A method of determining the position and the orientation of at least one interface comprises illuminating the interface that is determined with at least one non-polarized diffuse light source point, using an image-forming device to acquire an image enabling polarization information determined about the reflection(s) of the source point on the interface to be determined, and in the image, locating any reflection of the light source point as reflected by the interface. For each located reflection, the light ray reaching the image-forming device together with at least its degree of polarization as its polarization parameter is calculated. The light ray as reflected on the interface that to be determined is calculated. Using the light ray reflected on the interface, its polarization parameter, and the known position of the source point, the position and the orientation of the surface element is deduced.
