The invention relates to a method for characterizing, from a volume image, a fibrous structure having a three-dimensional weaving between a plurality of warp yarns extending along a first direction and a plurality of weft yarns extending along a second direction perpendicular to the first one, the method comprising: a first processing of the volume image by filtering along a third direction perpendicular to the first and second directions so as to attenuate the periodic patterns along the third direction, obtaining a two-dimensional image corresponding to an intermediate plane along the third direction of the filtered volume image, a second processing of the two-dimensional image by filtering along the first or second direction so as to attenuate the periodic patterns, obtaining a one-dimensional profile representing the positions of warp or weft columns and corresponding to an intermediate line along the first or second direction.
