1. A method for scanning an outer surface of a three-dimensional object, the outer surface being reflective, said method comprising the following steps:
(a) projecting a light pattern on the object with a relative movement between the light pattern and the object;
(b) recording with cameras images of the light pattern reflected by the outer surface during the relative movement; and
(c) processing the recorded reflection images by identifying the outline of the light pattern and determining from the outline characteristics of the outer surface;
wherein the light pattern comprises at least one homogenously illuminated strip extending transversally to a direction of the relative movement with at least one border with a non-straight profile so as to form a non-constant width of the strip; and
wherein in step (c) the speed of the relative movement is taken into account for determining a three-dimensional definition of the outer surface.
