Coded structured light is a computer vision technique which aims to reconstruct objects. This kind of technique belongs to the group of active triangulation methods. The setup usually consists of a LCD projector and a camera. The LCD device projects a pattern or a set of patterns so that finding correspondences between the projected and the viewed images becomes easier. The coding strategy used to generate the patterns determines the performance of the system in terms of resolution (number of encoded points) and accuracy. This paper presents a classification of the existing techniques as well as a new coding strategy which aims to optimise classic one-shot patterns based on De Bruijn codification.
