Description

本開示に係る画像解析システムは、前記撮影範囲において、前記昇降設備の動作によって外観上の変化がある変化領域を選択する領域選択部と、前記画像取得部が取得する撮影画像のうち、予め設定された判定期間の間に撮影された撮影画像において、撮影画像の前記判定期間を通じた変化量が予め設定された第２閾値より小さい領域が前記変化領域の中にある場合に、当該領域の異常を判定する異常判定部と、を備え、前記判定期間は、前記昇降設備の利用者による前記昇降設備の利用間隔より長い時間に設定される。
本開示に係る画像解析システムは、前記撮影範囲において、前記昇降設備の動作によって外観上の変化がある変化領域を選択する領域選択部と、前記画像取得部が取得する撮影画像のうち、予め設定された判定期間の間に撮影された撮影画像において、撮影画像の前記判定期間を通じた変化量が予め設定された第２閾値より小さい領域が前記変化領域の中にある場合に、当該領域の異常を判定する異常判定部と、を備え、前記昇降設備は、エレベーターであり、前記変化領域は、前記エレベーターの表示装置の領域である。 The image analysis system according to the present disclosure includes an area selection unit that selects a change area in which the appearance changes due to the operation of the lifting equipment in the imaging range, and a preset area selected from among the captured images acquired by the image acquisition unit. If there is an area within the change area in which the amount of change in the image during the judgment period is smaller than a preset second threshold in the image taken during the judgment period, an abnormality is detected in the area. an abnormality determination unit that determines the above, and the determination period is set to a time longer than the interval between uses of the elevator equipment by a user of the elevator equipment .
