MONITORING DEVICE, PROGRAM AND NOTIFICATION METHOD
To accurately represent a set threshold value in a real space (e.g., danger area) on a captured image.SOLUTION: A monitoring device for monitoring a working state of a work machine includes: an object detection unit that detects three-dimensional position information on a target object that is a monitoring target using a captured image and distance information; a work content determination unit that determines whether or not work with the work machine is safe based on the three-dimensional position information on the target object acquired by the object detection unit; a two-dimensional conversion unit that calculates two-dimensional coordinates of a set threshold value in a real space in the captured image based on the three-dimensional position information on the target object acquired by the object detection unit; and a notification unit that superimposes the threshold value in the real space on the captured image according to the two-dimensional coordinates and performs notification about the result determined by the work content determination unit.SELECTED DRAWING: Figure 3
【課題】設定している実空間上の閾値（例えば、危険エリア）を撮影画像上に正確表現する。【解決手段】作業機械の作業状態を監視する監視装置において、撮影画像および距離情報を用いて、監視のターゲットとなる対象物の三次元位置情報を検出する物体検出部と、前記物体検出部で取得した対象物の三次元位置情報に基づき、前記作業機械による作業について安全か否かを判定する作業内容判定部と、前記物体検出部で取得した対象物の三次元位置情報に基づき、設定している実空間上の閾値の前記撮影画像内の二次元座標を算出する二次元変換部と、前記二次元座標に従って前記実空間上の閾値を前記撮影画像に重畳するとともに、前記作業内容判定部で判定した結果を報知する報知部と、を備える。【選択図】図３
