Abstract

An aerial system and method of operating an aerial system is provided. The aerial system includes a body, a lift mechanism, a processing system, a camera, and a sensor module. The lift mechanism is coupled to the body and configured to controllably provide lift and/or thrust. The processing system is configured to control the lift mechanism to provide flight to the aerial system. The camera is coupled to the body and is configured to obtain images of an environment proximate the aerial system. The sensor module is coupled to the body and includes an emitter and a receiver. The receiver is configured to sense data related to an ambient environment associated with the aerial system. The processing system controls a controllable parameter of the lift mechanism or the emitter as a function of the sensed data.

a body;
a lift mechanism coupled to the body and configured to controllably provide lift and/or thrust;
a processing system configured to control the lift mechanism to provide flight to the aerial system;
a camera coupled to the body and configured to obtain images of an environment proximate the aerial system; and,
a sensor module coupled to the body and including first and second sets of emitters and a receiver, each set of emitters including at least one emitter, the receiver being configured to sense data related to an ambient environment associated with the aerial system, the processing system being further configured to control a controllable parameter of the lift mechanism or one of the emitters as a function of the sensed data, the processing system being further configured to switch between the first and second sets of emitters as a function of the sensed data, the first set of emitters being associated with normal light conditions and the second set of emitters being associated with high-noise and/or low-light conditions.

2. The aerial system, as set forth in claim 1 , wherein the processing system is configured to detect a high-noise and/or a low-light ambient condition as a function of the sensed date and to actuate the second set of emitters in response to detecting the high-noise and/or low-light ambient condition.

3. The aerial system, as set forth in claim 2 , wherein the first and second sets of emitters are configured to provide a visual reference to a user.

4. The aerial system, as set forth in claim 2 , wherein the first and second sets of emitters are configured to illuminate a target object and/or a region associated with the camera.

5. The aerial system, as set forth in claim 2 , wherein an amount of actuation of one of the emitters is a function of ambient light detected by the receiver.

6. The aerial system, as set forth in claim 1 , wherein the processing system is configured to control the emitters as a function of an operation context of the aerial system.

7. The aerial system, as set forth in claim 6 , wherein the operation context is an operation mode of the aerial system.

8. The aerial system, as set forth in claim 1 , further comprising at least one aerial system sensor for detecting one or more parameters of aerial system operation, the processing system being further configured to adjust emitter operation as a function of sensed data from the receiver and/or the at least one aerial system sensor.

9. The aerial system, as set forth in claim 1 , wherein the processing system is configured to send the sensed date to an off-board system for analysis.

13. The aerial system, as set forth in claim 12 , wherein the flight instructions override any remote control instructions.

14. The aerial system, as set forth in claim 12 , wherein the processing system is configured to identify any objects in a current flight path as a function of the sensed data and generate the flight instructions to avoid any identified objects.

15. The aerial system, as set forth in claim 1 , wherein the camera is downward facing and configured to capture images an automated landing procedure, the processing system being configured to determine a distance between aerial system and a landing surface as a function of the sensed data to control the emitter as a function of the distance and to generate landing instructions based on the distance and images(s) capture by the camera, the processing system further configured to control the lift mechanism as a function of the landing instructions.

16. An aerial system, comprising:
a body;
a lift mechanism coupled to the body and configured to controllably provide lift and/or thrust;
