摘要:
光顺的数据是鞋楦曲面建模的基础,必须对测量得到的含有噪音成分的原始数据进行识别和光顺处理.本文分析了尖点的分布规律,给出了基于曲率的尖点识别方法,并得到了两种求解曲率的方法.针对尖点识别过程中尖点阈值大小的确定问题,提出了一种自动调整的阈值确定方法,提高了算法的效率,同时有效的避免了尖点的漏判和多判问题.在尖点识别的基础上,对鞋楦数据尖点曲线和截面曲线分别进行了最小二乘和多点求均值的光顺处理,得到符合要求的光顺的鞋楦数据.
Abstract:
Data smoothing is the basis for the surface modeling of shoelast,and it is necessary to make the recognition and smoothing treatment of the initial data that is measured including noise points. This paper analyses the distribution rule of sharp points and recognition method of points based on curvature,at the same time two ways of calculating the curvature are obtained. Aiming at the determination problem of threshold value of points recognizing,a determination method of threshold value by autoconditioning is put forward,which improves the efficiency of algorithm and effectively avoids estimating mistakes. On the basis of points recognizing ,the points curve and the cross section curve are smoothed using least square and average value of multipoints.
