Flight control for flight-restricted regions
A movable object includes one or more processors individually or collectively configured to assess a location of the movable object, calculate a distance between the movable object and a restricted region using the location of the movable object, assess whether the distance falls within a first distance threshold, and instruct the movable object to take a movement response measure selected from (1) a first movement response measure when the distance falls within the first distance threshold, and (2) a second movement response measure different from the first movement response measure when the distance falls outside the first distance threshold. The first movement response measure is related to a current movement status of the movable object.
1. A movable object, comprising:
one or more processors individually or collectively configured to:
obtain a location of the movable object;
in response to the movable object being at a first flight-restricted proximity zone, instruct the movable object to take a first movement response measure, the first movement response measure being related to a current movement status of the movable object, and a distance between the first flight-restricted proximity zone and a restricted region being within a first distance threshold; and
in response to the movable object being at a second flight-restricted proximity zone, instruct the movable object to take a second movement response measure, the second movement response measure including providing an operator of the movable object with a time period to move the movable object, and the time period being a grace period after which the movable object is controlled without taking input from the operator of the movable object into account, and a distance between the second flight-restricted proximity zone and the restricted region being outside the first distance threshold.
2. The movable object of claim 1 , wherein the restricted region is selected from a plurality of possible restricted regions based on proximity of the movable object to each of the plurality of possible restricted regions.
3. The movable object of claim 2 , wherein one or more restricted regions outside a second distance threshold from the movable object are excluded from the plurality of possible restricted regions.
4. The movable object of claim 1 , wherein the first movement response measure further comprises at least one of:
preventing the movable object from taking off when the status of the movable object is staying on a surface, or
causing the movable object to descend or hover over a location when the moveable object is moving, wherein a rate at which the movable object descends is determined based on the location of the movable object.
5. The movable object of claim 1 , wherein the second movement response measure further comprises providing an alert or a warning to the operator of the movable object.
6. The movable object of claim 1 , wherein the one or more processors are further configured to limit the movable object's movement within a predetermined movement limitation region.
7. The movable object of claim 6 , wherein the movement limitation region is defined by a user using a graphical user interface or a user interface.
8. The movable object of claim 1 , wherein the first movement response measure includes taking control of the movable object away from the operator of the movable object.
9. The movable object of claim 1 , wherein the first flight response measure permits less control by the operator for the movable object than the second flight response measure.
10. A method for controlling a movable object, comprising:
obtaining a location of the movable object;
in response to the movable object being at a first flight-restricted proximity zone, instructing the movable object to take a first movement response measure, the first movement response measure being related to a current movement status of the movable object, and a distance between the first flight-restricted proximity zone and a restricted region being within a first distance threshold; and
in response to the movable object being at a second flight-restricted proximity zone, instructing the movable object to take a second movement response measure, the second movement response measure including providing an operator of the movable object with a time period to move the movable object, and the time period being a grace period after which the movable object is controlled without taking input from the operator of the movable object into account, and a distance between the second flight-restricted proximity zone and the restricted region being outside the first distance threshold.
11. The method of claim 10 , wherein the restricted region is selected from a plurality of possible restricted regions based on proximity of the movable object to each of the plurality of possible restricted regions.
12. The method of claim 11 , wherein one or more restricted regions outside a second distance threshold from the movable object are excluded from the plurality of possible restricted regions.
13. The method of claim 10 , wherein the first movement response measure further comprises at least one of:
preventing the movable object from taking off when the current movement status of the movable object is staying on a surface, or
causing the movable object to descend or hover over a location when the moveable object is moving, wherein a rate at which the movable object descends is determined based on the location of the movable object.
14. The method of claim 10 , wherein the second movement response measure further comprises providing an alert or a warning to the operator of the movable object.
15. The method of claim 10 , further comprising limiting the movable object's movement within a predetermined movement limitation region.
16. The method of claim 15 , wherein the movement limitation region is defined by a user using a graphical user interface or a user interface.
17. One or more non-transitory computer-readable storage media storing computer-executable instructions that, when executed by a computing system, configure the computing system to perform the method of claim 10 .
18. The computer-readable storage media of claim 17 , wherein the restricted region is selected from a plurality of possible restricted regions based on proximity of the movable object to each of the plurality of possible restricted regions.
19. The computer-readable storage media of claim 18 , wherein restricted regions outside a second distance threshold from the movable object are excluded from the plurality of possible restricted regions.
20. The computer-readable storage media of claim 17 , wherein the first movement response measure further comprises at least one of:
preventing the movable object from taking off when the current movement status of the movable object is staying on a surface, or
causing the movable object to descend or hover over a location when the moveable object is moving, wherein a rate at which the movable object descends is determined based on the location of the movable object.
