The reconstruction code is based on "Robust Pixel Classification for 3D Modeling with Structured Light". Furthermore, the calibration code follows the technique detailed in: "Simple, Accurate, and Robust Projector-Camera Calibration.".

Abstract—A Gray code and its variants are popular code-patterns for a structured light system. An n-bit Gray code is a kind of binary code whose adjacent code-strings differ only in one bit position. We introduce a specified Gray code, called an ‘antipodal Gray code.’.

light illumination source. Especially for uniform targets that do not have much salient features to match across two views, a structured light pattern is used to encode the ima es to find correspondences. There are different categories of structured light: Sequential projections, Continuous varying, Stripe Indexing, Grid ind

In this chapter we describe how to build a structured light scanner using one or more digital cameras and a single projector. While the Laser Slit 3D Scanner implemented in the previous chapter is widely used, it needs hundreds of images to build a …

These programs generate and decode structured light. Currently supports. imlist_pattern = gray. generate ((width, height)) # Projecting patterns from a projector (or display) and capture images imlist_captured = imlist_pattern img_index = gray. decode (imlist_captured, thresh=127) print …

We have investigated two different kinds of structured light: binary Gray codes, and continuous sine waves. At present, the Gray codes give us more reliable estimates of projector coordinates, due mainly to their higher insensitiv-ity to effects such as …

Structured light based on Gray code (GC) patterns is a classical technique to obtain such correspondence. Gray code patterns are a set of binary patterns coded by intensity, i.e. dark for...

The reconstruction code is based on "Robust Pixel Classification for 3D Modeling with Structured Light". Furthermore, the calibration code follows the technique detailed in: "Simple, Accurate, and Robust Projector-Camera Calibration.".

Its characteristic is that only one code of any two adjacent code words is different, and the other codes are the same, so the binary gray code is also called the unit distance code.
