Naked eye 3D display method based on human eye tracking and control system

Abstract

The embodiment of the invention discloses a naked eye 3D display method based on human eye tracking and a control system. The method includes the steps of obtaining coordinates of midpoints of both eyes of a viewer captured by a camera; determining the moving direction of both eyes of the viewer and the moving distance from preset reference coordinates by comparing the midpoint coordinates of botheyes with the pre-calibrated preset reference coordinates; according to the moving direction and the moving distance and by combination with the pre-calibrated initial offset of both eyes, performingtranslation on displayed content of a display screen, wherein the initial offset is the distance of the axis of an optical axis of the camera deviated from a drawing layout cycle central point with adrawing layout reference point as a starting point when the coordinates of the midpoints of both eyes are located at preset reference coordinates. Through the technical scheme, the displayed contentof the screen can move correspondingly with the movement of both eyes, the viewer does not need to deliberately search for the viewing position in a visual range, the crosstalk can be avoided, and anideal naked eye 3D effect can also be easily experienced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of 3D display, and in particular to a naked-eye 3D display method and control system based on human eye tracking. Background technique [0002] Glasses-free 3D display technology refers to a 3D display technology in which viewers can directly watch three-dimensional images with naked eyes without wearing special 3D glasses, presenting a 3D effect. Glasses-free 3D display technologies include lenticular gratings, slit gratings, liquid crystal lenses, etc. Currently, the most widely used is lenticular 3D display technology. The principle of lenticular 3D display technology is realized by attaching a layer of special lenticular lens in front of a conventional display. The pixels of the image under each cylindrical lens are divided into several sub-pixels so that the lens can project each sub-pixel in a different direction. When the user is viewing 3D display content, the left and rig...

Problems solved by technology

[0005] Therefore, based on the movement of the human eye position, the technical solutions provided by the existing technology require more parameters to be calibrated when arranging naked-eye 3D content, and the debugging efficiency is low, which is not conducive to the calibration requirements of a large number of devices.
