Time-of-Flight Endoscopy: Fusion of color and 3D information

Date: June 5, 2009 Time: 11.15 AM Location: MI 03.13.010

Abstract: This talk describes the accomplishment of the Time-of-Flight (ToF?) measurement principle via endoscope optics. The applicability of the approach is verified by in-vitro experiments. Off-the-shelf ToF? camera sensors enable the per-pixel; on-chip; real-time; marker-less acquisition of distance information. The transfer of the emerging ToF? measurement technique to endoscope optics is the basis for a new generation of ToF? rigid or flexible 3-D endoscopes. No modification of the endoscope optic itself is necessary as only an enhancement of illumination unit and image sensors is necessary. Currently; a depth measurement precision of 0.89 mm at 20 fps with 3072 3-D points is achieved. Finally; preliminary results on the fusion of simultaneously acquired endoscopic color and 3D information are described.
