Structured light - Continuity vs Discontinuity

A third experiment with structured light was performed trying to scan a simple and very used scene in the video-mapping field: a group of primitive shapes.
We faced a lot of problems with this apparently simple scene and that made us think that structured light wasnt suitable for discontinuous shapes, so we built a complex but continuous geometry by wrapping the scene with a piece of cloth. The SL-applet had no trouble generating the 3d geometry.

After getting these results we asked the creator of the applet for confirmation on our early conclusion and we got a response. It was true that the experiment performed wasnt suitable for discontinuous shapes because it uses phase-shifting scanning based on the principle of propagating depth values across a surface. So if two surfaces are disconnected, it cannot determine how they are related depth-wise.
However, it wasn't true that SL is inappropriate for discontinuous shapes. Other pattern codifications and algorithms not so based on real-time can return better results for these type of scenes.
This is what we'll be working on the next weeks.
