3D body scanning with "Flying Triangulation"

In (S. Ettl et al., Proc. DGaO 2009: A13) we introduced the new measurement principle "Flying Triangulation" for the comfortable and motion-robust acquisition of 3D data. The sensor, based on single shot light sectioning, is freely guided around the object, while a series of sparse 3D views is generated. These views are aligned to each other "on the fly". The measurement progress is displayed in real time and a dense 3D model is generated within a few seconds. This year we present a handheld 3D sensor based on Flying Triangulation, for large-scale objects such as human bodies or furniture, or even entire rooms. The motion-robust sensor consists of two cameras and two perpendicular laser line pattern projection systems. It can freely be moved around the object without requiring any external tracking system. The sensor has high potential in cultural heritage and medical applications such as surgery or as a motion tracking system in radiation therapy. We will show several applications and measurement results.
