摘　　要：本文介绍了一种基于特征的纱线气圈图像边缘提取方法,利用纱线气圈图像的特点,采用近轴法找到一些边缘点,利用这些点信息,用正交函数作最小二乘法拟合,去判断其他的点是否为边缘点,然后由边缘点拟合纱线气圈图像边缘,实验证明该方法是有效。The paper introduced a kind of method of extracting edge of yarn atmosphere based on feature, and make use of the near axes method, adoption feature of image of yarn atmosphere to find out some points, and make use of these points’ information to match to judge the other point if order for edge, to use method of orthogonal function of least squares. And then edge points are collected to intend to resemble the edge of the yarn atmosphere, experiment proof that method validity.

关 键 词：边缘提取 正交函数 最小二乘法拟合
