Product Overview
The Q31 iris recognition chip takes Homsh Technology’s PhaseIrisTM 3rd-generation iris hard-core engine technology as its core, providing a cost-optimized single-chip solution for iris recognition and matching applications. It balances performance and cost, suitable for lightweight iris recognition scenarios such as smart door locks and private storage.
Performance Features
1. Core Acceleration Technology: Adopts PhaseIris Gen3 iris hard-core acceleration technology (area optimization mode) to ensure the efficiency of iris data processing while controlling costs.
2. Interface and Camera Support:
Provides GPIO/IIC interfaces.
Supports 1 parallel-port camera input, with a maximum support of 5 million pixels; integrates ISP, supporting functions such as automatic exposure, channel balance, and image cropping.
3. Matching and Image Output:
Supports QSPI Flash read template matching, up to 4,000 templates/s.
Supports DVP digital image output, up to 2 million pixels.
Application Fields
● Smart Terminal Security: Suitable for devices such as smart door locks, safes, and private storage cabinets to realize iris recognition-based identity verification and secure access.
● Lightweight Information Systems: Can be used in scenarios such as information login terminals to provide iris-level security for personal private data access.
Why Choose Q31?
1. Balance Between Cost and Performance: Based on the "area optimization mode" of PhaseIris Gen3 hard-core technology, it ensures core iris processing capabilities while controlling costs.
2. Adaptation to Lightweight Scenarios: 1 parallel-port camera input + DVP output + 4,000 templates/s matching speed, perfectly matching the needs of lightweight scenarios such as smart door locks and private storage.
3. High Security and Precision: FAR < 10−7, FRR < 10−3, and full-process iris algorithms (localization, liveness detection, matching, etc.) ensure the security and accuracy of identity verification.
