QR-code is used in various scenes. For example, in motor vehicle industry information of part number and quantity is QR-coded, these is affixed statement of delivery and receipt, and is used in order and inspection. QR-code affixed soft material(paper etc...) is easy to distort. If QR-code has distortion, it can’t be recognized by usual method. In this study, we propose method to recognize QR-code with distortion. SIFT is used in the proposed method. We composed between precision of usual method and proposed method using deformed images(scaling, rotation and bending). The recognition by proposed method is higher precision 10 degree for rotation angle, 0.002 for curvature than by usual method. |
