[0002] Aerial photogrammetry is a technical means of using photographic equipment carried by aircraft such as airplanes to photograph the ground from the air in order to obtain geographic information and topographic data. It has a wide range of applications in many fields such as urban planning, land resource management, geological exploration, and environmental monitoring. High-quality aerial photogrammetry data is crucial for accurate mapping, monitoring environmental changes, and engineering design and evaluation. With the rapid development of aerial photography technology, the resolution of cameras has continued to improve, from standard definition to high definition to ultra-high definition, which enables cameras to capture clearer and more detailed images. However, high-resolution cameras also have higher requirements for stability. Slightest shake may cause image blur or distortion. Therefore, a reliable aerial photogrammetry camera bracket is needed to ensure that the camera remains stable during operation and give full play to its high-quality image advantages.
[0003] However, the existing aerial photogrammetry camera fixed bracket cannot achieve flexible movement and adjustment of the camera, which will greatly limit the coverage and flexibility of aerial photogrammetry. In some complex terrain or areas with dense buildings, it may not be possible to obtain comprehensive image data. Utility Model Content

[0024] In this embodiment, when the position of the camera body 304 needs to be flexibly moved and adjusted, the depth direction of the camera body 304 is first adjusted through the provided adjustment mechanism 2, and the first motor 204 is started. The operation of the first motor 204 causes the threaded rod 205 to rotate, thereby driving the crossbeam 206 to slide in the first slide groove 203. When it reaches the appropriate position, the first motor is turned off, and then the lateral direction of the camera body 304 is adjusted. The second motor 208 is started. The operation of the second motor 208 causes the gear 209 to rotate, thereby driving the adjustment rack 211 meshed with the gear 209 to slide laterally in the second slide groove 210, thereby driving the slider 213 fixedly connected to the adjustment rack 211 to slide in the third slide groove 212. Since the bottoms of the two sliders 213 are fixedly connected by the connecting plate 214, they drive the rotating mechanism 3 installed at the bottom of the connecting plate to move laterally together. When the camera body 304 reaches the appropriate position, the second motor 208 is turned off, thereby achieving flexible movement and adjustment of the camera body 304, improving the coverage and flexibility of aerial photogrammetry, and obtaining comprehensive image data.
[0025] Example 2: Figure 1-Figure 5As shown, the rotating mechanism 3 includes a third motor 301, and the output end of the third motor 301 is provided with a first rotating shaft 302, the bottom of the first rotating shaft 302 is fixedly installed with a connecting disk 303, and the bottom of the connecting disk 303 is symmetrically installed with a mounting bracket 304, one side of one mounting bracket 304 is fixedly installed with a motor bracket 305, and the bottom of the motor bracket 305 is fixedly installed with a fourth motor 306, the output end of the fourth motor 306 is provided with a second rotating shaft 307, and the outer wall of the second rotating shaft 307 is provided with a camera body 308.
[0026] In this embodiment, when it is necessary to rotate the camera body 304 for angle adjustment, it is achieved through the provided rotating mechanism 3. First, the third motor 301 is started.

Since the two sliders 213 The bottom is fixedly connected by a connecting plate 214, thereby driving the rotating mechanism 3 installed at the bottom of the connecting plate to move horizontally, so that when the camera body 304 reaches the appropriate position, the second motor 208 can be turned off, thereby realizing flexible movement and adjustment of the camera body 304, improving the coverage and flexibility of aerial photogrammetry, and obtaining comprehensive image data. When it is necessary to rotate the camera body 304 for angle adjustment, it is achieved by the provided rotating mechanism 3, starting the third motor 301, and the third motor 301 works to drive the first rotating shaft 302 to rotate.
