How To Make An Augmented Reality Target Shooter Game With OpenCV: Part 4/4

In this final part, you will be using Open CV's tracking features to finish your augmented reality shooting game.

This is a companion discussion topic for the original entry at

How to identify target irrespective of its size.

(If you’re searching an input frame for a 200 x 200 pixel target marker, then you’re going to have to hold the camera at just the right distance away from the marker so that it fills approximately 200 x 200 pixels on the screen.)

In the above scenario why do we need to hold camera at a certain distance?

The completed source code in this part of tutorial and in all other 3 parts, the link to the source code file is broken. Can this be fixed please?

I would like for the source code link to be fixed as well!

This tutorial is more than six months old so questions are no longer supported at the moment for it. We will update it as soon as possible. Thank you! :]
