Stereoscopic　display　is　a　key　technology　of　virtual　reality　system,　and　it　can　enhance　the　characteristic　of　immersion.　However,　in　most　method　the　depth　of　scene　is　got　incorrectly　because　of　inaccurate　parallax.　This　paper　focuses　on　the　stereoscopic　display　technology　and　proposes　a　stereoscopic　display　method　based　on　binocular　parallax.　In　the　method,　eye　separation　is　determined　by　focal　length　and　vertical　parallax　is　eliminated.　Experimental　results　show　that　stereoscopic　effect　can　be　obtained　well　in　our　method.　©　2012　Springer-Verlag　Berlin　Heidelberg.
