To provide a feature point generation method, a feature point generation device and a feature point generation program with which it is possible to generate the feature points of a travel path, and a recording medium in which the feature point generation program is recorded.SOLUTION: A server generates a feature point that constitutes a candidate for a travel path, on the basis of the travel trajectory of a moving body. In this case, the server acquires the travel trajectory from an onboard device via a network. The server extracts a linear component from the travel trajectory, finds the intersection of an extension of the extracted linear component and extensions of other linear components adjacent to the linear component in the travel trajectory, and generates this intersection as a feature point when the travel trajectory passes through within a prescribed range from this intersection.SELECTED DRAWING: Figure 3

    【課題】走行路の特徴点を生成することができる特徴点生成方法、特徴点生成装置、特徴点生成プログラム及び当該特徴点生成プログラムを記録した記録媒体を提供する。【解決手段】サーバが、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。このとき、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
