ISO根据最小区域的概念定义了形状误差，但没有描述获得最小区域的方法。本文讨论了现有方法的不足，提出了一种新的算法。该算法能保证给出最小的形状误差值。该算法非常适合在可与三坐标测量机连接的计算机上实现。
ISO defines form error based on the concept of minimum zone, but does not describe the methods to obtain the same. In this paper, drawbacks of the available methods are discussed and a new algorithm is presented. This algorithm is guaranteed to give the minimum value of form error. The algorithm is well-suited for implementation on a computer which may be interfaced with a Coordinate Measuring Machine.
