Abstract

A találmány tárgya eljárás távolságok meghatározására elülsőszemszegmensen, előnyösen pupilla- és/vagy íriszátmérőmeghatározására, amelynek során képfelvevő egység és szemmegvilágítására szolgáló elrendezés segítségével a szem legalább egyrészének képét rögzítik és digitalizálják, és a digitális kép alapjándurva meghatározásként intenzitás-küszöbérték elemzésen keresztülkülönösen a pupilla helyzetének vonatkozásában súlypontelemzést ésközéppont-meghatározást hajtanak végre és a durvameghatározás alapjána pupillaperemek és/vagy íriszperemek helyzetének finomdetektálásáthajtják végre, és járulékosan egy visszfénynek a pupillaközéppontjához és/vagy az írisz középpontjához képesti helyzetealapján a szem látástengelye és optikai tengelye közötti szögethatározhatják meg.
