Embodiment 1

[0034] Embodiment 1 of the present invention provides a single-eye 3D imaging display method, in which the image of the panel screen is demonstrated on the arc display surface following a parallel projection method.

[0035] Specifically, on the arc display surface, the pixel position of the panel screen image is demonstrated on the inner arc surface by means of optical refraction, optical fiber image guide or direct construction of an inner arc display screen on the panel screen image according to the rules of the parallel projection method. The relative positional relationship between the pixels of the panel screen image and the image pixels on the inner arc surface is, the radius of the pixel ring on the panel screen is r, and the radius of the arc display surface is R, then the pixel point and the inner arc surface vertex The distance on the inner arc surface is: 2πR*{arc sin (r / R)} / 360°. Similarly, on the same section, the distance between the center point of the screen an...

Embodiment 2

[0037] Embodiment 2 of the present invention also provides a monocular 3D effect imaging display method, which can also be demonstrated directly by comparing the visible range of the wearing device with the visible range of the experience scene in the application, without calculating the image projection stretch ratio.

[0038]First of all, it is necessary to determine the visible range of the device. When the device is worn, the angle between the display edge and the line of sight axis in the head-up state at the center of the pupil determines the visible range of the device (the included angle is generally not greater than 90°, and the total viewing angle is not greater than 180° °).

[0039] At the same time, it is necessary to determine the visible range of the scene. The visible range of photos and movies is determined by the maximum wide-angle value of the shooting equipment (generally not greater than 170°). The visible range of virtual data scenes is generally unlimited...

Embodiment 3

[0043] Figure 6 The application mode of the imaging and display device for monocular 3D effect provided by Embodiment 3 of the present invention in binocular 3D glasses is shown.

[0044] In the application of the imaging inner arc surface display technology of the monocular 3D effect, in the application of binocular use, the visual center point and the focal point of the image can be changed by physically rotating the lens or through the numerical control adjustment of the image playback control system. The specific angle of rotation is determined by the interpupillary distance P and depth of field D are jointly determined, and the optimal parameter of the rotation angle is: arc tan (P / 2D).

Abstract

The invention relates to the technical field of 3D display and particularly to an imaging display method and apparatus capable of achieving a monocular 3D effect and an application parameter thereof in binocular 3D glasses. The method comprises constructing an inner-arc display surface to obtain a super large viewing field, and projecting a demonstrated image onto the inner-arc display surface by using a parallel projection method. The projected image is naturally stretched by the inner-arc display surface so as to approach a real scene in a visual effect, thereby achieving a 3D imaging purpose.

Description

technical field [0001] The present invention relates to the technical field of 3D display, in particular to an imaging display method and device capable of realizing monocular 3D effect and its application parameters in binocular 3D glasses. Background technique [0002] In recent years, as virtual reality (VR) has been popularized by the media and the market, 3D glasses display technology has also received more and more attention and research. [0003] The existing 3D glasses technology is to install a flat-panel display on the left and right frames of the VR glasses, and use the angle difference between the left and right displays to play the scene to produce a certain 3D effect. 3D imaging. [0004] Its disadvantage is that the two display screens installed in the 3D glasses are located directly in front of the eyeballs. When observing objects, the axes of sight of the two eyes are forced to be in a parallel state and cannot converge at the same point. Focusing on the s...
