A bone registration method and system for joint replacement surgery, based on a VSF surface in a preoperative coordinate system generated from preoperative bone image data and a source point set SPS in an intraoperative coordinate system generated from point data collected from the patient's actual bone surface during surgery, determines the transformation relationship between the preoperative and intraoperative coordinate systems through initial and precise registration. The method includes: a first step: selecting multiple corresponding point pairs from the source point set SPS and the VSF surface, performing initial registration based on Singular Value Decomposition (SVD), and obtaining the initial transformation matrix; and a second step: performing precise registration based on the initial transformation matrix using the ICP method. Each ICP iteration employs a least-squares optimization method that minimizes the sum of squared distances between each point in the transformed source point set SPS and the corresponding projection points in the projection point set PSPS. The algorithm stops when the error is less than a set value or the number of iterations reaches a set value.
