摘要

Stereo vision-based triangulation systems are commonly used to reconstruct the three-dimensional surface shape of objects. In order to increase accuracy, they typically contain a projector which projects a sequence of patterns onto the object's surface. However, in spite of a considerable demand to measure dynamic processes, such systems are often limited to static objects. In order to enhance their speed, apart from fast cameras and projection systems, it is useful to use pattern sequences as short as possible. In this contribution, we experimentally compare two different illumination approaches, aperiodic sinusoidal fringes and phase-shifted sinusoidal fringes, with regard to the achievable point cloud completeness and accuracy depending on the pattern parameters and sequence length.
