Abstract

The invention discloses an iris detection method for a door lock device, and the door lock device comprises: an iris sensor which comprises a CCD imaging chip, a lens, and a lens rotating device for rotating the lens; a door lock processing modulewhich is used for processing iris data acquired by the iris sensor; a height acquisition module which is used for detecting the height range of the user. The iris detection method comprises the following steps: acquiring height data of a user; controlling the lens rotating device to rotate the angle of the lens relative to the imaging plane of the CCD imaging chip according to the user height data; and using the CCD imaging chip to collect iris data. The iris detection method of the door lock device has the beneficial effect that the detection range of the iris sensor can be intelligently adjusted according to the height of a user.

Description

technical field [0001] The present application relates to a detection method, in particular to an iris detection method of a door lock device. 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 model patent with the pa...
