I would like to track the position of a ball that moving from one end of a playing surface to the other about 150 ft away. The ball starts at rest and takes about 10-30 sec to come to rest at the other end of the playing surface. As the ball moves from one end to the other, it travels in a slight arc.
I have read many of the posts indicating that using a gyroscope and accelerometer has too much error and that using wifi RSSI is too noisy to allow triangulation.
aI have been looking at a system based on cameras located above the surface. I think I am able to track the ball with a software based on OpenCV but I am having difficultly handling multiple cameras.
I am intrigued by your thought of the grid of wires in the floor. How would that work?
A wacom pen-tablet uses grid of wires, and a pen with a coil.
I read: "the horizontal and vertical wires of the tablet operate as both transmitting and receiving coils". But that is about the same I know about it.
