To enable a forward/backward movement determination with a simple configuration.SOLUTION: A vehicle detector 20 detects an entrance of a vehicle into a detection area 52 and an exit of the vehicle from the detection area 52. When an entrance of a vehicle into the detection area 52 is detected by the vehicle detector 20 and when an exit of the vehicle from the detection area 52 is detected by the vehicle detector 20, an imaging apparatus 30 photographs the detection area 52. A forward/backward movement determination device 10 determines whether a vehicle having entered the detection area 52 moves forward or backward according to an approach image at a detection of an entrance of the vehicle into the detection area 52 and an exit image photographed at a detection of an exit of the vehicle from the detection area 52.SELECTED DRAWING: Figure 1

    【課題】簡便な構成によって前後進判定を行えるようにする。【解決手段】車両検知器20は、検知領域52に車両が入ったことと、検知領域52から車両が出たこととを検知する。撮像装置30は、車両検知器20によって検知領域52に車両が入ったことが検知された場合と、車両検知器20によって検知領域52から車両が出たことが検知された場合とに、検知領域52を撮像する。前後進判定装置10は、検知領域52に車両が入ったことが検知された場合に進入画像と、検知領域52から車両が出たことが検知された場合に撮像された退出画像とに基づき、検知領域52に入った車両が前進したか後進したかを判定する。【選択図】図1
