System and method for street-parking-vehicle identification through license plate capturing
First Claim
1. A method for identifying a vehicle in a parking area, the method comprising:
- receiving video data in a sequence of frames provided by an associated video capture device observing a parking area from a first field of view over a duration of time;
receiving image data from an associated image capture device observing the street traffic from a second field of view at least partially overlapping the first field of view;
determining a presence of a vehicle in the parking area by identifying an object in motion in the video data;
tracking a location of a vehicle across the sequence of frames, wherein the tracking;
comparing a select frame captured by the associated video capture device with an image captured by the associated image capture device;
based on the comparing, matching the vehicle in the image with the vehicle in the frame; and
,determining a license plate number of the vehicle by locating a license plate on the vehicle in the image.

Abstract
A method and a system for identifying a vehicle in a parking area includes receiving video data from a video camera observing a parking area from a first field of view over duration of time and receiving image data from a still camera observing a second field of view overlapping the first field of view. The method includes tracking a location of a vehicle across a sequence of frames. The tracking includes determining a time instant at which each frame was captured. The method includes comparing a select frame captured by the video camera with an image captured by the still camera. Based on the comparing, the method includes matching the vehicle in the image with the vehicle in the frame. The method includes determining a license plate number of the vehicle by locating a license plate on the vehicle in the image.

14. A system for identifying a vehicle in a parking area, the system comprising:
-
a video buffer module adapted to receive video data in a sequence of frames provided by an associated video capture device observing a parking area from a first field of view over a duration of time; an image buffer module adapted to receive image data from an associated image capture device observing the parking area from a second field of view at least partially overlapping the first field of view; a vehicle detection module adapted to determine a presence of a vehicle captured by identifying an object in motion in the video data; a vehicle tracking module adapted to track a location of the vehicle across the sequence of frames; and
,a vehicle identification module adapted to; compare a select frame captured by the associated video capture device with an image captured by the associated image capture device, match the vehicle in the image with the vehicle in the frame, and determine a license plate number of the vehicle by locating a license plate on the vehicle in the image, a processor adapted to implement the modules. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)
