  • Patent number: 7273175
    Abstract: The present application relates to a method, an apparatus and a storage medium for locating QR codes. For automatically locating a plurality of QR codes in image of any size, the invention provides an apparatus for locating at least one QR code in an image, comprising: characteristic ratio detection means for detecting the potential QR code location symbol areas by carrying out a plurality of detections for detecting the characteristic ratio of the QR code; critical edge detection means for detecting the critical edges of the potential QR code location symbol areas so that the false areas are excluded; location symbol grouping means for matching the detected QR code location symbol areas into potential QR codes; and verification means for excluding the false QR codes. The invention also provides a corresponding method for locating at least one QR code.
