud result; s3, generating an embedded deformation model according to the human body point cloud result; s4, carrying out local segmentation on the whole sequence according to a human body structure; s5, registering each segmented local part by adopting a non-rigid registration algorithm; s6, aligning each segmentation part by adopting a global optimization method, and carrying out secondary processing; and S7, a complete human body point cloud is obtained, a human body three-dimensional curved surface model is achieved through Poisson surface reconstruction, human body three-dimensional cur
