Abstract:
The present disclosure provides a method of remotely measuring a size of a pupil, including: acquiring an image of a to-be-measured person by using a detection device; acquiring an image of a pupil of the to-be-measured person from the image of the to-be-measured person; measuring a distance between the to-be-measured person and the detection device by using the detection device; and calculating an actual size of the pupil of the to-be-measured person based on the measured distance and the image of the pupil of the to-be-measured person. The present disclosure further provides an apparatus for remotely measuring a size of a pupil, an electronic device, and a non-transitory computer-readable medium.
