分段数据 meaning in Chinese

segment data

A method for complicated planar contour fitting is presented : 1 ) first all the data points used in the contour are ordered ; 2 ) after calculating the curvature of each contour point , the points with bigger curvature are taken as feature points ; 3 ) the contour is segmented by feature points ; 4 ) the contour is globally constructed through determining the segments types ( line or circle ) and the constraints with the neighbor segments ? the generation of skin surface is realized with the interface of caa
研究了基于点云数据的复杂截面线生成技术： 1 )对轮廓数据点进行排序； 2 )近似计算轮廓数据点处的曲率，取出曲率较大的数据点，并定义取出的数据点为特征点； 3 )以特征点为分界点对轮廓数据点进行分段： 4 )判断分段数据点确定的曲线类型和各分段曲线之间的约束关系，进行基于约束的分段平面轮廓曲线整体拟合。
