Abstract
Laparoscopic surgery has been widely used as minimally invasive surgery. However, many accidents are reported for the difficulty of this operation. It is considered that these accidents are mainly caused by the difficulty to perceive the position of tissue at the forceps–insertion for the limited field of view in laparoscopes. In order to solve the problems, we propose a new laparoscopic surgery method by projection of laparoscopic image on the abdominal region. In this system, the distortion of projected image caused by the shape of abdominal surface and viewing position are corrected by acquiring the surface information of the projection and the position of head. We confirmed that the proposed method is significant for laparoscopic surgery by the in vitro experiment.
