Abstract

L'invention concerne un procédé de de calcul du temps de trajet d'une onde ultrasonore (2b) dans un milieu, ayant les étapes successives : - fermeture (E3) pour détecter l'enveloppe (S2) de l'onde ultrasonore (2b) de réponse, - segmentation (E4) de ligne de partage des eaux, pour déterminer une position temporelle (T1, T2, T3) de chaque écho correspondant à chaque maximum local (M1, M2, M3), - positionnement (E5) d'une fenêtre temporelle (W1, W2, W3) autour de chaque position (T1, T2, T3), - fermeture (E6) dans chaque fenêtre (W1, W2, W3) pour chaque écho, - segmentation (E7) de ligne de partage des eaux dans chaque fenêtre (W1, W2, W3), pour y détecter le pic (P1) le plus tôt, pour chaque écho, - calcul d'un coefficient (E8) d'inter-corrélation des premiers pics (P1), - calcul (E9) du temps de trajet (TTM) des ondes ultrasonores dans le milieu (P) à partir des pics (P1) correspondant à un coefficient supérieur ou égal à une valeur.
