Problems solved by technology

[0003] The current VR devices usually have the eye tracking function. The infrared camera is set on the side of the VR device close to the user to directly or indirectly capture images of the user's eyes to obtain the pupil position. However, in order not to affect the user's line of sight, the position of the infrared camera needs to be Far away from the user's line of sight, there are high requirements for the viewing angle and size of the infrared camera, high cost, and poor imaging quality

Abstract

The invention discloses a virtual reality display device. The device comprises a display screen for displaying a frame to a user, at least one infrared light source and an infrared camera; the infrared camera is arranged at the side, away from the eyes of the user, of the display screen and used for collecting an eye image of the eyes of the user under the irradiation of at least one infrared light source. The invention further discloses a sight angle calculation method and display equipment comprising the virtual reality display device. The requirement of the infrared camera for the eyeball tracking function of the display device is lowered, and therefore the cost is lowered; the eyeball imaging quality is improved, a photographing blind region is avoided, and then the eyeball tracking precision is improved.

Description

technical field [0001] The invention relates to the field of display technology. More specifically, it relates to a virtual reality display device, equipment, and a method for calculating a viewing angle. Background technique [0002] Virtual reality (Virtual Reality, VR) technology is a virtual environment based on immersion and conception, using computer technology as the core and relying on graphics and image processing means to simulate human vision, hearing and Touch and so on get the same feeling as the real world. [0003] The current VR devices usually have the eye tracking function. The infrared camera is set on the side of the VR device close to the user to directly or indirectly capture images of the user's eyes to obtain the pupil position. However, in order not to affect the user's line of sight, the position of the infrared camera needs to be Far away from the user's line of sight, the infrared camera has high requirements on the viewing angle and size, high ...
