Abstract
Computer-based simulators have been developed to enhance training experiences in laparoscopic surgical skills training. Most simulators can evaluate a trainee’s performance objectively. However, only few simulators can provide active guidance features such as audio and visual guidance. In this paper, an object state estimation and tracking method is presented to support visual and force guidance for computer-assisted surgical trainer (CAST) using image processing schemes in real-time fashion given a specific object transfer task. The experimental results show that the proposed tracking method reaches 100 frame per seconds and estimates an object state effectively for the standard laparoscopy peg transfer task.
