Description
本発明に係る地図の生成方法は、複数の測域センサの計測データを用いて作成する地図の生成方法であって、前記複数の測域センサの計測点を含む前記計測データにおいて、仮想測域センサの測域範囲を複数の測定エリアに分割し、分割した前記複数の測定エリアのそれぞれにおいて、複数の前記計測点が含まれる場合に選択した1つの計測点以外の計測点を削除し、削除後に残った計測点に基づき前記地図を作成する。
図10(a)に示すように、一部の線分データ5cが障害物9と交差してしまっている。このことから、レーザ測域センサの計測点5bの中には、矛盾を生じさせるレーザ測域センサの計測点5bがいくつか存在していることがわかる。
