Abstract

On the research of traditional diopter measuring method with dioptrometer, a new approach for automatic testing of diopter is proposed. The new way took place of hand operation of dioptrometer by high resolution camera and improved mountain climbing algorithm of rapid autofocus combining rough and fine adjustment. It can improve testing efficiency and accuracy from ±0.2 diopters to ±0.008 diopters which can meet the need of accuracy and efficiency for flow line of production.
