PROBLEM TO BE SOLVED: To provide a measured value error correction method for a track inspecting and measuring device for correcting the error of a measured value under the influence of mechanical variation of the track inspecting and measuring device hardly causing correction errors by working errors including input errors and other operating errors because inspecting and measuring work itself is simple besides dispensing with manual inspection and measurement for the correction of inspection and measurement performed by the track inspecting and measuring device, which results in reducing time and labor for manual inspection and measurement, the number of tools to be carried into a track and influence caused by the difference between manual inspection and measurement errors and manual inspection and measurement accuracy to improve correction accuracy. SOLUTION: In this measured value error correction method for the track inspecting and measuring device, the track inspecting and measuring device is installed in a normal state to a railway track to carry out traveling measurement of a fixed section, and the track inspecting and measuring device is installed in a laterally reversed state to carry out traveling measurement of the same fixed section. Both measured values are compared to correct the error of the measured values under the influence of mechanical variation of the track inspecting and measuring device. COPYRIGHT: (C)2006,JPO&NCIPI
