PROCÉDÉ DE DÉTERMINATION D'AU MOINS UN PARAMETRE DE LA GEOMETRIE D'UNE VOIE FERRÉE, ET SYSTÈME POUR LA MISE EN OEUVRE DU PROCÉDÉ
The method of determining at least one geometric parameter of a railroad track (1) comprises the steps of: providing for a vehicle (10) carrying an inertial unit (34), a piece of equipment (28) for measuring at least one relative orientation component of at least rows of rails relative to the inertial unit and one or more odometers (26) to travel along the railroad track (1), calculating successive values of at least one absolute positioning or orientation component of the observed row of rails (2) according to the signals produced by the odometers (26), the piece of measuring equipment (28) and the inertial unit (34), constructing a function s → G (s) linking successive curved-abscissa values to concomitant values from the successive values of the absolute positioning or orientation component of the observed row of rails in the area of space, applying a bandpass or high-pass linear filter to the function s → G (s) so as to construct a filtered function s → F (s), and subsequently computing the integral value [Math 14].
