Field depth recognition optical device and imaging method for virtual reality 3D scene

Abstract

The invention discloses a field depth identification optical device for a 3D (three-dimensional) virtual reality scene and an imaging method of the field depth identification optical device. The device comprises a power supply, a variable focus lens set, two reflective mirrors and two display screens, wherein the variable focus lens set is arranged in front of human eyes; the reflective mirrors are symmetrically arranged in front of the variable focus lens set; an included angle of 50-70 degrees is formed between the reflective mirrors; the display screens are correspondingly arranged on the outer sides of the reflective mirrors; the power supply is connected with the variable focus lens set and the display screens. The imaging method comprises the following steps: mirror images having parallax are played by the display screens at the same time, reflected through the reflective mirrors and refracted through the lens set and then enter the human eyes, and a 3D image different in distance is generated in human brain by amplifying the parallax of the images of the display screens, so that the 3D virtual reality scene is generated in the human eyes. The field depth identification optical device adopts an ingenious optical design, so that the whole device is simple in structure, small and portable, can be mounted on the head, and can be better popularized in the fields of domestic entertainment and healthy diagnosis and treatment.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to a depth-of-field recognition optical device and an imaging method thereof for a virtual reality 3D scene. Background technique [0002] Virtual reality 3D scene display includes 3D entertainment games and film and television program appreciation, which is a hot spot in the current technology field. However, at present, the display of 3D stereoscopic images generally requires large-scale 3D stereoscopic movie projection systems (such as movie theaters or home theaters, etc.), which cannot be miniaturized and are not light enough, so it is difficult to realize simple and light portable devices such as household handheld or wearable devices. Way. [0003] In addition, according to current reports, some large Netcom companies are planning to launch some wearable virtual reality 3D glasses for displaying games or videos in the next few years, but according to their reports, t...

However, at present, the display of 3D stereoscopic images generally requires large-scale 3D stereoscopic movie projection systems (such as movie theaters or home theaters, etc.), which cannot be miniaturized and are not light enough, so it is difficult to realize simple and light portable devices such as household handheld or wearable devices. Way

[0003] In addition, according to current reports, some large Netcom companies are planning to launch some wearable virtual reality 3D glasses for displaying games or videos in the next few years, but according to their reports, the structure only uses one display screen, and in actual use , these structures do not have the function of depth recognition, so their three-dimensional effect is not satisfactory
