[0002] Biometric identification is the most convenient and secure identification technology currently. It does not require carrying any documents or remembering any passwords. It is a convenient, fast and reliable identification method. Biometric identification is a technology that identifies a person's identity through the physiological or behavioral characteristics inherent in the human body. Common biometric features include fingerprints, palm prints, irises, retinas, face shape, voice, handwriting, and DNA.

[0003] At present, the main means of identity recognition are fingerprint recognition and face recognition. Fingerprint recognition has high accuracy, but it is easy to imitate; face recognition technology has the advantage of being easy to use, but the accuracy is low and often cannot meet the needs of actual applications. Iris recognition is a recognition method that can ensure the accuracy, security and convenience of the recognition system in this context. During the use of existing iris recognition, the camera angle is relatively fixed and inconvenient to adjust. It cannot meet the adaptability of users of different heights and requires users to adjust their postures in coordination with the recognition camera. Utility Model Content
