    • The invention relates to a method for determining distances in the anterior ocular segment, preferably of the pupils and/or the diameter of the iris, wherein the image of at least part of the eye is recorded and digitized using an imaging device and an array for illuminating the eye. On the basis of said digital image, a center of gravity analysis and the determination of the central point are carried out, especially for the position of the pupils, by conducting an intensity and threshold analysis as rough determination. Based on said rough determination, a fine detection of the position of the edges of the pupil and/or the edges of the iris is carried out. Additionally, the angle between the visual axis and the optical axis of the eye can be determined from the position of a fixed reflection to the center of the pupil and/or the center of the iris.
    • 本发明涉及一种用于确定前眼部段,优选瞳孔和/或虹膜直径的距离的方法,其中至少部分眼睛的图像使用成像装置和阵列进行记录和数字化 照亮眼睛。 在所述数字图像的基础上,通过进行强度和阈值分析作为粗略确定,进行重心分析和中心点的确定,特别是对于瞳孔的位置。 基于所述粗略确定,执行对光瞳边缘和/或虹膜边缘的位置的精细检测。 此外,可以从固定反射到瞳孔中心和/或虹膜中心的位置确定视轴和眼睛的光轴之间的角度。
