Along a result I just found your question, so I think I come too late.

If not I think your problem car easily be resolved, it exists since years and is called Sikuli .

While it's for testing purposes, I have been using it in the same way as you need : compare a reference and a production image. Based on OpenCV it does it very well.

It's not a trivial task by any stretch of the imagination. Two images of the same identical object will always be different according to lightning conditions, perspective, shooting angle, etc.

Basically you need to: 1. Process the 2 images into "digested" data - dominant color, shapes, etcw 2. Design and run your own similarity algorithm between the 2 objects

You may want to look at Feature detectors in OpenCV: Surf, SIFT, etc.
