To provide an overhead line measurement apparatus capable of reducing time and labor required from actual measurement to storage of data and preventing an occurrence of erroneous writing and incorrect input.SOLUTION: An overhead line measurement apparatus comprises: a laser device 2 attached to a carriage 20 running on a rail 30 constituting a track, which irradiates a head surface 30a of the rail with a laser beam 201 directing vertically upward in a shape of a fan opened vertically to the extending direction of the rail; an image pickup unit 3 mounted at a position away from the laser device of the carriage so that reflected light 202 of the laser beam reflected by an overhead line 41 of the predetermined height is picked up at a predetermined reference position within a picked-up image; a movement distance measuring unit for measuring a movement distance of the carriage; a storage unit; and a computation processing unit for storing the calculated height and horizontal deviation in the storage unit in association with the movement distance after calculating a height and a horizontal deviation of a position at which the reflected light is reflected on the basis of a deviation from a reference position of a position at which reflected light of the laser light is imaged in the pick-up image captured by the image pick-up unit.SELECTED DRAWING: Figure 3

    【課題】実際の測定からデータの保存までの時間や手間を減らすことができ、また、誤記や誤入力の発生を防止する架線測定装置を提供する。【解決手段】線路を構成するレール30上を走行する台車20に取り付けられ、レールの頭面30aに対して垂直方向上向きで、レールの延伸方向と垂直に扇を開く形の扇状に、レーザ光201を照射するレーザ装置2と、レーザ光が所定の高さの架線41で反射した反射光202が撮像画像内の所定の基準位置で撮像されるように台車のレーザ装置から離れた位置に取り付けられた撮像部3と、台車の移動距離を測定する移動距離測定部と、記憶部と、撮像部が撮像した撮像画像内でレーザ光の反射光が撮像された位置の基準位置からの偏差に基づき反射光が反射した位置の高さと水平偏位を算出し、移動距離測定部が測定した移動距離に対応づけて、算出した高さと水平偏位を記憶部に記憶する演算処理部とを備える架線測定装置である。【選択図】図3
