PROBLEM TO BE SOLVED: To provide a method and a device for measuring track deviation of a concrete track that cannot be easily affected by irregularities on the surface of the concrete track, cope with a sharp positional change in a track, such as a level difference, and measure a vertical deviation, a pass deviation, or the like in a running state of an inspection vehicle. SOLUTION: In measurement of a track deviation of a concrete track in a running condition of the inspection vehicle, the measuring device performs median filtering for setting a width for removing irregularities on the surface of the concrete to measurement values of measurement signals of digital values obtained from a distance detector, and calculates a track deviation quantity of a monorail based on the measurement values obtained by the median filtering.
