TRACK INSPECTION APPARATUS

摘要

PROBLEM TO BE SOLVED: To achieve a compact configuration and ensure prompt measurement of a track displacement. ! SOLUTION: A track inspection apparatus according to an embodiment is a track inspection apparatus to which a plurality of distance data corresponding to distances to measuring points in a plurality of portions on a measuring target rail is input, and that calculates a track displacement. Storage means stores the distance data corresponding to the measuring points in the plurality of portions at a plurality of the measurement timing as a measuring history. Measuring chord versine calculation means calculates measuring chord versines on the basis of the distance data corresponding to the same measuring timing at the measuring points in the plurality of measuring portions along an extension direction of the measuring target rail. The chord versine calculation means calculates a rail shape corresponding to a predetermined reference versine on the basis of a calculation result of the measuring chord
