Yes it would, but I can't get a camera with a high enough resolution to still give me the kind of accuracy I need.  I need to position the item within +- .005 inches, so I need to have at least 200 pixel/inch.  Ideally, I'd like to set up the camera to get 1000 pixel/inch.  For the current item (7.672"x7.672"), that would mean a roughly 59 MP camera.  However, I'm supposed to make this system handle up to a 15"x10" piece.  Something this size would need a 150 MP camera to be able to see the whole thing at 1000 pixels/inch.  I guess if I lowered the number of pixels/inch it might be okay, but it would be nice if I didn't have to.

Even if I could get a camera with this high of resolution, I think it would just be easier in terms of processing time to use two smaller pictures, one on each of two corners, but I'm open to suggestions if you think there is another way to do this.

Let me know if you know of cameras that could meet these MP needs, and thanks for the feedback.
