Abstract

The invention is applicable to the technical field of image processing, and provides a pupil distance measurement method and device, terminal equipment and a storage medium, and the method comprises the steps: obtaining an image including two eyes; extracting pupil center image coordinates of the two eyes according to the images; and calculating the pupil distance between the two eyes according tothe pupil center image coordinates. According to the pupil distance measurement method and device, the terminal equipment and the storage medium, pupil center image coordinates of two eyes in the two-eye image are extracted by using a digital image processing technology; compared with a traditional method of directly measuring the pupil distance through a calibrated scale, the pupil distance measurement precision is greatly improved, the pupil distance measurement precision can be improved to the pixel level, namely, the micron order of magnitude, and the problem that the measurement precision is low in existing double-eye pupil distance measurement is solved.

Description

technical field [0001] The present application belongs to the technical field of image processing, and in particular relates to a pupil distance measurement method, device, terminal equipment and storage medium. Background technique [0002] With the current changes in people's lifestyles and working methods, the intensity of eye use is increasing. Opticians are no longer just for seeing objects clearly, but need to be worn comfortably and use eyes for a long time. In the process of glasses processing, it is necessary to process glasses according to the interpupillary distance and lens center of the glasses prescription. If there is an error between the optical center point of the glasses and the pupil center point, the visual axis will deviate from the center of the lens, causing the "prism effect". Wearing glasses can only greatly increase the burden on the adjustment function of the eyes in order to see the target clearly. Over time, vision fatigue, dizziness, headache, ...
