在此基础上,研究实现了平面轮廓切割、嵌套切割、环切加工刀具轨迹的规划与生成算法。 - This paper describes the conjunction relationship of the basic point of the flat surface outline on the parts and reveals the internal law of the intersections connecting with the typical curve ; the principle of the calculation and the characteristics on straight line to parabola basic points are illustrated
摘要介绍了平面轮廓零件各组成元素之间的连接关系，并揭示了典型曲线交接的内在规律，阐述了直线与抛物线交接点的计算原理和特点，总结归纳直线与抛物线连接的处理方法，以及自动淘汰无效基点的基本准则。 - 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。 - Without using a model whose topology is known for mesh fitting , the algorithm simplifies the 3d surface topology problem to 2d surface topology problem by projection . then the best 3d surface topology is deduced using the minimum summing of spans criterion based on the " minimum offset " criterion which is proposed in this paper to determining the points links between two adjacent contours . the custom software is designed for 3d rendering using opengl interface
为解决不平行轮廓的重建问题，本文用投影的方法把三维表面拓扑结构问题转化为二维表面拓扑结构问题；为确定平面轮廓间点的对应关系，本文提出基于最小偏移量准则的轮廓拼接算法并用跨段之和最小准则来确定轮廓拼接的起始点和最佳可接受的表面，从而确定三维表面的拓扑结构。
