Therefore, they cannot be understood as limitations on the present invention.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] The following is combined with Figure 1-5 The utility model is further described.

[0023] In order to solve the problems existing in the background technology, the present application proposes the following technical solution: an aerial remote sensing photogrammetry device, including an unmanned aerial vehicle body 1 and a camera 3 arranged under the unmanned aerial vehicle body 1.

[0024] In a further design, a mounting seat 14 is detachably fixedly connected to the bottom of the drone body 1, a support frame 13 is provided below the mounting seat 14, and a rack 2 is fixedly connected to the outside of the support frame 13. The rack 2 is a U-shaped structure for installing a camera 3, and a pin 4 is rotatably connected inside the rack 2. The pin 4 is fixedly connected to the camera 3, so it is convenient to realize the rotation adjustment of the camera 3. In order to facilitate the driving of the pin 4 to rotate, a driving member for driving the pin 4 to rotate is also provided on the outside of the rack 2.

[0025] Specifically, the driving member includes a fixing frame 9 fixedly connected to the outside of the frame 2 and a first motor 10 fixedly connected to the outside of the fixing frame 9. The driving shaft of the first motor 10 and the outside of the pin shaft 4 are fixedly connected with a first gear 11. A toothed belt 12 is provided between two adjacent first gears 11. Therefore, the first motor 10 drives the first gear 11 to rotate, and then the toothed belts 12 are engaged with each other, so that the pin shaft 4 can be driven to rotate.

[0026] In order to protect the camera 3, a synchronization plate 5 is fixedly connected to the outside of the pin shaft 4, and a buffer plate 6 is fixedly connected to the outside of the synchronization plate 5. The buffer plate 6 is an arc-shaped structure, and a spring 7 is fixedly connected to the outside of the buffer plate 6. A buffer bag 8 is fixedly connected to the outside of the spring 7. In order to increase the buffering effect, the buffer bag 8 is filled with a damping buffer 19.

[0027] The above technical solution is explained as follows: when the drone body 1 returns, it only needs to control the first motor 10 to rotate again, so that the camera part of the camera 3 is adjusted upward. Figure 4 As shown in the figure, the arc plate and the buffer bag 8 can protect the camera 3; therefore, even if the camera 3 touches the ground due to an accident, the camera 3 can be protected and buffered by the buffer bag 8, the buffer plate 6 and the spring 7. At the same time, by adjusting the camera 3 to face upward, the head area of ​​the camera 3 can also be fully protected.

[0028] In a further design, a second motor 15 is fixedly connected to the outside of the mounting base 14, a rotating rod 17 is rotatably connected to the bottom of the mounting base 14, the rotating rod 17 is fixedly connected to the support frame 13, a driving shaft of the second motor 15 is fixedly connected to a third gear 18, and the outside of the rotating rod 17 is fixedly connected to the third gear 18. The second motor 15 drives the second gear 16 to rotate, the second gear 16 drives the third gear 18 to rotate, and then drives the support frame 13 and the frame 2 to rotate, thereby completing the adjustment of the circular angle.

[0029] In order for those skilled in the art to fully understand the technical solution, this embodiment is summarized as follows:

[0030] When in use, the mounting base 14 is mounted on the bottom of the drone body 1, and then the drone is controlled to take off, and then the ground is photographed and measured by the camera 3;

[0031] At the same time, the first motor 10 can be controlled to drive the first gear 11 to rotate, and then the camera 3 can be driven to rotate through the pin shaft 4 to complete the adjustment of the tilt angle of the camera 3, and then the second motor 15 can be started to drive the second gear 16 to rotate, and the second gear 16 can drive the third gear 18 to rotate, and then drive the support frame 13 and the frame 2 to rotate, so as to complete the adjustment of the circumferential angle;

[0032] When the drone body 1 returns, it is only necessary to control the first motor 10 to rotate again so that the camera part of the camera 3 is adjusted upward. Figure 4 As shown in the figure, the arc plate and the buffer bag 8 can protect the camera 3;

[0033] Therefore, even if the camera 3 contacts the ground due to an accident, the camera 3 can be protected and buffered by the buffer bag 8, the buffer plate 6 and the spring 7. At the same time, the head area of ​​the camera 3 can be fully protected by adjusting the camera 3 to face upward.
