1. Method for the contactless, fast, and accurate measurement of the spatial extent of an object (1), e.g. a three-dimensional body, in which at least one laser (2) is being converted by means of an associated telecentric lens/Fresnel lens (3) or a parabolic mirror in each an orthogonal beam curtain (4) to the support surface of the object (1), so that a reflected laser light line (5) impinges on both sides of the object (1) to be measured, partially on the object and partially on the support surface, whereby each laser light line (5) which impinges the support surface is detected with at least one optical camera (6), which is arranged in a stationary position to the associated laser (2) outside the beam curtain (4) and a telecentric lens/Fresnel lens (7) or a parabolic mirror which detect the beams from this laser light line (5), the said beams being parallel to each other and comprise an acute angle with the beam curtain (4).
