Method and system for detecting the three-dimensional shape of an object

摘要

The invention relates to a method for detecting the three-dimensional shape of an object (2) during which an object (2) provided with photogrammetrically evaluable marks (4) is placed on a surface (5) at a predetermined location. This surface is provided with additional photogrammetrically evaluable marks (6) that are arranged in a predetermined manner with regard to one another. The surface extends in such a manner that the additional marks (6) are arranged around the contact surface of the object located on the surface. A number of images of the object (2) are taken from different views so that, in addition to the object (2), the surface (5) is also at least partially depicted. The three-dimensional shape of the object is determined from the images with the aid of the markers (4) of the object and of the markers (6) of the surface (5) by using a photogrammetric method. The inventive method enables slim objects to be digitized with a high degree of precision whereby eliminating the need for a scale that was placed in the images according to the prior art. The invention also relates to a system for implementing the method.
