To calculate a roll angle of a vehicle body accurately without using many sensors and the like even when an obstacle such as a weed exists.SOLUTION: A vehicle body oscillation correction device includes a point group coordinate data acquisition unit 91 for acquiring coordinate data of a three-dimensional point group of a bed portion, a first point group extraction unit 92 for extracting coordinate data of a first predetermined region including an outer portion of a rail and a bed portion including a sleeper and ballast from the coordinate data of the three-dimensional point group, a median value calculation unit 93 for calculating a median value of a height component of the coordinate dat of the first predetermined region, a second point group extraction unit 94 for extracting only coordinate data of a second predetermined region included in a predetermined width, which is determined by the height of the rail from the median value calculated by the median value calculation unit 93 among the coordinate data of the first predetermined region, and an approximation straight line calculation unit 95 for calculating an approximation straight line of the coordinate data of the second predetermined region. The oscillation of a vehicle body included in the three-dimensional point group is corrected by using the calculated approximation straight line.SELECTED DRAWING: Figure 18

    【課題】多くのセンサ等を用いることなく、雑草等の障害物が存在した場合でも、精度よく車体のロール角を算出する。【解決手段】 道床部分の3次元点群の座標データを取得する点群座標データ取得部91と、3次元点群の座標データから、レールの外側部分、ならびに、マクラギおよびバラストを含む道床部分を含む、第1の所定領域の座標データを抽出する第1の点群抽出部92と、第1の所定領域の座標データの高さ成分の中央値を算出する中央値算出部93と、第1の所定領域の座標データのうち、中央値算出部93により算出された中央値から、レールの高さによって決まる所定の幅に含まれる第2の所定領域の座標データのみを抽出する第2の点群抽出部94と、第2の所定領域の座標データの近似直線を算出する近似直線算出部95とを備え、算出された近似直線を用いて、3次元点群が含む車体動揺が補正される。【選択図】図18
