MaxiCode is a fixed-size matrix 2D barcode, and it is often used by transportation industry to record the transportation information of packages. In our system, we process the MaxiCode’s picture which is taken by the camera phone. Firstly, the edge points of the picture are used for the image binarization. Next, we use the thinned connected components to locate the Finder Pattern of MaxiCode, and we find the Orientation Pattern of Maxicode to rotate the code into the right position. Then we extract the boarders of MaxiCode, and we use inverse perspective transformation to rectify the code shape. Finally, the run-length of data points are extracted by horizontal projection, and the modules corresponding to the run-length are taken to decode. Experimental results show that the system can decode the MaxiCode image correctly and efficiently. Chen, Ling-Hwei 陳玲慧 2009 學位論文 ; thesis 46 en_US |
