features. "This is very important to the control point
clouds in the project when they are combined with point
clouds from the images," Nguyen said.
"We used a drone and Nikon camera to take pictures
where a laser scanner didn't have easy access, such as
the roof, reliefs and statues," Nguyen said. "There were
36 scan stations, and when we were finished we had a
3D mesh façade with texture that was used to support
design projection mapping. This is important to the
customer since the mesh allowed them to easily and
quickly continue with the optimization."
Once VMT had captured the critical details, the
engineers developed a 3D photograph of the structure
using BIM to capture 3D details about the size and
material of the building. A 3D mesh façade of the opera
house was created from the point cloud, which VMT

The finished scan combined with digital images to produce a photorealistic view of the opera house.
