To provide an information processing system, a monitoring device, an information processing method, and a program capable of detecting a target approaching a ship.SOLUTION: An information processing system includes: an acquisition unit that acquires a captured image captured by an imaging unit installed in a ship; an identification unit that identifies a nearest point of a target, which is image-recognized in the captured image, relative to the imaging unit; a first approach determination unit that determines whether or not the nearest point falls within a first approach area which is an area on the side of the ship in the captured image; and a first angle determination unit that determines whether or not a first angle in the captured image of the nearest point determined to fall within the first approach area remains unchanged or gets smaller. The first angle is an angle at which a direction oriented to the nearest point is oblique to an imaging axis of the imaging unit.SELECTED DRAWING: Figure 7

    【課題】船舶に接近する物標を検出することができる情報処理装置、監視装置、情報処理方法及びプログラムを提供する。【解決手段】情報処理装置は、船舶に設置された撮影部で撮影された撮影画像を取得する取得部と、撮影画像で画像認識された物標における撮影部に対する最近点を特定する特定部と、最近点が、撮影画像における船舶側の領域である第一接近領域内か否かを判定する第一接近判定部と、第一接近領域内と判定された最近点に関する撮影画像における第一角度が、同じまま又は小さくなるか否かを判定する第一角度判定部と、を備え、第一角度は、最近点を向く方向が撮影部の撮影軸に対して傾く角度である。【選択図】図7
