Comparison of Three-Dimensional Scanning Devices

There are now a variety of methods and devices for deriving 3D information, e.g. binocular camera (stereo) systems and methods of the class "shape from X". In addition, there are modern recording technologies that simultaneously measure gray scale values and distance (range cameras, TOF cameras). Many of these methods are available through low-cost sensor systems that are simple and fast to use. We propose a simple experimental setup and a processing chain in order to evaluate the quality of the data recorded by these systems. In an experiment with students we demonstrate the usability of this approach and introduce results for selected low-cost sensors
