The invention provides a ground target for aerial photogrammetry of an unmanned aerial vehicle, and relates to the technical field of ground targets. According to the ground target, a base is rotationally connected with a first rotating disc, the first rotating disc is fixedly connected with symmetrically-distributed arc-shaped plates, the arc-shaped plate on one side is fixedly connected with symmetrically-distributed first fixing rods, a connecting plate is fixedly connected between the symmetrically-distributed first fixing rods, the symmetrically-distributed first fixing rods are rotationally connected with a rotating rod, and the rotating rod is fixedly connected with a rotating plate; the side, away from the rotating rod, of the rotating plate is fixedly connected with symmetrically-distributed fixing columns, the rotating plate is provided with a target, and the rotating rod is rotationally connected with symmetrically-distributed rotating discs. Through the characteristic that the rotating disc and the first heavy block are perpendicular to the ground, the rotating plate and the target are made to adapt to the ground with any inclination angle, the rotating plate and the target are made to be parallel to the horizontal plane, and through cooperation of the first U-shaped frame and the rotating plate, the rotating plate is fixed to the position parallel to the horizontal plane; the accuracy of the takeoff and landing position and the photographing mark position of the unmanned aerial vehicle is ensured.
本发明提供了一种用于无人机航空摄影测量的地面标靶,涉及地面标靶技术领域。本发明的地面标靶,底座转动连接有第一转动盘,第一转动盘固接有对称分布的弧形板,一侧的弧形板固接有对称分布的第一固定杆,对称分布的第一固定杆之间固接有连接板,对称分布的第一固定杆转动连接有转杆,转杆固接有转动板,转动板远离转杆的一侧固接有对称分布的固定柱,转动板设置有标靶,转杆转动连接有对称分布的转盘。本发明通过转盘和第一重块垂直于地面的特性,使转动板和标靶适应于任何倾斜角度的地面,并使转动板和标靶与水平面平行,通过第一U形架与转动板的配合,将转动板固定至与水平面平行的位置,以保证无人机起落位置和摄影标记位置的准确性。
