Definitions

  • the present invention relates to car park systems that apply visual recognition of a vehicle's license plate characters for entry or exit.
  • this invention relates to a car park system and method for facilitating entry and exit.
  • Car park systems that apply visual recognition of a vehicle' s license plate characters to compute parking fees are known.
  • one or more cameras capture an image of the license plate characters during entry to the parking areas of a car park system. The image is then converted to data for storage and subsequent processing. Upon capture of the image, entry to the parking areas is permitted.
  • other information such as, for example, date and time of the vehicle's entry is also noted during entry. Such other information is then stored in association with the license plate characters.
  • Payment collection includes, for example, a human operator or automated collecting devices. Such automated collecting devices include cash collecting machines, or a credit or cash card reader.
  • the failure to recognize the license plate characters may be due to faults in the cameras or when the license plate characters are not recognizable by the cameras. Instances of the latter situation occur, for example, when the license plate characters are obstructed from view. Unrecognized license plate characters also occur when a license plate is missing or when one or more of the license plate characters are damaged. Consequently, the vehicle may not enter the parking areas if the license plate characters are not recognized.
  • recognition of the license plate characters during entry to the parking areas does not guarantee that the license plate characters can be recognized for exit. This is because the license plate characters also have to be recognized at an exit to compute parking fees. Hence, the failure to recognize the license plate characters may occur at the exit even though entry to the parking areas was permitted or even after payment for parking fees of a vehicle has been made prior to the vehicle moving to the exit.
  • the present invention seeks to provide a car park system and method for facilitating entry to and exit from parking areas of the car park system.
  • the present invention provides a car park system comprising: an image system for capturing and processing an image of license plate characters of a vehicle at an entry to parking areas of the car park system;
  • an entry system coupled to the image system to receive a license plate signal from the image system, the entry system being associated with the entry and having: a movable entry barrier; one or more entry detectors for detecting the vehicle at one or more predetermined areas of the entry; a ticket generator; and an entry controller for controlling the movable entry barrier, the entry controller being coupled to the movable entry barrier, at least one of the entry detectors and the ticket generator, the entry controller having storage means for storing an entry list of license plate characters;
  • the present invention provides a car park system comprising: an image system for capturing and processing an image of license plate characters of a vehicle at an exit from parking areas of the car park system; and an exit system coupled to the image system, the exit system being associated with the exit and having: a movable exit barrier; a ticket reader for reading a ticket when the ticket is presented by a user of the vehicle; one or more exit detectors for detecting the vehicle at one or more predetermined areas of the exit; and an exit controller for controlling the movable exit barrier, the exit controller being coupled to the movable exit barrier, at least one of the exit detectors and the ticket reader, the exit controller having storage means for storing an exit list of license plate characters.
  • the present invention provides a method for facilitating entry to and exit from parking areas of a car park system, the method comprising the steps of: capturing, with an image system, an image of license plate characters of a vehicle when the vehicle is detected at a predetermined area of an entry to the parking areas; processing the image to provide the license plate characters to an entry controller; and determining, by the entry controller, whether the vehicle requires a ticket from a ticket generator to enter the parking areas based upon an entry list of license plate characters.
  • the present invention provides a method for facilitating exit from parking areas of a car park system, the method comprising the steps of: capturing, with an image system, an image of license plate characters of a vehicle when the vehicle is detected at a predetermined area of an exit of the parking areas; processing the image to provide the license plate characters to an exit controller; and determining, by the exit controller, whether the vehicle requires a ticket to exit the parking areas based upon an exit list of license plate characters.

  • details are provided to describe the preferred embodiment. It shall be apparent to one skilled in the art, however, that the invention may be practiced without such details. Some of these details may not be described at length so as not to obscure the invention.
  • One advantage of the invention is that the car park system distinguishes between users who pre-pay for long term parking and other users who are paying for parking based on parking duration within a single day. Accordingly, tickets are only generated for the latter category of users at entries to parking areas of the car park system.
  • the car park system facilitates exit of vehicles using the car park system.
  • An exit controller associated with an exit of the car park system, stores an exit list of license plate characters. The license plate characters of any vehicle wishing to exit from the parking areas are checked against this exit list. If found in the exit list, the exit controller permits such a vehicle to exit without having to present a ticket even though such a ticket is available.
  • a further advantage of the invention is that the car park system facilitates use of the car park system for pre-designated vehicles.
  • pre-designated vehicles can be recognized during entry or exit to enable, for example, a waiver or a discount of parking fees.
  • Yet another advantage of the invention is that the car park system enables license plate characters of vehicles to be verified for users who lose their parking tickets. Verification of the license plate characters enables the car park system to compute parking fees correctly for such vehicles. Verifying and computing the parking fees of such vehicles alleviates fraudulent claims such as, for example, when a parking ticket is not lost but the penalty for losing the parking ticket is less than the parking fees required.
