摘要
人体的形状比较复杂,存在多个分支,从扫描得到的序列轮廓线重构人体表面会存在空洞。通过定义场函数将一系列平面上的多条轮廓线转换为体数据,并采用Marching Cubes方法抽取等值面,将多轮廓线间的形体重构转化为体数据中的等值面构造。采用该方法重建的人体表面完整,光滑且符合精度要求。
The human body shape is very complicated. The surface reconstructed of two-dimensional sequence contours acquired by scanning exist holes if reconstructed directly. Contours were converted into volume data by defining field function and then the isosurface was extracted by marching cubes method. So the reconstruction of multi-contours was transformed into the reconstruction of volume data. Appling it into the reconstruction, more integrity, smooth and accurate surface of human body can be got.
