It has been taken serious because of it’s large information and low error rate. It develops very quickly and has already been applied in industry,merce,publishing,medical sanitation and so on. It can be seen from the actualities in our country that the use of BarCode is influenced by the printing quality and goods transportation, and besides, the traditional mode of recognition is using optical scanner so that the recognitinon will be consequentially affected by the different reflection of code image by the light. Different BarCode has different recognition process. This paper researches into a method based on digital image processing mode to resolve the problems of poor printing quality and code distortion, which uses the vidicon to take pictures of code images so as to avoid the traditional questions brought by the linebyline scanning. And then applies the digital image processing algorithms to recognize the code, which includes two steps: the first is image pretreatments, the second is using statistic method and the distance of edge to similar edge method to recognize the code character. Comparing with decoding with special BarCode identification hardware, decoding with software is more flexible, and the cost is also paratively low. Hence, BarCode has a very clear future of development. This research is realized by Matlab.
