Embodiment Construction

[0042] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0043] The tracking type ground light field 3D display method with a super-large viewing angle of the present invention, such as figure 1 shown, including:

[0044] S1. Synthesizing a synthetic image for 3D display based on the parallax image of the 3D scene;

[0045] S2. Based on the orientation information of the observer, determine and display the composite image in S1 corresponding to the orientation information.

[0046] In the terrestrial light field display method, a light field system containing a lens array is usually selected.

[0047] In order to achieve jump-free switching between synthetic images, during the image acquisition process of S1, the parameter re...

Abstract

The invention provides a tracking type ground light field 3D display method having a super-large visual angle and a tracking type ground light field 3D display system thereof. The display method comprises the steps that S1. a composite graph used for 3D display is synthesized based on parallax images of a 3D scene; and S2. the composite graph corresponding to azimuth information is judged and displayed based on the azimuth information of an observer. According to the tracking type ground display 3D display method having the super-large visual angle, the field angle is enhanced to a great extent on the basis of ensuring high resolution so that the super-large visual angle can be realized. The display system has the advantages that the display system is simple in structure without scenario or other auxiliary optical devices, and the system has no mechanical motion and does not generate vibration, noise or jump.

Description

technical field [0001] The present invention relates to the technical field of 3D display, and more specifically, to a method and system for tracking 3D display of a ground light field with a super-large viewing angle. Background technique [0002] With the rapid development of today's science and technology, the traditional two-dimensional flat display technology is far from being able to meet the current needs of various industries for depth data and three-dimensional space. More and more application fields, such as medical imaging, scientific research, outer space exploration, important teleconferences and military, etc., require the real reconstruction of 3D scenes, so that the viewer can capture relevant information more accurately and accurately conduct Judgment on the spot. [0003] Using stereo glasses to realize binocular stereo is the most common 3D display technology at present, and this technology is mainly used in the film industry at present. The emergence of...
