Large-depth-of-field head-mounted VR optical system and imaging method thereof

Abstract

The invention provides a large-depth-of-field head-mounted VR optical system and an imaging method thereof. The large-depth-of-field head-mounted VR optical system comprises a first polarization analysis compound lens, a second polarization analysis compound lens, a first display screen, a second display screen, a first polarizing reflector and a second polarizing reflector; the first display screen and the second display screen are oppositely arranged on the two opposite sides of a segmentation datum plane, the main optical axis of the first polarization analysis compound lens and the main optical axis of the first display screen intersect at the first polarizing reflector, and the main optical axis of the second polarization analysis compound lens and the main optical axis of the second display screen intersect at the second polarizing reflector; each polarization analysis compound lens comprises a concave lens, a convex lens and a polarization analysis film, and one surface of the convex lens is tightly connected with one surface of the concave lens; each polarizing reflector includes a mirror and a polarizing film. According to the invention, a three-dimensional display image can be formed, the optical path of imaging light can be effectively improved, good depth-of-field distinguishing is obtained, dispersion of finally emitted light can be effectively eliminated, and adverse reactions such as dizziness caused by long-time use of a user are avoided.

Description

technical field [0001] The invention relates to a head-mounted VR, and specifically discloses a head-mounted VR optical system with a large depth of field and an imaging method thereof. Background technique [0002] VR (Virtual Reality), that is, virtual reality technology, is a virtual information environment that can be created in a multi-dimensional space using computer, display, and sensor technologies, enabling users to have an immersive sense of immersion. VR mainly includes multiple aspects such as simulated environment, perception, natural skills and sensing equipment. The simulated environment is a real-time dynamic three-dimensional realistic image generated by a computer; perception means that an ideal VR should have the perception that all people have; Natural skills refer to people's head rotation, eyes, gestures or other human behaviors, and the computer processes the data adapted to the participants' movements and responds to the user's input in real time; the...

Problems solved by technology

The traditional VR display system includes a screen and lenses. This kind of VR device is worn on the user's head, and its volume cannot be too large. Due to the limitation of the volume of the VR device, the depth of field of the head-mounted VR device in the prior art is limited. , unable to provide users with a highly immersive experience
