During the rotation of the double-tube frame 134, the double-tube frame 134 supports the rotation of the vertical rod 9, enabling the rotation of the vertical rod 9 to be stable. Thus, during the process of the drone surveying and mapping the photovoltaic area at high altitude, the problem of unstable center of gravity during the rotation of the frame rod 4 causing jitter in the shooting of the surveying and mapping module 7 is avoided.
