PROBLEM TO BE SOLVED: To provide a railroad wayside structure measurement support device capable of measuring railroad wayside structures without traveling on rails.SOLUTION: A railroad wayside structure measurement support device 100 includes a recording section 190, an operation section 170, a data display section 180, a reference vector determination section 120, and a distance calculation section 140. The operation section 170 can dispose reference rails at an arbitrary position and direction of three-dimensional coordinates. The data display section 180 can display marks representing measurement point groups and the reference rails disposed in the three-dimensional coordinates from an arbitrary view point. The reference vector determination section 120 calculates a central vector representing the direction of the rails and a planar normal vector in which heads of the pair of reference rails are present, from the position and direction of the reference rails. The distance calculation section 140 calculates the height and separation of a designated distance calculation point with respect to the reference rails using the central vector and the normal vector.
【課題】鉄道沿線の構造物を、レール上を走行することなく測定できる鉄道沿線構造物測定支援装置を提供する。【解決手段】鉄道沿線構造物測定支援装置100は、記録部190、操作部170、データ表示部180、基準ベクトル決定部120、距離算出部140を備える。操作部170は、基準レールを3次元座標の任意の位置と方向に配置できる。データ表示部180は、3次元座標内に配置された測定点群と基準レールを示すマークを、任意の視点で表示できる。基準ベクトル決定部120は、基準レールの位置と方向から、レールの方向を示す中心ベクトルと1組の基準レールの頭部が存在する平面の法線ベクトルとを求める。距離算出部140は、中心ベクトルと法線ベクトルを用いて、指定された距離算出点の基準レールに対する高さと離れを求める。【選択図】図2
