3D tracking aids surgical navigation
During functional endoscopic sinus surgery, instruments such as endoscopes and surgical instruments are inserted through the nose to remove nasal polyps and treat sinusitis.
Needless to say, avoiding entering the brain or injuring the eye are all paramount concerns during such surgical procedures.
To overcome this, ClaroNav (Toronto, ON, Canada; www.claronav.com) has developed a system called NaviENT that dynamically determines the position of the tip of
any surgical instrument in 3D using an optical triangulation technique. The position of
the instrument is then mapped to a corresponding location in a pre-acquired CT scan
of the patient’s head allowing the surgeon to visualize the position of the instrument in
the skull during surgery (Figure 5).
To locate the instrument’s tip, the system employs a Bumblebee XB3 three-sensor multi-baseline IEEE-1394b stereo camera from Point Grey (Richmond, BC,

prior to labelling
Food manufacturers use vision systems
to increase productivity, ensure prouduct
quality, and check package integrity.
In many cases, containers must be
correctly oriented before they can be
labelled. This was the task faced by Harris
Jones, Vice President of Engineering at
Advanced Control Solutions (ACS; Marietta, GA, USA; www.acs-ga.com) when
developing such a system for a well-known supplier of bottles of honey.

Smart cameras speed automated
Developers of automated automobile assembly
systems must ensure that, to increase productivity and lower manufacturing costs, down-time must be kept to a minimum. Not doing
so can result in increased cost that must then
be passed on to the consumer.
In the manufacture of F-150 trucks, Ford
Motor Company needed to ensure that the fuel
filler system mounted to the bed of the truck
was properly mounted. This task is complicated since four different frame lengths (
ranging from 122in to 163in) need to be accommo-

minute on a production line, ACS has

that employs two smart cameras and an
illumination system that is used to both
front and back light the bottles.
