Abstract
We propose 3D measurement system for the quad rotor helicopter. In this system, 3D measurement of the structure in the surrounding becomes possible by installing the laser range finder (LRF) on the airframe, and controlling maneuver automatically. Best maneuver and the control techniques are examined. The control was difficult though it had made to three dimensions last time by the maneuver that used the precession movement. LRF is set up by turning sideways to control easily this time.
