To detect tip positions of all movable bodies, and to prevent two tip positions for the same movable body from being detected.SOLUTION: An information processor comprises: obtaining, in time series, first point group information based on three-dimensional point group information of a first area A1 of a movable body path RW in which a direction of a moving body is set; estimating a point group corresponding to the same movable body AM on the basis of a distance between two points, based on the first point group information; calculating an estimated tip position that is an estimate of a tip position FE of the movable body AM on the basis of the point group which is estimated to correspond to the same movable body; and determining continuity of points of the first point group information on the basis of time changes of the point group included in a continuous determination area AC set in the first area A1. When the points of two point groups which are estimated to correspond to different movable bodies AM are determined to be continuous, the two point groups are made to be point groups corresponding to the same movable body AM.SELECTED DRAWING: Figure 16

    【課題】すべての移動体の先端位置を検出しつつ、同一の移動体に対して2つの先端位置を検出することを防ぐ。【解決手段】移動体方向が定められた移動体路RWの第1の領域A1の三次元情報に基づく第1の点群情報を時系列に取得し、第1の点群情報から、2点間の距離に基づいて同一の移動体AMに対応する点群を推定し、同一の移動体に対応すると推定された点群に基づいて、移動体AMの先端位置FEの推定値である推定先端位置を算出し、第1の領域A1内に設定された連続性判定領域AC内に含まれる点群の時間的変化に基づいて、第1の点群情報の点の連続性を判定し、異なる移動体AMに対応すると推定された2つの点群の点が連続であると判定された場合、当該2つの点群は、同一の移動体AMに対応する点群であるとする。【選択図】図16
