  • Code detection and decoding system
    Patent number: 9355293
    Abstract: A method (2304) of decoding a QR code having two initially detected finder patterns (2901, 2902; 2911, 2912) is provided. The method forms (2402) a pattern matching template (2700, 2800) based on characteristics of the detected finder patterns and determines (2403) at least one candidate region (2904, 2905; 2913, 2914) about the detected finder patterns. The candidate region is typically based at least on the relative positions of the detected finder patterns. The method detects (2404) a previously undetected third finder pattern of the QR code in the at least one candidate region by correlating content of the candidate region with the pattern matching template. With the identified third finder pattern and each of the two initially detected finder patterns, decoding (2305) the QR code can then be performed. Also disclosed is a method of detecting a two-dimensional code comprising known target features and coded data in an image.
