Utilizing 3D Scanning for Historic Preservation

At Direct Dimensions we are using some new technologies that we believe are a perfect fit for preservation applications not only because they are fast and highly accurate, but because they are also non-contact methods of acquiring massive amounts of data that can be used for documentation, restoration and preservation.

The Druid Hill Arch is a perfect example of how our team was able to collect highly accurate data of a large monument in less than a day.

Step 1) A team of Direct Dimensions engineers and team members from John Milner Associates arrive on-site at approximately 8 AM to begin set up. Within thirty minutes they are ready to start scanning the arch.

Step 2) Using the portable Surphaser HSX Spherical Scanner the team was able to take over 20 scans in the next few hours. The Surphaser is perfect for architectural preservation projects because it can be taken anywhere (it can be carried on a plane) and is made to quickly and accurately scan mid-large range objects such as planes, vehicles and buildings.

Step 3) Our team finished scanning/data collection and was back in our office, aligning all the data by close of business the same day.

Step 4) Initial deliverables include plan views and elevations, but the data can also be used for physical reproductions, animations, renderings, virtual environments or anything else you can think of.

Stay tuned! We're still working on the Druid Hill Arch and are excited to show some of the 3D visualizations we've been working on.

Do you, or anyone reading this, happen to know when the actual restoration work is going to begin? Your posts about the scanning of the archway are now 4 years apparently did this work in the summer of 2009. A few years ago was the 150 anniversary of the park, and at one of the many exhibits and talks going on, it was said that the work was to begin "soon". In the three years since, the only thing that I've seen happen was the installation of some hurricane fencing which closed off part of the archway, presumably so the archway's crumbling ceiling doesn't injure a pedestrian.
I realize your firm isn't doing the restoration part of the work, but if someone is privy to what is holding things up, or knows the schedule of when work was supposed to have begun, it would be nice for this neighbor to know! Thanks in advance, and it's great work you're doing with the historic scanning - Chris
