Abstract

The embodiments of the application disclose a pupil diameter measuring method. The method comprises the following steps: acquiring a video to be detected, wherein at least one frame of image containing a pupil exists in the video to be detected; determining position information of M different feature points of a first pupil by using a deep convolutional neural network, wherein the first pupil is any one of the pupils contained in the at least one frame containing the pupil, and M is a positive integer greater than or equal to 2; and calculating the diameter of the first pupil according to theposition information. By adopting the embodiments of the application, the pupil diameter measuring method greatly reduces subjective errors of experimenters and errors caused by measuring instruments,at the same time is simple in calculation, and improves measuring efficiency and accuracy of measuring results.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a pupil diameter measuring method, device and computer-readable storage medium. Background technique [0002] The pupil is the small round hole in the center of the iris in the animal or human eye, which is the channel for light to enter the eye. The contraction of the sphincter on the iris can make the pupil narrow or dilate, that is, the diameter of the pupil will become smaller or larger. Measuring and analyzing changes in pupil diameter can help to study the way the neural circuits in the brain regulate behavior, and can also directly reflect whether you have certain diseases. Therefore, how to quickly and accurately measure pupil diameter has become an important issue. Problems that need to be solved urgently. [0003] At present, a common method of measuring pupil diameter is to take multiple photos of the pupil, place a scale on one side of the eyeball du...
