However, the indirect method of observing and manipulating in laparoscopy impairs the surgeon’s eye-hand coordination, which makes it difficult to carry out a laparoscopic operation successfully. Then we initiate the optical see-through technique in order to find solutions for these difficulties of laparoscopy. Methods: The floating display mechanism of optical see-through technique is proposed and deeply researched to overcome the mislocation of camera picture and the misorientation of instrument movements. The line-of-sight of endoscope is transformed and coincides with the surgeon’s natural line-of-sight. The pictures of endoscope are projected onto the semi-transparent mirror between the surgeon’s eyes and the abdomen, and the pre-operative information from X-ray, ultrasound or MRI images are also mapped onto the endoscope camera pictures, which gives the surgeon the visual sense of seeing through the skin. An experimental optical see-through system is constructed. Results: Extensive experiments are conducted on phantoms to verify the accuracy and stability of the constructed system. Experimental results show that the optical
