SYSTEM AND METHOD FOR AVAILABLE PARKING SPACE ESTIMATION FOR MULTISPACE ON-STREET PARKING
First Claim
1. A method for determining parking availability, the method comprising:
- receiving video data from a sequence of frames taken from an associated image capture device monitoring a parking area;
estimating a background image associated with a current frame;
determining a foreground image from the background image and the current frame;
determining a length of a parking space between adjacent vehicles in the foreground image.

Abstract
A method for determining parking availability includes receiving video data from a sequence of frames taken from an image capture device that is monitoring a parking area. The method includes determining background and foreground images in an initial frame of the sequence of frames. The method further includes updating the background and foreground images in each of the sequence of frames following the initial frame. The method also includes determining a length of a parking space using the determined background and foreground images. The determining includes computing a pixel distance between a foreground image and one of an adjacent foreground image and an end of the parking area. The determining further includes mapping the pixel distance to an actual distance for estimating the length of the parking space.

19. A system for determining parking availability, the system comprising:
a parking space determination device, the parking space determination device including; a video capture module adapted to receive image data corresponding to a sequence of frames each capturing a parking area over a duration of time; a stationary vehicle detection module adapted to detect a parked vehicle in the parking area as a change between a select frame and a background; a background updating module adapted to estimate the background at a given instant of time by applying a predetermined updating factor in a process used to determine the background in each select frame; a distance calculation module adapted to calculate an actual distance between the parked vehicle and one of an adjacent parked vehicle and a boundary of the parking area; and
,a processor adapted to implement the modules. - View Dependent Claims (20, 21)
