Method for automatically evaluating track measurement data

Abstract

A method automatically evaluates wavelet-transformed track measurement data (1) of the track geometry and/or the ballast bed with a computing device. First, a measurement series of the track measurement data (1) to be evaluated, assigned to a track section, is wavelet-transformed with a plurality of wavelets of different wavelengths. A type of thermal image, in which the wavelength above the position in a track and the wavelet transformed track measurement data are provided as thermal information, and a wavelet power density spectrum (3) are formed from these wavelet transformed track measurement data and, in addition, a signal strength diagram (4) is calculated for various wavelength ranges (D0, D1, D2, D3) The type, position, extent and size of the track defects are determined from the thermal image by determining the local position (B, C, D, F), the extent and the associated wavelength ranges (E, D0, D1, D2, D3) of predominant track defects, in particular from the contour lines of the thermal image.
