Structured Light 3D Scanning

Step 8 Other Resources

Interactive Examples
Gray Code Decoder
This is the first 3D scanner I built, based on gray codes and intersecting projector/camera rays.

Three Phase Decoder
This is a stripped down version of a three phase decoder, implementing only the bare essentials.

Papers

Build Your Own 3D Scanner
Great overview of how 3D scanning works, with a description of the math involved.

Pattern Codification Strategies in Structured Light Systems
Amazing compilation of different approaches to structured light scanning. If you think you have better patterns than three phase scanning, compare them to the ones in this paper.

Multiview Geometry for Camera Networks
Slightly deeper introduction to the math involved in surveying a scene from multiple perspectives.

Temporal Dithering of Illumination for Fast Active Vision
Crazy approach to ultra-fast structured light that uses the dithering patterns of DLP projectors.

Researchers
Song Zhang
The researcher behind Radiohead's "House of Cards" video.

Paul Debevec
Capturing higher order material information, like subsurface scattering and polarization.

Michael Wand
Lots of work processing 3D data from structured light scanners.
