PROBLEM TO BE SOLVED: To provide a monitoring system within an elevator hoistway that enables highly accurate detection of a swinging behavior of a long object by using a simple configuration.SOLUTION: A monitoring system within an elevator hoistway includes: a camera 22 of which imaging direction 14 relative to a long object 10 is set in a direction obliquely intersecting with a vertical axis 15 of a hoistway inner wall 23; and an image processing device 5 for analyzing a behavior of the long object 10 based on taken image data. The image processing device 5 determines a frame difference between image frames continuously supplied from the camera 22 as the image data, extracts a behavior trajectory of the long object 10 on the basis of accumulation of the frame differences and detects whether or not the behavior trajectory is deviated from a preset allowable horizontal oscillation region 15 within the image frame, so as to determine the behavior of the long object 10.

    【課題】簡単な構成で長尺物の振れ挙動を高精度に検出することができるエレベーター昇降路内の監視システムを提供する。【解決手段】長尺物10に対する撮影方向14が昇降路内壁23の垂直軸15に対して斜めに交差する方向に設定されたカメラ22と、撮影された画像データから長尺物10の挙動を解析する画像処理装置5を備え、画像処理装置5は、カメラ22から画像データとして連続的に供給される画像フレームのフレーム間差分を求め、フレーム間差分の累積で長尺物10の挙動軌跡を抽出し、その挙動軌跡が画像フレーム内において予め設定された許容横振れ領域15を逸脱したか否かを検出することにより、長尺物10の挙動を判定する。【選択図】図5
