One of the issues with the camera is that the table will not be parrallel to the edge of the image unless the person can take a perfect image.
This means the image needs to be rotated to make it straight.
One way of doing this is by using a rotation matrix :

The co-ordinates also needed to be scaled so that they match the co-ordinates and size in the physics engine.
A class was to be written which would rotate and scale the image so that the co-ordinates could match the physics model.
