Konnet Vian’s Automatic Number Plate Recognition (ANPR) engine is a software module that detects, scans, reads and converts a vehicle’s registration number into text form. Applications developed using this technology save the ANPR data in a database with a date/time stamp along with the corresponding video footage. ANPR can be implemented at traffic signals, toll booths, parking spaces, accident prone areas, security sensitive regions and many more. It can help track licence defaulters, number plate offences, accidental offences, red light violations, real-time exemption/detention, crime pattern analyses and more.
