The system results in a standard two-dimensional photo before submillimeter
comparisons are made.
He said that what sets SkillReal's system apart is not just
detecting features represented in a CAD that have an XYZ coordinate,
but how accurate the system is. " We can pinpoint the
exact location of those features with submillimeter accuracy.
And we do that in seconds. " The system is forgiving, too, able
to account for positional variations of the photographed test
object. One test of the system that Grabowski called " our John
Henry versus the machine " was conducted at a Detroit area
stamping and assembly plant. The test pitted SkillReal against
the plant's best marker auditor in a daunting challenge: evaluating
welds and other items on the entire underbody of a vehicle
involving multiple photos. The plant's operator finished in
90 minutes. " We were done in less than 10, " Grabowski said.
At the VW plant in Wolfsburg, the results were even more
dramatic. Grabowski said VW had two operators working entire
eight-hour shifts checking spot welds, while SkillReal's
software covered the same ground in 15 seconds. " They put
us through the wringer for two years, " he said. " We want to
make sure that these measurements are really sub-millimeter,
that you're really right in saying where they are. So they take
parts, measure it with their system, our system, then they put
it on a CMM. We got it commercially viable and then launched
in the States through our group NorthStar Vision, and now
we're adding more features. "
The key to efficiency and cost control for the suppliers and
manufacturers, one Skillreal adviser said, is to detect the problem
before the next part is built or sub-assembly completed.
The SkillReal software can support up to eight cameras
from the same PC running an NVIDIA graphics processing
unit. Workers can be trained to use the system in a single
eight-hour shift, Grabowski said.
SkillReal's founder and CEO is Shai Newman. Before Skillreal,
Newman founded Compedia, a company that helps publishers
transform their content into virtual 3D educational environments.
The idea for the 2D-camera inspection technology was
born when Siemens approached Compedia in its own search for
