To provide a road surface evaluation system that can grasp how a road surface changes over the passage of time.SOLUTION: A road surface evaluation system comprises: a storage unit that stores imaging data acquired from an imaging unit in association with position data; and a data processing unit that reads the imaging data and the position data from the storage unit. The data processing unit includes: a parameter calculation unit that calculates a travel vector indicating a travel direction of an inspection vehicle at the time when the imaging data is captured from an amount of change in the position data at prescribed time intervals; and a data retrieval unit that refers to the position data associated with the plurality of imaging data stored in the storage unit and the travel vector, determines a similarity of each, and reads comparison source imaging data and comparison destination imaging data in which the road surface of the same location is imaged from the storage unit.SELECTED DRAWING: Figure 1

    【課題】時間の経過とともに路面が経年変化する様子を把握することができる路面評価システムを提供する。【解決手段】路面評価システムは、撮像部から取得した撮像データを位置データと関連付けて記憶する記憶部と、撮像データおよび位置データを、記憶部から読み込むデータ処理部と、を備え、データ処理部は、位置データの所定時間毎の変化量から、撮像データが撮像された時点での検査車両の進行方向を示す進行ベクトルを算出するパラメータ算出部と、記憶部に記憶された複数の撮像データと関連付けられた位置データ、および進行ベクトルを参照し、それぞれの類似性を判断し、同一箇所の路面が撮像された比較元撮像データおよび比較先撮像データを、記憶部から読み込むデータ検索部と、を備えている。【選択図】図1
