The error compensation is introduced in the interpolation algorithm to increase the interpolation point's solution precision in the cutting direction of the parametric curved surface. The reasonable simplification of the computed result of the interpolation point's parameter value is carried in the operation process by focusing on the character that curvature of slow-varying parametric curved surface changed slowly and the feature that the scanned profile of translational scanned curved surface is parallel along the scanned line.

通过引入误差补偿值以提高参数曲面在走刀方向上插补点的计算精度，针对缓变参数曲面曲率缓变和平移扫描曲面扫描轮廓沿扫描线平行的特点在运算过程中对插补点参数值的计算结果进行合理简化。

In comparison with the FEM mesh idealization, the parametric surface representation is comprised of more accurate approximation and less unknown variables for the tire contour.

与有限元法的离散相比，参数曲面的描述能够更好的逼近轮胎复杂的轮廓曲面并且有较少的未知变量数目。

In theses methods, the contour paring is carried out with OR and AND operations.

在这些方法中，轮廓的对应采用 OR运算和 AND运算来确定。

In fact, this is a partition problem and we model it as an energy minimization of a Mumford-Shah function based minimal partition problem like active contour model.

事实上这是一个分割问题，如同主动轮廓模型，我们把它看成是基于最小分割问题的Munford-Shah函数的最小化。

Such edges may be barriers, more or less penetrable, which close one region off from another; or they may be seams, lines along which two regions are related and joined together.

这些边线元素，尽管可能不像道路一样占主导元素，但对许多人来说是重要组织特性，特别是它可以将广阔的区域连接在一起，正如在城市轮廓中水和墙。

The result of this research shows that the error percentage is 0.61% comparing between the scanned contour and the true contour of object.
