Zusammenfassung:To provide a highly accurate and convenient monitoring device with a simple and inexpensive configuration.SOLUTION: One or more markers 200 are attached to a monitored object. A monitoring device 100 includes: a camera 110; a trained marker recognition unit 120 that detects the coordinates in the captured image of the marker 200 included in the captured image from the captured image by the camera 110 and the distance between the marker 200 and the camera 110 in the real space; a marker position calculation unit 130 that calculates the position of the marker 200 in the physical space based on the coordinates and the distance detected by the marker recognition unit 120; and a warning processing unit 140 that outputs a warning based on the position of the marker in the physical space calculated by the marker position calculation unit 130 and area information of a monitoring area 10.SELECTED DRAWING: Figure 2 【課題】簡便且つ安価な構成で精度且つ利便性の高い監視装置を提供する。【解決手段】監視対象物に1つ以上のマーカー200を付設する。監視装置100は、カメラ110と、カメラ110による撮像画像から当該撮像画像に含まれるマーカー200の撮像画像内における座標及び現実空間におけるマーカー200とカメラ110との間の距離を検出する学習済みのマーカー認識部120と、マーカー認識部120により検出された座標及び距離に基づきマーカー200の現実空間における位置を算出するマーカー位置算出部130と、マーカー位置算出部130により算出されたマーカーの現実空間における位置と監視領域10の領域情報とに基づき警告を出力する警告処理部140とを備える。【選択図】図2
