摘要 为改善摄影验光仪的性能,缩短检测时间和提高检测准确度,描述了一种新型双裂隙偏心摄影验光仪的验光原理,介绍了双裂隙偏心摄影验光仪的特点、关键技术,提出了通过图像处理得到眼睛屈光度的方法。 In order to improve the performance of the photorefraction device, shorten the detection time and improve the accuracy of measuring, the theory of a new kind of double-cranny eccentric photorefraction device is described. Some features and key point of technology are emphatically pointed out. A method is put forward to determine the ocular diopter by image processing.
