| 摘 要： | 针对带有精确截面信息的有序离散点的三维曲面重构问题，提出了一种NURBS曲面快速重构方法。该方法有效地减少了运算数据量，提高了运算效率，同时改进了传统曲面拟合在处理非均匀截面数据点时曲线曲面形状的失真和运算的不稳定现象，最后应用三维图形标准以及图形函数库在实际系统中验证了该方法的有效性。

| Abstract: | Aim for the 3D surface reconstruction with scattered data points in order of precise section, a rapid surface reconstruction method based on NURBS is proposed. This method can effectively reduce the amount of operation data and raise efficiency. It overcomes the weakness that surface shape loses the true and calculation is unsteady when traditional methods of surface reconstruction is dealing with non uniform 3 D scanned data points. By applying 3D graphic standard and library OpenGL, above algorithm has been accomplished and verified in practical system. |
