METHOD OF DETERMINING A LICENSE PLATE OF A VEHICLE TRACKED BY A SURVEILLANCE SYSTEM

摘要

A vehicle is tracked by a VMD -equipped video surveillance system as the vehicle travels along a roadway. ALPR cameras are deployed at one or more points along the roadway. Detection zones are defined in the surveillance system corresponding to target areas of the ALPR cameras. Detection zones may also be defined for areas designating for pay parking. A server receives detection events when vehicles enter or exit a detection zone. The server also receives LPR events when ALPR cameras capture vehicle license plates. Optionally the server receives mobile phone tracking data. The server correlates the time and location of detection events with LPR events and optionally mobile phone tracking events in order to associate a license plate number, and optionally a mobile phone, to a tracked vehicle. The server may also calculate the parking fee and generate a parking bill.
