Abstract

The disclosed embodiments describe collision warning devices, controllers, and computer readable media. A collision warning device for towing vehicles includes a housing, a scanning sensor, a display, and a controller. The housing is configured to be secured to at least one of a tow operator and a tug during aircraft towing operations. The a scanning sensor is secured to the housing and is configured to scan an aircraft and to scan an object in an environment surrounding the aircraft. The controller is mounted to the housing and is operably coupled with the scanning sensor and the display. The controller is configured to generate a three dimensional (3D) model of the aircraft and the environment based on a signal output from the scanning sensor, and to calculate potential collisions between the aircraft and the object based on the 3D model.

Claims

1. A collision warning device comprising:

a housing configured to be secured to at least one of a tow operator and a tug during aircraft towing operations;

a scanning sensor secured to the housing and configured to scan an aircraft and to scan an environment surrounding the aircraft;

a display configured to present visual data for the tow operator; and

a controller mounted to the housing and operably coupled with the scanning sensor and the display, the controller configured to;

generate a three dimensional (3D) model of the aircraft and the environment based on a signal output from the scanning sensor; and

calculate a potential collision between the aircraft and an object in the environment based on the 3D model.

2. The collision warning device of claim 1, wherein the controller is further configured to present a warning on the display in response to calculating the potential collision.

3. The collision warning device of claim 1, wherein the housing is configured to be worn on a head of the tow operator during the aircraft towing operations.

4. The collision warning device of claim 3, wherein the display is an augmented reality display, and wherein the controller is further configured to overlay a warning on the augmented reality display in response to calculating the potential collision between the aircraft and the object.

5. The collision warning device of claim 4, wherein the controller is further configured to alert the tow operator by overlaying on the augmented reality display a distance between the aircraft and the object.

6. The collision warning device of claim 1, wherein the controller is further configured to calculate distances between the aircraft and the object based at least in part on sensor signals from the scanning sensor and to alert the tow operator of the potential collision in response to a calculated distance dropping below a threshold.

7. The collision warning device of claim 1, wherein the controller is further configured to calculate a path of the aircraft in response to detecting towing operations.

8. The collision warning device of claim 7, further comprising movement sensors configured to output movement signals indicating movement of the collision warning device, wherein the controller is configured to calculate the path of the aircraft based, at least in part, on the movement signals.

9. The collision warning device of claim 8, wherein the controller is further configured to calculate a suggested path that will avoid the potential collision between the aircraft and the object, and wherein the controller is further configured to cause the display to present the suggested path for the tow operator.

10. A controller comprising:

a processor; and

a memory unit storing instructions that, when executed by the processor, cause the controller to;

generate a three dimensional (3D) model of an aircraft and an environment around the aircraft based on a signal output from a scanning sensor; and

calculate potential collisions between the aircraft and an object in the environment based on the 3D model.

11. The controller of claim 10, wherein the instructions further cause the controller to generate signals that cause a display to present a warning in response to calculating the potential collision.

12. The controller of claim 10, wherein the instructions further cause the controller to overlay a warning on an augmented reality display in response to calculating the potential collision between the aircraft and the object.

13. The controller of claim 12, wherein the instructions further cause the controller to alert a tow operator by overlaying on the augmented reality display a distance between the aircraft and the object.

14. The controller of claim 10, wherein the instructions further cause the controller to calculate distances between the aircraft and the object based at least in part on sensor signals from the scanning sensor and to alert a tow operator of a potential collision in response to a calculated distance dropping below a threshold.

15. The controller of claim 10, wherein the instructions further cause the controller to calculate a suggested path that will avoid the potential collision between the aircraft and the object, and to generate a signal that causes a display to present the suggested path for a tow operator.

16. A non-transitory computer readable medium comprising instructions that cause a controller to:

generate a three dimensional (3D) model of an aircraft and an environment around the aircraft based on a signal output from a scanning sensor; and

calculate a potential collision between the aircraft and an object in the environment based on the 3D model.

17. The non-transitory computer readable medium of claim 16, wherein the instructions further cause the controller to generate signals that cause a display to present a warning in response to calculating the potential collision.

18. The non-transitory computer readable medium of claim 16, wherein the instructions further cause the controller to overlay a warning on an augmented reality display in response to calculating the potential collision between the aircraft and the object.

19. The non-transitory computer readable medium of claim 16, wherein the instructions further cause the controller to alert a tow operator by overlaying on an augmented reality display a distance between the aircraft and the object.

20. The non-transitory computer readable medium of claim 16, wherein the instructions further cause the controller to calculate a suggested path that will avoid the potential collision between the aircraft and the object, and to generate a signal that causes a display to present the suggested path for a tow operator.
