Abstract

Embodiments of the present invention are directed to document processing, and more particularly to systems and methods that can utilize relative positions between the content of the document and a decodable indicia affixed to the document. In one embodiment, indicia reading terminals are provided that include an imaging module for capturing a frame of image data of a document. The document can include one or more decodable indicia such as a form barcode and various content fields, which delineate particular content of the document. The form barcode can include information respecting the form design and form design data. This information can be used to process the content of the document such as by providing coordinates or similar location and positioning metrics for use in processing the content of the document. In one example, the frame of image data is analyzed to identify the form barcode, from which the relative location of the content fields can be discerned without extensive processing of the frame of image data.

Claims

1. A system, comprising:

an indicia reading terminal comprising an image sensor;

wherein the system is operative to, in response to an operator initiated command, capture a frame of image data and process the frame of image data in an attempt to decode a form barcode on a document;

wherein the system is operative to determine, from the captured frame of image data, a configuration of the form barcode on the document and, based on the determined configuration of the form barcode identify the form barcode on the document; and

wherein processing of the frame of image data on a first document having the form barcode disposed thereon is faster than processing of the frame of image data on a second document without the form barcode.

2. The system of claim 1, wherein the system is operative to determine a configuration of the form barcode based on a form factor of the form barcode.

3. The system of claim 1, wherein the system is operative to determine a configuration of the form barcode based on a size, a shape, and/or a color of the form barcode.

4. The system of claim 1, wherein the system is operative to determine a configuration of the form barcode based on a printing material of the form barcode.

5. The system of claim 4, wherein the printing material comprises an ultraviolet ink and/or an infrared ink.

6. The system of claim 1, wherein the system is operative to determine a configuration of the form barcode based on a barcode indicator of the form barcode.

7. The system of claim 1, wherein the system is operative to determine a configuration of the form barcode based on a pre-assigned geometric pattern of the form barcode.

8. The system of claim 1, wherein the system is operative to:

based on information stored in the form barcode, identify a coordinate system on an image plane from information stored in the form barcode; and

identify a corner of the form barcode, wherein the coordinate system is located relative to the identified corner.

9. A system, comprising:

an indicia reading terminal comprising an image sensor;

wherein the system is operative to, in response to an operator initiated command, capture a frame of image data and process the frame of image data in an attempt to decode a form barcode on a document;

wherein the system is operative to, based on information stored in the form barcode, identify a coordinate system on an image plane;

wherein the system is operative to identify, relative to the form barcode and in the coordinate system, a position of a content field located on the document;

wherein the system is operative to, based on the identified position of the content field on the document, identify portions of content of the document other than the content field; and

wherein processing of the frame of image data on a first document having the form barcode disposed thereon is faster than processing of the frame of image data on a second document without the form barcode.

10. The system of claim 9, wherein the system is operative to, based on the identified position of the content field on the document, identify portions of content of the document comprising a title, an identification number, and/or a page number.

11. The system of claim 9, wherein the system is operative to, based on the identified position of the content field on the document, identify portions of content of the document comprising personal identification information.

12. The system of claim 9, wherein the system is operative to, based on the identified position of the content field on the document, identify portions of content of the document comprising a signature, a stamp, and/or a fingerprint.

13. The system of claim 9, wherein the system is operative to, based on the identified position of the content field on the document, identify portions of content of the document comprising a number of check boxes, an orientation of a check box, a location of a check box, and/or collected information indicated by a check box.

14. The system of claim 9, wherein the system is operative to identify, relative to the form barcode and in the coordinate system, a position of multiple content fields located on the document.

15. The system of claim 9, wherein the system is operative to identify a corner of the form barcode, wherein the coordinate system is located relative to the identified corner.

16. A system, comprising:

an indicia reading terminal comprising an image sensor;

wherein the system is operative to, in response to an operator initiated command, capture a frame of image data and process the frame of image data in an attempt to decode a form barcode on a document;

wherein the system is operative to determine, from the captured frame of image data, a configuration of the form barcode on the document and, based on the determined configuration of the form barcode identify the form barcode on the document;

wherein the system is operative to, based on information stored in the form barcode, identify a coordinate system on an image plane;

wherein the system is operative to identify, relative to the form barcode and in the coordinate system, a position of a content field located on the document;

wherein the system is operative to, based on the identified position of the content field on the document, identify portions of content of the document other than the content field; and

wherein processing of the frame of image data on a first document having the form barcode disposed thereon is faster than processing of the frame of image data on a second document without the form barcode.

17. The system of claim 16, wherein the system is operative to determine a configuration of the form barcode based on a form factor of the form barcode.

18. The system of claim 16, wherein the system is operative to determine a configuration of the form barcode based on a printing material of the form barcode.

19. The system of claim 16, wherein the system is operative to, based on the identified position of the content field on the document, identify portions of content of the document comprising personal identification information.

20. The system of claim 16, wherein the system is operative to identify a corner of the form barcode, wherein the coordinate system is located relative to the identified corner.
