ClearEdge3D's Verity software identify discrepancies in as-built structures. BY TIM O'CONNOR

E

very builder knows that what's
shown on a blueprint or in a 3-D
rendering never exactly matches
up with the end result. Something as small as a misaligned bolt could
alter the placement of a support beam in
a way that impacts how the structure fits
together and its overall strength. Understanding those imperfections and having
an accurate picture of the real-world
building requires a way to map an as-built
model of the structure
Laser scanners are the first step in building a precise 3-D model of an environment.
A high-end terrestrial laser scanner digitally captures the shape of physical objects
in a 270-degree view, capturing up to one
millions points of data each second. Those
points are then merged into a point cloud

made of billions of dots to create a precise
3-D model of the existing conditions, in
this case a building. Multiple scans can be
conducted to create a complete point cloud
map of the structure.

"...The biggest mistakes are
where no one is looking."

- Kelly Cone, vice president of product management

However, the resulting point cloud
doesn't contain what each grouping of
points represents. It doesn't know the
differences among a structural beam, water
pipe or window. Contractors must manually
identify those structures within the model,
a laborious and time-consuming process
that reduces the usability and value of reality capture for construction or operation.
The founders of ClearEdge3D realized
that if they could train a computer to recognize building components in a point cloud
the way a human does then they could
displace a lot of the manual labor and time
needed to produce an as-built model. The
company began developing algorithms to
solve that problem in 2006 and it launched
its first software product, EdgeWise, in 2011.
EdgeWise uses object and pattern recog-
