Description

technical field [0001] The invention relates to iris recognition technology, in particular to an iris recognition device. Background technique [0002] The appearance of the human eye consists of three parts: sclera, iris, and pupil. The sclera is the white part of the periphery of the eyeball, accounting for about 30% of the total area; the center of the eye is the pupil, accounting for about 5%; the iris is located between the sclera and the pupil, and contains the most abundant texture information, accounting for 65%. In appearance, it is composed of many glandular fossa, folds, pigmented spots, etc. It is one of the most unique structures in the human body. The formation of the iris is determined by genetics, and human gene expression determines the shape, physiology, color and general appearance of the iris. When a person develops to about eight months, the iris basically develops to a sufficient size and enters a relatively stable period. Except for rare abnormal co...
