Embodiment 1

[0038] This embodiment proposes an iris positioning system, such as figure 1As shown, it includes: an iris module, a control module, a drive module and a height level detection module, wherein the height level detection module is used to detect the height range of the height of the object to be measured, and feeds back to the control module; the control The module is used to determine the height level according to the height range of the height of the object to be measured, and sends a control signal to the drive module; the drive module is used to receive the control signal sent by the control module to drive the iris module to move to the vertical view of the iris module The field angle θ covers the height level corresponding to the height of the object to be measured.

[0039] Wherein, the iris module includes a lens, and the driving module drives the lens of the iris module to move, so that the vertical viewing angle θ of the iris module covers the height level correspondi...

Embodiment 2

[0042] The present embodiment proposes a kind of iris positioning system, can also make following improvement on the basis of embodiment 1: described iris module, control module, drive module and height grade detection module are installed in the first position, such as figure 2 As shown, the horizontal distance between the first position and the object to be measured is L, and the value range of L is: 30cm-60cm; in specific applications, L can be 30cm, 60cm, 31cm, 55cm, 35cm, 40cm, 50cm, 45cm and other values. Wherein, the first position corresponds to different positions according to the application scenarios of the iris positioning system; for example, when the iris positioning system is applied to a lock or an access control system, the first position is on the door, when When the iris positioning system is applied to a lockbox, the first position is on the lockbox.

Embodiment 3

[0044] This embodiment proposes an iris positioning system, and the following improvements can be made on the basis of the technical solution of Embodiment 1 or 2: the height level detection module includes N laser sensors, and the N laser sensors emitted by the N laser sensors The laser divides the height range of the object to be measured into N+1 height levels, N≥1, and N is an integer. In specific applications, N can be: 1, 2, 3, 4, 5, 6 and other values; the corresponding height level is: 2, 3, 4, 5, 6, 7 and other values. like figure 2 As shown, N is 2, which are respectively recorded as: the first laser sensor and the second laser sensor from bottom to top; there are 3 height levels, which are respectively recorded as: the first height level, the second height level, and the third height from bottom to top grade. The laser beams emitted by the two laser sensors form an included angle with each other, and the included angle is less than or equal to the vertical viewin...

Abstract

The invention provides an iris positioning method, an iris positioning system and an iris lock, which belong to the technical field of iris positioning. The iris positioning system comprise an iris module, a control module, a driving module and a height grade detection module, wherein the height grade detection module is used for detecting a height range of the height of a to-be-detected object and feeding back the height range to the control module; the control module is used for determining a height grade according to the height range of the height of the to-be-measured object and transmitting a control signal to the driving module; and the driving module is used for receiving the control signal transmitted by the control module so as to drive the iris module to move until a vertical field angle theta of the iris module covers the height grade corresponding to the height of the to-be-measured object. Aiming at the technical problem that the height coverage range of an iris positioning technology in the prior art is not wide enough, the iris positioning method and the iris positioning system can achieve the whole-body high-range coverage of a user, and achieve the iris recognitionand acquisition.

Description

technical field [0001] The invention relates to the technical field of iris positioning, in particular to an iris positioning method, its system and an iris lock. Background technique [0002] The iris remains unchanged after the formation of the fetal development stage, which determines the uniqueness of iris characteristics and also determines the uniqueness of identification. Therefore, the iris feature of the eye can be used as the identification object of each person. In order to improve the security of access control, it is more and more popular to apply iris recognition to access control unlocking (ie iris lock). [0003] In the prior art, iris features are often used for unlocking. The Chinese utility model patent application number 201820625153 discloses an iris lock, which completes iris recognition for people of different heights by forming an oblique angle on the structure. At present, most of the iris locks on the market are similar to the Chinese utility mode...
