Methods, systems, apparatus, and articles of manufacture for document scanning

1. An apparatus comprising:

a base structured to position a mobile device, the base including an opening corresponding to a camera of the mobile device; and

at least two rectangular side panels couplable to and foldable toward the base, the side panels structured to maintain a first distance between the base and a target document, the side panels slidable along the target document, the side panels to include one or more reference markers positioned at bottom corners of the side panels, the bottom corners proximate to the target document.

2. The apparatus of claim 1 , wherein at least one of the base or the side panels are a transparent plastic material.

3. The apparatus of claim 1 , further including a transparent bottom panel proximate a surface upon which the target document is positioned, the transparent bottom panel coupled to at least one of the side panels, the transparent bottom panel slidable along the surface.

4. The apparatus of claim 1 , wherein the side panels are rotatable between a first position and a second position, the side panels substantially parallel to the base in the first position, the side panels substantially perpendicular to the base in the second position.

5. The apparatus of claim 1 , wherein at least one of the side panels includes a height indicator to indicate a height of the side panels.

6. The apparatus of claim 5 , wherein the height indicator includes at least one of text, a barcode, or a numerical value.

7. The apparatus of claim 1 , wherein the side panels are first side panels having a first height, further including second side panels having a second height, the second height different from the first height, the first side panels or the second side panels structured to be coupled to the base.

8. The apparatus of claim 1 , wherein the side panels are removably coupled to the base.

9. The apparatus of claim 1 , wherein the one or more reference markers are structured to be detectable by an image processor to facilitate image stitching.

10. An apparatus comprising:

at least two side panels couplable to and foldable toward a base, the base structured to position a mobile device above a target document, the side panels structured to maintain a first distance between the base and the target document;

a transparent bottom panel coupled to at least one of the side panels, the transparent bottom panel slidable along the target document; and

reference markers positioned at corners of the transparent bottom panel.

11. The apparatus of claim 10 , wherein at least one of the base or the side panels are a transparent plastic material.

12. The apparatus of claim 10 , wherein the base includes an opening, the opening aligned with a position of a camera of the mobile device.

13. The apparatus of claim 10 , wherein the side panels are rotatable between a first position and a second position, the side panels substantially parallel to the base in the first position, the side panels substantially perpendicular to the base in the second position.

14. The apparatus of claim 10 , wherein at least one of the side panels includes a height indicator to indicate a height of the side panels.

15. The apparatus of claim 10 , wherein the side panels are first side panels having a first height, further including second side panels having a second height, the second height different from the first height, the first side panels or the second side panels to be coupled to the base.

16. The apparatus of claim 10 , wherein the height indicator includes at least one of text, a barcode, or a numerical value.

17. An apparatus comprising:

means for holding a mobile device, the holding means including an opening corresponding to a camera of the mobile device;

means for supporting to maintain a first distance between the holding means and a target document, the supporting means pivotably coupled to the holding means, the supporting means including reference markers positioned to be in a field of view of the camera, the reference markers being detectable by means for stitching images;

and wherein at least one of the holding means or the supporting means is formed of a transparent plastic material.

18. The apparatus of claim 17 , wherein at least one of the supporting means includes means for indicating height, the height indicating means to indicate a height of the supporting means.

19. The apparatus of claim 17 , further including means for sliding coupled to at least one of the supporting means, the sliding means proximate a surface upon which the target document is positioned, the sliding means slidable along the surface.

20. The apparatus of claim 19 , wherein the reference markers are positioned at corners of at least one the sliding means or the supporting means.
