Course Outline
The
course is divided into two sessions. In the first session we introduce
3D scanning, present the underlying mathematics of 3D triangulation,
and describe their application to a simple "swept-plane" scanner.
Specifically, we implement Bouguet's desktop
3D scanner
using only a webcam, a halogen lamp, and a stick. In the second session
we describe how to build a structured light scanner using a calibrated
projector-camera pair. We conclude by presenting a minimal
post-processing pipeline to convert the point clouds produced by the
various scanners to watertight meshes.First Section: 8:30 AM - 10:15 AM
