To generate a feature point to be a candidate of a node of a travelling road on the basis of the trace of travelling of a mobile body.SOLUTION: A server acquires a travel trace from an in-vehicle machine via a network. The server extracts a straight liner component from the travel trace, determines the intersection between the extension of the extracted straight linear component and the extension of another straight linear component adjacent to the straight linear composition in the travel trace, and generates the intersection as a feature point if the travel trace passes within a predetermined range from the intersection.SELECTED DRAWING: Figure 3
【課題】移動体の走行軌跡に基づき、走行路のノードの候補となる特徴点を生成する。【解決手段】サーバは、車載機からネットワークを介して走行軌跡を取得する。サーバは、走行軌跡から直線成分を抽出し、抽出した直線成分の延長線と、走行軌跡において直線成分に隣接する他の直線成分の延長線と、の交点を求め、その交点から所定範囲内に走行軌跡が通過していれば、その交点を特徴点として生成する。【選択図】図3
