Abstract

A parking lot information system comprising a digital camera for obtaining an image of parking spaces in the parking lot where each parking space is marked with a visual identifier, a computer coupled to the digital camera for identifying available parking spaces by recognizing the identifiers marking the available parking spaces, and a display coupled to the computer for displaying information on the available parking spaces.

Claims

1. A parking lot information system, comprising:

a plurality of parking spaces in a parking lot;

a digital camera for obtaining images of the parking spaces in the parking lot;

a computer coupled to the digital camera for detecting vehicles in specific ones of the parking spaces from the images;

the computer coupled to the display camera for;

detecting unique vehicle identifiers from the images for vehicles occupying the parking spaces;

indexing the unique vehicle identifiers to the parking spaces by using a mirror arrangement within each of the parking spaces, wherein the mirror arrangement reflects an image of a license plate of a vehicle parked in a corresponding parking space to the digital camera, and wherein the mirror arrangement is associated with a visual identifier of the parking space;

responding to inquiries from remote devices, said inquiries being inquiries for specific ones of the vehicles occupying the parking spaces and for one or more available parking spaces, wherein the responding conveys messages providing parking location information to requestors; and

allowing a requestor to select one of the available parking spaces.

2. The parking lot information system of claim 1, wherein the unique vehicle identifiers are license plate numbers.

3. The parking lot information system of claim 1, wherein the computer is further for:

upon user request, providing images of user selected ones of the vehicles occupying the parking spaces for any durations that the vehicles are parked in the parking lot.

4. The parking lot information system of claim 1, wherein the computer is further for:

upon user request, providing real time video images showing vehicle owners a user requested one of the vehicles that are parked in the parking lot.

5. The parking lot information system of claim 1, wherein the computer is further for:

upon user request, providing location instructions to vehicle owners to aid owners in finding where a requested one of the vehicles is parked within the parking lot.

6. The parking lot information system of claim 1, wherein the computer is further for:

providing messages to mobile devices of vehicle owners, said messages comprising status and change of status information regarding the vehicles in the parking lot while the vehicles are parked in the parking lot.

7. The parking lot information system of claim 1, wherein the computer is further for:

identifying available parking spaces by recognizing the identifiers marking the available parking spaces.

8. A method comprising:

a computing device detecting unique vehicle identifiers and unique parking identifiers from images of vehicles occupying parking spaces;

the computing device indexing to the unique parking identifiers to the unique parking identifiers for the parking spaces by using a mirror arrangement within each of the parking spaces, wherein the mirror arrangement reflects an image of a license plate of a vehicle parked in a corresponding parking space to the digital camera, and wherein the mirror arrangement is associated with a visual identifier of the parking space; and

the computing device responding to inquiries from remote devices, said inquiries being inquiries for specific ones of the vehicles occupying the parking spaces, wherein the responding conveys messages providing parking location information to requestors.

9. The method of claim 8, wherein the unique vehicle identifiers are license plate numbers.

10. The method of claim 8, further comprising:

a set of cameras monitoring the parking spaces of the parking lot, wherein the computing device analyzes images from the cameras and utilizing optical character recognition to determine the unique vehicle identifier.

11. The method of claim 8, further comprising:

the computing device, upon user request, providing images of user selected ones of the vehicles occupying the parking spaces for any durations that the vehicles are parked in the parking lot.

12. The method of claim 8, further comprising:

the computing device upon user request, providing real time video images showing vehicle owners a user requested one of the vehicles that are parked in the parking lot.

13. The method of claim 8, further comprising:

the computing device upon user request, providing location instructions to vehicle owners to aid owners in finding where a requested one of the vehicles is parked within the parking lot.

14. The method of claim 8, further comprising:

the computing device providing messages to mobile devices of vehicle owners, said messages comprising status and change of status information regarding the vehicles in the parking lot while the vehicles are parked in the parking lot.

15. The method of claim 8, further comprising providing a mirror arrangement to reflect images of vehicle'"'"'s license plates to a set of cameras, wherein the unique vehicle identifiers are numbers from the license plates detected by performing optical character recognition using the reflected images.

16. A computer program product comprising a non-transitory computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising:

computer readable program code, stored on the non-transitory computer readable storage medium, configured to detect unique vehicle identifiers and unique parking identifiers from images of vehicles occupying parking spaces;

computer readable program code, stored on the non-transitory computer readable storage medium, configured to index the unique vehicle identifiers to the unique parking identifiers for the parking spaces by using a mirror arrangement within each of the parking spaces, wherein the mirror arrangement reflects an image of a license plate of a vehicle parked in a corresponding parking space to the digital camera, and wherein the mirror arrangement is associated with a visual identifier of the parking space; and

computer readable program code, stored on the non-transitory computer readable storage medium, configured to respond to inquiries from remote devices, said inquiries being inquiries for specific ones of the vehicles occupying the parking spaces, wherein responding conveys messages providing parking location information to requestors.

17. The computer program product of claim 16, wherein the unique vehicle identifiers are license plate numbers.

18. The computer program product of claim 16, further comprising:

computer readable program code configured to monitoring the parking spaces of the parking lot using images from a set of cameras, wherein the computer readable program code configured to analyze images from the cameras and utilizing optical character recognition to determine the unique vehicle identifier.

19. The computer program product of claim 16, further comprising:

computer readable program code configured to, upon user request, provide images of user selected ones of the vehicles occupying the parking spaces for any durations that the vehicles are parked in the parking lot.

20. The computer program product of claim 16, further comprising:

computer readable program code configured to, upon user request, provide location instructions to vehicle owners to aid owners in finding where a requested one of the vehicles is parked within the parking lot.
