3D Scanning Preserves Historical Monument for US Navy

In 1970, the Seabee Memorial began construction to build a monument in Washington, D.C. to honor the memory of those who served in Naval Construction Battalions. The famous Felex de Weldon – a former Seabee – designed the Monument of dark brown marble with bronze figures and bronze back wall.

Automated Precision volunteered their services to 3D scan the entire monument using the latest 3D scanning equipment. This will allow the CEC/Seabee Historical Foundation to render any size monument, from table-top size up to original full scale size using the 3D data modeled in DesignX. A local university will 3D print a model of the monument for the Seabee Historical Foundation.

The scanning was done by Stephen Strand, Applications Engineer for Automated Precision. Using two of API’s scanners, the API Hemiscan and the API Imager, he made a digital copy of this statute. He says, “We’re going to scan it at a pretty high resolution that way we get a pretty clean polygonal model that they will use for the 3D printing. They’ll have the ability to scale this down to a mini version, or with the density that these scanners provide you could even print a to scale model if you wanted to. The targets in the background help us combine all these positions together and creates a network of the scans as they go around. That way the scans know their positions as we walk around the statue and get the scans from the different sides.”

After programming the sectors Strand hits the start button and lets the scanner go to work. “The targets are at a decent angle. Normally you want them to be as straight as you can. I’m using one of our scanners on a low stand to get the low angles. This is good especially for the statue because it’s not shiny so we will get a good return. I was able to get it about 10 feet away which is its sweet spot. It’s only about a 4 minute scan even on ultra high resolution.
