Abstract

A system is provided for processing images of wayside equipment adjacent to a route. The system includes a video camera configured to collect visible spectral data of the wayside equipment. The video camera is positioned on an external surface of a powered system traveling along the route. Additionally, the system includes a controller coupled to the video camera, where the controller is configured to process the visible spectral data, and is further configured to transmit a signal based upon processing the visible spectral data. Additionally, a method and computer readable media are provided for processing images of wayside equipment adjacent to a route.

Claims

1. A system for processing images of wayside equipment adjacent to a route, said system comprising:

a camera configured to collect visible spectral data of said wayside equipment, said video camera positioned on an external surface of a powered system traveling along said route; and

a controller coupled to said camera, said controller configured to process said visible spectral data, said controller being configured to transmit a signal based upon processing said visible spectral data, said signal being used to control an operational condition of the powered system.

2. The system of claim 1, wherein said powered system is one of an off-highway vehicle, a marine propulsion vehicle, and a rail vehicle.

3. The system of claim 2, wherein said powered system is a rail vehicle traveling along a railroad, said wayside equipment is one of a light signal and a track number indicator.

4. The system of claim 3, wherein said video camera is configured to process pixels within an adjustable field of view, said adjustable field of view being adjusted to coincide with said wayside equipment.

5. The system of claim 4, wherein said controller includes a memory configured to store at least one expected position of said wayside equipment along said railroad.

6. The system of claim 5, further comprising a position determination device to determine a position of said locomotive along said railroad, said video camera being configured to collect said visible spectral data of said wayside equipment positioned at said expected position.

7. The system of claim 6, wherein said field of view is adjusted to collect said visible spectral data of said wayside equipment positioned at said expected position.

8. The system of claim 5, further comprising a position determination device to determine a position of said locomotive along said railroad, said memory being configured to further store at least one position parameter of said wayside equipment at each expected position.

9. The system of claim 8, wherein said field of view is adjusted based upon said at least one stored position parameter to collect said visible spectral data of said wayside equipment positioned at said expected position.

10. The system of claim 8, wherein said controller is configured to align said video camera with said wayside equipment at each expected position based upon said at least one position parameter.

11. The system of claim 10, wherein said at least one position parameter comprises at least one of a perpendicular distance from a ground portion to said wayside equipment and a distance from a portion of said railroad to said ground portion.

12. The system of claim 5, wherein said wayside equipment is a light signal, said memory is further configured to store an expected color of said light signal positioned at said expected position.

13. The system of claim 12, wherein said memory is further configured to store an expected profile of a light signal frame at said expected position and is further configured to store an expected position of said light signal having said expected color along said light signal frame.

14. The system of claim 12, wherein said signal is based upon said expected color, said signal from said controller configured to switch said locomotive into one of a motoring mode and a braking mode, said motoring mode being an operating mode in which energy from one of a locomotive engine and an energy storage device is utilized in propelling said locomotive along said railroad, said braking mode being an operating mode in which energy from one of a locomotive engine and locomotive braking system is stored in said energy storage device.

15. The system of claim 4, wherein said wayside equipment is a light signal, said video camera is configured to process a plurality of frames of said light signal to determine if said light signal is in one of a flashing mode and non-flashing mode.

16. The system of claim 15, wherein said light signal being in said flashing mode is indicative of a particular upcoming condition along said railroad.

17. The system of claim 4, wherein said locomotive includes a single operator.

18. A method for processing images of wayside equipment adjacent to a route, said method comprising:

collecting visible spectral data of said wayside equipment with a video camera positioned on an external surface of a powered system traveling along said route;

processing said visible spectral data with a controller coupled to said video camera; and

transmitting a signal from said controller based upon said processing of said visible spectral data.

19. The method of claim 18, wherein said powered system is one of an off-highway vehicle, a marine propulsion vehicle, and a rail vehicle.

20. The method of claim 19, wherein said powered system is a rail vehicle traveling along a railroad, said wayside equipment is one of a light signal and a track number indicator.

21. The method of claim 20, wherein said processing said visible spectral data comprises processing pixels within an adjustable field of view of said video camera, said adjustable field of view being adjusted to coincide with said wayside equipment.

22. The method claim 21, further comprising storing at least one expected position of said wayside equipment along said railroad within a memory of said controller.

23. The method of claim 22, further comprising:

determining a position of said locomotive along said railroad; and

collecting said visible spectral data of said wayside equipment positioned at said expected position.

24. The method of claim 22, further comprising:

determining a position of said locomotive along said railroad; and

storing at least one position parameter of said wayside equipment at each expected position within said memory.

25. The system of claim 24, further comprising adjusting said field of view based upon said at least one stored position parameter to collect said visible spectral data of said wayside equipment positioned at said expected position.

26. Computer readable media for processing images of wayside equipment adjacent to a railroad, wherein visible spectral data of said wayside equipment is collected with a video camera upon positioning the video camera on an external surface of a locomotive traveling along said railroad, said computer readable media comprising:

a computer program code for processing said visible spectral data with a controller coupled to said video camera; and

a computer program code for transmitting a signal from said controller based upon said processing of said visible spectral data.
