| 摘 要： | 将三维空间面皮转换为二维平面可以使获取面皮特征、颅骨与面皮的关联信息更方便。通过改进的轮廓线提取方法剔除原始切片冗余数据，对重构得到的面皮数据进行空间坐标系的规范，并以最近邻区域(NNR)划分方法将空间面皮的点云数据点集化，最后结合新划分的平面点数据集的特点提出了线性插补的参数平面化方法和基于链表的参数平面化方法。实验证明两种方法的效果良好，验证了其正确性和可行性。

| Abstract: | Three-dimensional space face into two-dimensional plane to obtaining face features,information between skull and face is good efforts.This paper improved extraction methods to contour the raw data to remove redundant data,reconstruct and adjust face spaces coordinate system,coordinating of the point cloud data after unification select a set of nearest neighbor region divided methods.According to characteristics of data plane,gave a linear interpolation parametric plane method and a based list parametric plane method.The experiment proves that two methods have good effects,and proves its accuracy and the feasibility. |
