Abstract

A parking advisor images scenes of a parking area and identifies free spaces using image processing techniques. The advisor then makes recommendations as to which areas a driver should go based on the locations of free spaces. One way of outputting the recommendations is to display them on a terminal at an entry gate or to print them on a ticket, receipt, or other piece of paper. An entry terminal may be provided to allow the user to enter a preferred destination served by the parking area. For example, the destination could be a particular airline terminal or department store. The advisor may select, among the free spaces identified, those that are most convenient to the destination and provide corresponding directions.

Claims

1. A method for assisting a user in finding a parking space, said method comprising the steps:

imaging at least one scene of a parking venue to produce at least one image;

receiving destination data at a terminal;

calculating, from a result of said imaging, a location of at least two open spaces and calculating an optimal path including at least one of said at least two open spaces to a destination corresponding to said destination data; and

outputting at said terminal an indication of said result of said step of calculating.

2. The method as claimed in claim 1, wherein said step of calculating includes the step:

calculating a least-cost path through said destination.

3. The method as claimed in claim 2, wherein said step of calculating a least-cost path includes the steps:

calculating vehicle flow from a result of said imaging; and

basing said least-cost path on said vehicle flow.

4. The method as claimed in claim 1, wherein said step of outputting includes generating a map.

5. The method as claimed in claim 1, wherein said step of generating includes generating an output at a fixed terminal.

6. A parking advisor comprising:

means for generating image data corresponding to multiple scenes of a parking area; and

a controller having an input for receiving said image data, said controller comprising;

means for determining portions of said parking area containing free parking spaces in response to said image data;

a further input for receiving destination data indicating a destination from a user; and

means for calculating and outputting an indication of an optimum route to said portions of said parking area and to said destination.

7. The parking advisor as claimed in claim 6, wherein said indication includes a map.

8. The parking advisor as claimed in claim 6, wherein said indication includes a text or audio message indicating optimum route.

9. A method for recommending areas of free parking in a parking facility, said method comprising the steps:

receiving image data responsive to a scene of a parking area;

detecting locations of free parking spaces in response to said image data;

receiving data indicating a destination;

determining optimal ones of said free parking spaces responsive to said destination in response to said destination and said detected locations of free parking spaces; and

outputting a map responsive said step of determining, said map indicating where said optimal ones of said free parking spaces may be found in dependence on said destination.

10. The method as claimed in claim 9, wherein said step of outputting a map includes generating a wireless signal readable by a portable terminal.
