Abstract
In this paper we describe a method for measuring binocular eye movement when a static random-dot stereogram (RDS) and a dynamic RDS is shown to a subject. Eye movement is measured by an image-processing technique using the image sequence of binocular fundus taken by an infra-red television fundus camera. We regarded eye movement as papillary movement. To detect the papillary position, we performed template matching (SSDA method) between a template image containing the papilla obtained from the first input image and the succeeding input images. We thereby measured the eye movements in horizontal and vertical directions. Vergent eye movement (vergence) can be observed after stereoscopic perception rather than when searching for a corresponding point.
We also tried three-dimensional display of the eye viewpoints to see where on the RDS the subject gazed.
