摘要：We propose a 3D head modeling method and a prototype of the facial surgery simulation system for surgicalprediction using a physics-based head model. The arbitrary head model is reconstructed to match the target headshape by the use of anatomical measurement points plotted on the two directional X-ray images from both offrontal and side views. The accurate 3D coordinates of their points are obtained using 3D CephalogramMeasurement. For the detailed fitting of the face, the feature points automatically detected from a frontal facialimage are utilized to match the facial parts such as eyes, a nose, and a mouth. These measurement points areemplogal as the control points in the model fitting process, and the other points are deformed by the smoothinterpolation based on their positions relative to the control points.In this paper, we focus on the facial surgery simulation, Orthodontic surgery. In the experiment, we predicted thefacial shape after surgery for patients with mandibular prognathism. We also simulate facial dynamics before andafter surgery, which is derived from both of muscular and skeletal systems. By comparing simulation results withthe actual facial images after surgery, proposed method can be proved to be practically useful
