DETERMINATION APPARATUS, PROGRAM, AND DETERMINATION METHOD

To provide a determination apparatus which counts the number of persons on the basis of an image captured by a camera, a program, and a determination method.SOLUTION: In a system including a determination apparatus which communicates with a plurality of cameras 2 over a network to acquire captured images, the determination apparatus includes: a captured image storage unit which stores the captured images; a detection target detection unit which detects a predetermined detection target from the captured images; a designated region acquisition unit which acquires a designated region designated by a user of the determination apparatus with respect to the captured image; a region determination unit which determines whether a ratio of an overlap region where the detection target region overlaps the designated region, with respect to the detection target region including the detection target, is higher than a predetermined overlap ratio threshold; and a detection target count unit which counts the detection targets when a determination is made that the ratio of the overlap region with respect to the detection target region is higher than the overlap ratio threshold, or does not count the detection targets when a determination is made that the ratio of the overlap region with respect to the detection target region is lower than the overlap ratio threshold.SELECTED DRAWING: Figure 8 【課題】カメラで撮像された画像を基に、人数をカウントする判定装置、プログラム及び判定方法を提供する。【解決手段】判定装置が、ネットワークを介して複数のカメラ２と通信して撮像画像を取得するシステムにおいて、判定装置は、撮像画像を格納する撮像画像格納部と、撮像画像から予め定められた検出対象を検出する検出対象検出部と、撮像画像に対して判定装置のユーザによって指定された指定領域を取得する指定領域取得部と、検出対象が含まれる領域である検出対象領域に対する、検出対象領域と指定領域とが重複する領域である重複領域の割合が、予め定められた重複割合閾値より高いか否かを判定する領域判定部と、検出対象領域に対する重複領域の割合が重複割合閾値より高いと判定した場合に検出対象をカウントし、検出対象領域に対する重複領域の割合が重複割合閾値より低いと判定した場合に、検出対象をカウントしない検出対象カウント部と、を備える。【選択図】図８
