This invention discloses a method for intraoperative navigation of craniostomy based on curvature guidance and online pose maintenance, belonging to the field of intraoperative navigation of craniostomy. This invention constrains the curvature prior of the natural human structure: curvature estimation uses the auricle (along the arcuate ridge line of the helix / antihelix) and the nasal ala (along the arcuate ridge line of the nasal ala rim / nasal groove) as anatomical references, preferentially preserving these curvature features and suppressing their tangential "sawtooth" jitter; it provides a continuous and stable 6DoF initial pose on the time axis, and gating freeze / backoff is used to avoid initial value jumps in case of occlusion or mismatch; spatially, curvature-guided filtering is used, combined with anisotropic diffusion of prior constraints to complete edges and holes, improving effective overlap and connectivity. The correspondence between point clouds is more reliable, and the initial values ​​are closer to the true solution, thus enabling robust kernel ICP to converge stably under normal / distance gating, meeting the requirements of high-precision rigid registration and continuous navigation of intraoperative-preoperative 3D models.
