A control device for an unmanned aerial vehicle (UAV) and a control method therefor are provided. The control device includes a sensing device, an image receiver, a control transmitter, a display, and a processor. The sensing device is used to sense an action of the user. The image receiver is used to receive an image including at least a part or all of the body in the UAV from a first image capturing device of the UAV. The processor uses the display to continuously present the image. The processor obtains the action by the sensing device, converts the action into the control signal corresponding to the UAV, and transmits the control signal to the UAV through the control transmitter. The UAV is controlled by the control signal transmitted by the control device.
