Technology Gives A 3D Snapshot In Time For Kerikeri’s Stone Store

stone building

A Kerikeri
engineering firm has used state of the art 3D laser scanning
technology to create a high-precision model of New
Zealand’s oldest stone building – and the results are
amazing.

Vision Consulting Engineers recently used a
series of scans both inside and outside the Stone Store to
capture a moment in time in the building’s 185-year
history. The engineers used technology that projects, then
records, hundreds of millions of points of light to create a
virtual picture of the historic landmark.

The hundreds
of millions of data points both inside and outside the Stone
Store were then drawn together by Engineering Technician
Callum Smith using advanced computer programming to produce
stunning views of the interior and exterior of the building
from a multitude of angles.

“The results are
accurate to within a couple of millimetres and literally
give us a snapshot in time of this extraordinary
building,” says Vision Consulting Senior Civil Engineer
Ben Perry.

“This technology isn’t new – but the
equipment and software we have used is cutting edge. We were
really impressed with the results it gave
us.”

Heritage New Zealand Pouhere Taonga staff were
also impressed – not just with the imaging, but also the
potential heritage applications that the scanning and
software technology could provide.

“These might
range from extremely accurate recording of collection items
within a historic building, through to detailed assessment
of conservation and maintenance of heritage structures, and
even the possibility of providing virtual tour
experiences,” says Heritage New Zealand Pouhere Taonga
Northland Regional Archaeologist Dr James
Robinson.

“What Ben and his team have done is given
us a taste of what this technology can potentially do. We
can now reflect further on how it might best be
used.”

The scanning project was undertaken partly to
showcase the potential of the technology, but also because
– in Ben’s words – “it was a cool thing to
do.”

“This technology is often used in
construction projects for things like quantity surveying. We
wanted to put it through its paces in a completely different
context and for a very different purpose. The Stone Store
was the perfect test for us,” he says.

“It’s
also given us greater understanding of how this technology
can be used with a wide range of different applications for
our clients.”

The digital information will be given
to Heritage New Zealand Pouhere Taonga free of
charge.

“We’re very grateful to Ben and his team
for their generous contribution of time and expertise,”
says James.

“I know it will give us a lot of food
for thought about potential heritage applications. The
process is non-invasive, affordable and incredibly accurate
– which all adds up to a lot of potential for people
working in the heritage
field.”
