I got my camera calibration completed and the image looks very good. Now can I determine what my X,Y position is if I know my distance from the object, and how can I determine this??

Thank You

So once the image is un-distorted  some key things are now true. If I image an object at a particular distance and then image that object at a different distance then I have a ratio of sizing apparent to the camera based on distance.So if I measure a "dime"  on the surface of a flat board at 20" away, and then I measure the dime at 30" away, I will see an difference in the pixels that see the dime and their column and row starting and ending points. Since the entire grid is now properly in proportion in both "X" and "Y" it is possible to map the object to within a pixel.

Can someone qualify my thoughts.
