| 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. An active 3D imaging system can be based on different measurement principles that include time-of-flight, triangulation, and interferometry. The different time-of-flight technologies allow the development of a plethora of systems that can operate at a range of a few meters to many kilometers. In this chapter, we focus on time-of-flight technologies that operate from a few meters to a few hundred meters. The characterization of these systems is discussed and experimental results are presented using systems related to construction, engineering, and the automobile industry. |
