3D Scan using photographs

Follow the link to the Autodesk 123D Viewer to view the native scan

Last year we saw Jack Munro making use of the DAVID 3D Laser Scanner software to scan his sand cast. Although home-made, this scanner requires a laser and about £300 of software.

Autodesk 123D Catch is a free piece of software that allows the user to create a 3D scan [imports into Rhino as a mesh] using only a set of normal photos. It is also available as an app for the iPhone meaning that you can take the photos and upload them at the same time. All of the image processing is done on Autodesk’s servers.

The video above uses the LinceoRV augmented reality software to show a comparison between the real object and its digital mesh counterpart.

The resolution depends on the number of photos, position of photos, background, lighting conditions, etc, but the scan depicted appears to have a resolution of about ±2mm on a 120mm wide object.
