Description

Technical Field

[0001] The invention relates to the technical field of windows, and in particular to a multi-angle aerial survey device based on an aerial survey unmanned aerial vehicle. Background Art

[0002] UAV aerial survey is a powerful supplement to traditional aerial photogrammetry. It is flexible, efficient, precise, low-cost, widely applicable, and has a short production cycle. It has obvious advantages in the rapid acquisition of high-resolution images in small areas and areas with difficult flight. With the development of UAV and digital camera technology, digital aerial photography technology based on UAV platforms has shown its unique advantages. Now, aerial survey photography no longer only meets the requirements of vertical photography, but also requires the collection of images from other angles to meet the analysis of comprehensive data.

[0003] The traditional drone aerial survey camera installation structure is relatively simple and can only fix a single lens. A few multi-lens brackets can only be placed in some fixed positions. It is difficult to meet the needs of multi-lens and multi-angle measurements in different positions, and the lenses cannot be fixed and adjusted arbitrarily. At the same time, the current camera mounting brackets usually lack structures to protect the camera. When landing, they usually have hard contact with the ground and lack a buffering effect, which can easily cause the camera structure to be subjected to greater vibrations, affecting subsequent use.

[0018] 3. When in use, the support column at the bottom can be rotated open, and then the beveled tooth plate can be removed to release the buffer assembly, and then the fixed spring drives the moving block to move, so that the connecting plate is pushed out of the connecting shaft, and then the beveled tooth plate is reinstalled. At this time, when an accident occurs or the landing speed is high, the impact force can drive the connecting plate to squeeze the moving block, and then the moving block squeezes and compresses the fixed spring to achieve buffering. At the same time, the action of the beveled tooth plate can effectively prevent the moving block from rebounding after being compressed, thereby effectively maintaining the stability of the device.
