Abstract

A method for controlling an unmanned aerial vehicle includes assessing whether the UAV is within a flight-restriction region and, based on the assessment, generating signals that cause the UAV to take a flight response measure when within the flight-restriction region. The flight-restriction region is generated based on a location of a reference restriction feature and a functional parameter of the reference restriction feature.

First claim

What is claimed is:

1 . A method for controlling an unmanned aerial vehicle (UAV), comprising:
assessing, with aid of one or more processors, whether the UAV is within a flight-restriction region, the flight-restriction region being generated based on a location of a reference restriction feature and a functional parameter of the reference restriction feature; and generating, based on the assessment, signals that cause the UAV to take a flight response measure when within the flight-restriction region.

2 . The method of claim 1 , wherein the reference restriction feature includes an airport.

3 . The method of claim 1 , wherein the location of the reference restriction feature is determined based on a reference point.

4 . The method of claim 3 , wherein the reference point is a center of an airport, a center of a runway, or a location of a control tower.

5 . The method of claim 1 , wherein the functional parameter indicates a flight characteristic of a flying object that interacts with the reference restriction feature.

6 . The method of claim 5 , wherein the flight characteristic of the flying object includes a type of the flying object.

7 . The method of claim 5 , wherein the flight characteristic of the flying object includes a take-off path or a landing path of the flying object or an altitude limitation of the flying object.

8 . The method of claim 1 , wherein the functional parameter includes a reference restriction feature characteristic of the reference restriction feature.

9 . The method of claim 8 , wherein the reference restriction feature characteristic includes a physical characteristic of an airport.

10 . The method of claim 9 , wherein the physical characteristic of the airport includes a location, an orientation, a length, a width, or an extended length of a runway.

11 . The method of claim 9 , wherein the physical characteristic of the airport includes a size or a shape of a helipad.

12 . The method of claim 1 , wherein the flight-restriction region is generated based on a shape of the flight-restriction region.

13 . The method of claim 1 , wherein the flight-restriction region is generated based on a size of the flight-restriction region.

14 . The method of claim 1 , wherein the flight response measure includes at least one of landing the UAV, staying outside of the flight-restriction region or immediately exiting the flight-restriction region, or providing a demand to an operator of the UAV.

15 . The method of claim 1 , further comprising:
assessing, with aid of the one or more processors, whether the UAV is within a warning region based on the location of the reference restriction feature or a flight characteristic of a flying object.

16 . The method of claim 15 , wherein the warning region encompasses the flight-restriction region.

17 . The method of claim 1 , wherein the flight restriction region is generated further based on UAV information.

18 . The method of claim 17 , wherein the UAV information includes a safety gap between the UAV and one or more aerial vehicles.

19 . A system for effecting flight response measures of an unmanned aerial vehicle (UAV) comprising:
a flight controller configured to generate signals for a flight of the UAV, wherein the signals are generated based on assessment of whether the UAV is within a flight-restriction region, the flight-restriction region being generated based on a location of a reference restriction feature and a functional parameter of the reference restriction feature, wherein the signals cause the UAV to take a flight response measure when within the flight-restriction region.

20 . The system of claim 19 , wherein the reference restriction feature includes an airport.
