Detailed Description of the Embodiments

[0028] The following will specifically describe the preferred embodiments of the present utility model in conjunction with the drawings. The drawings form a part of the present utility model and are used together with the embodiments of the present utility model to explain the principle of the present utility model, rather than to limit the scope of the present utility model.

[0029] Embodiment 1

[0030] A specific embodiment of the present utility model, as Figure 1 , Figure 2 shown, discloses a camera viewing angle adjustment structure, including a camera mounting member 1, a limiting member 2, a connecting member 3, a fastening member 4 and a rotating shaft 5.

[0031] In this embodiment, one side of the camera mounting member 1 is fixedly installed with a camera 7, and the other side is installed with a limiting member 2 and a connecting member 3.

[0032] In this embodiment, the rotating shaft 5 includes a first rotating shaft 51 and a second rotating shaft 52. The first rotating shaft 51 and the second rotating shaft 52 are arranged parallel to each other, and the position of the first rotating shaft 51 is fixed.

[0033] In this embodiment, the first rotating shaft 51 and the second rotating shaft 52 are respectively arranged through both ends of the camera mounting member 1. Optionally, one end of the camera mounting member 1 is hinged to a support member fixed on the using device through the first rotating shaft 51, and can also be hinged to one end of a limiting member 2 fixed on the using device through the first rotating shaft 51, so that the positions of the first rotating shaft 51 and the fixed end of the camera mounting member 1 are fixed. The other end of the camera mounting member 1 is rotatably connected to a connecting member 3 through the second rotating shaft 52.

[0034] Preferably, the plane where the first rotating shaft 51 and the second rotating shaft 52 are located is perpendicular to the optical axis of the camera 7 to ensure that the tilt angle of the camera 7 is the same as the tilt angle of the camera mounting member 1.

[0035] In this embodiment, a linear chute 21 is provided on the limiting member 2. Both ends of the linear chute 21 are open and the cross-section is U-shaped, and the inner cavity of the linear chute 21 is a limiting slideway 22. Preferably, the limiting slideway 22 is perpendicular to the first rotating shaft 51 and the second rotating shaft 52; limiting through grooves 23 are symmetrically opened on both sides of the linear chute 21, and the limiting through grooves 23 are parallel to the limiting slideway 22.

[0036] In this embodiment, the connecting member 3 is a rod body with through holes provided at both ends. One end of the connecting member 3 is rotatably connected to the camera mounting member 1 through the second rotating shaft 52, and the other end is an adjusting end 31; the adjusting end 31 is located in the linear chute 21, and the linear chute 21 guides both sides of the adjusting end 31 to move linearly on the limiting slideway 22, so that the second rotating shaft 52 rotates around the first rotating shaft 51, thereby playing a role in adjusting the tilt angle of the camera mounting member 1.

[0037] In this embodiment, the fastener 4 is used to fix the position of the adjusting end 31 in the linear chute 21, thereby fixing the angle of the camera mounting member 1. As Figure 2 shown, the fastener 4 includes a positioning pin 41 and a fastening nut 42.

[0038] Optionally, one end of the positioning pin 41 is a screw head, the middle is a smooth rod, the diameter of the smooth rod matches the through hole at the adjusting end 31, and the other end of the positioning pin 41 is provided with a thread. The positioning pin 41 passes through the limiting through grooves 23 on both sides of the linear chute 21 and the through hole at the adjusting end 31. Due to the limiting effect of the two limiting through grooves 23 on both ends of the positioning pin 41, the moving path of the adjusting end 31 can be further limited within the limiting slideway 22. When the positioning pin 41 is moved in the limiting through groove 23 to make the tilt angle of the camera mounting member 1 in the required position, the fastening nut 42 is tightened so that the screw head and the fastening nut clamp and fix on the two side walls of the linear chute 21 to fix the position of the adjusting end 31 on the limiting slideway 22, thereby playing a role in fixing the tilt angle of the camera mounting member 1.

[0039] In this embodiment, both ends of the limiting through groove 23 can limit the angle adjustment range of the camera mounting member 1. Preferably, when the positioning pins 41 are respectively located at both ends of the limiting through groove 23, the inclination angles of the camera mounting member 1 are 0° and 90° respectively. Thus, when the positioning pins 41 drive the adjustment end 31 to move in the limiting slideway 22, the inclination angle of the camera mounting member 1 can be adjusted and positioned between 0° and 90°.

