Detection of the Center of Eyes’ Position Based on Grating Projection Method

In traditional grating auto-stereoscopic displays,the head movement would lead to the crosstalk of 3D images. There is a way to minimize the crosstalk from utilizing eyes’ position to rearrang the RGB sub-pixels.In this paper, a method to detect the center of eyes which is based on black and white binary grating projection is proposed. After projecting periodic grating composed by black and white stripes from projector,the CCD intakes deformed stripes,using the offset which is compared the deformed fringe with the reference to restore facial contours. Recover the morphology conveniently from encoding every deformed stripe with an unique code. Experimental results show that this method requires less image,has strong anti-interference abilitity.It is easy to get the position of eyes’center after getting the face contour,so this method could be applied as a new way in the nose and face recognition and tracking fields.
