Abstract

A system of determining a flight path for an aerial vehicle, includes a memory storing a program code, and a processor configured to execute the program code to identify, during a flight, an abnormal state occurring at a first location, in response to the abnormal state, control the aerial vehicle to fly along a first flight path from the first location to a first destination, after the aerial vehicle arrives at the first destination, evaluate a status of the aerial vehicle at the first destination to obtain an evaluation result, and based on the evaluation result, determine a second flight path of the aerial vehicle to a second destination. The first flight path is a reverse of a last flight path of the aerial vehicle before the aerial vehicle reaches the first location.

First claim

What is claimed is:

1. A system of determining a flight path for an aerial vehicle, comprising:
a memory storing a program code; and
a processor configured to execute the program code to:
identify, during a flight, an abnormal state occurring at a first location;
in response to the abnormal state, control the aerial vehicle to fly along a first flight path from the first location to a first destination, the first flight path being a reverse of a last flight path of the aerial vehicle before the aerial vehicle reaches the first location;
after the aerial vehicle arrives at the first destination, evaluate a status of the aerial vehicle at the first destination to obtain an evaluation result; and
based on the evaluation result, determine a second flight path of the aerial vehicle to a second destination.

2. The system of claim 1 , wherein the processor is further configured to execute the program code to:
control the aerial vehicle to fly to and land at the second destination.

3. The system of claim 1 , wherein the abnormal state includes a change in a state of signal transmission between the aerial vehicle and a control device.

4. The system of claim 3 , wherein the change in the state of signal transmission includes a loss or weakening of a signal during the signal transmission between the aerial vehicle and the control device.

5. The system of claim 3 , wherein the change in the state of signal transmission includes a change of a transmission rate between the aerial vehicle and the control device.

6. The system of claim 1 , wherein the first destination is selected based on user input or selected by the aerial vehicle.

7. The system of claim 1 , wherein the status of the aerial vehicle includes a normal state or the abnormal state.

8. The system of claim 1 , wherein the first destination is selected by the aerial vehicle with aid of one of more sensors.

9. The system of claim 1 , wherein the first destination is selected based on flight environment of the aerial vehicle.

10. The system of claim 1 , wherein the aerial vehicle is one of one or more aerial vehicles, and the first destination includes a location detected by one or more sensors on the one or more aerial vehicles during a previous flight.

11. The system of claim 1 , wherein the first destination includes a last point at which signal transmission between the aerial vehicle and a control device is successful.

12. The system of claim 1 , wherein the first destination is within a predetermined distance from the first location.

13. The system of claim 1 , wherein the second destination is selected based on user input from a control device.

14. The system of claim 1 , wherein the second destination is a starting point of the flight.

15. The system of claim 1 , wherein the processor is further configured to execute the program code to:
select the second destination including in response to no user input being received within a first predetermined period, controlling the aerial vehicle to hover for a second predetermined period.

16. The system of claim 1 , wherein the second destination is a predetermined destination of the flight before the abnormal state occurring at the first location is identified.

17. The system of claim 1 , wherein the second destination includes a service point providing one or more services to the aerial vehicle to restore normal operation, and the second flight path is determined based on a flight distance to the service point.

18. The system of claim 1 , wherein the second flight path is further determined based on user input from a control device.

19. The system of claim 1 , wherein the first destination includes a safe point.

20. A method of determining a flight path for an aerial vehicle, comprising:
identifying, during a flight and with aid of one or more processors, an abnormal state occurring at a first location;
in response to the abnormal state, controlling the aerial vehicle to fly along a first flight path from the first location to a first destination, the first flight path being a reverse of a last flight path of the aerial vehicle before the aerial vehicle reaches the first location;
after the aerial vehicle arrives at the first destination, evaluating a status of the aerial vehicle at the first destination to obtain an evaluation result; and
based on the evaluation result, determining a second flight path of the aerial vehicle to a second destination.
