Abstract
Recently, the needs of observation UAVs (Unmanned Aerial Vehicle), such as unmanned fixed-winged aircraft, unmanned helicopters and multi-rotor aircraft, have increased instead of the manned aircraft. It is expected that the UAVs are useful for aerial image acquisition, monitoring of disaster areas and so on. Especially unmanned helicopters can observe hovering in the air, that is a strong point for observation. Therefore, in AIST and NRIFD, the unmanned helicopter system for disaster prevention is being developed. This time, in order to measure the position and attitude of the unmanned helicopter or monitoring equipment, the position and attitude measuring method with stereo vision was developed. Using the method, the unmanned helicopter can know its local position and attitude with a high degree of accuracy. It and a high precision GPS can complement. In this paper, the position and attitude measuring method with stereo vision and the experimental results are described.
