To provide a worksite management system and the like capable of further appropriately reducing contact risk between a worker and a work vehicle in a worksite.SOLUTION: A worksite management system 1 includes a ceiling camera 11 capable of acquiring image information including depth information, the ceiling camera 11 for acquiring visual line information of a driver D of a forklift, an object recognition part 12 for generating position information of the forklift F and a worker W from the image information acquired by the ceiling camera 11, a visual line camera 21 for capturing an image of the driver to acquire visual line information of the driver, a visual line recognition part 22 for recognizing a visual line direction of the driver from the visual line information acquired by the visual line camera 21, and a risk determination part 33 calculating a safety degree correlated with relative positional relation from the position information of the forklift F and the worker W and when the safety degree falls below a prescribed alarm threshold, generating alarm information. The risk determination part 33 adjusts the prescribed alarm threshold according to the visual line direction of the driver.SELECTED DRAWING: Figure 2
【課題】作業現場において作業者と作業車両との接触リスクをより適切に低減することができる作業現場管理システム等を提供すること。【解決手段】作業現場管理システム1は、深度情報を含む画像情報を取得可能な天井カメラ11と、フォークリフトFの運転者Dの視線情報を取得する天井カメラ11と、天井カメラ11により取得した画像情報からフォークリフトF及び作業者Wの位置情報を生成する物体認識部12と、運転者を撮像して運転者の視線情報を取得する視線カメラ21と、視線カメラ21により取得した視線情報から運転者の視線方向を認識する視線認識部22と、フォークリフトF及び作業者Wの位置情報から相対位置関係に相関する安全度を算出し、当該安全度が所定の警報閾値を下回ると警報情報を生成する危険判定部33と、を備え、危険判定部33は、運転者の視線方向に応じて所定の警報閾値を調整する。【選択図】図2
