Abstract

A system comprising: a document holder; an image sensor directed toward the document holder; a polarized filter between the image sensor and the document holder; a filter motor configured to rotate the polarized filter; one or more processors; and at least one memory having stored thereon computer program code that, when executed by the one or more processors, instructs the one or more processors to: control the filter motor to rotate the polarized filter; control the image sensors to capture a plurality of images of a document within the document holder, the plurality of images corresponding to a respective relative orientations of the polarized filter to the document; identify a feature of the document; and output, in response comparing respective visual characteristics of the feature of the document to corresponding expected visual characteristics of the first feature for the document, an indication of a verification of the document.

First claim

We claim:

1. A system comprising:
at least one processor; and
at least one memory having stored thereon computer program code that, when executed by the one or more processors, instructs the one or more processors to:
receive a first plurality of images of a document at a first set of capture conditions;
analyze the first plurality of images of the document at the first set of capture conditions;
adjust from the first set of capture conditions to a second set of capture conditions for a second plurality of images based on the analysis of the first plurality of images;
receive the second plurality of images of the document at the second set of capture conditions;
identify a first feature of the document visible within at least one of the second plurality of images, the first feature having visual characteristics that differ between at least one of the first plurality of images and the at least one of the second plurality of images; and
output, in response to comparing respective visual characteristics of the first feature of the document in the at least one of the second plurality of images to corresponding expected visual characteristics of the first feature of the document, an indication of acceptance of the document.

2. The system of claim 1 , the computer program code, when executed by the one or more processors, further instructs the one or more processors to:
identify a second feature of the document; and
determine an indication of an identity of the document using optical character recognition of the second feature.

3. The system of claim 2 , the computer program code, when executed by the one or more processors, further instructs the one or more processors to:
determine the expected visual characteristics for the first feature based on the indicated identity from the second feature.

4. The system of claim 1 , wherein the visual characteristics of the first feature comprise a machine-readable code.

5. The system of claim 4 , wherein the machine-readable code indicates the identity of the document.

6. The system of claim 1 , wherein the first plurality of images and the second plurality of images comprise videos.

7. A method comprising:
receiving a first plurality of images of a document at a first set of conditions;
analyzing the first plurality of images of the document at the first set of conditions;
adjusting from the first set of conditions to a second set of conditions for a second plurality of images based on the analysis of the first plurality of images;
receiving the second plurality of images of the document at the second set of conditions;
identifying a feature of the document within at least one of the second plurality of images, the feature having characteristics that differ between at least one of the first plurality of images and the at least one of the second plurality of images; and
outputting, in response to comparing respective characteristics of the feature of the document in the at least one of the second plurality of images to corresponding expected characteristics of the feature of the document, an indication of acceptance of the document.

8. The method of claim 7 , further comprising:
receiving an indication of the first set of conditions.

9. The method of claim 7 , wherein the first set of conditions and the second set of conditions comprise different lighting variations.

10. The method of claim 7 , wherein the first set of conditions and the second set of conditions comprise different angle variations.

11. The method of claim 7 , wherein the first set of conditions and the second set of conditions comprise different filter variations.

12. The method of claim 7 , wherein adjusting the second set of conditions further comprises utilizing a filter.

13. The method of claim 7 , wherein adjusting the second set of conditions future comprises utilizing a light source.

14. The method of claim 7 , further comprising:
determining an identity of the document using optical character recognition; and
determining the expected characteristics for the feature based on the determined identity.

15. The method of claim 7 , wherein the characteristics of the feature comprise a machine-readable code.

16. A system comprising:
one or more cameras;
at least one processor; and
at least one memory having stored thereon computer program code that, when executed by the one or more processors, instructs the one or more processors to:
control the one or more cameras to receive a first plurality of images of a document at a first set of capture conditions;
analyze the first plurality of images received at the first set of capture conditions;
adjust a configuration to a second set of capture conditions based on the analysis of the first plurality of images;
control the one or more cameras to receive a second plurality of images of the document at the second set of capture conditions;
identify a feature of the document visible within at least one of the second plurality of images, the feature having visual characteristics that differ between at least one of the first plurality of images and the at least one of the second plurality of images; and
output, in response to comparing respective visual characteristics of the feature of the document in the at least one of the second plurality of images to corresponding expected visual characteristics of the feature of the document, an indication of acceptance of the document.

17. The system of claim 16 , wherein adjusting the configuration to a second set of capture conditions further comprises:
adjusting the configuration of a filter.

18. The system of claim 16 , wherein adjusting the configuration to a second set of capture conditions further comprises:
adjusting the configuration of a light source.

19. The system of claim 16 , wherein the visual characteristics of the feature comprise a machine-readable code.

20. The system of claim 19 , wherein the machine-readable code is viewable at the second set of capture conditions.

21. The system of claim 16 , wherein the first plurality of images at the first set of capture conditions are from a first camera of the one or more cameras and the second plurality of images at the second set of capture conditions are from a second camera of the one or more cameras.

22. The system of claim 21 , wherein the second camera is different from the first camera.

23. The system of claim 22 , wherein the second camera is in a different position from the first camera.

24. The system of claim 1 , wherein the first plurality of images at the first set of capture conditions are received from a first camera, and the second plurality of images at second set of capture conditions are received from a second camera.

25. The method of claim 7 , wherein the first plurality of images at the first set of conditions are received from a first camera, and the second plurality of images at the second set of conditions are received from a second camera.

26. The method of claim 9 , wherein the different lighting variations further comprise one or more of light source position, color, intensity, wavelength, or combinations thereof.

27. The method of claim 12 , wherein the filter is a polarizing filter.

28. The system of claim 2 , wherein the second feature is at least partially combined with the first feature.
