Abstract

Method and apparatus for analyzing a status of an object in a predetermined area of a parking lot facility having a plurality of parking spaces. A distinctive marking is projected into at least one predetermined area. An image of the predetermined area, that may include one or more objects, is captured. A three-dimensional model is produced from the captured image. A test is then performed on the produced model to determine an occupancy status of at least one parking space in the predetermined area. An indicating device provides information regarding the determined occupancy status.

Claims

1. A method for analyzing a status of at least one predetermined area of a facility, comprising:

projecting a distinctive marking into at least one predetermined area of the facility;

establishing a baseline by performing an identification procedure on the facility at a predetermined time;

capturing an image of at least one predetermined area of the facility;

producing a three-dimensional model by processing the captured image; and

indicating the status of the at least one predetermined area based upon a comparison of the three-dimensional model to the baseline.

2. The method of claim 1, wherein producing a three-dimensional model further comprises processing the captured image using at least one of a static image process and a dynamic image process.

3. The method of claim 1, wherein indicating the status comprises updating a status display.

4. The method of claim 1, wherein capturing a synchronized image comprises capturing an image with a plurality of sensors.

5. The method of claim 1, wherein capturing a synchronized image comprises capturing an image with a sensor in conjunction with a controllable directional illuminator.

6. The method of claim 1, wherein capturing an image comprises capturing an image with at least one of a direction controlled range-finder and a three-dimensional sensor.

7. The method of claim 1, wherein processing a captured image comprises producing a determination of at least one of a proximity and an orientation of objects in the at least one predetermined area.

8. The method of claim 1, further comprising at least one of recording the captured image and playing back the captured image.

24. The method of claim 1, wherein projecting a marking comprises using a pattern generator to project the distinctive marking at a predetermined wavelength.

9. An apparatus for monitoring a presence of an object in a predetermined space in a parking lot, comprising:

a projecting device that projects a marking into at least one predetermined area of the parking lot;

an image capture device that captures an image representing a predetermined space in the parking lot;

a processor that processes said captured image to produce a three-dimensional model of said captured image, said processor analyzing said three-dimensional model to determine an occupancy condition corresponding to at least one of an empty parking space and an occupied parking space; and

a notification device that provides a notification in accordance with said determined occupancy condition.

10. The apparatus of claim 9, wherein said captured image is processed as at least one of a static image and a dynamic image.

11. The apparatus of claim 9, further comprising a reporting device that provides at least one of a numerical report and a graphical report of a status of said predetermined space in the parking lot.

12. The apparatus of claim 9, wherein said image capture device comprises a plurality of sensors.

13. The apparatus of claim 9, wherein said image capture device comprises a sensor in conjunction with a directional illuminator.

14. The apparatus of claim 9, wherein said image capture device comprises at least one of a directional range-finder sensor and a three-dimensional sensor.

15. The apparatus of claim 9, further comprising a visual display device that provides at least one of a visual representation of the predetermined space and said notification of said occupancy condition.

16. The apparatus of claim 9, wherein said processor determines at least one of a proximity nd an orientation of objects within said predetermined space.

17. The apparatus of claim 9, further comprising a recorder that at least one of records said captured image and plays back said captured image.

18. A method for monitoring a predetermined space in a parking lot, comprising:

projecting a marking into at least one predetermined area of the parking lot;

capturing an image of a predetermined space of the parking lot;

processing the captured image to produce a three-dimensional model of the captured image;

analyzing the three dimensional model to determine an occupancy status of the predetermined space; and

providing a notification when said occupancy status indicates an existence of an unoccupied parking space.

19. The method of claim 18, further comprising providing at least one of a numerical report and a graphical report of a status of the predetermined space in accordance with said parking lot.

20. The method of claim 18, wherein capturing an image comprises capturing an image with a sensor in conjunction with a controllable directional illuminator.

21. The method of claim 18, wherein capturing an image comprises capturing an image with at least one of a directional range-finder sensor and a three-dimensional sensor.

22. The method of claim 20, wherein capturing an image comprises using a plurality of sensors to capture an image of the predetermined space.

23. The method of claim 20, further comprising utilizing the three-dimensional model to perform a parking lot management operation.
