PURPOSE: A 3D image photographing system of an object through multi direction aerial photographing is provided to obtain side image information at once by aerial flight one time, thereby minimizing additional manufacturing costs of a digital map. CONSTITUTION: A computation unit(200) comprises the following units. A screw counter(210) counts RPM(Revolution Per Minute) of a screw. A GPS receiver(270) senses GPS coordinates. A GPS confirming module(230) confirms the current position of an aircraft. A data classifying module(250) inputs each photographing angle information as photographing image data.
