摘　　要：为了提高坐标测量信息的获取效率并保证信息的完备性,引入多色集合理论,探讨了一种全三维环境下的测量信息表示及获取机制。通过分析全三维环境下测量信息构成及特点,建立测量信息多色集合层次结构模型。依据该模型,建立测量信息获取推理关系矩阵,用于确定每个待测公差项目的公差类型、与之相关的几何要素、以及对应的几何参数。根据测量信息获取流程,基于UG NX系统,定制了信息获取工具,并通过实例验证了基于多色集合进行测量信息表示与获取的可行性。Aimed to obtain higher efficiency of measuring information extraction and complete information,using Polychromatic Sets(PS),measuring information representation and extraction mechanism in 3D environment is discussed.Through analyzing 3D measuring information and its constitution,PS based measuring information hierarchical structure model is constructed.According to the model,reasoning matrix for measuring information extraction is presented so that measuring information including tolerance type,geometrical feature and related parameters can be extracted.In line with the flow of measuring information extraction,information extraction tool is customized in UG NX system.Finally,an application proves the feasibility of PS-based measuring information representation and extraction.
