Method, and relative apparatus, for checking tyres in a tyre production line comprising alternately illuminating, with a first and second grazing light radiation, a surface portion of the tyre and respectively acquiring a first and second two- dimensional digital image of said illuminated surface portion, wherein for each point (P, P') of the surface portion, the respective overall light power of the first and second light radiation incident at the point respectively comes from two half-spaces that are opposite with respect to an optical plane (107) passing through the perpendicular to the surface at the point; and comparing the first and second image in order to obtain information on an altimetric profile of the surface portion. 用于检查轮胎生产线中的轮胎的方法及相关设备，包括：用第和第二掠射光辐射交替照射轮胎的表面部分，并且分别获得所照射的表面部分的第和第二二维数字图像，其中对于表面部分的每个点(P，P')，入射在该点处的第和第二光辐射的相应的总体光功率分别来自相对于光学平面(107)相对的两个半空间，所述光学平面经过该点处的表面的垂线；和比较第和第二图像，以便获得有关表面部分的测高轮廓的信息。
