An Image Measuring Method for the Fabric Defect Detection System

In order to realize fast measurement of fabric defect dimensions, an image measuring method is presented for the fabric defect detection system. Based on the image measuring theory, a suitable structure of the system hardware is constructed by using common device used in the fabric defect detection system. A new CCD calibration method based on grid targets is applied to the system. The experimental results show that the method is effective, high accuracy and easy to implement.
