Fabric Defect Detection Method Based on Image Distance Difference LU Yun1,2，ZHANG Jing-miao3，JIANG Jian-wei1  1．College of Information and Technology, Hebei University of Economics and Business，Shijiazhuang，050061； 2．College of Information science and engineering, Hebei University of Science and Technology, Shijiazhuang, 050054； 3．Computer Center, Hebei University of Economics and Business, Shijiazhuang, 050061) Abstract: By using machine vision and digital image processing technology to fabric defect detection, this paper brings forward a new method of detection of fabric defect, namely image distance difference arithmetic. The arithmetic permit user to set appropriate control parameter of fabric defect defection based on the type of the fabric. It can detect more than 30 kinds of common defects, and by experiments proved it has advantages of high identification correctness and fast inspection speed.
