PROBLEM TO BE SOLVED: To accurately detect a pedestrian trying to cross a drive way in a stage before starting crossing.SOLUTION: An object pedestrian existing within a range at a predetermined distance from a drive way is detected, so as to determine whether the object pedestrian watches a crossing destination and also confirms safety with respect to a vehicle traveling on the drive way, on the basis of a visual line direction of the object pedestrian. Consequently, when the object pedestrian performs one of the actions to watch a crossing destination and to confirm safety and then performs the other action within a predetermined time, the object pedestrian is detected as a pedestrian before crossing who has an intention to cross a drive way. Thus, a pedestrian trying to cross a drive way can be accurately detected in a stage before actually starting crossing.SELECTED DRAWING: Figure 11
【課題】車道を横断しようとする歩行者を、横断し始める前の段階で精度良く検出する。【解決手段】車道から所定距離の範囲内に存在する対象歩行者を検出して、対象歩行者が横断の目的地を注視したか否か、および車道を走行する車両に対する安全確認を行ったか否かを、対象歩行者の視線方向に基づいて判断する。その結果、対象歩行者が、横断の目的地の注視、または安全確認の何れか一方の動作を行ってから、所定時間内に他方の動作を行っていた場合に、車道の横断意思を有する横断前歩行者として検出する。こうすれば、車道を横断しようとしている歩行者を、実際に横断し始める前の段階で、精度良く検出することが可能となる。【選択図】図11
