自由曲面测量的区域划分准则研究

Study on Planning for Measuring the Sculpture Surface

数据测量是反求工程CAD建模的首要工作,当被测对象为自由曲面时,对曲面进行合理的区域划分可保证准确全面地获取实物表面数据。曲面测量区域划分是否合理将直接影响曲面的拼接质量和曲面整体品质,在目前应用广泛的三坐标测量机曲面测量中,测量区域划分应遵循四条基本准则。

Measuring is the first work in the reverse engineering CAD modeling. If the measured object has a sculpture surface a suitable planning of the surface will acquire coordinate exactly and perfectly. If planning of surface measuring is suitable the surface merging and all of the surface will be finished finely. For the measuring with three-coordinate CMM which is widely used four base rules are given.
