1. Introduction
Noncontact optical surface digitization techniques have evolved substantially during the last decades [1]. Structured light techniques, based upon the projection of 2D patterns [2], form an interesting subset. One of the more advanced instances combines a time series of binary or color coded patterns with a limited number of shifted 2D sine waves [3]. The former yield robust but low resolution 3D information. The latter, through a technique often referred to as profilometry or phase shifting [4], are used to boost the local resolution. We follow a similar strategy, but with patterns that self-adapt to the scene.
