Embodiment Construction

[0049] The present invention establishes and analyzes the model that influences the three-dimensional depth factor according to Pannong fusion and wave aberration theory, such as figure 1 Shown include the following steps:

[0050] Step 1: Combining the visual characteristics of human eyes and Pannong fusion theory, establish an ideal model of stereoscopic depth. First, determine the parallax range in which both eyes can fuse to form a 3D sense. Define the parallax angle between -0.2°~+0.2° as the binocular parallax fusion range , where the parallax angle is the difference between the convergence angles of the two eyes. Positive parallax angles correspond to screen exits, and negative parallax angles correspond to screen entry. Screen exits have a greater impact on viewing experience, and the analysis methods for screen entry and exit screens are similar. The following analysis takes exit screens as an example.

[0051] Such as figure 2 The schematic illustration of the par...

Abstract

The present invention discloses a method of analyzing the stereo depth influence factors of a naked eye 3D display system. The method is characterized by according to the Panum's fusion and wave aberration theories, establishing an ideal stereo depth model and an actual stereo depth model, analyzing the factors influencing the actual stereo depth, and evaluating the stereo depth of the display system objectively, and comprises the following steps of S1 combining the human visual characteristics and the Panum's fusion theory to determine a parallax range within which the eyes can fuse to form a 3D experience, and establishing the ideal stereo depth model; S2 according to the wave aberration theory, establishing the actual stereo depth model, and calculating the actual stereo depth by the light spot distribution on the retinas and the monocular resolution limit of the people; S3 comparing the actual stereo depth and the ideal stereo depth, and analyzing the factors influencing the actual stereo depth. According to the present invention, the factors influencing the stereo depth of the naked eye 3D display system are analyzed systematically, and the bases for designing the naked eye 3D display system better and improving the experiences of the naked eye 3D display system are provided.

Description

technical field [0001] The invention relates to the field of naked-eye 3D display effect evaluation, in particular to a method for analyzing factors affecting naked-eye 3D stereoscopic depth. Background technique [0002] In recent years, 3D display technology with depth information has attracted extensive attention. People hope that the real three-dimensional world can be completely restored on the display screen, and the vivid look and feel can be obtained to the greatest extent while obtaining the required basic information. Virtual reality technology (Virtual Reality, VR) has been placed with great expectations and can be used in fields such as games, sports, online education, medical care, catering and online shopping. Technology giants such as Apple, Google, Oculus, Huawei, Samsung, and Microsoft have invested in this research, and technology rookies such as Ant Vision Technology, Baofeng Magic Mirror, and 7D Technology are also developing special displays. However, ...
