Summary:PROBLEM TO BE SOLVED: To provide a monitoring system for detecting an object possessed by a person to be detected from a terahertz image without stopping the person to be detected at a predetermined position.SOLUTION: A monitoring system includes a first image acquisition unit (a terahertz image acquisition unit 101), a second image acquisition unit (a visualized image acquisition unit 102), a person detection unit 103, an object detection unit 105, an object classification unit 106, and a display unit 108. The first image acquisition unit receives a terahertz wave emitted from a person passing through a predetermined position and acquires a first image in which the predetermined position is imaged based on the reception result of the terahertz wave. The second image acquisition unit receives light reflected at the predetermined position and acquires a second image in which the predetermined position is imaged based on the light reception result of the light. The person detection unit detects a person from the second image. The object detection unit detects an object possessed by the person from a first position corresponding to the detected person in the first image.SELECTED DRAWING: Figure 1 【課題】所定位置において検出対象人物を止めることなく、テラヘルツ画像から、検出対象人物が所持する物体を検出する監視システムを提供する。【解決手段】監視システムは、第１画像取得部（テラヘルツ画像取得部１０１）と、第２画像取得部（可視化画像取得部１０２）と、人物検出部１０３と、物体検出部１０５と、物体分類部１０６と、表示部１０８と、を備える。第１画像取得部は、所定位置を通過する人物から放出されるテラヘルツ波を受信し、当該テラヘルツ波の受信結果に基づいて、所定位置を画像化した第１画像を取得する。第２画像取得部は、所定位置で反射した光を受光し、当該光の受光結果に基づいて、所定位置を画像化した第２画像を取得する。人物検出部は、第２画像から、人物を検出する。物体検出部は、第１画像における当該検出した人物に対応する第１位置から、人物が所持する物体を検出する。【選択図】図１
