A remote iris recognition device

Abstract

The invention discloses a long-distance iris recognition device, which comprises: a casing provided with a touch display screen and a long-distance iris recognition module, and a central control platform placed inside the casing; the touch display screen is used for Provide a man-machine visual interaction interface for the central control platform; the remote iris recognition module is used to collect the iris image of the user, and transmit the iris image to the central control platform; the central control platform is used for Monitor the iris recognition process, receive and process the iris image, and complete the iris recognition process. The invention integrates a long-distance iris recognition module, which can capture iris images in a long-distance range, making up for iris imaging when users perform iris recognition at different angles. Insufficient light and strong ambient light interfere with iris imaging, thereby significantly improving the effective distance of the iris recognition device.

Description

technical field [0001] The invention relates to the field of iris recognition devices. More specifically, it relates to a remote iris recognition device. Background technique [0002] Iris recognition has gradually become a research hotspot and development trend in the field of biometrics due to its significant advantages such as accuracy, stability, safety and non-contact. As the most advanced new biometric technology, compared with other biometric technologies such as fingerprints and faces, iris recognition currently has low public recognition and market share, and poor user experience in practical applications is one of the most important problems. The reason is that the effective recognition distance of mainstream iris recognition systems on the market is less than 0.5m, and they have strict requirements on conditions such as distance, posture, and ambient light. Therefore, in recent years, some research institutions have conducted related research on long-distance iri...

As the most advanced new biometric technology, compared with other biometric technologies such as fingerprints and faces, iris recognition currently has low public recognition and market share, and poor user experience in practical applications is one of the most important problems. The reason is that the effective recognition distance of mainstream iris recognition systems on the market is less than 0.5m, and they have strict requirements on conditions such as distance, posture, and ambient light. Therefore, in recent years, some research institutions have conducted related research on long-distance iris recognition technology. A lot of work has been done on the two long-distance iris recognition systems based on the camera array and the rotating pan-tilt, but there are still problems such as low iris image resolution, slow response, and inaccurate positioning. In order to improve the iris recognition distance, a variety of The device makes the entire iris authentication device bulky, which is not conducive to practical application
