Title:
BIOMETRIC SYSTEM FOR XR HEAD-MOUNTED DISPLAY
Document Type and Number:
WIPO Patent Application WO/2024/093308
Kind Code:
A1
Abstract:
Disclosed in the embodiments of the present application is an eye/iris identity authentication system for an extended reality (XR) head-mounted display. The system includes an eye/iris imaging optical unit, a display imaging optical unit, a near-infrared illumination optical unit, and an eye/iris image imaging control unit mounted in the head-mounted display, where the eye/iris imaging optical unit is used for physical imaging of near-infrared incident light of an eye/iris, for the display imaging optical unit, an image display source image is emitted to the human eye for image projecting by means of optical path imaging of a display imaging assembly, the display imaging assembly controls an illumination radiation angle and an illumination angle of emergence of a light-emitting diode (LED) by means of an angle optical assembly to generate related near-infrared light which is emitted to the human eye for illuminating the eye/iris, and the eye/iris image imaging control unit is configured to control the eye/iris imaging optical unit and the near-infrared illumination optical unit to generate an eye/iris image in a combined imaging mode. the embodiments of the present application can optimize the eye/iris imaging image quality, improve an eye/iris imaging image speed and improve a recognition rate.
