SYSTEM AND METHOD FOR SENSOR POSITIONING AND VEHICLE TRACKING USING LPR BASED SPATIAL CONSTRAINTS

摘要

The invention provides methods and systems for identifying objects transitioning boundaries defined around geographic areas using sensors. Objects that are vehicles are detected by license plate reader sensors. Boundaries defining geographic zones and sub-zones are pre-defined graphically by reference to a map or computed based on locations of sensors located within the geographic region. When sensor coverage is incomplete, soft zones are computed and defined. Soft zones are computed using probabilistic models, and are developed to minimize the number of escape paths from any sub-zone around sensor locations. Using these probabilistic models, additional sensors can be optimally placed for further enhancement of the detection system.
