Title:
IRIS RECOGNITION DEVICE HAVING LIGHT-FILLING FUNCTION, RECOGNITION METHOD, AND METHOD FOR FILLING LIGHT
Document Type and Number:
WIPO Patent Application WO/2017/206932
Kind Code:
A1
Abstract:
Provided are an iris recognition device having a light-filling function, a recognition method, and a method for filling light. The iris recognition device comprises: an acquisition module (10) for acquiring an eye image; a processing module (20); and a light-filling module (30). The processing module (20) is used to send a control signal to the light-filling module (30) when the eye image satisfies a preset clarity level. The light-filling module (30) is arranged at one side or two sides of the acquisition module (10) to rotate according to the control signal, such that an optical axis thereof is aligned with an eye zone, and a rotation angle range is within a preset angle range. The angle range is a range of an included angle between the optical axis of the light-filling module (30) and a line connecting the light-filling module (30) with the acquisition module (10). The above method can solve a problem of acquisition difficulties and poor user experience resulting from a fixed optimal acquisition position. Moreover, the invention eliminates the need to manually adjust an angle position of a light-filling module, such that a recognition device has higher levels of automation and intelligence, reducing inconvenience for a user, improving user experience, and increasing efficiency during a recognition process.
