Modeling of Single Camera Location under the Natural Light in the Vedio-Oculography System

Today, most eye monitoring systems use cameras to capture eye images, which are called vedio-oculography systems (VOG). The basic elements of the VOG system are eyes, cameras and lights [1]. Especially, the location of the camera to eyes is very important. In this paper, the location of the single camera under the natural light was modeled. And the model was computed and simulated on the Matlab platform. Then, the eyes moving images were sampled by the camera In-Sight Micro 1020 from the Cognex Company to analyze the reasonable position of the camera. Test results show that the single camera should locate at the side of one eye within 40o, or it couldn’t sample clear eye moving images. This conclusion provides a reference to the further development of the actual VOG system.
