Abstract
As medical technologies become higher and more complex, and an environment of surgical procedure inside operation room (OR) also become more complex. To understand problems on surgical staff workflow in OR, optimize the surgical procedures, and establish more safe environment of treatment in OR, an analysis of surgical workflow and trajectory analysis in OR is quite important to understand and analyze the surgical procedure. Then we have developed system for 3D trajectory measurement of surgical staff in OR using two cameras and video analysis using image subtraction and stereo matching. In this study, we proposed 3D trajectory measurement system of surgical staff in OR using four cameras with occlusion handling. Experimental result shows our system has potential to avoid occlusion of objects and a problem on occlusion due to multi-person identification.
