The invention proposes a drone.

Referring to FIG. 1 to FIG. 2, the unmanned aerial vehicle of the present embodiment includes a fuselage 10, and the inside of the fuselage 10 is provided with at least one duct 11 extending through the upper and lower sides of the fuselage 10, and at least one of the ducts 11 is provided in each of the ducts 11 a propeller 12, the body 10 is provided with an image capture device (not shown), the image capture device includes a plurality of cameras 13, the camera 13 is fixed to the surface of the body 10, the camera 13 Used to capture images around the body 10.

The UAV of the present embodiment places the propeller 12 in the duct 11, which can effectively protect the propeller 12 and prevent the propeller 12 from being damaged due to the drone falling or touching other objects during the flight. The propeller 12 is more versatile in the passage 11 than the existing cantilever propeller, and is also less susceptible to airflow, and the flight process is more stable. The duct 11 may be cylindrical. More preferably, the duct 11 may be an inverted cone or a truncated cone. The diameter of the opening of the duct 11 on the upper surface of the fuselage 10 should be larger than that under the fuselage 10. The opening diameter of the surface helps to adjust the flow velocity of the surface of the fuselage 10, further improving the stability of the fuselage during flight.

Further, a plurality of cameras 13 on the body 10 are disposed around the periphery of the body 10 to ensure image collection efficiency and quality. A plurality of cameras 13 are fixed on the surface of the body 10, and each camera 13 collects images in a fixed direction. The camera 13 in multiple directions on the 10 can collect image information of each direction of the upper and lower sides of the body 10, and can complete image collection in all directions without rotating. When the existing UAV collects images, it is necessary to control the pan/tilt to drive the camera to rotate. The technical solution of the embodiment effectively reduces the operation complexity. Further, the existing drone needs to constantly adjust the direction of the camera through the pan/tilt suspended from the lower part of the drone. The rotation of the external camera causes the center of gravity and aerodynamic layout of the drone to change. When the airflow changes, the drone is likely to be out of control, and the camera 13 in this embodiment is all fixed on the body 10, cannot be rotated and moved, and only needs to adjust the focal length and the like without affecting the center of gravity and shape of the drone. Operation, so it is not susceptible to interference and high stability.

Preferably, a protective device (not shown) having the same number as the camera 13 is disposed on the body 10. The protective device has an accommodation space (not shown) inside, and the receiving space is provided with an extension. To a photographing window (not identified) of the surface of the body, the camera 13 is disposed in the accommodating space, and a lens (not labeled) of the camera extends from the photographing window to a surface of the body.

At least three first cameras 13A are uniformly disposed at an angle in the horizontal direction around the body 10, and preferably, six first cameras 13A are provided. More preferably, the top of the body 10 is provided with at least one second camera 13B for collecting the top image of the body 10, and the bottom of the body 10 is provided with at least one third for collecting the bottom image of the body 10. Camera 13B.

The camera 13 of the present invention does not need to be rotated, and thus can be hidden inside the body 10, that is, does not affect image acquisition, and can also reduce the influence on the aerodynamic layout and prevent the influence of the airflow during the flight. Preferably, the front end of the lens of the camera 13 is flush with the surface of the body 10, and the surface of the body 10 may be slightly protruded to enlarge the angle of view of the lens, and may be completely recessed into the inner side of the surface of the body 10 without affecting the angle of view. To protect the lens.

Preferably, the lens is a wide-angle lens.

The existing fisheye lens has a large viewing angle, and 360° framing can be realized by using three fisheye lens. Therefore, at least three first cameras 13A are disposed on the body 10 of the drone in the horizontal direction. However, the image quality of the fisheye lens is poor, and the picture is severely deformed. Therefore, in order to ensure the picture quality, a general wide-angle lens should be used. Considering the wide angle lens of the existing image quality, the lateral angle of the image is 30°~70°. A better imaging effect can be achieved by using the six first cameras 13A. The first camera 13A is disposed in the same plane, and the images collected by the plurality of first cameras 13A are also in the same plane, which facilitates splicing and post-processing of the images. Although increasing the number of the first cameras 13A contributes to an improvement in the imaging effect, it also increases the cost and the overall weight, so the present embodiment sets six first cameras 13A in the horizontal direction. Further, since the upper part of the fuselage 10 is the sky and the lower part is the ground during the flight, the quality of the image directly above and below the collected body 10 is not high, so in the present embodiment, in the upper part of the body 10. Each of the lower portion and the lower portion are respectively provided with a second camera 13B and a third camera 13C. The number of the second camera 13B and the third camera 13C may be increased or decreased depending on the specific situation, and the present invention is not limited thereto.

Preferably, the ducts 11 are uniformly disposed on the body 10 at an angle. The number of the ducts 11 is six or eight, and each of the ducts 11 is provided with at least one propeller 12 for power supply via a propeller holder 14. More preferably, the body 10 has a circular cross section, and the surface of the body 10 is streamlined.

In this embodiment, the body 10 of the present embodiment has a disk shape as a whole, and the upper surface of the upper surface of the body 10 is slightly convex upward, and the lower surface of the body 10 is a plane or an approximately flat surface. In each longitudinal section of the fuselage 10, the length of the upper surface of the fuselage 10 should be greater than the length of the lower surface. This design ensures that when the airflow passes through the surface of the fuselage 10, the airflow velocity in the upper portion of the fuselage 10 is greater than the velocity of the bottom airflow. It then provides a certain lift for the drone, which helps to improve the stability of the drone during flight. The upper and lower surfaces of the fuselage 10 are streamlined, which can reduce the air resistance.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the invention, and the equivalent structural transformation, or direct/indirect use, of the present invention and the contents of the drawings are used in the inventive concept of the present invention. It is included in the scope of the patent protection of the present invention in other related technical fields.
