摘要
基于CMM测量数据,针对鼠标数据的特点,进行了边界拟合、特征识别、分片重建、光滑拼接等技术的研究。利用三次B样条拟合边界曲线,利用微分几何方法进行曲面特征的识别与分割,利用拉伸及放样法进行曲面片重构,最后进行曲面片相交、剪裁、过渡完成最终的鼠标模型。
Based on CMM data,the some critical techniques has been researched： boundary fitting,characteristic identifying,surface patch reconstructing,smooth matching considering the feature of mouse data.By employing cubic B-spline curves to fit boundary curves,differential coefficient geometry method to do surface characteristic identifying and division,and pulling and molding methods to accomplish surface patch reconstruction,the mouse model is finally fulfilled through surface patch intersecting,cutting out and transition.
