Research on Barcode Image Binarization in Barcode Positioning System
نویسندگان
چکیده
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.

A method for robot indoor automatic positioning and orientating based on two-dimensional (2D) barcode landmark is proposed. By using the scheme of the 2D barcode for reference, a special landmark is designed which is convenient to operate and easy to recognize, contain coordinates of their absolute positions and have some ability to automatically correct errors. Landmarks are placed over the “c...
