The invention relates to a double-camera and multi-angle shooting supporting device for an unmanned aerial vehicle. The double-camera and multi-angle shooting supporting device for the unmanned aerial vehicle comprises a frame, a control device, a motor, a steering engine, a supporting shaft, a rotating stand, a limiting piece and a bolt, wherein two ends of the rotating stand are respectively hinged with two short edge pieces of the frame; the steering engine is fixed at one end of the rotating stand; the lower part of the steering engine is fixedly connected with the frame through the supporting shaft; the bolt penetrates through the frame and the supporting shaft so that the supporting shaft is located on the frame; double cameras are fixed within the frame; the top of the rotating stand is fixed at the bottom of the unmanned aerial vehicle; the control device is connected with the motor; the motor is connected with the steering engine; the limiting piece is fixed on a short edge piece of the frame and positioned on the two sides of the steering engine; the control device controls the motor; the motor drives the steering engine so that the steering engine drives the rotating stand to rotate; therefore, the double cameras can realize multi-angle shooting on the frame; and during the rotating of the rotating stand, the rotating angle of the rotating stand can be determined through the limiting piece. The double-camera and multi-angle shooting supporting device for the unmanned aerial vehicle, provided by the invention, is advantaged in that the efficiency of the double-camera and multi-angle shooting supporting device is high, the shooting angles of the cameras can be automatically controlled and adjusted, and various shooting angles are realized.
