If you like to think you are safe from the prying roadside cameras, then think again. This month, Racal Messenger will be unveiling an updated version of its Talon system, which, in multi-national plate recognition trials conducted during extreme weather conditions, acheived a 95% accuracy rate. The system, currently used in 15 counties across the UK, is based on pattern recognition techniques which use neural network technology to identify vehicle number plates.
The new version, claims Racal, combines a number of improved features. With greater memory and faster digital signal processing than its predecessor, Talon provides users with wide colour images of vehicles and their occupants, (from alterative viewpoints when used with multiple cameras). This information can be stored with vehicle data on a secure database.
