To set a determination threshold value in accordance with features of a determination area even when a plurality of determination areas that cover a monitoring object in video captured by an imaging device are provided.SOLUTION: A wide area monitoring device comprises: setting means for providing a plurality of determination areas in which delay of monitoring objects is to be determined for video captured by an imaging device; detection means for detecting monitoring objects in the plurality of determination areas on the basis of the video captured by the imaging device; counting means for counting the number of monitoring objects passing through each of the plurality of determination areas in a certain time; occupancy extraction means for extracting an occupancy of each monitoring object for the plurality of determination areas; critical occupancy extraction means for extracting the occupancy of each monitoring object as a critical occupancy of each determination area when the monitoring object is at a maximum value for each of the plurality of determination areas; and determination means for determining the delay of each monitoring object in the plurality of determination areas on the basis of the critical occupancy of the plurality of determination areas.SELECTED DRAWING: Figure 6

    【課題】撮像装置で撮影した映像に監視対象物にかかる複数の判定領域が設けられた場合にも、判定領域の特徴に応じた判定閾値を設定する。【解決手段】撮像装置で撮影した映像に対して、監視対象物の滞りの判定を行う複数の判定領域を設ける設定手段と、撮像装置で撮影した映像に基づき、前記複数の判定領域内の監視対象物を検出する検出手段と、一定時間における前記複数の判定領域をそれぞれ通過する前記監視対象物の数を計数する計数手段と、前記複数の判定領域に対するそれぞれの前記監視対象物の占有率を抽出する占有率抽出手段と、前記複数の判定領域それぞれについて前記監視対象物が最大値となる時の前記監視対象物の占有率を当該判定領域の臨界占有率として抽出する臨界占有率抽出手段と、前記複数の判定領域の臨界占有率に基づき、前記複数の判定領域における前記監視対象物の滞りをそれぞれ判定する判定手段と、を備える。【選択図】図6
