Abstract

A two-freedom air-shooting rotary table using model airplane helicopter as carrier is prepared for using silica gel vibration attenuation material to isolate connection position between suspension support and model airplane helicopter landing gear, applying V belt driving on horizontal rotary mechanism and rope driving on vertical-rotary mechanism, utilizing round rudder disc with edge notch to drive varifocus control rod of DV machine for carrying out varifocus, utilizing model airplane remote control unit to control DV machine to rotate vertically and horizontally as well as to carry out varifocus by shooting personnel.

Description

technical field [0001] The invention relates to a two-degree-of-freedom cloud platform for aerial photography, which belongs to a controllable load platform. It is installed on a model airplane helicopter, used to carry a DV machine, and uses a remote control device for remote control for aerial photography. Background technique [0002] Aerial photography has application value in many fields. Usually, manned helicopters are used to carry photographers and equipment for aerial photography. This aerial photography method has the advantages of high flight altitude, long stay in the air, and the ability to carry large equipment, but there are problems such as high risk, high cost, and cumbersome approval procedures. . In recent years, model airplane helicopters have been used to carry small equipment, and photographers use remote control to take aerial photography on the ground according to the monitor image. This aerial photography method will have great limitations in terms...
