To provide a rail creepage amount measurement method capable of stably and simply measuring a rail creepage amount without being affected by a peripheral environment or the like.SOLUTION: A rail creepage amount measurement method measures a rail creepage amount from a traveling image picked up by imaging means attached to a front face of a vehicle. The measurement method extracts a pair of creepage piles provided on the right and left sides of a railway track and a mark provided on a rail in correspondence to the creepage piles from a pseudo underfloor image obtained by projectively transforming an image obtained by imaging a front side or a rear side in a traveling direction at a prescribed interval, and measures a creepage amount from a reference line obtained by connecting the creepage piles with a horizontal line of a prescribed height and the mark.SELECTED DRAWING: Figure 4
【課題】 周辺環境などに影響されず安定して簡易にレールふく進量を測定できるレールふく進量の測定方法の提供。【解決手段】 車両の前面に取り付けられた撮像手段により撮像される走行画像からレールふく進量を測定するレールふく進量の測定方法である。進行方向前方又は後方を所定間隔で撮像した画像を射影変換した疑似床下画像から、線路を挟んだ左右に設けられた一対のふく進杭及び対応してレールに設けられたマークを抽出し、ふく進杭を所定高さの水平線で結んだ基準線とマークからふく進量を測定することを特徴とする。【選択図】図4
