Image calibration
A digital image is captured. The captured digital image includes a calibration pattern. The calibration pattern includes displayed information about the calibration pattern. The displayed information is read to obtain calibration information about the captured digital image. A new image is generated. The calibration information is stored with the new image.
1. A method comprising:
(a) capturing a digital image that includes both a physical object and a calibration pattern, said calibration pattern including displayed information about said calibration pattern, where said calibration pattern and said physical object are non-overlapping with one another in said digital image;
(b) reading, from said captured digital image that includes both said physical object and said calibration pattern, said displayed information about said calibration pattern to determine calibration information pertaining to said physical object;
(c) generating a new image of said physical object, said new image not including said calibration pattern;
(d) adding said calibration information to said new image;
(e) wherein said calibration information is said added to said new image by including said calibration information as metadata for said new image within an image file containing said new image;
(f) wherein said calibration information includes resolution scaling information;
(g) capturing another digital image that includes both another physical object and another calibration pattern, said another calibration pattern including another displayed information about said another calibration pattern, where said another calibration pattern and said another physical object are non-overlapping with one another in said another digital image;
(h) reading, from said another captured digital image that includes both said another physical object and said another calibration pattern, said another displayed information about said another calibration pattern to determine another calibration information pertaining to said another physical object;
(i) generating another new image of said another physical object, said another new image not including said another calibration pattern;
(j) adding said another calibration information to said another new image.
2. The method of claim 1 wherein said another calibration information is said added to said another new image by including said another calibration information as metadata for said another new image within another image file containing said another new image.
3. The method of claim 2 wherein said another calibration information includes another resolution scaling information.
4. The method of claim 3 further comprising:
(a) displaying said new image on a display based upon said resolution scaling information said added to said new image;
(b) simultaneously displaying said another new image on said display based upon said another resolution scaling information said added to said another new image;
(c) where said resolution scaling information is different than said another resolution scaling information.
