Method, device, and electronic equipment for determining grating parameters of naked-eye 3D display equipment

Abstract

An embodiment of the invention discloses a method and a device for determining grating parameters of naked-eye 3D display equipment, and electronic equipment, which relate to the field of three-dimensional display technologies, and can be used for determining actual values of the grating parameters precisely. The method comprises the steps of: acquiring a first image acquired by means of an image acquisition device, and acquiring actual space coordinates of a center point of first-color fringes in the fringe image and a fringe period of the fringe image; acquiring space coordinates of an actual acquisition position of the image acquisition device, a distance between the image acquisition device and the display screen, a placing distance of the grating and pitch of the grating; and determining that the grating and a panel of the display screen are horizontally and relatively staggered according to the actual space coordinates of the center point of first-color fringes, the fringe period, the placing distance of the grating, the pitch of the grating, the space coordinates of an actual acquisition position of the image acquisition device, and the distance between the image acquisition device and the display screen. The method and the device can be used for improving the display effect of the naked-eye 3D display equipment.

Description

technical field [0001] The present invention relates to the technical field of stereoscopic display, in particular to a method, device and electronic equipment for determining grating parameters of a naked-eye 3D display device. Background technique [0002] People usually watch objects with both eyes at the same time. Due to the distance between the eyes of the human eye, the distance between the left and right eyes is about 65mm. , because the visual images received by the left and right eyes are different, the brain synthesizes the information of the two images of the left and right eyes to superimpose and regenerate the image, so that the viewer has a three-dimensional effect. At present, the mainstream naked-eye 3D (3-dimensional,) display device is to use the above principle, by superimposing a special grating on the conventional display, the grating can refract the image in different directions, so that the visual images of the left eye and the right eye are separated...

AI Technical Summary

Problems solved by technology

If the design values ​​are directly used for layout display, it will lead to inaccurate adjustment of the left and right eye viewing areas of the naked-eye 3D display device, which will affect the display effect of the naked-eye 3D display device

Take the relative dislocation between the grating and the display panel as an example. Ideally, the grating and the display panel should be precisely aligned. However, due to the problem of process accuracy, the grating and the display panel cannot be aligned when producing naked-eye 3D display devices. Accurate superposition, that is, the period of the grating and the initial phase of the RGB pixels of the panel cannot be unified. If the misalignment is not considered when laying out the image, it will have a great adverse effect on the display effect of the naked-eye 3D display device
