Problems solved by technology

[0004] By tracking the position of the stereo vision convergence surface, adjust the distance between the screen and the VR lens or AR optical structure in real time, and change the focus surface so that the focus surface is always on the same surface as the stereo vision convergence surface detected by eye tracking; however, to achieve this The optical system of the scheme requires a large amount of data calculation

Abstract

The invention discloses an optical system applied to a VRAR system and a focusing method of the optical system. The method includes the steps of on the basis of an eyeball tracing technology, detecting the position of a stereoscopic vision convergence plane of human eyes; after it is judged that the detected position of the stereoscopic vision convergence plane exceeds the range of a stereoscopicvision comfort area corresponding to the current focal length of the optical system, adjusting the focal length of the optical system, so that the detected position of the stereoscopic vision convergence plane reaches the range of the stereoscopic vision comfort area corresponding to the adjusted focal length. The optical system and the method can effectively reduce the amount of calculated data when solving a convergence conflict problem in order to reduce the cost caused by calculation overhead.

Description

technical field [0001] The present invention relates to the technical field of VRAR, in particular to an optical system applied in a VRAR system and a focusing method thereof. Background technique [0002] When viewing the 3D objects displayed by the VRAR (virtual reality, augmented reality) system, because the principle of viewing is that the left and right eyes see different displays of the same image through different stereoscopic display mechanisms (chromatic aberration, polarization or time-sharing), There is a parallax, and then the images are integrated through the brain to achieve a three-dimensional display. During this process, the two eyes focus on the screen or the virtual image plane through the lens adjustment, but after the brain is integrated, the eyes need to converge and rotate due to the depth difference between the three-dimensional object and the screen or virtual image plane. In the process of continuously watching dynamic 3D images, if the eyes freque...
