To provide a soil discharge state monitoring device which determines whether a soil discharge state is a soil discharge end state, in which earth and sand in a vessel are perfectly dropped onto a ground surface, or not.SOLUTION: The soil discharge monitoring device comprises: a storage part which successively stores rear images photographed by a rear camera of a dump truck which comprises a vessel for loading loads and the rear camera for photographing the rear of a vehicle body; a vessel standing determination part which sets a vessel standing determination area on an upper side partial region in current and past rear images, and calculates a time change of a pixel value in the vessel standing determination area by use of the past rear image and the current rear image, thereby determining standing of the vessel; and a soil discharge end determination part which sets a soil discharge end determination area on a rectangular region which has an upper side configured from a bottom side of the vessel standing determination area set in the current and past rear images, and has a bottom side configured from an own vehicle structure area which is calculated from shape information concerning the vehicle body, and calculates a time change of a pixel value in the soil discharge end determination area by use of the past rear image and the current rear image, thereby determining soil discharge end.SELECTED DRAWING: Figure 3

    【課題】ベッセル内の土砂が地面に落ちきった放土終了状態か否かを判定する放土状態監視装置を提供する。【解決手段】積荷を積載するベッセルと、車体の後方を撮影する後方カメラとを備えたダンプトラックの後方カメラが撮影した後方映像を逐次記録する記憶部と、現在及び過去の後方映像内の上側の一部領域に、ベッセル起立判定領域を設定し、過去の後方映像と現在の後方映像を用いて、ベッセル起立判定領域内の画素値の時間変化を演算することでベッセルの起立を判定するベッセル起立判定部と、現在および過去の後方映像内に設定されたベッセル起立判定領域の底辺を上辺とし、車体の形状情報から算出される自車構造物領域を底辺とする矩形領域に、放土終了判定領域を設定し、過去の後方映像と現在の後方映像を用いて、放土終了判定領域内の画素値の時間変化を算出することで放土終了を判定する放土終了判定部とを備える。【選択図】 図3
