    • Coordinate measurement data such as point cloud data associated with coordinate measurement machine data is reduced in a strategic and systematic manner by segmenting and/or reducing data based on nominal geometric information contained in an electronic file such as a CAD model or a coordinate measurement machine inspection plan. For example, in one embodiment, a software application is used to identify geometric features and tolerances within a CAD model of an object, and to segment coordinate measurement data of a physical object based on the identified geometric features and tolerances from the CAD model. The various segments of coordinate measurement data may be assigned different data requirements, and the data may be reduced in different manners on a feature-by-feature basis.
    • 通过基于包含在诸如CAD模型或坐标测量机检查的电子文件中的标称几何信息来分割和/或减少数据,以战略和系统的方式减少诸如与坐标测量机数据相关联的点云数据的坐标测量数据 计划。 例如,在一个实施例中,使用软件应用来识别对象的CAD模型内的几何特征和公差,并且基于来自CAD模型的所识别的几何特征和公差来划分物理对象的坐标测量数据。 坐标测量数据的各个部分可以被分配不同的数据要求,并且可以在逐个特征的基础上以不同的方式减少数据。
