PROBLEM TO BE SOLVED: To provide an abnormality monitoring system, abnormality monitoring method, computer program, and abnormality monitoring device capable of suppressing erroneous detection to occur in response to a road state when an abnormality is detected in an imaging apparatus and a radio communication device by comparing the number of detected vehicles.SOLUTION: An abnormality monitoring system includes an imaging section, a communication section, a road observation section, the first count section, the second count section, a road state determination section, and an abnormality detection section. The imaging section acquires the image of a road. The communication section performs communication with on-vehicle units. The road observation section acquires state information indicating a road state. The first count section counts the first vehicle number by detecting vehicles from the image. The second count section counts the second vehicle number on the basis of communication with the on-vehicle units. The road state determination section acquires road information indicating a congestion degree of a road on the basis of the state information. The abnormality detection section acquires the proportion of vehicles mounting the on-vehicle units and detects an abnormality in the imaging section or the communication section on the basis of the first vehicle number, the second vehicle number, the road information, and the proportion of the vehicles.SELECTED DRAWING: Figure 2

    【課題】検出された車両数の比較によって撮像装置及び無線通信装置の異常を検出する場合において、道路の状況により生じる誤検出を抑制することができる異常監視システム、異常監視方法、コンピュータプログラム及び異常監視装置を提供することである。【解決手段】実施形態の異常監視システムは、撮像部、通信部、道路観測部、第1計数部、第2計数部、道路状況判定部及び異常検出部を持つ。撮像部は道路の画像を取得する。通信部は車載器と通信する。道路観測部は道路状況を示す状況情報を取得する。第1計数部は画像から車両を検出し第1車両数を計数する。第2計数部は車載器との通信に基づいて第2車両数を計数する。道路状況判定部は状況情報に基づいて道路の混み具合を示す道路情報を取得する。異常検出部は車載器を搭載する車両の割合を取得し、第1車両数、第2車両数、道路情報及び車両の割合に基づいて撮像部又は通信部の異常を検出する。【選択図】図2
