To provide a remote monitoring technique capable of improving the accuracy of detection results of an object displayed on a monitoring screen while reducing communication costs.SOLUTION: An on-vehicle information processing device 20 compresses an image IMG from a camera 12 and transmits first data DT1 including the compressed image CIMG and a time stamp TS indicating acquisition time of the image IMG. The on-vehicle information processing device 20 also transmits second data DT2 including an object detection result ODR based on the image IMG and the time stamp TS indicating the acquisition time of the image IMG. A remote monitoring server 40 receives the first data DT1 and the second data DT2 and stores them in a memory. The remote monitoring server 40 extracts the compressed image CIMG and the object detection result ODR that both have the time stamp TS of the same time from the memory in chronological order, and superimposes a restored image DIMG obtained by restoring the compressed image CIMG and the object detection result ODR and displays them on a monitoring screen.SELECTED DRAWING: Figure 9

    【課題】通信コストを低減しつつ、監視画面に表示される物体の検出結果の精度を向上させることができる遠隔監視技術を提供する。【解決手段】車載情報処理装置20は、カメラ12の画像IMGを圧縮し、圧縮画像CIMGと画像IMGの取得時刻を示すタイムスタンプTSとを含む第1データDT1を送信する。また、車載情報処理装置20は、画像IMGに基づく物体検出結果ODRと画像IMGの取得時刻を示すタイムスタンプTSとを含む第2データDT2を送信する。遠隔監視サーバ40は、第1データDT1と第2データDT2とを受信してそれぞれメモリに格納する。遠隔監視サーバ40は、タイムスタンプTSが同時刻である圧縮画像CIMGと物体検出結果ODRとをメモリから時系列に抽出し、圧縮画像CIMGを復元した復元画像DIMGと物体検出結果ODRとを重畳して監視画面に表示する。【選択図】図9
