PROBLEM TO BE SOLVED: To provide a technique for detecting the location of the vehicle with high accuracy.SOLUTION: Image generation means (S105-S110) generates an image-capture image vertically looking down a road around the vehicle on the basis of image-capture information from an image-capturing device attached to the vehicle. Sign recognition means (S115) recognizes, in the image-capture image, the shape of a road sign drawn on the road. Map data acquisition means (S120) acquires map data representing a map image in which the shape of the road sign is included. Location correction means (S125-S130) compares the shape of the road sign recognized by the sign recognition means with the shape of the road sign that is included in the map image and is present around the vehicle, and corrects an absolute location of the vehicle.

    【課題】自車位置を精度よく検出するための技術を提供する。【解決手段】画像生成手段(S105〜S110)は、自車両に取り付けられた撮像装置からの撮像情報に基づいて、自車両周辺の道路を鉛直方向に見下ろした撮像画像を生成する。標示認識手段(S115)は、撮像画像において、道路に描画された道路標示の形状を認識する。地図データ取得手段(S120)は、道路標示の形状が含まれた地図画像を表す地図データを取得する。位置補正手段(S125〜S130)は、標示認識手段により認識された道路標示の形状と、地図画像に含まれる道路標示であって自車両周辺に存在する道路標示の形状と、を対比して自車両の絶対位置を補正する。【選択図】図5
