摘　　要：MC颅面重构方法复原的面皮和颅骨三角片数量大且存在杂质。针对该问题,基于断层轮廓序列,利用改进的Snake模型提取闭合颅骨轮廓线,通过射线法对该轮廓线进行二次处理得到最外层轮廓线,从而实现颅面三维重构。实验结果表明,该方法在颅面数据量较小的情况下,可以准确表达人的面部和颅骨的形态信息。MC craniofacial reconstruction method recovers the face skin and skull triangles in large quantities and exists impurity. Aiming at this problem, this paper uses improved Snake model to extract closed skull contour lines based on fault contour sequence. Ray method is used to accurate extract outermost layer of the skull contour. Experimental results show that the method can generate method under the condition of small craniofacial data quantity, and it can express the facial and skull form information correctly.
