Camera Tower Instructions
There are no explicit instructions for constructing the camera tower. The camera should be
mounted at a height such that the camera can see the full width of the table and just inside
the edges of the red duct tape (the tape should not appear on the camera). Refer to the
table diagram. Adjust the focus of the
camera either visually or by the old focusing method. Place a ball in each corner of the
view area to verify the adjustments. The ball should appear in each corresponding corner in
the image of the table
The design for the tower used at USC can be seen in the following diagrams and pictures:

The Old calibration instructions are still up to provide a further
understanding into how the camera signal looks.
