Iris recognition device and method for dynamic human eye tracking

Abstract

The embodiment of the invention provides an iris recognition device and method for dynamic human eye tracking. The device comprises a processor, an iris image sensor, an iris coding recognition module, a ranging device, a sliding device, a rotating device, an object loading platform and a plurality of image acquisition devices. The iris image sensor is arranged on the rotating device to be rotated with the rotation of the rotating device. The iris image sensor, the iris coding recognition module and the rotating device are mounted on the object loading platform, and the object loading platform is arranged on the sliding device to move with the movement of the sliding device. The device actively adjusts the iris image sensor through the rotating device and the sliding device to track eyes of a use, thereby solving the problem of height self-adaptation, further solving the problem that the traditional iris recognition device requires the user to move the eyes to a designated iris recognition acquisition area, improving the usability of the iris recognition device and enhancing the sense of user experience.

Description

technical field [0001] The invention relates to the field of biological identification, in particular to an iris identification device and method for dynamic human eye tracking. Background technique [0002] With the development of biometric technology, traditional identification devices such as ID / IC cards are gradually replaced by biometric devices, such as fingerprint recognition devices, face recognition devices and iris recognition devices. Among them, the iris recognition device has been vigorously developed and applied because of its high security. In the prior art, a camera array composed of multiple cameras is used for image acquisition. When the number of cameras is small, it is difficult to meet the requirements of different user heights. If the number of cameras is large, it will increase the computational load of the computer, resulting in a longer recognition delay. Moreover, this collection method also requires the user to actively point the human eye at one...

AI Technical Summary

Problems solved by technology

In the prior art, a camera array composed of multiple cameras is used for image acquisition. When the number of cameras is small, it is difficult to meet the requirements of different user heights

If the number of cameras is large, it will increase the computational load of the computer, resulting in a longer recognition delay

And this collection method also requires the user to actively point the human eye at one of the cameras, the equipment is not intelligent enough, and the usability is not good

In addition, in the prior art, a lifting rod is also used to adjust the height of the device to meet the requirements of users of different heights. However, this adjustment method has a large range of motion and a long time delay, which may easily cause the iris camera to shake and cause the iris image to be unclear.
