Abstract

Claims (44)

1 . A method for tracking a target comprising:

identifying the target from an image captured by an imaging device based on target information, the imaging device being carried by an aerial vehicle via a carrier;

detecting a deviation of the target from a predetermined characteristic; and

adjusting at least one of the aerial vehicle or the carrier to reduce the deviation, wherein adjusting the at least one of the aerial vehicle or the carrier comprises adjusting a configuration related to an angular velocity of the imaging device relative to at least an axis of the imaging device, to keep the target substantially at predetermined coordinates of at least one further image.

2 . The method of claim 1 , wherein the target information comprises at least one of color, texture, dimension, size, or location.

3 . The method of claim 1 , further comprising:

receiving the target information by receiving an entry of the target type-information or by receiving a selection of a pre-existing target pattern or type.

4 . The method of claim 1 , further comprising:

receiving a selection of one or more candidate targets from one or more previous images; and

extracting and generalizing features or characteristics of the one or more candidate targets to produce the target information.

5 . The method of claim 1 , wherein identifying the target comprises identifying the target based on the target information using an image recognition method.

6 . The method of claim 5 , wherein the image recognition method comprises at least one of an approach based on CAD-like object models, an appearance-based method, a feature-based method, or a genetic algorithm.

7 . The method of claim 1 , wherein:

the deviation is related to a change in position of the target; and

adjusting the at least one of the aerial vehicle or the carrier comprises adjusting at least a first configuration related to a first angular velocity of the imaging device at least-relative to a pitch axis of the imaging device.

8 . The method of claim 1 , further comprising:

maintaining, within a predetermined degree of tolerance, an expected position, and/or an expected size of the target in one or more subsequent images captured by the imaging device.

9 . The method of claim 1 , further comprising:

transmitting, in substantially real-time, images captured by the imaging device to a remote controller.

10 . A system for controlling an aerial vehicle comprising:

an imaging device coupled to the aerial vehicle via a carrier configured to permit the image device to move relative to the aerial vehicle; and

one or more processors configured to:

identify a target from an image captured by the imaging device based on target information, the target information comprising information manually entered by a user;

detect a deviation of the target from a predetermined characteristic; and

adjust at least one of the aerial vehicle or the carrier to reduce the deviation, wherein adjusting the at least one of the aerial vehicle or the carrier comprises adjusting a configuration related to an angular velocity of the imaging device relative to at least an axis of the imaging device, to keep the target substantially at predetermined coordinates of at least one further image.

11 . The system of claim 10 , wherein the target information comprises at least one of color, texture, dimension, size, or location.

12 . The system of claim 10 , further comprising:

one or more receivers configured to receive the target information from a remote controller, the target information being entered by a user on the remote controller or being a pre-existing target pattern or type selected by the user on the remote controller.

13 . The system of claim 10 , wherein the target information is produced by extracting and generalizing features or characteristics of one or more candidate targets selected from one or more previous images.

14 . The system of claim 10 , wherein the one or more processors are further configured to identify the target based on the target information using an image recognition method.

15 . The system of claim 14 , wherein the image recognition method comprises at least one of an approach based on CAD-like object models, an appearance-based method, a feature-based method, or a genetic algorithm.

16 . The system of claim 10 , wherein:

the deviation is related to a change in position of the target; and

the one or more processors are further configured to adjust a first configuration related to at least a first angular velocity of the imaging device relative to a pitch axis of the imaging device.

17 . The system of claim 10 , wherein the one or more processors are further configured to maintain, within a predetermined degree of tolerance, an expected position, and/or an expected size of the target in one or more subsequent images captured by the imaging device.

18 . The system of claim 10 , wherein the one or more processors are further configured to transmit, in substantially real-time, images captured by the imaging device to the remote controller.

19 . An aerial vehicle comprising:

one or more receivers configured to receive from a remote controller target information of a target to be tracked by an imaging device coupled to the aerial vehicle via a carrier; and

one or more processors configured to:

receive, wirelessly from the target, location information of the target;

identify the target from an image captured by the imaging device based on target information, the target information comprising the location information of the target, the imaging device being carried by an aerial vehicle via a carrier;

detect a deviation of the target from a predetermined characteristic; and

adjust at least one of the aerial vehicle or the carrier to reduce the deviation, wherein adjusting the at least one of the aerial vehicle or the carrier comprises adjusting a configuration related to an angular velocity of the imaging device relative to at least an axis of the imaging device, to keep the target substantially at predetermined coordinates of at least one further image.

20 . The aerial vehicle of claim 19 , wherein the target information comprises at least one of color, texture, dimension, size, or location, and is received by receiving an entry of the target information or by receiving a selection of a pre-existing target pattern or type.
