Direct difference is sensitive to noisy data, so a threshold limitation is given, which can not only filter the result from noisy data but also pick edge points up according men's desire. On the other hand, artificial intelligence is used for segmentation in reverse engineering. Because the essence of segmentation is clustering similar characteristics and self-organizing feature mapping is one function of neural network, SOFM network is used for segmentation in the thesis, coordinates and normal of data points is took as the characteristics vector.
第二种方法,基于双向角度微分的边点提取法,针对三维正交模型采用基于截面线的方式组织数据,此方法比基于曲率半径方法更简洁,不用进行曲面拟合,大大提高了计算速度;计算过程中由数据点的直接差分逼近微分,但直接差分对数据误差敏感,为此,本文提出了阈值过滤的方法,一方面过滤了数据误差在计算结果中引起的噪音,另一方面可以按照设计意图控制边点的提取;来决定是否提取光滑交接的边点。

Plyfil composite yarns is similar to two-ply yarn structures.
纺纱方法决定着成纱结构,成纱结构与纱线组成原料又决定了纱线的性能。sirofil复合纱线纺纱时长丝与短纤纱须条的间距及长丝的张力,plyfil复合线加工时二组分间并线张力对成纱结构及纱线的性能有着重要影响。sirofil复合纱的成纱横截面呈近似圆形结构,长丝位于成纱的一侧;纵向呈有"股线螺纹"的单纱外观。plyfil复合线具有类似于传统双股线的横截面和纵向外观。
