To provide a road surface image management system that is able to highly-accurately extract new and old images of an identical point, and easily perform comparisons and the like.SOLUTION: According to an embodiment, a road surface image management system is installed on a road traveling body, inputs road surface images in which an identical route is repeatedly photographed and collected at a prescribed distance or a time interval by a camera having a function obtaining photographing information including positions and time information at photographing timings and each of the photographing information, and records them into a first recording section, selects new and old images of the identical point from the recorded road surface images for performing mapping processing, records a mapping processing result into a second recording section, extracts and outputs an original image representing the old image of any point from the first recording section and a target image representing the new image to be mapped with the original image based on the recorded mapping processing result.SELECTED DRAWING: Figure 1
【課題】同一地点の新旧画像を高精度に抽出して比較等を容易に行うことのできる路面画像管理システムを提供する。【解決手段】実施形態によれば、路面画像管理システムは、道路走行体に搭載され、撮影時の位置及び時刻情報を含む撮影情報を取得する機能を有するカメラで、同一のルートを所定の距離または時間間隔で繰り返し撮影して収集される路面画像とそれぞれの撮影情報を入力して第1の記録部に記録し、記録された路面画像から同一地点の新旧画像を選択して紐付け処理を行い、紐付け処理結果を第2記録部に記録し、記録された紐付け処理結果に基づいて前記第1記憶部から任意の地点の旧画像である元画像と当該元画像に紐付けされる新画像であるターゲット画像を抽出して出力する。【選択図】図1
