Abstract

It is thought that indicating a skill index and training effect quantitatively is effective to improve a learning effect in endoscopic surgery training. Therefore, we propose a quantitative assessment system of endoscopic surgery training under the environment only using a camera. In our laboratory, we developed a system evaluating the surgical work flow with performance index like surgical instrument trajectory, velocity and time. In this research, we developed a system to obtain the performance index from camera images of endoscopic surgery training task, and we evaluate this system. To detect a surgical instrument, we combined background subtraction,optical flow and Hough transform.
