Design of a Monochromatic Pattern for a Robust Structured Light Coding

In this paper we present a new pattern for the robust coding of the structured light based on the spatial neighborhood scheme and by means of the M-array approach. The pattern is robust as it allows a high error rate characterized by a Hamming distance higher than 3. We tackle the design problem with the definition of a small set of symbols associated to geometrical features with simple shapes. We benefit from the stripe, as it is one of the considered primitives, to embed the local orientation of the pattern. This is helpful while performing the search for the relevant neighborhood during the decoding process. The aim of this work is to use this pattern for the 3 - D reconstruction of dynamic scenes with fast and reliable detection and decoding stages. Ongoing results are presented to assess both the capabilities of the proposed pattern and the decoding algorithm with projections onto simple 3 - D scenes.
