| Abstract: | On the basis of the retinal light reflection,a method for real time eye location is proposed.Its feasibility is proved through the primary experiment of the judgment of the eye orientation.In this method,if there are no eyes in the cone-shaped illumination region of a point light source,no light spot also exists at the CCD and the image received by the CCD is an equably dark background.However,if there is an eye in the cone-shaped illumination region,the image captured by the CCD is a small bright light spot with dark background.The existent state,the orientation,and the location,relative to the point light source,of the eye can be derived from the position of the small bright light spot at the image captured by the CCD. |
