Multi-visual Detect System for Large-size LCD Glass Substrate
With the growing demand of Large-size LCD,quality inspection of Large-size LCD glass substrate has drawn more and more attention.We have developed a line scan imaging based Large-size LCD glass substrate multi-vision detection system to solve the problem of its quality inspection.Based on the system,we have designed the image processing algorithm which we first compute the Discrete Cosine Transform (DCT) and then distinguish defect from non-defect of the sub-windows by K-means cluster.Experiments show that our system is simple,fast in calculation and can meet the requirement of real-time detection of production line.
