Embodiment Construction
[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.
[0027] The invention is a defect detection method of patterned cloth. The detection process is divided into an offline training process and an online detection process. The installation method of the smart camera is as follows: figure 1 As shown, the overall flow chart of the algorithm is as follows figure 2 shown. In the process of offline training, the first layer of fuzzy classifier is established through accurate cycle calculation, construction of standard flawless primitive offset sequence, and feature extraction. In the online process, analyze the difference between the image block to be detected and the standard unblemished primitive offset sequence to extract energy and variance features. First, use the first-le...
