FIFA (federation internationale de football association)

Referee errors Improvements Other sports (tennis,

football, hockey, etc.)

Mandatory Features

Implement beside/above the goal camera that is linked to a computer

Uploading pictures generated from camera to the computer

Detection system will give response whether the goal was scored or not

Building a launcher (ping pong) that will move in semicircle/straight path around the goal

Shooting from the gun toward specific target by moving it horizontally/vertically

Extra Features

Detect different shapes of objects (foot, hand, ball, etc..)

Feedback ability from detector to the speaker

Detect what coordinates the ball has entered

Accurate control - targeting

Measure the speed of a ball

The types of Goal Line Technology are:

Sensor on Football (Microchip in ball)

Sensor on Goal line (Magnetic Field on posts)

Personal Computer 1-2 VGA cameras (30-60 fps) USB/Firewire interface

This part will be done using 1-2 cameras

The cameras will send frames to computer and Matlab will process these frames.

Using Image Processing Toolbox, these frames will be processed in real time and IPT tool will determine if the ball has passed the line or not.

Using Image Processing Toolbox, these frames will be processed in real time

The frames will be turned into black and white.

The ball will be segmented out of the picture using image subtraction

The center of ball will be found using regionprops command. Then decision will be made based on coordinates of the center.

PRECISION whether the ball passed the goal line or not / Speed of ball vs frame rate

Real time response/Fast processing

Multi-camera processing capability

Ball speed control

Dependent upon previous project especially programming
