intent of this document is to give basic information and
instructions about the video jump system. Theory of Operation
The video jump system uses computer and video technology to be
able to measure jump distances. Buoys are placed in the water in
front of the jump roughly in squares. The skier lands inside
these squares. The buoys are surveyed so that their exact
positions are known. These positions are fed into the computer.
A video camera is set up perpendicular to the center of each box
of buoys. This video picture is put on the computer screen with
a graphics overlay. The overlay is used to calibrate the buoys
to their screen positions. Mathematical transposition is used to
create a mathematical representation of any screen position
inside the square to its actual physical location and then
calculate the distance betwe
