System and method of vehicle surveillance
View Patent ↗The invention relates to a system and method of conducting surveillance of stolen vehicles. Stolen vehicle information is downloaded from a database to a central server. At the central server, vehicle information is parsed to the specific requirements. Each subscribing jurisdiction downloads its area-specific stolen vehicle database to a subscriber workstation, e.g., via the Internet or an intranet. Police cars have on-board mobile surveillance points having a camera and a processor. A copy of the area-specific stolen vehicle database is loaded into each car's processor. The mobile surveillance point reads license plates of vehicles in traffic, and the processor compares the license plates to stolen plate numbers stored in the database. The processor activates a signal to alert the officer. Stationary checkpoints located in the jurisdiction have a stationary surveillance point having a camera and a processor. The surveillance system stores images and creates a database of all vehicle plates in the area. The surveillance data is downloaded to the subscriber computer. The subscriber computer has a map database. A comparison algorithm identifies stolen vehicles in the area and their direction of travel, and displays the information on an area map. The analysis if performed with a spatial analysis algorithm along with temporal analysis using police officer's experience and knowledge of the area and vehicle types (make/model/value/etc) stolen. The police officer analyzes patterns of stolen vehicles and generates suggested new locations for checkpoints, narrowing in on a possible chop shop location.
1. A method of identifying a region associated with a pattern of activity of interest using a plurality of electronic vehicle surveillance points comprising the steps of:
capturing images of license plates of a plurality of different vehicles at two or more of said plurality of surveillance points;
recording data associated with each captured image;
extracting alphanumeric license plate data from said captured images;
comparing said license plate data to a database of license plates to identify a plurality of different vehicles of interest; and
performing spatial analysis on said plurality of different vehicles of interest and recorded data associated with each of said different vehicles of interest to identify region associated with a pattern of activity of interest involving said plurality of different vehicles of interest.
2. A method of identifying a region associated with a pattern of activity of interest according to claim 1 , further comprising the steps of:
repositioning at least one of said surveillance points closer to said region associated with said pattern of activity;
capturing images of a plurality of license plates of different vehicles at said at least one repositioned surveillance point and at least one other of said surveillance points;
recording data associated with each captured image;
extracting alphanumeric license plate data from said captured images;
comparing said license plate data to a database of license plates to identify a second plurality of vehicles of interest; and
performing spatial analysis on said second plurality of vehicles of interest and recorded data associated with said captured images of license plates of said second plurality of vehicles of interest to identify a second region associated with said pattern of activity of interest, said second region being smaller than said first region.
3. A method of identifying a region associated with a pattern of activity of interest according to claim 1 , wherein said activity of interest comprises operation of a chop shop.
4. A method of identifying a region associated with a pattern of activity of interest according to claim 1 , wherein said license plate matches of interest comprise license plates associated with stolen vehicles.
5. A method of identifying a region associated with a pattern of activity of interest according to claim 1 , wherein at least of said plurality of surveillance points comprises a mobile surveillance point.
6. A method of identifying a region associated with a pattern of activity of interest according to claim 5 , further comprising the step of:
displaying data associated with a license plate match of interest in said mobile surveillance point.
7. A method of identifying a region associated with a pattern of activity of interest according to claim 1 , wherein recorded data comprises a time associated with each captured image.
8. A method of identifying a region associated with a pattern of activity of interest according to claim 1 , wherein said recorded data comprises a direction of travel associated with each captured image.
