Abstract
A method for processing a matrix barcode displayed in three dimensions to extract data represented thereby involves capturing the component images of the three-dimensional representation. The method includes receiving a first component image of the matrix barcode and receiving a second component image of the matrix barcode as the two images are displayed on a display device. After the two images have been received, the first component image and the second component image of the matrix barcode are captured on an image capture device. Then depth information between elements of the matrix barcode presented in the first and second component images is determined and additional data represented in such depth information is extracted.
