Abstract

PURPOSE: To improve the precision of a track curve by removing a ghost waveform from the track curve by performing required arithmetic as to input measurement data of a track passage deviation or track height deviation obtained in the three- point measuring method.
CONSTITUTION: From three-point measurement system 15 provided to a detecting- measuring vehicle, track deviation data ΔY are supplied to A/D converter 16. On the other hand, sampling pulse generator 17 generates sampling pulse SP in proportion to a distance by using distance pulse DP from the detecting-measuring vehicle, A/D converter 16 samples and digitizes data ΔY of every constant distance to obtain deviation value [ΔY], and original-curve arithmetic circuit 18 obtains an original curve. Of the original curve, the curve part or wave component long in gradient part is eliminated by digital filter 19. To eliminate a measurement error when the vehicle body changes in direction greatly as the detecting-measuring vehicle moves, initial-value setting circuit 22 resets an initial value. Thus, the precision of the track curve can be improved.
