TRACAB image tracking system™

The TRACAB Image Tracking System™ uses image processing technology to identify the position of all moving objects in a sports arena in real-time. The outcome of the analysis is a data feed with X, Y and Z coordinates for all objects. The precision of the measurements is below one decimetre. The data feed is used by different applications serving various customer needs.

One of the biggest advantages is that the system uses no transmitters or any other kind of device on the players or the ball. The system does not in any way interfere with the game.

A Proven Solution

The TRACAB system has been modified and developed considerably since the first production in the Swedish Royal League Final in the spring of 2005. During over 3,000 live productions the system has been exposed to numerous challenges in terms of weather, light/stadia conditions, logistic challenges etcetera. This has shaped the system to where it is today - the only proven solution that can deliver true three dimensional tracking of a football match in real time.

Multi Camera Units

The system consists of two small multi-camera units. By using more than one camera the system gets less sensitive to a camera failure, even if one camera fails the unit will still be operational. It also provides the camera units with the feature of dynamic resolution, meaning that the individual cameras can be angled so that the camera unit delivers a higher resolution in the parts of the pitch where there are most crowded and occluded situations, such as the penalty boxes.

Stereo Vision Technology

The TRACAB system is based on stereo vision technology. This means that every inch of the pitch is constantly covered by at least two cameras. The x, y, z measurements for the objects on the pitch are made through analysing both these images and, most importantly, the difference between them. This method results in true three dimensional tracking - in real time.
