Glasses-free 3D playing method and glasses-free 3D playing system based on human eye tracking

Abstract

The invention provides a glasses-free 3D playing method and a glasses-free 3D playing system based on human eye tracking. The method comprises the following steps: acquiring the coordinates of the midpoint of the eyes and the pupil distance of the eyes in an image with a face shot by a camera facing a screen watching area; calculating the physical distance between the midpoint of the eyes and the camera according to the pupil distance of the eyes by a default algorithm; determining a glasses-free 3D visual area where the eyes of the face are according to coordinates of the midpoint of the eyes and the physical distance between the midpoint of the eyes and the camera; making sure that the left eye of the face is in the glasses-free 3D right eye visual area and the right eye of the face is in the glasses-free 3D left eye visual area, and exchanging a left eye view and a right eye view in a glasses-free 3D image to be played; and playing the glasses-free 3D image after view exchange. By adopting the method and the system of the invention, an ideal 3D effect can be achieved for glasses-free 3D video or image watching from more angles of view. The algorithm for the physical distance between the midpoint of the eyes and the camera is obtained through optimization, and the consumption of hardware resource can be reduced.

Description

technical field [0001] The invention relates to the field of naked-eye 3D, in particular to a naked-eye 3D playback method and system based on human eye tracking. Background technique [0002] Glasses-free 3D display technology means that viewers can directly watch three-dimensional images with naked eyes without wearing glasses, presenting a 3D effect. There are several naked-eye 3D display technologies, and the current application solution that is really suitable for mobile devices is the lenticular lens technology. Lenticular lens technology is also known as lenticular lens or micro-cylindrical lens 3D technology, and its biggest advantage is that its brightness will not be affected. The principle of lenticular lens 3D technology is to add a layer of lenticular lens in front of the LCD screen, so that the image plane of the LCD screen is located on the focal plane of the lens, so that the pixels of the image under each lenticular lens are divided into several sub-pixels,...
