Abstract:
1. A method for decoding captured image information performed by a computer having a memory and a processor, the method comprising: with a processor, capturing image information, wherein the image information includes a predefined grid orientation comprising a plurality of pixels representing a plurality of corners, determining a first angle to rotate the captured image information for decoding based on the predefined grid orientation, rotating the captured image information by the determined first angle to provide a first rotated image, determining a corner of the plurality of corners that is missing from the first rotated, determining a second angle to rotate the first rotated image based upon the determined missing corner, rotating the first rotated image by the determined second angle to provide a second rotated image, decoding said second rotated image, error correcting the decoded image, and determining locations associated with the error corrected image,
