Automated Multi-sensor Inspection of 3D Objects

Considering modern manufacturing processes, there is an increasing demand for flexible, fast and precise inspection systems. An inspection can for instance consist of the verification of the geometrical form of the object or the detection of undesired surface features, like scratches, dents or bumps. All in all, an appropriate inspection system must comply with two main requirements: On the one hand, any part of the three-dimensional surface of the object must be examined with respect to a lot of different specifications, which often requires different, adapted measurement techniques and sensors. On the other hand, the inspection has to be done on large areas whereas the critical dimension of any feature may be much smaller.
