PROBLEM TO BE SOLVED: To improve the accuracy of distance measurement of a stereo camera with an inexpensive configuration and mounted on an aircraft.SOLUTION: A stereo distance measuring device 1 is provided on both main wings of an aircraft in a state of being separated from each other, and includes a pair of optical cameras 141 constituting a stereo camera and a control unit 18. The control unit 18 calculates position and attitude information on the position and attitude of each optical camera 141 on the basis of an amount of displacement of the main wings, corrects the position and direction of an image taken with each optical camera 141 on the basis of the calculated position and attitude information on each optical camera 141, and calculates distance from a photographing subject on the basis of the corrected pair of correction images.SELECTED DRAWING: Figure 1

    【課題】安価な構成で、航空機に搭載されたステレオカメラの測距精度を向上させる。【解決手段】ステレオ測距装置1、互いに離間した状態で航空機の両主翼に設けられ、ステレオカメラを構成する一対の光学カメラ141と、制御部18とを備える。制御部18は、主翼の変位量に基づいて、各光学カメラ141の位置及び姿勢に関する位置姿勢情報を算出し、算出された各光学カメラ141の位置姿勢情報に基づいて、当該各光学カメラ141により撮影された画像の位置及び向きを補正し、この補正された一対の補正画像に基づいて撮影対象との間の距離を算出する。【選択図】図1
