Abstract
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for a virtual reality (VR) head-mounted apparatus are provided. One of the apparatus includes: a first convex lens on a side of the apparatus close to a user's eye when the user wears the apparatus, a partial-reflection partial-transmission lens located in the apparatus and on a side of the first convex lens away from the user's eye; and a camera located between the first convex lens and the partial-reflection partial-transmission lens. The partial-reflection partial-transmission lens is positioned and configured to reflect infrared light from the user's eye to the camera. The VR head-mounted apparatus improves the acquisition accuracy of an infrared image of an eye of the user wearing the apparatus.
