Abstract

An unmanned aerial vehicle (UAV) control method is based on a headless mode and applied to a remote controller and a related aircraft assembly. The UAV control method includes receiving a first orientation datum generated by a drone, acquiring a second orientation datum relevant to the remote controller and provided by an electronic compass, acquiring an operation angle datum generated by a joystick of the remote controller, and computing a difference between the first orientation datum and a sum of the second orientation datum and the operation angle datum for setting as fly angle information of the drone.

First claim

What is claimed is:

1 . An unmanned aerial vehicle control method with a headless mode, the unmanned aerial vehicle control method comprising:
receiving a first orientation datum generated by a drone; acquiring a second orientation datum relevant to a remote controller and provided by an electronic compass; acquiring an operation angle datum generated by a joystick of the remote controller; and computing a difference between the first orientation datum and a sum of the second orientation datum and the operation angle datum for setting as fly angle information of the drone.

2 . The unmanned aerial vehicle control method of claim 1 , wherein the unmanned aerial vehicle control method is applied to the remote controller having the electronic compass, and adapted to control a movement of the drone in the same direction as the operation angle datum.

3 . The unmanned aerial vehicle control method of claim 1 , further comprising:
utilizing a wireless transmission module of the remote controller to transmit the fly angle information to the drone.

4 . The unmanned aerial vehicle control method of claim 1 , wherein the first orientation datum is an absolute coordinate orientation of the drone, and the second orientation datum is an absolute coordinate orientation of the remote controller.

5 . The unmanned aerial vehicle control method of claim 1 , wherein the unmanned aerial vehicle control method determines a nose azimuth of the drone by the first orientation datum, and computes a difference between the first orientation datum and the second orientation datum, so as to calibrate the operation angle datum via the difference for acquiring the fly angle information.

6 . A remote controller of controlling a movement of a drone, the remote controller comprising:
a wireless transmission module adapted to receive a first orientation datum generated by a drone; an electronic compass adapted to provide a second orientation datum of the remote controller; a joystick adapted to generate an operation angle datum according to a user's gesture; and an operation processor electrically connected to the wireless transmission module, the electronic compass and the joystick, the operation processor being adapted to compute a difference between the first orientation datum and a sum of the second orientation datum and the operation angle datum for setting as fly angle information of the drone, so as to control the movement of the drone in the same direction as the operation angle datum.

7 . The remote controller of claim 6 , wherein the operation processor utilizes the wireless transmission module to transmit the fly angle information to the drone.

8 . The remote controller of claim 6 , wherein the first orientation datum is an absolute coordinate orientation of the drone, and the second orientation datum is an absolute coordinate orientation of the remote controller.

9 . The remote controller of claim 6 , wherein the operation processor determines a nose azimuth of the drone by the first orientation datum, and computes a difference between the first orientation datum and the second orientation datum, so as to calibrate the operation angle datum via the difference for acquiring the fly angle information.

10 . An aircraft assembly comprising:
a drone adapted to provide and transmit a first orientation datum; and a remote controller of controlling a movement of the drone, the remote controller comprising:
a wireless transmission module adapted to receive the first orientation datum;
an electronic compass adapted to provide a second orientation datum of the remote controller;
a joystick adapted to generate an operation angle datum according to a user's gesture; and
an operation processor electrically connected to the wireless transmission module, the electronic compass and the joystick, the operation processor being adapted to compute a difference between the first orientation datum and a sum of the second orientation datum and the operation angle datum for setting as fly angle information of the drone, so as to control the movement of the drone in the same direction as the operation angle datum.

11 . The aircraft assembly of claim 10 , wherein the operation processor utilizes the wireless transmission module to transmit the fly angle information to the drone.

12 . The aircraft assembly of claim 10 , wherein the first orientation datum is an absolute coordinate orientation of the drone, and the second orientation datum is an absolute coordinate orientation of the remote controller.

13 . The aircraft assembly of claim 10 , wherein the operation processor determines a nose azimuth of the drone by the first orientation datum, and computes a difference between the first orientation datum and the second orientation datum, so as to calibrate the operation angle datum via the difference for acquiring the fly angle information.
