Vision-based modeling of human behavior in production process

This paper proposes a vision-based human modeling by using both analytical property of human body performance and the concurrent gaze pattern for production process. Authors developed two systems required for 3D motion analysis: firefly capturing camera (FCC) characterized by the monocular camera with large spherical aberration of lens measures the 3D positions of point light sources attached on an object in real time without any special lighting, and passive eye camera (PEC) attached in front of the head extracts irises motion based on the facial image processing such as Hough transform for iris detection and gaze analysis. Authors demonstrated FCC and PEC are effective to construct the vision-based model of human behavior in production process.
