SIGN BODY INFORMATION DEVICE AND SIGN BODY INFORMATION PRESENTATION SYSTEM
To eliminate dispersion of determination by a confirmation person by recognizing a part requiring repair of a road sign body on a map.SOLUTION: A server 60 comprises: an acquisition unit (communication unit 62) that acquires, from a vehicle-mounted device 10, position information of a point at which an image including a road sign body is captured and distance information indicating a detection distance of the road sign body detected from the image; a map data accumulation unit 65 that accumulates map data including at least a place; a determination unit (control unit 61) that determines an abnormal state of the road sign body based on a comparison result of the detection distance and a threshold; and an output unit (communication unit 62) that outputs result information obtained by superimposing a determination result of the determination unit on the map data.SELECTED DRAWING: Figure 8
【課題】道路標示体の補修が必要な箇所を地図上で認識できるようにし、確認者による判断のばらつきをなくす。【解決手段】サーバ６０は、車載器１０から、道路標示体を含む画像が撮影された地点の位置情報と、画像から検出された道路標示体の検出距離を示す距離情報とを取得する取得部（通信部６２）と、少なくとも地点を含む地図データを蓄積する地図データ蓄積部６５と、検出距離と閾値との比較結果に基づいて、道路標示体の異常状態を判定する判定部（制御部６１）と、地図データ上に判定部の判定結果を重畳した結果情報を出力する出力部（通信部６２）と、を備える。【選択図】図８
