Abstract:
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.
