3D machine vision opens new possibilities in robot guidance. To pick up randomly placed objects from a container box or pallet is impossible with 2D vision because the objects will float together in the 2D-image making the differentiation between the objects to be picked impossible.

3D vision with SICK IVP Ranger solves this in an elegant way with images containing a 3D map of the objects on the pallet. The objects on top can easily be segmented with a simple threshold operation since the intensity value corresponds to the height position.
