Abstract

An embodiment of the invention discloses an alignment method of an optical lens and a display screen in VR equipment and a system thereof. The alignment method comprises the following steps of according to an image parameter of a pre-generated pattern, generating a test pattern on the display screen; through the test pattern, aligning an optical center of the optical lens with a preset position of the display screen, and making an optical axis of the optical lens be vertical to the display screen; using an image acquisition apparatus to collect the test pattern imaged on the optical lens so as to acquire a correction pattern; displaying a reference pattern and the correction pattern on an independent observation interface; determining whether the reference pattern and the correction pattern are superposed; if the reference pattern and the correction pattern are superposed, determining that the optical lens and the display screen are aligned; and if the reference pattern and the correction pattern are not superposed, adjusting a relative position of the optical lens and the display screen so that the reference pattern and the correction pattern are superposed. In the invention, accurate alignment of the optical lens and the display screen can be realized, an imaging effect of the display screen in the VR equipment is guaranteed and an experience feeling of a user is increased.

Description

technical field [0001] The invention relates to the technical field of optical instruments, in particular to a method and system for aligning an optical lens and a display screen in a VR device. Background technique [0002] Virtual reality glasses equipment, referred to as VR glasses, is a smart device that emphasizes user experience. [0003] The structure of VR glasses on the market includes a frame body, mirror legs and two display screens, and the frame body and mirror legs are connected by a foldable mechanism. The two display screens are fixed on the mirror frame body. At the same time, an optical bracket is arranged in the mirror frame body, and optical modules respectively corresponding to the two display screens are installed on the optical bracket. Each optical module is arranged side by side with the display screen, and the axis of the optical module and the axis of the display are on the same straight line. [0004] When assembling existing VR devices, due to...
