摘　　要：随着计算机辅助设计技术的不断发展,三维参数化设计作为一种新的计算机辅助设计方法已经得到广泛应用。提出应用投影栅相位法测量人体的三维数据,在最小二乘意义下采用B样条拟合曲面的方法,在临床治疗和医学基础研究方面有重要的实用价值。With the developing of the technology of Computer Aided Design, three-dimensional （3 D） parametric design, as a new computer aided design method, had been widely used. The system was based on the Phase Detection of Projected grating to sense body＇ s 3D data, surface fitting was simulated by B-spine patches in the sense of piecewise least square, so it had more practical value in treatment and basic medical study.
