| Abstract | Active 3D imaging systems use artificial illumination in order to capture and record digital representations of objects. The use of artificial illumination allows the acquisition of dense and accurate range images of textureless objects that are difficult to acquire using passive vision systems. An active 3D imaging system can be based on different measurement principles that include time-of-flight, triangulation, and interferometry. Here, an in-depth presentation of triangulation-based 3D imaging is provided, including both scanning laser and structured light projection systems, with a focus on industrial applications. The characterization of triangulation is discussed using both an error-propagation framework and experimental protocols. |
