Elegant solution to
challenging requirements
With complex inspections of this
kind, the challenge is two-fold: users
need to coordinate and combine the
results from multiple cameras that
are needed to perform the task; and
data processing for the system as a
whole often forms a bottleneck for
the required rapid test sequence.
Conventional multi-camera systems
use “dumb” cameras attached to a
controller. These dumb cameras lack
their own processing power – so
they share the processing power of
the controller. As more cameras are
added to the system performance
of the system reduces, and limits
multi-camera systems to simple

cameras for what are known as
multi view inspections. Only in this
way is it possible to inspect objects
from different viewpoints following
a defined, pre-specified procedure,
i.e. the individual cameras are
connected interdependently. For
example: After camera 1 has
detected and identified an object
(bottle, tube, glass etc.), the
system’s other multi-view cameras
2, 3 and 4 can check for particular
specified critical features according
to the system configuration.
Multi-view inspections are becoming
more and more important in a
variety of industries: in the food
industry, in beverage filling, in the
automotive sector and in general
mechanical engineering situations,
