The disclosed method includes acquiring sample models and marking sample feature points; selecting target feature points and regional points on bones; transforming the target feature points and the regional points, and registering the target feature points with the sample feature points; formulating a strategy for assigning impact factors to the sample models, linearly combining all sample models to construct an initial model, and determining initial feature points corresponding to the target feature points in the initial model; adjusting the strategy according to the distance between initial feature points and the target feature points, selecting the strategy corresponding to the minimum distance as an optimal strategy, and determining an optimal initial model; determining a matching point corresponding to each regional point in the optimal initial model, and calculating a transformation relationship; and transmitting all points of the optimal initial model according to the transformation relationship to obtain a target bone model.
