Computer-linked cameras placed in the stands around each goal capture ball’s motion,which is then read by a computer in real-time.
Ball’s path is tracked on each of the cameras.These separate views are then combined to produce an accurate 3D representation of the ball’s path.
High speed TV cameras capture images at up to 500 frames per second.
The system would signal a goal to the referee in half a second who would hear a distinct beep through an ear-piece or message to a watch Ball.
Chip sensor in ball is triggered by magnetic field and signals computer to send “GOAL”message.Wires run around the goal mouth to form a magnetic field.
Six Cameras around the goal track the ball and the system software creates 3D images which capture the position of the ball in relation to the goal line.
If the Ball crosses the line,an encrypted signal is transmitted to he referee via watch or a ear piece within half a second.
