- 它發(fā)韌于1905年瑞士Bern專(zhuān)利局,初創(chuàng )于1924年印度達卡大學(xué)與柏林大學(xué),發(fā)展于1970年代Bell、MIT、stanford,實(shí)現于1995年NIST。It originated at Bern Bureau of Patent, started at Daka University and BerlinUniversity, developed at Bell Lab. , MIT, Stanford, and completed at NIST.
- 方法 :對角膜散光小于 1.5 D的患者 113名 132眼 ,使用美國 Alcon公司的 EYEMAPTM EH- 2 90角膜地形圖儀和瑞士 HAAG STREIT BERN角膜曲率計測量角膜散光。Methods:We tested corneal astigmatism of 113 patients (132 eyes)by using topographer (EYEMAP TM EH 290,ALCON,USA)and keratometer(HAAG STREIT BERN,SWISS),all the patients?corneal astigmatism was less than 1 5D. Results:we found that both the highest and the smallest curvature measured by the topographer were significantly higher than that by the keratometer (P<0 05).
- 利用150個(gè)Bern圖像和564個(gè)AR圖像進(jìn)行實(shí)驗，分別獲得了98.7%和96.6%的雙眼定位成功率，表明該方法對眼睛定位過(guò)程中的視角變化、人臉表情變化和圖像光照變化都具有很好的魯棒性。Experimental results on a set of 150 Bern images and another set of 564 AR images show that correct eye locating rates of 98.7%25 and 96.6%25 have been achieved, respectively.
