基于编织物常见的几种疵点为研究对象，利用改进的相角变换算法对编织物疵点进行特征提取，并在此基础上利用马氏距离对编织物二值化以实现疵点检测，利用几何数学原理实现对编织物疵点的分类。方法实现简单，相对于以往的编织物疵点检测，不仅使检测出的疵点形状大小更接近疵点原样，又能检测出不易察觉的小疵点，并且对于点、线、块状的疵点检测都有良好的效果，使得编织物疵点类型识别更加容易。
基于編織物常見的幾種疵點為研究對象，利用改進的相角變換算法對編織物疵點進行特徵提取，併在此基礎上利用馬氏距離對編織物二值化以實現疵點檢測，利用幾何數學原理實現對編織物疵點的分類。方法實現簡單，相對于以往的編織物疵點檢測，不僅使檢測齣的疵點形狀大小更接近疵點原樣，又能檢測齣不易察覺的小疵點，併且對于點、線、塊狀的疵點檢測都有良好的效果，使得編織物疵點類型識彆更加容易。

By studying several common knit defects, improved phase angle transform algorithm for knit defects feature extraction and the Mahalanobis distance for knit binarization to achieve defect detection are used in this method. Mathe-matical principles to achieve knit defect classification are used. This method not only can detect subtle small defects, points of defects, lines of defects, blocks of defects, but also the shape and size of defects is as closer as original kint defects compared with the previous knit defect detection.
