The invention relates to an airborne shooting device of an unmanned aerial vehicle, in particular to an airborne air-photo image-stabilizing cloud deck of the unmanned aerial vehicle. A cross beam is installed on a fixing rod of the unmanned aerial vehicle, and a first flat plate with a middle hole is disposed on the cross beam. A horizontal rotating driving steering engine is arranged on a first frame and connected with the first flat plate through a horizontal transmission mechanism, the counter force of the first flat plate drives the first frame to rotate horizontally, and a horizontal angle detection potentiometer can penetrate through the middle hole of the first flat plate in a relatively rotating mode to be fixedly connected on the first frame. A second frame is rotatably disposed on the first frame through horizontal shafts on both sides of the second frame, the horizontal shaft on one side of the second frame is connected with a perpendicular rotating driving steering engine arranged on the first frame through a perpendicular transmission mechanism, and the horizontal shaft on the other side of the second frame is connected with a perpendicular angle detection potentiometer. The second frame is driven by the perpendicular rotating driving steering engine to rotate perpendicularly and rotates horizontally along with the first frame. The airborne air-photo image-stabilizing cloud deck of the unmanned aerial vehicle is good in shock absorption effect, large in driving torque and stable in rotating speed.
