Background technique

An unmanned aerial vehicle is an unmanned aerial vehicle that is operated by a radio remote control device or its own program control device. Unmanned aerial vehicles are divided into large unmanned aerial vehicles and small unmanned aerial vehicles. According to their functions, they can be divided into military and civilian. When the existing unmanned aerial vehicle is tracking and shooting the target, the flying hand manually controls the unmanned aerial vehicle, which is not only inefficient, the captured image is blurred and not coherent, and the manual operation is easy to cause a safety hazard. Further, the propeller of the existing unmanned aerial vehicle generates a large noise during the flight, and the noise generated by the propeller itself may affect the shooting effect.

To achieve the above object, the invention provides an unmanned aerial vehicle comprising an unmanned aerial vehicle main body, a plurality of rotors, a telescopic rod and a photographing device, wherein the unmanned aerial vehicle main body is connected to the rotor and the telescopic rod, The telescopic rod is disposed under the UAV main body, and the photographing device is disposed at an end of the telescopic rod, wherein: the rotor provides flight power to the UAV to make the UAV Flying in the air; the UAV host controls the telescopic rod to extend a preset distance to move the photographing device away from the rotor preset distance; the UAV host is configured to control the photographing according to an initial target image The device tracks the live image of the target in the air.

Compared with the prior art, the invention can track the target in real time, and shoot the target in real time, improve the shooting efficiency of the unmanned aerial vehicle, avoid the manual control of the unmanned aerial vehicle tracking target by the flying hand, and reduce the flying hand control. The difficulty of the aircraft improves the safety factor of the unmanned aerial vehicle. In addition, the photographing device is away from the propeller preset distance to avoid the propeller rotation of the unmanned aerial vehicle The noise generated during the transition affects the shooting effect.

BRIEF DESCRIPTION OF THE DRAWINGS The implementation, features, and advantages of the invention will be further described in conjunction with the embodiments.

detailed description

The specific embodiments, structures, features and functions of the invention will be described in detail below with reference to the accompanying drawings and preferred embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in Fig. 1, Fig. 1 is a schematic structural view of a preferred embodiment of the invention unmanned aerial vehicle. In the present embodiment, the unmanned aerial vehicle 100 includes, but is not limited to, an unmanned aerial vehicle main body 1, a plurality of rotors 2 (for example, four rotors), a plurality of tripods 3 (for example, two tripods), Telescopic rod 4 and imaging device 5.

The UAV main engine 1 is connected to the rotor 2, the stand 3 and the telescopic rod 4. Specifically, the stand 3 and the telescopic rod 4 are disposed below the UAV main unit 1. The imaging device 5 is disposed at an end of the telescopic rod 4.

The rotor 2 provides flight power to the unmanned aerial vehicle 100.

The stand 3 is used to provide support for the UAV 100 to dock on the ground.

The telescopic rod 4 can be telescoped to adjust the relative position between the camera 5 and the rotor 2 (as shown in FIG. 2). Specifically, the UAV host 1 controls the telescopic rod 4 to extend a predetermined distance so that the photographing device 5 is away from the rotor 2 by a predetermined distance (for example, 20 meters or 30 meters).

Each rotor 2 includes a support arm 20, a motor 22, and a propeller 24 that is driven by a motor 22. One end of the support arm 20 is connected to the UAV main body 1 , the other end of the support arm 20 is fixed to the motor 22 , and the propeller 24 is disposed above the motor 22 .

The photographing device 5 is used for tracking a live image of a photographing target in the air. The target refers to a human body or a specific object (for example, a car, a soccer field, etc.). Further, in other embodiments, the camera device 5 is a 360 degree panoramic camera or a 360 degree rotating camera.

The UAV host 1 is configured to control the photographing device 5 to track a real-time image of the target in the air according to the initial target image.

In the present embodiment, since the propeller 24 of the rotor 2 generates noise when the UAV 100 is flying, in order to prevent the noise of the propeller 24 from affecting the photographing effect, the telescopic rod 4 is extended downward before the photographing device 5 is operated. The preset distance to reduce the noise of the propeller 24 has an adverse effect on the shooting.

The unmanned aerial vehicle 100 is a small unmanned aerial vehicle operated by a radio remote control device or a self-program control device, such as an unmanned fixed-wing aircraft, an unmanned multi-rotor aircraft, a small unmanned aerial vehicle such as an unmanned wing aircraft. .

The UAV 100 further includes a battery 6 that is coupled to the UAV host 1 to provide power to the UAV host 1. Furthermore, the battery 6 is also connected to the rotor 2 to provide power to the rotor 2.

The battery 6 can be mounted inside or outside the UAV main unit 1. In other embodiments, the battery 6 may also be disposed on the support arm 20 on which the rotor 2 is disposed. The battery may be, but not limited to, a solar cell, a rechargeable battery (eg, a lithium ion battery), or the like.

As shown in Fig. 3, Fig. 3 is a schematic view showing the internal structure of a preferred embodiment of the unmanned aerial vehicle main unit 1 of the invention unmanned aerial vehicle. In the present embodiment, the UAV host 1 includes, but is not limited to, a target setting unit 202, a flight control unit 203, and a communication unit 204. The UAV host 1 is also connected to the imaging device 5 and the battery 6.

The target setting unit 202 is configured to set an initial target image. Specifically, the target setting unit 202 controls the photographing device 4 to take an initial image taken by an aiming target (for example, a human body or a specific object), which is an initial target image, before starting aerial photography.

The flight control unit 203 controls the UAV 100 to track the target in real time in the air according to the initial target image and to perform real-time shooting of the target by the photographing device 4.

The communication unit 204 is a wireless communication interface with remote wireless communication function, for example, a communication interface supporting communication technologies such as GSM, GPRS, CDMA, WiMAX, FDD-LTE, TD-LTE, and the display with the remote end. The terminal (not shown) performs wireless communication. The communication unit 204 transmits the real-time image of the target to the remote display terminal, and displays the display terminal Show.
