Abstract

A method for adaptive mission execution by an unmanned aerial vehicle includes receiving a set of pre-calculated mission parameters corresponding to an initial UAV mission; collecting UAV operation data during flight of the unmanned aerial vehicle; calculating a set of modified mission parameters from the set of pre-calculated mission parameters and the UAV operation data, the set of modified mission parameters corresponding to a modified UAV mission; and executing the modified UAV mission on the unmanned aerial vehicle.

Claims

1. A method for adaptive mission execution by an unmanned aerial vehicle comprising:

receiving a set of pre-calculated mission parameters corresponding to an initial UAV mission, the pre-calculated mission parameters defining a first area to be imaged by a camera of the unmanned aerial vehicle at a first imaging resolution and a first set of camera parameters;

initiating execution of the initial UAV mission;

collecting UAV operation data during flight of the unmanned aerial vehicle, the UAV operation data comprising aerial images taken at the first imaging resolution;

wherein collecting UAV operation data further comprises performing an analysis of the aerial images;

calculating a set of modified mission parameters from the set of pre-calculated mission parameters and the analysis of aerial images, the set of modified mission parameters corresponding to a modified UAV mission; and

executing the modified UAV mission on the unmanned aerial vehicle.

2. The method of claim 1, wherein calculating the set of modified mission parameters comprises modifying the first set of camera parameters based on the analysis of aerial images.

3. The method of claim 1, wherein performing an analysis of the aerial images comprises identifying a first image of the aerial images as unsatisfactory;

wherein calculating a set of modified mission parameters comprises modifying the set of pre-calculated mission parameters to allow a scene captured by the first image to be recaptured in another image.

4. The method of claim 1, wherein performing an analysis of the aerial images comprises determining that the first imaging resolution is too low for satisfactory image capture;

wherein calculating a set of modified mission parameters comprises modifying the set of pre-calculated mission parameters to allow images to be captured at a second imaging resolution;

wherein the second imaging resolution is higher than the first imaging resolution.

5. The method of claim 4, further comprising prompting a user, via a management application, to set the second imaging resolution.

6. A method for adaptive mission execution by an unmanned aerial vehicle comprising:

receiving a set of pre-calculated mission parameters corresponding to an initial UAV mission;

collecting UAV operation data during flight of the unmanned aerial vehicle;

calculating a set of modified mission parameters from the set of pre-calculated mission parameters and the UAV operation data, the set of modified mission parameters corresponding to a modified UAV mission; and

executing the modified UAV mission on the unmanned aerial vehicle.

7. The method of claim 6, further comprising executing a pre-mission flight test;

wherein collecting UAV operation data during flight of the unmanned aerial vehicle comprises collecting UAV operation data during the pre-mission flight test.

8. The method of claim 7, wherein executing a pre-mission flight test comprises measuring battery voltage or battery current for a plurality of motor power settings during flight along a test flightpath.

9. The method of claim 8, wherein executing a pre-mission flight tests comprises capturing aerial images and analyzing captured images to determine operational status of a camera coupled to the UAV.

10. The method of claim 7, further comprising initiating execution of the initial UAV mission;

wherein collecting UAV operation data during flight of the unmanned aerial vehicle comprises collecting UAV operation data during the pre-mission flight test and during execution of the initial UAV mission;

wherein executing the modified UAV mission comprises executing the modified UAV mission after initiating and before completing execution of the initial UAV mission.

11. The method of claim 6, further comprising initiating execution of the initial UAV mission;

wherein collecting UAV operation data during flight of the unmanned aerial vehicle comprises collecting UAV operation data during execution of the initial UAV mission;

wherein executing the modified UAV mission comprises executing the modified UAV mission after initiating execution of the initial UAV mission.

12. The method of claim 11, wherein the set of pre-calculated mission parameters comprise a first flightpath and a first set of UAV speeds corresponding to the first flightpath;

wherein the set of modified mission parameters comprise a second flightpath and a second set of UAV speeds corresponding to the second flightpath;

wherein the second flightpath is modified from the first flightpath.

13. The method of claim 12, wherein the second set of UAV speeds is modified from the first set of UAV speeds.

14. The method of claim 13, wherein collecting UAV operation data during flight of the unmanned aerial vehicle comprises collecting UAV battery charge data;

wherein calculating the set of modified mission parameters comprises modifying the set of pre-calculated mission parameters based on the UAV battery charge data.

15. The method of claim 14, wherein collecting UAV operation data further comprises processing the UAV battery charge data to indicate that the unmanned aerial vehicle is incapable of completing the initial UAV mission;

wherein calculating the set of modified mission parameters comprises verifying that the unmanned aerial vehicle is capable of completing the modified UAV mission.