[0040] For the UAV camera viewing angle adjustment structure of this embodiment, by setting one end of the connecting member 3 as a movable adjustment end 31, when the adjustment end 31 moves, the connecting member 3 can exert a driving force or a pulling force on the second rotating shaft 52, so that the camera mounting member 1 rotates around the first rotating shaft 51, playing a role in adjusting the inclination angle of the camera, and further stably fixing the camera at the required viewing angle position through the fastener 4. The UAV camera viewing angle adjustment structure of this embodiment has few components, a simple structure, and accurate camera angle adjustment. In addition, by fixing the camera viewing angle in a fastening manner, the viewing angle is more stable and not prone to change.

[0041] Furthermore, the limiting member 2 further includes a plurality of limiting portions 24. When the adjustment end 31 is located at the position of the limiting portion 24, the camera mounting member 1 is located at a preset angle.

[0042] Furthermore, the limiting portions 24 are arranged in the two limiting through grooves 23. Preferably, the limiting portion 24 is an arc groove matching the outer diameter of the positioning pin 41. When the positioning pin 41 moves to the position of the limiting portion 24, the side wall of the arc groove plays a role in stopping the positioning pin 41, and the positioning pin 41 is stuck in the arc groove by the action of gravity, so that the camera mounting member 1 can be conveniently and accurately located at the preset inclination angle.

[0043] Furthermore, the preset inclination angles of the camera mounting member 1 at least include 0°, 30°, 45°, and 60°. Since these inclination angles are commonly used, the camera viewing angle can be adjusted more quickly and accurately. The position of the limiting through groove 23 can be determined by actually measuring the angle of the camera mounting member 1, or can also be determined by calculation. Due to the simple structure of this embodiment, the positions of the limiting through groove 23 on the limiting member 2 when the inclination angles of the camera mounting member 1 are 0°, 30°, 45°, and 60° respectively can be determined through simple trigonometric function calculations. The positioning is simple, the inclination angle adjustment is accurate, and there is high consistency.

[0046] Such as Figure 3As shown in the figure, in this embodiment, the camera array device includes a support member 6, which is a flat support platform. A plurality of camera viewing angle adjustment structures are evenly arranged in a circumferential array, and a camera 7 is fixedly installed on each camera viewing angle adjustment structure.

[0047] Optionally, the first rotating shaft 51 and the limiting member 2 are respectively fixed on the support member 6. A plurality of mounting threaded holes are provided on the support member 6 for fixedly connecting with the limiting member 2 and the body of the using device. In order to reduce the weight of the support member 6, waist-shaped holes are also provided on the support member 6. In this embodiment, the support member 6 is a flat plate in the shape of a regular octagon, and a pair of lug ears are provided on each side of the regular octagon. Mounting through holes are provided on the lug ears for arranging the first rotating shaft 51. Obviously, the support member 6 is not limited to a regular octagon, and can also be a non-regular octagon. According to the actual need of setting the number of cameras, the support member 6 can be set as a polygon such as a hexagon or a decagon, or even a circle or an ellipse, etc., all of which can achieve the invention purpose of this application.

[0048] Optionally, the first rotating shaft 51 can also be fixed on the limiting member 2, and the limiting member 2 is fixed on the support member 6.

[0049] The camera array device of this embodiment can achieve a 360° panoramic view around the device by arranging a camera array on the support member 6. At the same time, due to arranging the camera array through the camera viewing angle adjustment structure of Embodiment 1, it can not only freely adjust the viewing angles of multiple cameras, with a simple structure and low cost, but also improve the consistency and stability of the camera angles, ensuring the need for generating high-quality 360° panoramic images through the image stitching algorithm; in addition, the viewing angle of each camera can be independently adjusted, improving the flexibility of the device.

[0050] Embodiment 3

[0051] This embodiment discloses a drone, which has the camera array device of Embodiment 2, including a drone body, a camera 7 and the camera array device of Embodiment 2. The camera 7 is fixed on the camera mounting member 1, and the support member 6 is fixed on the drone body, and can be horizontally fixed at the bottom of the body, or can also be fixed at other parts of the body according to needs. The drone of this embodiment can capture 360° panoramic images from different angles and spectral ranges by fixedly mounting the camera array device of Embodiment 2 at the bottom of the drone body, thereby obtaining richer, more detailed and accurate data, and can be widely used in fields such as agricultural monitoring, topographic surveying, urban monitoring, environmental monitoring and search and rescue.
