摘要
通过对两平行直线包容测量数据点的分析,得到了两平行直线具有最小距离时必经过凸多边形的3个顶点的条件。根据上述条件,提出了基于凸多边形的直线度误差评定的方法,该方法满足最小包容区域。为求解直线度误差,采用矢量积构造凸多边形。通过实例验证了该方法的正确性和有效性。
The condition of the least distance between two parallel straight lanes passing mrougn mree vertexes on, the convex polygon is obtained by analyzing the enveloping measured data points. A method for evaluation of straightness error is presented based on the above condition in this paper, which meets the requirement of the minimum zone condition. The convex polygon is constructed by vector product in order to solve the straightness error. The method is implemented and validated with the data available in the literature.
