A method is described for detecting defects on tyres in a tyre production process. The method comprises providing a tyre, comprises acquiring (202) a three-dimensional image of a surface portion of the tyre, comprises generating (204), as a function of the acquired image, a plurality of values indicating the measure of a height profile (S_pa) of the surface portion of the tyre, comprises calculating (205), as a function of the plurality of values of the measure of the height profile and according to a consensus interpolation, a plurality of values indicating an estimation of a reference height profile (<Spar>) of the surface portion of the tyre, comprises calculating (206), as a function of the plurality of values of the measure of the height profile and of the estimation of the reference height profile, a height profile of possible defects (S_papd) in the surface portion of the tyre, and comprises comparing (207, 208) values of the height profile of possible defects with respect to a threshold value (S_th) in order to detect possible defects in the surface portion of the tyre. |
