[0002] A multi-view stereo aerial photography device is a type of equipment used for drone photography. It is mainly used to acquire stereo images from multiple perspectives. The design of this device allows the drone to shoot from different angles and directions, obtaining more perspectives and detailed information. By adjusting the included angle, precise control of the shooting angle can be achieved. It is suitable for various complex shooting scenarios. In addition, the device has a simple structure, which can reduce the weight of the drone and improve shooting efficiency and flexibility.

[0003] As disclosed in the authorization announcement number CN209037873U, an oblique photography aerial camera device includes a drone. Two connecting blocks are fixedly installed on the bottom of the drone. The same first fixing plate is fixedly installed on the bottom of both connecting blocks. Three airbags are fixedly installed on the bottom of the first fixing plate. The same second fixing plate is fixedly installed on the bottom of each of the three airbags.

[0004] Although it enables tilting of the lens for photography by driving the first and second stepper motors, expanding the shooting range, enhancing flexibility and buffering effect, it does not cause lens vibration, and does not produce shaking during shooting, thus not affecting the lens shooting.

[0005] However, this does not solve the problem that existing stereo aerial photography devices generally lack multiple shock absorption and buffer protection during use, are not convenient for multi-angle rotation and adjustment for shooting, affect the shooting range of the stereo aerial photography device, and are easily damaged by external impacts, thus affecting the shooting effect of the stereo aerial photography device.

[0007] To address the technical problems mentioned in the background section, some embodiments of this application provide a multi-view stereo aerial photography device for unmanned aerial vehicles (UAVs), including a connecting plate and supporting legs. Four sets of supporting legs with equal spacing are installed on the outer wall of the connecting plate. A protective cover is provided outside the connecting plate.

[0010] Furthermore, a second motor is provided inside the first support frame, and the second motor extends to the outside of the first support frame. A first rotating shaft is installed at the output end of the second motor, and the first rotating shaft is connected to the second support frame.

[0011] Furthermore, a third motor is installed inside the third support frame, and the third motor extends to the outside of the third support frame, with a second rotating shaft installed at the output end of the third motor.

[0012] Furthermore, a fourth support frame is provided on the outside of the third support frame away from the third motor, and the fourth support frame is connected to the second rotating shaft. A fixing plate is installed at the bottom end of the fourth support frame.
