The invention relates to the technical field of unmanned aerial vehicles. The invention aims to provide an automatic deviation correcting device for an oblique photogrammetry yaw angle of an unmanned aerial vehicle. The automatic deviation correcting device comprises an unmanned aerial vehicle body and an adjusting mechanism, the adjusting mechanism comprises at least three electric control telescopic components, the electric control telescopic components are annularly and evenly distributed around the center of the swing plate, and the upper end and the lower end of each electric control telescopic component are connected with the fixing frame and the swing plate through a first universal spherical hinge respectively. The adjusting mechanism further comprises a spring traction set arranged between the fixing frame and the center of the swing plate. The system further comprises a calculation chip and a control chip. According to the invention, the adjusting plate can be quickly and sensitively adjusted at any angle according to the flight attitude of the unmanned aerial vehicle main body, so that the aerial camera is kept at a standard shooting position, the difficulty of later image processing is reduced, meanwhile, the spring traction group is adopted to pull the adjusting plate, the load of the electric control telescopic component is reduced, and the service life is prolonged.
本发明涉及无人机技术领域。目的在于提供一种无人机倾斜摄影测量偏航角自动纠偏装置,包括无人机本体,调节机构;所述调节机构包括至少三根电控伸缩部件,所述电控伸缩部件绕摆动板的中心呈环形均匀分布,电控伸缩部件的上下两端分别通过一个第一万向球铰与固定架和摆动板连接;所述调节机构还包括设置在固定架与摆动板中心之间的弹簧牵拉组;还包括计算芯片和控制芯片。本发明能够快速、灵敏的根据无人机主体的飞行姿态实现调节板任意角度的调节,使得航拍摄像头保持标准拍摄位,降低了后期图像处理的难度,同时采用弹簧牵拉组对调节板进行牵拉,降低了电控伸缩部件的负荷,延长了使用寿命。
