Abstract

Present novel and non-trivial system, device, and method for generating a steering command for at least one forward-looking image capture device are disclosed. The steering command generating system is comprised of a source of navigation data, an avionics system processor (“ASP”) configured to receive the navigation data representative of a wind correction angle (“WCA”); generate steering data as a function of at least the navigation data and representative of a steering command commensurate to an angular difference; and provide the steering data to one or more forward-looking image capture device(s). In another embodiment, the ASP may further receive motion tracking data representative of a head position angular measurement and include the motion tracking data in the function for generating steering data. The angular difference may correspond to the WCA or the measurement of a head position angle.

First claim

What is claimed is:

1. A system for generating a sensor steering command for at least one forward-looking image capture device, comprising:
a source of motion tracking data representative of information corresponding to a first angular measurement of head position of a pilot inside an aircraft;
a source of navigation data representative of information corresponding to a second angular measurement between aircraft heading and aircraft track;
an enhanced vision system comprised of at least one steerable, forward-looking device comprised of a sensor configured to capture non-visible radiation; and
an avionics system processor including at least one processor coupled to a non-transitory processor-readable medium storing processor-executable code and configured to:
receive the motion tracking data when the aircraft is on the ground,
receive the navigation data when the aircraft is in flight,
generate steering data as a function of the motion tracking data or the navigation data, where
the steering data is representative of a steering command commensurate to the first angular measurement when the aircraft is on the ground and the second angular measurement when the aircraft is in flight, and

provide the steering data to the at least one steerable, forward-looking device, whereby
the at least one steerable, forward-looking device is steered in response to and in compliance with the steering command, thereby
placing the sensor of the at least one forward-looking device into a position corresponding to the first angular measurement or the second angular measurement to capture the non-visible radiation of a ground scene or an in-flight scene, respectively.

2. The system of claim 1 , wherein the avionics system processor is a processor of at least one aircraft system.

3. The system of claim 2 , wherein the at least one aircraft system is comprised of at least one of the source of motion tracking data, the source of navigation data, and the enhanced vision system.

4. The system of claim 1 , wherein the second angular measurement between aircraft heading and aircraft track is a measurement of wind correction angle.

5. The system of claim 1 , wherein an image of the ground scene or the in-flight scene represented in the non-visible radiation is presented to the pilot via the enhanced vision system.

6. A device for generating a sensor steering command for at least one forward-looking image capture device, comprising:
an avionics system processor including at least one processor coupled to a non-transitory processor-readable medium storing processor-executable code and configured to:
receive motion tracking data from a source of motion tracking data representative of information corresponding to a first angular measurement of head position of a pilot inside an aircraft when the aircraft is on the ground;
receive navigation data from a source of navigation data representative of information corresponding to a second angular measurement between aircraft heading and aircraft track when the aircraft is in flight;
generate steering data as a function of the motion tracking data or the navigation data, where
the steering data is representative of a steering command commensurate to the first angular measurement when the aircraft is on the ground and the second angular measurement when the aircraft is in flight; and

provide the steering data to at least one steerable, forward-looking device of an enhanced vision system and comprised of a sensor configured to capture non-visible radiation, whereby
the at least one steerable, forward-looking device is steered in response to and in compliance with the steering command, thereby
placing the sensor of the at least one forward-looking device into a position corresponding to the first angular measurement or the second angular measurement to capture the non-visible radiation of a ground scene or an in-flight scene, respectively.

7. The device of claim 6 , wherein the avionics system processor is a processor of at least one aircraft system.

8. The device of claim 7 , wherein the at least one aircraft system is comprised of at least one of the source of motion tracking data, the source of navigation data, and the enhanced vision system.

9. The device of claim 6 , wherein the second angular measurement between aircraft heading and aircraft track is a measurement of wind correction angle.

10. The device of claim 6 wherein an image of the ground scene or the in-flight scene represented in the non-visible radiation is presented to the pilot via the enhanced vision system.

11. A method for generating a sensor steering command for at least one forward-looking image capture device, comprising:
receiving, by an avionics system processor including at least one processor coupled to a non-transitory processor-readable medium storing processor-executable code, motion tracking data from a source of motion tracking data representative of information corresponding to a first angular measurement of head position of a pilot inside an aircraft when the aircraft is on the ground;
navigation data from a source of navigation data representative of corresponding to a second angular measurement between aircraft heading and aircraft track when the aircraft is in flight;
generating steering data as a function of the motion tracking data or the navigation data, where
the steering data is representative of a steering command commensurate to the first angular measurement when the aircraft is on the ground and the second angular measurement when the aircraft is in flight; and

providing the steering data to at least one steerable, forward-looking device of an enhanced vision system and comprised of a sensor configured to capture non-visible radiation, whereby
the at least one steerable, forward-looking device is steered in response to and in compliance with the steering command, thereby
placing the sensor of the at least one forward-looking device into a position corresponding to the first angular measurement or the second angular measurement to capture the non-visible radiation of a ground scene or an in-flight scene, respectively.

12. The method of claim 11 , wherein the avionics system processor is a processor of at least one aircraft system.

13. The method of claim 12 , wherein the at least one aircraft system is comprised of at least one of the source of motion tracking data, the source of navigation data, and the enhanced vision system.

14. The method of claim 11 , wherein the second angular measurement between aircraft heading and aircraft track is a measurement of wind correction angle.

15. The method of claim 11 , wherein an image of the ground scene or the in-flight scene represented in the non-visible radiation is presented to the pilot via the enhanced vision system.
