PROBLEM TO BE SOLVED: To prevent a cargo having the possibility of exceeding the weight that can be loaded at a time from being carried into a car.SOLUTION: An elevator alarm device includes: a video analysis part (21) for estimating the size and outline of a moving object entering a door opening/closing area from a landing side by generating a time-series image on the basis of video transmitted from a video photographing part (9) for photographing the door opening/closing area of a car door of an elevator to perform image processing; and a determination part (22) for determining whether the moving object corresponds to an excessive weight object on the basis of an estimation result by the video analysis part, and performing alarm notification to a user through an alarm in the case of determining that the moving body corresponds to the excessive weight object. The video analysis part divides the time-series image into blocks of a size set in advance, and estimates the size and outline of the moving object from the similarity of a motion vector acquired in each block.SELECTED DRAWING: Figure 3
【課題】かご内に一度に積載できる重量を超えるおそれのある荷物の搬入を未然に防ぐ。【解決手段】エレベータのかご戸の戸開閉領域を撮影する映像撮影部(9)から送られてくる映像を基に時系列画像を生成して画像処理を施すことで、乗場側から戸開閉領域に侵入してくる動物体の大きさおよび輪郭を推定する映像解析部(21)と、映像解析部による推定結果に基づいて、動物体が超過重量物体に当たるか否かを判定し、動物体が超過重量物体に当たると判定した場合には、警報器を介して利用者に警報報知を行う判定部(22)とを備え、映像解析部は、時系列画像をあらかじめ設定したサイズのブロックに分割し、ブロック毎に求めた動きベクトルの類似度から動物体の大きさおよび輪郭を推定する。【選択図】図3
