Universal decoding method for periodic wave patterns in structured light illumination

For structured light decoding, we propose a universal decoding method for periodic wave patterns based on traditional phase measuring profilometry(PMP). By applying PMP phase computation algorithm in such periodic wave patterns, as triangular, sawtooth and square wave patterns, we could achieved accurate final phases by temporally unwrapping phases of the patterns with sufficiently high frequency. Experiments using a white wall as the testing surface and reconstructing a white plaster statue demonstrate that, the proposed method is valid as it can achieve comparable accuracy.
