Abstract: Verfahren und Vorrichtung zum Erkennen der Ausrichtung von Dokumenten mit Strichcode-Decodierung. Das Verfahren beinhaltet (1) das Erfassen eines Bildes des Dokumentes mit einer Bildgebungsanordnung mit einem Festkörper-Imager; (2) das Feststellen des Vorhandenseins eines Strichcodes in dem erfassten Bild des Dokuments; (3) das Decodieren des Strichcodes; (4) das Ermitteln einer Aufrecht-Richtung des Dokuments in Abhängigkeit von einer Ausrichtung des Strichcodes in dem Dokument; und (5) das Einstellen einer Ausrichtung des Dokuments in dem erfassten Bild auf der Basis der Aufrecht-Richtung des Dokuments. In einer Ausführung ist der Strichcode mit Ausrichtungsdaten konfiguriert, die die Aufrecht-Richtung des Dokuments anzeigen.

Abstract: 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.

Abstract: Method and apparatus of detecting orientation of document using OCR. Decoding. The method includes (1) capturing an image of a document having a text string with an imaging arrangement having a solid-state imager; (2) storing into a memory a captured image of the document obtained by the solid-state imager; (3) performing OCR decoding on the text string in the captured image of the document to find an up-direction of the document in the captured image; and (4) setting an orientation of the document in the captured image based upon the up-direction of the document. In one implementation, the text string includes an OCR string specifically designed for OCR decoding.

Abstract translation: 使用OCR检测文档的方向的方法和装置。 解码。 该方法包括：（1）利用具有固态成像器的成像装置拍摄具有文本串的文档的图像; （2）将通过固态成像器获得的原稿的拍摄图像存储到存储器中; （3）对文档的拍摄图像中的文本串执行OCR解码以找到拍摄图像中的文档的上行方向; 和（4）基于文档的向上方向来设置拍摄图像中的文档的取向。 在一个实现中，文本串包括专门为OCR解码设计的OCR字符串。
