To provide a moving body detection system that can limit a scope of moving bodies to be detected to detect a moving body accurately.SOLUTION: In a body detection system 1 according to the present invention, a recognition device 10 comprises: moving body detection means 11 for detecting the presence of a vehicle C when a light source with constant illuminance penetrates into a closed domain S in an imaging area R1; closed domain passage detection means 12 for detecting passing through of the vehicle C from change in the average illuminance; filtering means 13 for excluding a moving body as a moving body not passing through the closed domain S when the average illuminance does not change in the closed domain S; and means 14 for determining movement along neighboring closed domains for determining whether the vehicle C that has passed through the closed domain S has passed through a neighboring closed domain T neighboring it at its upper side within a prescribed time.SELECTED DRAWING: Figure 2
【課題】検知対象の移動体を限定して、高精度で移動体を検知することができる移動体検知システムを提供する。【解決手段】本発明の移動体検知システム1において、認識装置10は、一定照度の光源が撮像領域R1内の閉領域Sに侵入したとき車両Cの存在を検知する移動体検知手段11と、平均照度の変化から車両Cの閉領域Sの通過を検知する閉領域通過検知手段12と、閉領域Sにおける平均照度が変化しない場合に閉領域Sを通過しない移動体として検知対象から除外するフィルタリング手段13と、閉領域Sを通過した車両Cがその上側に隣接する隣接閉領域Tを指定時間内に通過したかを判定する隣接閉領域間移動判定手段14を備えている。【選択図】図2
