Although new application areas are being conceived by our clients almost daily, in sectors as diverse as Security, Logistics and Building Management, on this occasion RTT's generic Visual-AI technology has been applied to meet the needs of commercial sport.
To illustrate the elements of an RTT Target Tracking System, lets take a closer look at a currently operational site*.
The starting point is to know the physical Action Area of interest - which could be as small as a doorway, or as extensive as an entire cityscape - but here, it is the 450m running track of a premier Greyhounds Racing stadium, in the UK.
RTT's generic tracking system was required to identify and locate - in real time - the six racing greyhounds, plus the mechanical hare.
The facility, being an all-year, all-weather business, required a robust technology that would not only produce reliable tracking data under a wide variety of conditions, but also one that could be economically deployed and maintained.

RTT engineers installed the required 'iCAMs' around the track's permineter and took the necessary measurements from the venue in order to calibrate the system for accurate data.
The iCAM image data is transmitted via network links back to the operations desk - termed a 'PreVision Console' - where it is processed to derive a complete view of the whole scene, its objects, and the activities occurring within it – with all of this taking-place in real time (sub 300 milliseconds), as the action happens live on the track !

The PreVision Console itself consists of the necessary hardware elements for advanced video signal management, the running of RTT's unique system software, and of course, an operator's interface.
Once installed and calibrated, the RTT real time tracking system may then be left to passively watch the unfolding scene before it, as the 'objects' within the Action Area go about their regular business. It will either automatically 'lock-on' to any predefined targets (greyhounds for example), or, the operator can interactively select dynamic targets for immediate tracking, e.g. event-officials, vehicles, etc.
The real time tracking data produced is both archived to a database for use by the governing body and others, as well as being broadcast live across the Internet and other channels to multiple end-client platforms, such as PCs, PDAs and Mobile Phones.
