Abstract

The present disclosure relates to a remotely operated underwater vehicle and a control method therefor. The remotely operated underwater vehicle comprises a body having an imaging unit and a control unit; a power unit disposed on the body; a beacon unit for being worn on a part of a user's body, wherein the beacon unit can emit a plurality of optical control signals with different brightness; and the control unit can control the power unit to respond according to the optical control signals collected by the imaging unit to adjust an action and a posture of the body.

Claims (33)

1. A remotely operated underwater vehicle, comprising:

a body having an imaging unit and a control unit;

a power unit disposed on the body; and

a beacon unit for being worn on a part of a user's body,

wherein the beacon unit can emit a plurality of optical control signals with different brightness, and

the control unit can control the power unit to respond according to the optical control signals collected by the imaging unit to adjust an action and a posture of the body, wherein

a shape formed by a plurality of specific movement trajectories of the beacon unit is preset in the control unit, and a correlation between the shape and a corresponding movement of the body is established; and

when the movement trajectory of the beacon unit collected by the imaging unit conforms to the preset shape, the control unit controls the body to complete the corresponding movement.

2. The remotely operated underwater vehicle of claim 1 , wherein

the beacon unit can transmit a plurality of optical control signals in a flashing manner at different frequencies.

3. The remotely operated underwater vehicle of claim 1 , wherein

a plurality of power units are disposed at different locations on the body; and

the control unit can control the corresponding power unit to respond according to the optical control signals collected by the imaging unit to adjust an action and a posture of the body.

4. The remotely operated underwater vehicle of claim 1 , comprising

a sensor unit disposed on the body for sensing a diving depth and a hovering posture of the body.

5. A method for controlling a remotely operated underwater vehicle, comprising

emitting a plurality of optical control signals with different brightness from a beacon unit worn on a part of a user's body; and

controlling a power unit via a control unit disposed on a body of the remotely operated underwater vehicle to respond according to the optical control signals collected by an imaging unit to adjust an action and a posture of the body, wherein

a shape formed by a plurality of specific movement trajectories of the beacon unit is preset in the control unit, and a correlation between the shape and a corresponding movement of the body is established; and

when the movement trajectory of the beacon unit collected by the imaging unit conforms to the preset shape, the control unit controls the body to complete the corresponding movement.

6. The method for controlling a remotely operated underwater vehicle of claim 5 , wherein

the beacon unit can transmitting a plurality of optical control signals in a flashing manner at different frequencies.

7. The method for controlling a remotely operated underwater vehicle of claim 5 , wherein

when the beacon unit transmits an optical control signal of a tracking instruction, and the beacon unit is at a focus position of the imaging unit, the control unit controls the power unit to respond such that the body tracks the movement of the beacon unit; and

when the beacon unit transmits an optical control signal of a tracking instruction, but the beacon unit is not at a focus position of the imaging unit, the control unit firstly controls the power unit to respond such that the beacon unit is located at the focus position of the imaging unit, and then controls the power unit to respond such that the body tracks the movement of the beacon unit.

8. The method for controlling a remotely operated underwater vehicle of claim 5 , wherein

when the beacon unit transmits an optical control signal of a spot hovering, the control unit can control the power unit to respond according to the optical control signal collected by the imaging unit such that the body is spot hovered at the corresponding location; and

if the sensor unit senses that an obtained diving depth and a hovering posture of the body and the optical control signal of the spot hovering have an error, the control unit controls the power unit to make a corresponding compensation movement.

9. A method for controlling a remotely operated underwater vehicle, comprising

emitting a plurality of optical control signals with different brightness from a beacon unit worn on a part of a user's body; and

controlling a power unit via a control unit disposed on a body of the remotely operated underwater vehicle to respond according to the optical control signals collected by an imaging unit to adjust an action and a posture of the body, wherein

when the beacon unit transmits an optical control signal of a tracking instruction, and the beacon unit is at a focus position of the imaging unit, the control unit controls the power unit to respond such that the body tracks the movement of the beacon unit; and

when the beacon unit transmits an optical control signal of a tracking instruction, but the beacon unit is not at a focus position of the imaging unit, the control unit firstly controls the power unit to respond such that the beacon unit is located at the focus position of the imaging unit, and then controls the power unit to respond such that the body tracks the movement of the beacon unit.
