AERIAL PHOTOGRAPHY BY MODEL PLANE

摘要

PURPOSE:To obtain easily an aerial photograph in safety and at low cost by fitting two generators horizontally to the nose of a model plane and reducing oscillation. CONSTITUTION:This model plane has tow generators, but flies with only one generator. Further, an automatic stabilizer allows a horizontal fly without any external influence. Therefore, the safety is high. Its controllable distance range is up to 200m high and 300m away from a pilot in any direction and the distance of photography is made longer by increasing the number of pilots. Vertical and slanting photographs are obtained as finished aerial photographs. The flight altitude is read on an optical distance measuring instrument and a desired altitude is held through the atuomatic stabilizer. Thus, aerial photographs are obtained easily in safety and at low cost.
