摘要
针对目前在曲线拟合中常用拐点提取法的弊端,提出一种新的拐点提取方法。其步骤包括:检测物体边缘轮廓;拟合边缘轮廓的分段直线;初步确定图像轮廓的拐点,并对所拟合的直线段进行线段合并,由此减少拐点的个数。
Aiming at the disadvantages of the commonly used methods of inflexion extracting, a new method of inflexion extracting based on the existing methods is put forward. Its process includes： detecting the edge figure of object; matching the subsection beeline of edge figure; ascertaining the inflexion of image profile at first; combing the subsection of beelines matched; and reducing inflections.
