CREEPAGE MEASURING DEVICE, CREEPAGE MEASURING SYSTEM, AND CREEPAGE MEASURING METHOD

摘要

PROBLEM TO BE SOLVED: To improve work efficiency and measurement accuracy, etc., of creepage amount measurement by a simple configuration.;SOLUTION: A creepage measuring device 4 comprises: line sensors 11R, 11L, 12R and 12L which are loaded on a vehicle 5 that travels on rails 6R and 6L of a railroad, and photograph reference markers 2R and 2L provided integrally with a ground surface at positions separated from the rails 6R and 6L to the side and rail markers 3R and 3L provided integrally with the rails 6R and 6L during traveling; an image processing part which detects the reference markers 2R and 2L and the rail markers 3R and 3L on images photographed by the line sensors 11R, 11L, 12R and 12L; a position calculation part which calculates positions in a rail longitudinal direction of the reference markers and the rail markers from information detected in the image processing part; and a creepage amount calculation part which calculates a creepage amount of the rails 6R and 6L from the respective positions calculated in the position calculation part.;COPYRIGHT: (C)2013,JPO&INPIT
