To provide a driving environment monitoring device, a driving environment monitoring system, and a driving environment monitoring program, that obtain images containing abnormal situations within an appropriate time range.SOLUTION: A server device 10A includes: a data collection section 30 that collects vehicle behavior data; a scene extraction section 31 that extracts a driving scene according to the behavior of the vehicle and a scene feature amount for each driving scene, from the collected vehicle behavior data; an abnormality detection section 32 that calculates a degree of abnormality indicating a degree of deviation of the scene feature amount for each extracted driving scene with respect to a driving model, and detects the driving scene including an abnormality point using the calculated degree of abnormality; a section determination section 33 that extracts the driving scene that fulfills a predetermined condition from the detected driving scene and a plurality of driving scenes continuous to the driving scene, and determines a time range determined by the total duration of the extracted driving scenes as an abnormal behavior section; a video requesting section 34 that requests the video according to the determined abnormal behavior section from the vehicle; and a display controlling section 36 that performs control to display the video obtained from the vehicle according to the request.SELECTED DRAWING: Figure 3
【課題】適切な時間範囲で異常事態が収められた映像を得る。【解決手段】サーバ装置10Aは、車両挙動データを収集するデータ収集部30と、収集された車両挙動データから、車両の挙動に応じた運転シーン及び運転シーン毎のシーン特徴量を抽出するシーン抽出部31と、運転モデルに対する、抽出された運転シーン毎のシーン特徴量の乖離度合いを表す異常度を算出し、算出した異常度を用いて、異常地点を含む運転シーンを検出する異常検出部32と、検出された運転シーン及び運転シーンに連続する複数の運転シーンの中から、予め定められた条件を満たす運転シーンを抽出し、抽出した運転シーンの継続時間の合計により定まる時間範囲を、異常挙動区間として決定する区間決定部33と、車両に対して、決定された異常挙動区間に応じた映像を要求する映像要求部34と、要求に応じて、車両から取得した映像を表示する制御を行う表示制御部36と、を備える。【選択図】図3
