Abstract

A method can include generating image data of an interior of a fuel tank disposed within a wing of an aircraft, and determining, by a processing device, an amount of wing bending of the wing of the aircraft based on the generated image data of the interior of the fuel tank. The method can further include producing, by the processing device, a fuel measurement value representing an amount of fuel contained in the fuel tank based on the amount of wing bending of the wing of the aircraft, and outputting, by the processing device, an indication of the fuel measurement value.

Claims (73)

producing, by the processing device, a fuel measurement value representing an amount of fuel contained in the fuel tank based on the amount of wing bending of the wing of the aircraft; and

outputting, by the processing device, an indication of the fuel measurement value.

2. The method of claim 1 ,

wherein determining the amount of wing bending comprises:

determining, based on the active image data and the reference image data, a displacement of one or more physical features of the interior of the fuel tank; and

determining the amount of wing bending based on the determined displacement of the one or more physical features.

3. The method of claim 1 ,

wherein producing the fuel measurement value comprises:

adjusting a model of a shape of the fuel tank based on the determined amount of wing bending; and

producing the fuel measurement value based on the adjusted model of the shape of the fuel tank.

4. The method of claim 3 ,

wherein producing the fuel measurement value representing the amount of fuel contained in the fuel tank based on the adjusted model of the shape of the fuel tank comprises:

identifying, based on the generated active image data, a location of the interior of the fuel tank corresponding to an interface of fuel and ullage within the interior of the fuel tank;

identifying a location of an intersection of the interface of fuel and ullage with one or more physical features identified in the adjusted model of the fuel tank; and

determining a volume of fuel contained within the fuel tank based on the identified location of the intersection of the interface of fuel and ullage with the one or more physical features identified in the adjusted model of the fuel tank.

5. The method of claim 1 ,

wherein generating the active image data of the interior of the fuel tank comprises generating the active image data using one or more image capturing devices located to generate the active image data of the interior of the fuel tank.

6. The method of claim 5 ,

wherein the one or more image capturing devices comprise a plurality of image capturing devices disposed at a plurality of locations to include a plurality of fields of view of the interior of the fuel tank.

7. A device comprising:

at least one processor; and

computer-readable memory encoded with instructions that, when executed by the at least one processor, cause the device to:

receive reference image data of an interior of a fuel tank disposed within a wing of an aircraft;

receive active image data of the interior of the fuel tank generated when the fuel tank contains fuel;

determine an amount of wing bending of the wing of the aircraft based on the received active image data and the reference image data of the interior of the fuel tank;

produce a fuel measurement value representing an amount of fuel contained in the fuel tank based on the amount of wing bending of the wing of the aircraft; and

output the fuel measurement value.

8. The device of claim 7 ,

wherein the computer-readable memory is further encoded with instructions that, when executed by the at least one processor, cause the device to determine the amount of wing bending by at least causing the device to:

determine, based on the active image data and the reference image data, a displacement of one or more physical features of the interior of the fuel tank; and

determine the amount of wing bending based on the determined displacement of the one or more physical features.

9. The device of claim 7 ,

wherein the computer-readable memory is further encoded with instructions that, when executed by the at least one processor, cause the device to produce the fuel measurement value by at least causing the device to:

adjust a model of a shape of the fuel tank based on the determined amount of wing bending; and

produce the fuel measurement value based on the adjusted model of the shape of the fuel tank.

10. The device of claim 9 ,

wherein the computer-readable memory is further encoded with instructions that, when executed by the at least one processor, cause the device to produce the fuel measurement value representing the amount of fuel contained in the fuel tank based on the adjusted model of the shape of the fuel tank by at least causing the device to:

identify, based on the received active image data, a location of the interior of the fuel tank corresponding to an interface of fuel and ullage within the interior of the fuel tank;

identify a location of an intersection of the interface of fuel and ullage with one or more physical features identified in the adjusted model of the fuel tank; and

determine a volume of fuel contained within the fuel tank based on the identified location of the intersection of the interface of fuel and ullage with the one or more physical features identified in the adjusted model of the fuel tank.

11. The device of claim 7 ,

wherein the computer-readable memory is further encoded with instructions that, when executed by the at least one processor, cause the device to receive the active image data of the interior of the fuel tank by at least causing the device to receive the active image data from one or more image capturing devices located to generate the active image data of the interior of the fuel tank.

12. A system comprising:

one or more image capturing devices located to generate:

reference image data of an interior of a fuel tank disposed within a wing of an aircraft; and

active image data of the interior of the fuel tank when the fuel tank contains fuel;

at least one processor; and

computer-readable memory encoded with instructions that, when executed by the at least one processor, cause the system to:
