摘要
曲面内腔类零件的反求有别于轮廓外形的反求,主要体现在数据采集的方法,点云的处理,特征点的提取以及曲线的拟合。本文将以内腔类零件柴油机气缸盖的气道为载体,讨论几何特征异面的曲面内腔类零件的反求。
The reverse of lumen part is different from outline,such as collect data method,treat with point,pick up feature point and curve fitting.This passage is based on lumen part of diesel engine Cylinder Head＇ s airway,discuss about the method of the reverse of different face of lumen part.
