AI Technical Summary

Technical Problem

In existing cattle identification technologies, the quality of iris and nose print images is unstable, making it difficult to achieve high-accuracy identity verification, especially in complex environments, leading to identification failures and low management efficiency.

Method used

By capturing iris images and nasal print texture data of cattle using an image acquisition device, and combining illumination calibration and signal processing methods, standardized image pairs are generated. Information fusion technology is then used to extract high-frequency features of the iris and nasal print codes to generate fused feature templates, enabling identity verification and location tracking.

Benefits of technology

In complex environments, it has enabled accurate identification of cattle and asset management, improved the efficiency and credibility of digital management in the livestock industry, and ensured the traceability and ownership of assets.

Abstract

This invention discloses a method and system for cattle identification based on iris recognition and nasal print recognition. By acquiring iris and nasal print images of cattle and combining them with illumination calibration processing, standardized image pairs are generated. Signal processing and binarization operations are used to extract high-frequency features of the iris and nasal print codes, which are then fused into complementary feature templates to handle complex scenarios such as image occlusion or changes in illumination. The identity of the cattle is confirmed through feature template matching, linked to lifecycle records, and updated in real time. A tracking module binds the records and coordinates to obtain livestock quarantine data. Finally, the system connects to financial scenario data in a remote management platform to determine traceability requirements and achieve asset ownership confirmation. This invention realizes a complete closed-loop management system from identity verification to asset ownership confirmation, significantly improving the efficiency and reliability of digital management in the livestock industry.
