Short summary
The analysis of constructional steel structures (such as car shells for rail vehicles) in terms of (i) dimensional checking according to DIN 25043-2:2012 and (ii) completeness checking represents a challenge. The use of 3D scanners is combined with using an adapted algorithm; the respective 3D model as the target state is superimposed with difference images. These difference images show possible dimensional deviations as well as possible missing parts or, at the least, suspect points.
