Paper Abstract

We propose a new projector-based augmented reality (PBAR) system which can project the image of forceps and a surgical target simultaneously for support of laparoscopic surgery. A compensation method of an error arisen from motion of a body is also proposed to improve the quality of the projection images. It is shown that the system is significant for the forceps insertion by the experiments using the dry-box.
