To more accurately determine whether or not there is a person in a dangerous area in a person recognition device for a garbage truck.SOLUTION: A person recognition device for a garbage truck includes: a camera 7 in which a center of an image pickup lens 70 is located at a leading edge 4a of a dust input port 4 or behind it in a plan view, and an optical axis A of the image pickup lens 70 is directed toward the dust input port 4; an image processing unit 8 that determines whether or not a person H is in front of a trailing edge 4b of the dust input port 4 in an image taken by the camera 7; and an emergency stop device that stops an operation of a dust loading device when it is determined that the person H is in a dangerous area near the dust input port 4. The emergency stop device stops an operation of the dust loading device when it is determined by the image processing unit 8 that the person H is in a dangerous area while it is determined that a rotating plate of the dust loading device is operating in a dangerous angle range, based on a signal from a switch.SELECTED DRAWING: Figure 5
【課題】塵芥収集車の人物認識装置において、危険なエリアに人物が居るか否かの判定をより正確に行えるようにする。【解決手段】撮像レンズ70の中心が平面視で塵芥投入口4の前縁部4aまたはそれよりも後方に位置するとともに当該撮像レンズ70の光軸Aが塵芥投入口4に向けられたカメラ7と、カメラ7によって撮影された画像において塵芥投入口4の後縁部4bよりも前方に人物Hが居るか否か判定する画像処理ユニット8と、塵芥投入口4近傍の危険なエリアに人物Hが居ると判定された場合に塵芥積込装置の作動を停止する緊急停止装置とを備える。緊急停止装置は、画像処理ユニット8によって危険なエリアに人物Hが居ると判定され、かつ、スイッチからの信号に基づいて、塵芥積込装置の回転板が危険な角度範囲にて作動していると判定した場合に、塵芥積込装置の作動を停止させる。【選択図】図5
