摘要： The present disclosure provides a method of determining a distance and a height, including: measuring, a first distance, a second distance and a third distance from the security inspection device to the tested person as well as measuring a first height, a second height and a third height of the tested person; determining, a relationship between the first distance and a minimum distance threshold as well as a maximum distance threshold, a relationship between the second distance and the minimum distance threshold as well as the maximum distance threshold, and a relationship between the third distance and the minimum distance threshold as well as the maximum distance threshold; determining, a final distance from the security inspection device to the tested person and a final height of the tested person; and performing a pixel conversion and a size conversion on the pupil image of the tested person.

摘要： 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.
