RAILROAD CROSSTIE PROCESSING-PURPOSE DATA PREPARATION SYSTEM
PROBLEM TO BE SOLVED: To provide a crosstie processing-purpose preparation system that can prepare data necessary upon interchanging railroad crossties as a measurement vehicle moves on a rail.SOLUTION: A data conversion unit 33 is configured to prepare first, second and third three-dimensional point group data obtained by using scanner units set at points opposing a front face left side, front surface right side, and front surface center of a railroad crosstie, of a direction orthogonal to an advancement direction of a measurement vehicle 2. A data preparation unit 35 is configured to extract point group data on a prescribed width of a plane face along a wall of a front face of the railroad crosstie respectively from the first, second and third three-dimensional point group data. Further, the data preparation unit 35 is configured to calculate a thickness of a left side of the railroad crosstie on the basis of first two-dimensional point group data; calculate a thickness of a right side of the crosstie on the basis of second two-dimensional point group data; and calculate a length of an upper side of the railroad crosstie on the basis of third two-dimensional point group data.SELECTED DRAWING: Figure 3
【課題】計測車両がレールの上を移動しながら、枕木を交換する際に必要となるデータを作成できる枕木加工用データ作成システムを提供する。【解決手段】データ変換部３３は、計測車両２の進行方向と直交する方向のうち、枕木の正面左側、正面右側および正面中央に対向する地点に設置されたスキャナ部を用いて得られた第１、第２および第３の三次元点群データを作成する。データ作成部３５は、前記第１、第２および第３の三次元点群データから、枕木の正面の壁に沿った平面の所定幅の点群データをそれぞれ抽出して、第１、第２および第３の二次元点群データを作成する。更にデータ作成部３５は、第１の二次元点群データに基づいて枕木の左辺の厚みを算出し、第２の二次元点群データに基づいて枕木の右辺の厚みを算出し、第３の二次元点群データに基づいて枕木の上辺の長さを算出する。【選択図】図３
