The invention relates to the field of topographic survey, in particular to topographic survey equipment based on Beidou navigation. According to the technical scheme, the topographic survey equipment based on Beidou navigation comprises an unmanned aerial vehicle body, flight propellers and the like; a plurality of flight propellers are fixedly connected to the side wall of the unmanned aerial vehicle body. After the unmanned aerial vehicle body lifts off, all the electric actuators are controlled to contract, the corresponding supporting legs are synchronously driven to move upwards, blocking of the supporting legs to the scanning view of the camera is effectively reduced, and when the unmanned aerial vehicle body returns and lands, the electric actuators extend to the length of four fifths of the total extension amount of the electric actuators and synchronously drive the supporting legs to move downwards; the two arc rods are synchronously driven to rotate in the opposite directions, meanwhile, each arc rod pulls one shielding curtain, the two shielding curtains are unfolded downwards to shield a camera, flying dust is effectively intercepted, and the situation that when an unmanned aerial vehicle body gets close to a parking apron, the flying dust makes direct contact with a camera lens is reduced.
本发明涉及地形测量领域,尤其涉及一种基于北斗导航的地形测量设备。技术方案为:一种基于北斗导航的地形测量设备,包括有无人机本体和飞行桨等;无人机本体侧壁上固接有多个飞行桨。本发明通过无人机本体升空后,控制所有的电动执行器收缩,同步带动相应的支腿向上运动,有效减少支腿对摄像机扫描视野的阻挡,无人机本体返航降落时,电动执行器伸长至其总伸长量的五分之四的长度,同步带动支腿向下运动,同步带动两个弧杆的往相反方向转动,同时,每个弧杆各拉动一片遮挡帘,两个遮挡帘向下展开,对摄像机进行遮挡,有效拦截扬尘,减少无人机本体靠近停机坪时,扬尘直接与摄像机镜头接触。
