Abstract

A system and method are configured to provide a cost-effective runway monitoring tool that may be used by airports to aid in accident avoidance and investigation by generating and analyzing image data corresponding to runway areas and surfaces.

Claims

1. A system for monitoring at least one runway area to produce runway condition data, the system comprising:

at least one monitoring device configured to monitor at least one runway area and generate image data pertaining to the at least one runway area;

at least one transceiver coupled to the at least one monitoring device and configured to receive image data from the at least one monitoring device; and

at least one processor configured to communicate with the at least one transceiver to receive image data and generate data indicating at least one runway condition, wherein

the at least one transceiver is configured to receive operation instruction data from the at least one processor and transmit image data to the at least one processor via at least one communication link,

the at least one monitoring device is one of a plurality of monitoring devices and the at least one transceiver is one of a plurality of transceiver configured to receive operation instruction data from the at least one processor and transmit image data to the at least one processor via at least one communication link,

the plurality of monitoring devices are located at individual locations to monitor each other by providing views that cover at least one other monitoring device,

the at least one processor is configured to issue an alert in response to a determination that the at least one runway area includes at least one of potentially hazardous foreign object debris, vehicle congestion and hazardous runway conditions, and

the alert changes the color of runway lights or flashes runway lights.

2. The system of claim 1, further comprising at least one interface coupled to the at least one processor and configured to output the data indicating at least one runway condition.

3. The system of claim 1, wherein analysis of image data is performed in real-time.

4. The system of claim 1, wherein the processor performs image data processing in real-time.

5. The system of claim 1, further comprising data storage equipment coupled to the processor and configured to store at least one of the transmitted image data and the data indicating the at least one runway area condition.

6. The system of claim 1, wherein the image data indicates at least one of runway area activity and runway area condition.

7. The system of claim 1, wherein the at least one runway area includes at least one of a runway, taxiway, approach airspace and takeoff airspace.

8. The system of claim 1, wherein the data indicating the at least one runway condition data is output to a data feed accessible by at least one vehicle.

9. The system of claim 1, wherein the data indicating at least one runway area condition is output to a groundstation.

10. The system of claim 1, wherein the at least one monitoring device includes at least one of a video camera, single-frame camera, infrared camera, high definition camera, Light Detection and Ranging device.

11. The system of claim 1, wherein the plurality of monitoring devices are located at individual locations and at different elevations along the at least one runaway area to provide coverage of the entirety of the at least one runaway area.

12. The system of claim 1, wherein the at least one monitoring device generates baseline image data associated with a first condition, generates other image data associated with at least a second condition and the at least one processor compares the image data associated with the conditions to determine whether foreign object debris is present in the at least one runway area.

13. The system of claim 1, wherein the at least one monitoring device generates baseline image data associated with a first condition, generates other image data associated with at least a second condition and the at least one processor compares the image data associated with the conditions to determine whether vehicle traffic congestion is within acceptable tolerances.

14. The system of claim 13, wherein the tolerances are predetermined and accessible by the at least one processor prior to generation of the image data associated with at least the second condition.

15. The system of claim 1, wherein the processor may issue instructions to generate an alert if the data indicating the at least one runway condition indicates an unacceptable runway area condition.

16. The system of claim 15, wherein the unacceptable runway condition may include at least one of, vehicle traffic congestion outside acceptable tolerances, presence of an unacceptable amount of ice, presence of fire, and presence of foreign object debris.

17. A method for monitoring at least one runway area to produce runway condition data based on the monitoring, the method comprising:

monitoring at least one runway area and generating image data pertaining to the at least one runway area using a plurality of monitoring devices each located at individual locations to monitor the at least one runway area and each other by providing views that cover at least one other monitoring device;

transmitting at least a portion of the image data to a processor;

analyzing the transmitted image data, via the processor, to generate data indicating at least one runway area condition;

issuing an alert in response to a determination that the at least one runway area includes at least one of potentially hazardous foreign object debris, vehicle congestion and hazardous runway conditions; and

issuing instructions to generate an alert if the data indicating the at least one runway condition indicates an unacceptable runway area condition, wherein the alert changes the color of runway lights or flashes runway lights.

18. The method of claim 17, further comprising storing at least one of the transmitted image data and the at least one runway area condition in data storage equipment.

19. The method of claim 17, monitoring is performed in real-time.

20. The method of claim 17, analysis of image data is performed in real-time.

21. The method of claim 17, wherein the at least one runway area includes at least one of a runway, taxiway, approach airspace and takeoff airspace.

22. The method of claim 17, further comprising outputting the data indicating the at least one runway condition.

23. The method of claim 17, further comprising storing at least one of the transmitted image data and the data indicating the at least one runway area condition.

24. The method of claim 17, wherein the image data indicates at least one of runway area activity and runway area condition.

25. The method of claim 17, wherein the at least one runway area includes at least one of a runway, taxiway, approach airspace and takeoff airspace.

26. The method of claim 17, further comprising outputting the data indicating the at least one runway condition data to a data feed accessible by at least one vehicle.

27. The method of claim 17, further comprising outputting the data indicating the at least one runway area condition to a groundstation.

28. The method of claim 17, further comprising:

generating baseline image data associated with a first condition;

generating other image data associated with at least a second condition; and

comparing the image data associated with the conditions to determine whether foreign object debris is present in the at least one runway area.

29. The method of claim 17, further comprising:

generating baseline image data associated with a first condition;

generating other image data associated with at least a second condition; and

comparing the image data associated with the conditions to determine whether vehicle traffic congestion is within acceptable tolerances.

30. The method of claim 29, wherein the tolerances are predetermined prior to generation of the image data associated with at least the second condition.

31. The method of claim 17, wherein the unacceptable runway condition may include at least one of, vehicle traffic congestion outside acceptable tolerances, presence of an unacceptable amount of ice, presence of fire, and presence of foreign object debris.
