Embodiment Construction

[0027] In order to further illustrate the present application, the following examples are provided with the VR helmet as an example to introduce the relevant structure of the virtual reality head-mounted device of the present application:

[0028] figure 1 It is a side sectional view of a VR helmet provided by an exemplary embodiment of the present application. like figure 1 As shown, the VR helmet can include: a device body 1, which is equipped with a convex lens 2 and a VR playback component 5; further, a half-reflective half-lens sheet 3 for reflecting infrared light is also installed in the device body 1 , the half-reflective lens sheet 3 is positioned at the side of the convex lens 2 close to the user (that is, the half-reflective lens sheet 3 is positioned between the convex lens 2 and the user's eyes 6), because the half-reflective lens sheet 3 has a high transmittance to visible light Transmittance (relative to infrared light), and has low transmittance (relative to ...

Abstract

The application provides a head-mounted virtual reality device. The device comprises a device body which is internally equipped with a convex lens. The device further comprises a camera assembled in the device body, and a semi-reflecting and semi-transmitting lens used for reflecting infrared light. The semi-reflecting and semi-transmitting lens is disposed at a side, near a user, of the convex lens. The surface of the semi-reflecting and semi-transmitting lens is arranged obliquely so that an infrared image of the eyes of the user can be obliquely reflected towards the camera. Through the technical scheme, the acquisition accuracy of an infrared image of the eyes of a user can be improved.

Description

technical field [0001] The present application relates to the technical field of virtual reality, in particular to a virtual reality head-mounted device. Background technique [0002] VR (Virtual Reality, virtual reality) technology is a technology that comprehensively utilizes computer graphics system and various control interfaces to generate an interactive three-dimensional interactive environment on the computer and provide users with a sense of immersion. In related technologies, a user can obtain a corresponding virtual reality experience by wearing a virtual reality head-mounted device, such as VR glasses, a VR helmet and other VR devices. [0003] Due to the particularity of the VR scene, the technical solutions used in traditional electronic devices such as mobile phones and PCs are often not suitable for the VR scene. For example, when it is desired to collect infrared images of the eyes of a user wearing a VR device, due to the structural limitations of the VR de...
