Abstract

Structured light methods are triangulation-based methods for acquiring range data. Light sections are projected and encoded by sequences of light intensities. The association of sequences of intensities to light sections, called 'coding,' plays a major role in range data acquisition by structured light methods. The coding has an influence on the resolution, the speed and the robustness of the measurement. In this paper we present binary codes, used in structured light methods. Ideally we want codes, which combine high resolution with a short measuring time. Such a code would be called 'efficient.' We present important properties of binary codes for structured light and rules for the construction of efficient codes. By applying these rules of construction we have found new, highly efficient, binary codes. The efficiency of the new codes is compared to the efficiency of well-known codes and the maximum efficiency that can be achieved.
