OpenCV 3.x with Python By Example - Second Edition

Let's add some movements

Now that we know how to add a virtual pyramid, let's see if we can add some movements. Let's see how we can dynamically change the height of the pyramid. When you start, the pyramid will look like this:

If you wait for some time, the pyramid gets taller and will look like this:

Let's see how to do it in OpenCV Python. Inside the augmented reality code that we just discussed, add the following snippet at the end of the __init__ method in the Tracker class:

self.overlay_vertices = np.float32([[0, 0, 0], [0, 1, 0], [1, ...
