METHOD AND APPARATUS FOR AUTO-DETECTING ORIENTATION OF FREE-FORM DOCUMENT USING BARCODE |
摘要 |
Method and apparatus of detecting orientation of document using a barcode decoding. The method includes (1) capturing an image of the document with an imaging arrangement having a solid-state imager; (2) determining a presence of a barcode in the captured image of the document; (3) decoding the barcode; (4) determining an up-direction of the document as a function of an orientation of the barcode in the document; and (5) setting an orientation of the document in the captured image based upon the up-direction of the document. In one implementation, the barcode is configured with orientation data indicating the up-direction of the document.
