| 摘 要： | 在分析CMM测量数据特点的基础上，本文提出了基于多维分层的数据分层方法，利用了首尾判断法进行层内数据的排序，然后建立了大规模数据的拓扑关系。以此为前提，提出了距离阈值法和向量角度法相结合的数据精简算法。经实例验证，本算法是实用且有效的，为曲面重构奠定了技术基础。

| Abstract: | By analyzing the characteristics of CMM data measuring, the layering method for data based on multi-dimension is presented in this article. The method of beginning and end determination is used to rank the order of the data of inner layer, and then the topology relation between the large-scaled data is established. Under this premise, the algorithm of data simplification is offered which combines the method of distance threshold with the one of vector angle. The living example proves that this algorithm is practical and effective so that it can build up foundation for the reconstruction of curved surface. |
