Abstract

Methods and systems for copying media. A telescopic and swivel configured pole includes an arm that supports a camera for acquiring an image of media. A flat bed is configured with markers that facilitate imaging and a detection of the DPI of the image of the media located on the flat bed within a boundary of the markers. The pole is adjustable moveable in a telescopic and/or swivel manner for an acquisition and reproduction of the image in a dimensional scale representative of the actual scale of the media.

Claims

1. A system for copying media, said system comprising:

a telescopic and swivel configured pole having an arm configured to support a smartphone for acquiring an image of media with a camera associated with said smartphone, wherein said media is located below said smartphone and facing said camera of said smartphone; and

a flat bed configured with markers that facilitate imaging and a detection of a DPI of said image of said media located on said flat bed within a boundary of said markers, wherein said pole is moveable in a telescopic and/or swivel manner for an acquisition and a reproduction of said image by said camera.

2. The system of claim 1 wherein said DPI is detected with an imaging algorithm.

3. The system of claim 2 wherein said imaging algorithm comprises a corner detection algorithm.

4. The system of claim 3 further comprising sensor grids that assist said camera of said smartphone to identify a size of said media and adjust a height of said camera above said media for scanning of said media by said camera associated with said smartphone.

5. The system of claim 4 wherein said flat bed is configured with a plurality of grid markings that assist said camera in identifying said size of said media and adjusting said height of said camera for scanning said media and wherein said corner detection algorithm detects said grid markings for said camera.

6. The system of claim 2 wherein said detection comprises a local document detection with respect to said media, said local document detection including:

(A) capturing an image of said image placed in a grid bed configured from said flat bed;

(B) detecting at least one corner and performing DIP calculation;

(C) implementing edge detection of said media; and

thereafter lifting said document.

7. The system of claim 1 wherein said telescopic and swivel configured pole comprises a telescopic height adjuster.

8. The system of claim 2 wherein said DPI is calculated and stored in an image header associated with said image, wherein said image header is triggerable for printing.

9. The system of claim 1 wherein said camera comprises a digital camera and wherein said smartphone is supported on said arm by a smartphone holder for maintaining said smartphone and wherein said swivel manner of said telescopic and swivel configured pole comprises a bidirectional direction.

10. A method for copying media, said method comprising:

providing a telescopic and swivel configured pole having an arm configured to support a smartphone for acquiring an image of media with a camera associated with said smartphone, wherein said media is located below said smartphone and facing said camera of said smartphone; and

imaging and detecting a DPI of said image of said media with a flat bed configured with markers that facilitate said imaging and a detection of said DPI of said image of said media located on said flat bed within a boundary of said markers, wherein said pole is moveable in a telescopic and/or swivel manner for an acquisition and a reproduction of said image by said camera.

11. The method of claim 10 further wherein said DPI is detected with an imaging algorithm.

12. The method of claim 11 wherein said imaging algorithm comprises a corner detection algorithm.

13. The method of claim 11 further comprising calculating and storing said DPI in an image header associated with said image, wherein said image header is triggerable for printing.

14. The method of claim 12 wherein said detection comprises a local document detection with respect to said media, said local document detection including:

(A) capturing an image of said image placed in a grid bed configured from said flat bed;

(B) detecting at least one corner and performing DIP calculation;

(C) implementing edge detection of said media; and

thereafter lifting said document.

15. The method of claim 12 further comprising:

providing sensor grids that assist said camera of said smartphone in identifying a size of said media and adjusting a height of said camera above said media for scanning of said media by said camera associated with said smartphone.

16. The method of claim 15 wherein said flat bed is configured with a plurality of grid markings that assist said camera in identifying said size of said media and adjusting said height of said camera for scanning said media and wherein said corner detection algorithm detects said grid markings for said camera.

17. The method of claim 10 wherein said camera comprises a digital camera and wherein said smartphone is supported on said arm by a smartphone holder for maintaining said smartphone and wherein said swivel manner of said telescopic and swivel configured pole comprises a bidirectional direction.

18. The method of claim 10 wherein said telescopic and swivel configured pole comprises a telescopic height adjuster.

19. A system for copying media, said system comprising:

a telescopic and swivel configured pole having an arm configured with a smartphone holder that supports and maintains a smartphone for acquiring an image of media with a camera associated with said smartphone, wherein said media is located below said smartphone and facing said camera of said smartphone, wherein said telescopic and swivel configured pole includes a telescopic height adjuster and wherein said smartphone holder comprises a curved bracket for holding said smartphone securely on said arm;

a flat bed configured with markers that facilitate imaging and a detection of a DPI of said image of said media located on said flat bed within a boundary of said markers, wherein said pole is moveable in a telescopic and/or swivel manner for an acquisition and a reproduction of said image by said camera; and

an imaging algorithm for use in detecting said DPI and wherein said DPI is calculated and stored in an image header associated with said image, wherein said image header is triggerable for printing.

20. The system of claim 19 wherein said flat bed is configured with sensor grids and a plurality of grid markings that assist said camera of said smartphone to identify a size of said media and adjust a height of said camera above said media for scanning of said media by said camera associated with smartphone, and wherein said swivel manner of said telescopic and swivel configured pole comprises a bidirectional direction, and wherein said imaging algorithm comprises a corner detection algorithm.
