Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle tilt photography, and more specifically, to a military low-altitude aerial survey unmanned aerial vehicle tilt photography device. Background Art

[0002] Oblique photography is a new technology that has gradually developed in the field of drone mapping in recent years. By synchronously collecting images from one vertical, four oblique, and five different perspectives, rich high-resolution textures of the top and side views of buildings can be obtained. It can not only truly reflect the ground conditions and obtain object texture information with high precision, but also generate a real three-dimensional city model through advanced positioning, fusion, modeling and other technologies. UAV oblique photography devices are also used for low-altitude aerial surveys in military projects.

[0003] Most of the existing military low-altitude aerial survey UAV oblique photography devices use five photographic devices to shoot objects at multiple angles at a certain installation angle, so as to obtain true three-dimensional image data of the objects. Most of the photographic devices are connected to the photographic devices through screws. When not conducting aerial surveys, in order to facilitate the UAV to do other work, the photographic equipment needs to be disassembled. In the process of disassembly, multiple screws need to be removed. Since the screws are small and easy to lose, it takes a lot of time to unscrew multiple screws at the same time. The difficulty of disassembly is relatively large, resulting in the efficiency of disassembly and assembly of the photographic equipment. In addition, since the photographic equipment is exposed to the outside, rainwater is easy to fall on the photographic equipment, which can easily cause damage to the photographic equipment.
