Virtual Shadow Drawing System Using Augmented Reality for Laparoscopic Surgery

Laparoscopic surgery holds great promise in medicine but remains challenging for surgeons because it is difficult to perceive depth while suturing. In addition binocular parallax, such as three-dimensional vision, shadow essential perception. This paper presents an augmented reality system that draws virtual shadows aid On the visual display, generates mimic actual by estimating positions using image processing. The distance and angle between forceps tip surface were estimated evaluate accuracy of system. To validate usefulness this surgical applications, novices performed suturing tasks with without error delay sufficiently small, generated similar shadows. Furthermore, decreased significantly when was used. shadow-drawing developed study may help during laparoscopic surgery.
