VIDEO-BASED SYSTEM AND METHOD FOR DETECTING EXCLUSION ZONE INFRACTIONS
First Claim
1. A method for determining a parking violation, the method comprising:
- receiving video data as a sequence of frames provided by an associated image capture device;
defining a location of an exclusion zone in the video data;
detecting a vehicle located in the defined exclusion zone; and
,determining a duration that the detected vehicle is in the exclusion zone based on a number of the sequence of frames including the detected vehicle.

Abstract
A method for determining a parking violation includes receiving video data as a sequence of frames provided by a camera. The method includes defining a location of an exclusion zone in the video data. The method includes detecting a vehicle located in the defined exclusion zone. The detecting includes determining a background in an initial frame of the video data and determining a background in a select frame by applying a predetermined updating process. The detecting includes subtracting the background of the select frame from the initial frame to obtain an image difference. The detecting includes classifying the pixels in the image difference as foreground or background pixels and classifying the pixels in the foreground image as vehicle or non-vehicle pixels. The method includes determining a duration that the detected vehicle is in the exclusion zone based on a number of the sequence of frames including the detected vehicle.

16. A system for determining a parking violation, the system comprising a parking violation determination device in communication with an associated image capture device adapted to monitor an exclusion zone over a duration of time, the parking violation determination device including:
-
a video capture module adapted to receive video data from the associated image capture device and corresponding to a sequence of frames each capturing the exclusion zone; an exclusion zone detection module adapted to define a location of the exclusion zone in the video data; a vehicle detection module adapted to detect a vehicle located in the defined exclusion zone; a duration determination module adapted to determine a duration that a vehicle is in the exclusion zone based on a number of the sequence of frames including the vehicle pixels; and
,a processor adapted to implement the modules. - View Dependent Claims (17, 18, 19, 20, 21, 22)
