Laser Scanning Historic Wooden Homes for Preservation

Recently our Preservation Specialist, Joe Nicoli, wrote a guest post for Baltimore Heritage about the work Direct Dimensions did on the "Two Sisters" historic wooden home in the Baltimore neighborhood of Fells Point. We're delighted to share that post here as well:

Over the winter, Bryan Blundell from Dell Corporation had approached Direct Dimensions with a project to completely laser scan the Two Sisters Houses in Fell’s Point. On a sunny afternoon in March, myself and another technician with Direct Dimensions took our laser scanning equipment down to Fell’s Point and in just 30 minutes created a perfectly accurate 3D digital model of the exterior of the property.

The Two Sisters
The Two Sisters are two of just a handful of remaining wooden houses in Baltimore’s Fell’s Point. These buildings were donated to the Preservation Society by the Dashiell-Marine family. The name, The Two Sisters, recognizes the efforts of the Dashiell sisters, Mary and Eleanor, to save these and other buildings in Fell’s Point. Since that time, the Society has worked steadily to develop a plan for the saving and utilization of these significant architectural examples of early life in Fell’s Point.

3D scanning is one of the many modern technologies that can be used to help reveal some of the secrets and stories that are part of these amazing structures. The scanning can provide a baseline documentation of the building’s current state, allowing the planning team to design necessary structural supports, and to also serve as a 3D, “as-built” blue print for documenting current conditions and future preservation efforts.

What is 3D scanning?

Laser scanning is the process of collecting millions of individual measurements using laser light. Think of a range finder. A laser beam leaves the scanner on a specific orientation and the time it takes to reflect off a surface and return to the scanner establishes the distance. This happens thousands of times per second. By moving the equipment to various positions and perspectives, an entire site can be “scanned” in 3D. Once the data is merged, the resulting “point cloud” can be used to create traditional drawings, 3D models, and virtual reconstructions & walkthroughs.

So far, Direct Dimensions has only scanned the exterior on Wolfe Street, and will complete the project with funds provided to The Preservation Society by an African American Heritage Preservation Program Grant from the Maryland Historical Trust. This initial scan effort is also valuable as an archived “3D snapshot”, a record of the state of the structure in the spring of 2013.
