The paper "Pattern Codification Strategies in Structured Light Systems" by Joaquim Salvi, Jordi Pagès, and Joan Battle provides an overview of coded structured light techniques used for surface reconstruction. Structured light systems project coded patterns onto a scene and capture the illuminated scene from multiple viewpoints to recover 3D information. The authors present a comprehensive classification of coding strategies, including time-multiplexing, neighborhood codification, and direct codification. They discuss various techniques within each category, such as binary codes, n-ary codes, combination of Gray code and phase shifting, and hybrid methods. The paper also reviews experimental results from several techniques, highlighting their accuracy and applicability. Additionally, it discusses the advantages and constraints of different patterns and provides guidelines for selecting the most suitable technique based on specific application requirements.The paper "Pattern Codification Strategies in Structured Light Systems" by Joaquim Salvi, Jordi Pagès, and Joan Battle provides an overview of coded structured light techniques used for surface reconstruction.
