Description

Technical Field

[0001] The utility model relates to the technical field of iris recognition devices, in particular to a mixed signal interface device of an iris recognition intelligent chip. Background Art

[0002] Iris recognition equipment is a highly secure biometric technology device that uses an individual's unique iris features for identity verification. As part of the eye, the iris's complex texture, blood vessel layout and other details are highly unique to each person and remain unchanged throughout life. Iris recognition equipment captures iris images through a high-precision camera, and uses advanced image processing technology and pattern recognition algorithms to compare the captured iris information with pre-registered iris templates, thereby achieving fast and accurate identity verification.

[0003] When the interface of the existing iris recognition device is used, the devices connected through the interface are limited. When the iris recognition device needs to be used in conjunction with multiple third-party peripherals and modules, the lack of compatible interfaces reduces the applicability of the iris recognition device. When a certain interface fails or fails, it is impossible to switch to the backup interface to continue working, which reduces the fault tolerance and stability of the system. Therefore, a mixed signal interface device for an iris recognition smart chip is needed to meet people's needs. Utility Model Content
