摘　　要：自由曲面测量路径的规划直接关系到曲面测量效率,现有的行测法测量区域设定和路径规划方法往往会产生一定的空行程而导致测量效率低下。采用简单多边形精确描述不规则测量区域形状,并在分析多边形凹点周边区域特征的基础上对多边形进行剖分,将多边形剖分为一组凸多边形和单调多边形,所产生的子多边形可以直接进行行测法测量路径而不会产生空行程,从而提高整个区域的测量效率。最后,通过对比实验,证明了该方法是有效的。The route planning for measuring free form surface concerns the measuring efficiency,while the current ways of route planning often bring idle measuring route and lead to low efficiency in measurement.This paper provides a way to describe the boundary of irregular region with polygons precisely,decomposing the irregular region into simple components based on character of the neighborhood around the concave points.These sub polygons can be route planned without idle measuring routes,and the efficiency of measuring the whole region is improved.The way is proved by experiment.
