- 方法 :对角膜散光小于 1.5 D的患者 113名 132眼 ,使用美国 Alcon公司的 EYEMAPTM EH- 2 90角膜地形图仪和瑞士 HAAG STREIT BERN角膜曲率计测量角膜散光。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个Bern图像和564个AR图像进行实验,分别获得了98.7%和96.6%的双眼定位成功率,表明该方法对眼睛定位过程中的视角变化、人脸表情变化和图像光照变化都具有很好的鲁棒性。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.
