Res Gestae Divi Augusti, Ara Pacis, Rome, Italy

3D Model of the Res Gestae Divi Augusti on the wall of the Ara Pacis museum, Rome, Italy. Created from 13 images taken on an iPhone 5s. While the wall is completely flat, the model has a slight curve due to uncorrected lens distortion in the camera.

Res Gestae Divi Augusti (The Deeds of the Divine Augustus) is the funerary inscription of the first Roman emperor, Augustus, giving a first-person record of his life and accomplishments. The Res Gestae is especially significant because it gives an insight into the image Augustus portrayed to the Roman people. Various inscriptions of the Res Gestae have been found scattered across the former Roman Empire. The inscription itself is a monument to the establishment of the Julio-Claudian dynasty that was to follow Augustus. Wikipedia

This is incredible. The video below, from the Fraunhofer Institute for Computer Graphics Research (Fraunhofer IGD), showcases what the latest 3D digitisation technology can achieve. Their CultLab3D modular scanning system can take a cultural artefact and produce a high resolution 3D model in just ten minutes. Amazingly, this system carries out all the post processing, image colour correction and texture creation automatically; all the curator has to do is place the object on the conveyor belt at the start, and remove it at the end.

Through automation, 3D digitisation can now be carried out at scales previously unheard of, bringing with it a reduction in cost. By bringing down the cost of 3D digitisation, Fraunhofer IGD claim to have made it financially viable for institutions to digitise whole collections.

From VisualSFM to MeshLab

VirtualSFM point cloud before cleaning.So you’ve created a dense point cloud with vertex colour in VisualSFM, (or any other software), and now you want to convert this into a textured 3D model. How do you do that? With MeshLab, creating textured meshes from point clouds is a straightforward process. This quick tutorial will show you how.

There are three steps in the workflow:

  1. Edit the high resolution VisualSFM colour point cloud
  2. Create a 3D model from the high resolution point cloud
  3. Transfer the colour attributes from the point cloud to the mesh
