Document Type and Number:
WIPO Patent Application WO/2018/090943
Kind Code:
A1
Abstract:
An unmanned aerial vehicle for an underwater photographing comprises a fuselage (200), a photographing device (300), a height measurement device (290), a driving device (260), an attitude control device, and a photographing device balance detection device. When the unmanned aerial vehicle moves on a water level, the photographing device balance detection device detects that an optical axis of the photographing device (300) does not form a right angle with a photographed object, and the attitude control device on the photographing device (300) changes an angle between the photographing device (300) and the unmanned aerial vehicle by means of the driving device (260), so as to compensate the change of the optical axis of a lens module, thereby ensuring a good photographing visual angle.
