Embodiment Construction

[0032] A zooming 3D display technology proposed by the present invention. When applied to a head-mounted 3D display, the specific implementation method is as follows figure 2 Shown:

[0033] Equipment needed:

[0034] 1) The display device adopts a head-mounted 3D display 3, commonly known as "3D video glasses".

[0035] 2) Two cameras 2 are respectively placed above the left and right eyes and fixed on the head-mounted 3D display 3 .

[0036] 3) Host computer 1 for providing image sources and processing 3D images.

[0037] 4) The downlink data line 4 that transmits the zoomed 3D image from the host computer to the head-mounted 3D display; and the uplink data line 5 that transmits the left and right eyeball images from the camera to the host computer.

[0038] work process:

[0039] First, the camera located in front of the eye collects the eyeball image 6, searches for the circular dark area corresponding to the cornea in the eyeball image, and determines the offset 7 o...

Abstract

The invention relates to a zooming 3D (third-dimensional) display technique and aims to a zooming visual effect for spatial senses of human eyes. Specifically, relative positions of corneas of left and right eyeballs in the white parts of eyes are located through at least one camera, and a sight line intersection is calculated accordingly; a filter is used to perform different-level fuzzing to objects, different in distance, in a visual scene according to the position of the sight line intersection; in a 3D display, a fuzzed 3D image is displayed to simulate the eyes zooming in the reality. The zooming 3D display technique has the advantages that few hardware devices are required, only the cameras for measuring the angle of eyeball are added, the cost is low, and popularization is easy.

Description

technical field [0001] The invention relates to a zoom 3D display technology, which belongs to the field of 3D display. This technology adds a visual zoom function to the 3D display function, which can cooperate with 3D display devices to provide users with a more realistic visual experience. [0002] Background technique [0003] The human eye's spatial perception is derived from the parallax between the left and right eyes, which is called: parallax spatial perception; and the zoom of the lens is called: zoom spatial perception. [0004] The existing 3D display technology utilizes the principle of parallax to provide users with a sense of space due to parallax, while ignoring the impact of visual zoom on the sense of space. Therefore, the existing 3D display technology is actually a "fixed-focus 3D display technology", which cannot simulate the complete sense of space in the real environment. [0005] Examples include 3D displays and head-mounted 3D displays. The forme...
