The use of visual sensors for industrial and research applications have had a strong impulse in the latest
years. The major motivations behind this scenario are the progressive cost reduction of
high-performance vision systems as well as the capability to extract
multiple information from a workspace in a non-invasive manner. Actually,
possible industrial applications are, e.g., assembly of mechanical parts, edge
following, object grasping, whereas possible non-industrial applications are,
e.g., automotive guidance, spatial and underwater robotics. Efficient multiple visual
tracking of 3D objects in unstructured environments, visual servoing of industrial robots and object grasping are the focus of research.
