几何变换的误差传播

Error Propagation of Geometric Transforms

采用最坏情况法研究几何变换中的误差传播问题 在给出基本几何元素误差域表示方法的基础上 ,讨论对称、旋转变换的误差传播规律 ;并利用Minkowski算子 ,给出计算几何变换后误差域的算法 。

Error propagation of geometric transform with worst case approach is presented Following the representation of tolerance zones of basic geometric elements, the rules of error propagation of mirror symmetry and rotation are formulated We also present the algorithms of computing the tolerance zones of theses two geometric transforms with Minkowski, which provides the basis for the further study of geometric tolerance control
