TWO-DIMENSION CODE RECOGNITION BASED ON MACHINE VISION
According to components detection of the auto parts supply chain,put forward a kind code recognition method for DataMatrix code,PDF41 7 code,and QR code based on machine vision.The method of obtaining image firstly,and then using the image denoising technique to the image acquired with a 2D code processing,and then select different processing methods according to the 2D code can effectively identify these three 2D codes.The experimental result shows that the proposed approach is feasible and effective and can recognize DataMatrix code,PDF41 7 code,QR code real -timely.
