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. Posts
