PROBLEM TO BE SOLVED: To separate adjacent different objects and detect the object when objects are detected by performing grouping processing with respect to radar measurement information.SOLUTION: An object detection device 10 comprises: a capture area extraction part 11 for extracting one or more unit areas in which measurement information generated by a radar device 20 using one or more reflection waves from one or more objects, from plural unit areas, as one or more capture areas for capturing one or more objects; a preliminary grouping part 12 for forming a preliminary group containing one capture area existing in a prescribed area from the capture area; a feature amount acquisition part 13 for calculating a feature amount indicating relation between the preliminary group and one or more capture areas in the preliminary group based on the measurement information; a determination part 15 for determining kinds of one or more objects to which one or more capture areas in the preliminary group belong, for every capture area based on the feature amount; and an object determination part 16 for performing grouping to the capture areas for every kind of the object for detecting one or more objects.SELECTED DRAWING: Figure 1 【課題】レーダ測定情報に対しグルーピング処理を施すことによって物体を検出する場合、隣接する異なる物体を分離して検出すること。【解決手段】物体検出装置１０は、複数の単位領域の中から、レーダ装置２０が１つ以上の物体からの１つ以上の反射波を用いて生成した測定情報が閾値を超える１つ以上の単位領域を、１つ以上の物体を捕捉する１つ以上の捕捉領域として抽出する捕捉領域抽出部１１と、捕捉領域から所定範囲内に存在する１つの捕捉領域を含む予備グループを形成する予備グルーピング部１２と、測定情報に基づいて予備グループと当該予備グループ内の１つ以上の捕捉領域との関連を示す特徴量を算出する特徴量取得部１３と、特徴量に基づいて予備グループ内の１つ以上の捕捉領域が属する１つ以上の物体の種別を捕捉領域毎に判別する判別部１５と、捕捉領域を物体の種別毎にグルーピングして１つ以上の物体を検出する物体確定部１６と、を有する。【選択図】図１
