Abstract

Advances in computer vision technology and virtual reality technology have been achieved through improvements in camera performance and computability. Cost-effective simulation systems for laparoscopic surgery are proposed by combining such technologies. In this study, we propose a novel 3D instrument tracking technique using a single camera to obtain the 3D positions, roll angle, and grasper angle of a laparoscopic instrument. The 3D tracking of the instrument requires that all of the markers are collinear and that the actual distances between markers are known The results of our study show that the minimum uncertainty in the position was 0.237 mm and the maximum uncertainty in the position was 1.476 mm.
