摘要：Aiming at the disadvantages of the traditional positioning technology, barcode positioning system is introduced in this paper. Based on Otsu method, a novel barcode image binarization is put forward by comparing varieties of image binarization methods domestically and abroad. Moreover, we have a systematic research on histogram and binarization mechanism, and also give the calculation of histogram and derive a formula of Otsu method. Finally, the histogram and binarization of one-dimensional barcode image are realized with the specific examples. After experiments for scanned barcode image, the result has demonstrated effectiveness of the method.
