Virtual reality device and image correction method thereof

Abstract

The application provides a virtual reality device and an image correction method thereof. The image correction method includes: acquiring a function relationship between an imaging light field of a display screen and an imaging light field of a human eye; acquiring an actual imaging light field of the human eye; calculating a corrected imaging light field of the display screen according to the function relationship and the actual imaging light field of the human eye; and rearranging pixels of the display screen to obtain a corrected imaging light field of the display screen. According to the application, the pixels of the virtual reality device are rearranged based on different visions and thus the imaging light field required by the displaying is obtained, so that adaptability of users with different eyesight is improved; and the user can watch the image directly without wearing the correcting glasses, so that the dizziness is avoided.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a virtual reality device and an image correction method thereof. Background technique [0002] With the rapid development of virtual reality technology, more and more users use virtual reality equipment for viewing movies, games, teaching or simulation and other fields. One of the disadvantages of current virtual reality equipment is that the user is in a sealed visual environment after wearing the virtual reality equipment head-mounted display, but the two-dimensional display screen cannot give real three-dimensional information. What's more serious is that when viewing the display screen of a virtual reality device, the distance between the screen and the human eye is constant, so the focus remains unchanged, but different images will bring different "depth of field" information, however, this When the eye focus is not adjusted accordingly, when the balance of the v...

AI Technical Summary

Problems solved by technology

One of the shortcomings of current virtual reality equipment is that the user is in a sealed visual environment after wearing the virtual reality equipment head-mounted display, but the two-dimensional display screen cannot give real three-dimensional information

What's more serious is that when viewing the display screen of a virtual reality device, the distance between the screen and the human eye is constant, so the focus remains unchanged, but different images will bring different "depth of field" information, however, this When the eye focus is not adjusted accordingly, when the balance of the visual system is broken, it will easily lead to dizziness, nausea, vomiting and other discomfort symptoms

This is also one of the reasons why most virtual reality devices are prone to motion sickness

[0003] For people with vision problems (such as myopia or hyperopia), they need to wear vision correction glasses before wearing virtual reality equipment, which brings a lot of inconvenience to the viewers in wearing and experience.
