To provide a technique which enables efficient detection of an obstacle present in the vicinity of a predetermined path on which a moving body moves.SOLUTION: A system according to the present invention has two cameras 201A and 201B provided so as to be opposed to each other. Their angles of view are adjusted so that respective outer ranges of image capture should be matched with a clearance limit 220 in the middle of a vehicle. If an object is detected in both regions of middle parts of images captured by the cameras 201A and 201B, then the object is determined as an obstacle which are present in the clearance limit 220. If the obstacle is detected, each of images obtained by capturing the obstacle is recorded in association with alarm information and position information.SELECTED DRAWING: Figure 2

    【課題】動体が移動する所定の軌道の近傍に存在する障害物を効率よく検出することが可能な技術を提供する。【解決手段】互いに向い合せて設置された2つのカメラ201A、201Bを備え、それぞれ撮影できる外側の範囲が、車両の中間部分において建築限界220に一致するように画角を調整してある。これらカメラ201A、201Bにより撮影された2つの画像の両方で、その中間部分の領域(共通の領域)内に物体が検出された場合に、当該物体を建築限界220内に存在する障害物と判定する。また、障害物を検出した場合には、障害物を撮影した各画像をアラーム情報及び位置情報と共に記録する。【選択図】図2
