Laser-pointing endoscope system for natural 3D interface between robotic equipments and surgeons

Precise measurements of reference points would be mandatory of robotic equipments would be introduced in operation rooms. We develop a real-time laser-pointing endoscope using an optical galvano scanner and a 955fps high-speed camera. This system provides the scanned 3D image of the liver under the endoscopic surgery and a touch screen interface so that surgeons can intuitively indicate points of interest with precise 3D position. Some results of in-vivo experiments on a liver of pig are shown to verify the effectiveness of the proposed.
