Embodiment example 1

[0034] The naked-eye 3D TV is composed of a 3D image processing unit (1), a naked-eye 3D display screen (2), and a position detection unit (3). In this example, the naked-eye 3D display screen (2) is a 65-inch 4K LCD TV equipped with a 40LPI 4mm focal length lenticular grating, and the grating inclination angle θ is about 20°. The position detection unit (3) is located directly above the naked-eye 3D display screen (2), adopts a single camera, and can capture an image of the audience position, identify the number of audience (7) and the position distribution of the eyes (8) from the image, and from the image The optimal viewing distance L of the audience is estimated. The 3D image processing unit (1) is a highly integrated image processing host, which automatically selects the display mode according to the information sent by the position detection unit (3), and automatically selects the display mode according to the current optimal viewing distance L and the crosstalk area (4...

Embodiment example 2

[0037] In order to realize 3D social and remote video call functions, the function of the position detection unit (3) is provided by dual cameras, which can be raised and lowered to hide. The real-time recorded video is not only used to identify the distance and position of the audience, but also used by the 3D image processing unit ( 1) The synthetic 3D video stream is sent to the calling party through the high-speed network, and displayed on the naked-eye 3D display screen (2) of the other party, so as to realize the 3D video call in the 5G network environment. Glasses-free 3D TVs with video calling and social functions, in addition to meeting the public display function, are more suitable for home use. The naked-eye 3D display screen (2) used in public places is equipped with a grating with a larger grating pitch, which is more functionally focused on multi-viewpoint display and multiple viewing. When one person watches, it switches to two-viewpoint display mode. Automatica...

Abstract

The invention discloses a naked eye 3D display device and a multi-mode display method. The naked-eye 3D display device is composed of a 3D image processing unit (1), a naked-eye 3D display screen (2)and a position detection unit (3), wherein the position detection unit (3) records and analyzes position distribution of audiences in front of a display in real time; the 3D image processing unit (1)automatically selects from a double-viewpoint display mode, a multi-viewpoint display mode and a 2D display mode according to the position distribution situation; the naked-eye 3D display screen (2) is switched to a suitable display mode; the problem of dizziness caused by the existence of a crosstalk area is solved, and the watching comfort and degree of freedom are improved. The multi-mode display method not only improves the dizziness problem faced by naked-eye 3D display public display, but also provides powerful technical support for naked-eye 3D display to enter families and social televisions to enter 3D and 5G times.

Description

Technical field: [0001] The invention relates to a naked-eye 3D multi-mode display method, which can be used for 3D display of images and videos such as naked-eye 3D TVs, splicing screens, and large LED screens. Background technique: [0002] The biggest advantage of naked-eye 3D display technology is to get rid of the shackles of glasses, and it has begun to be used in small-scale commercial applications. From a technical point of view, naked-eye 3D can be divided into four types: Barrier, Lenticular Lens technology, Directional Backlight and direct imaging. After several years of development, Lenticular Lens (referred to as Lenticular Lens) Technology has become the main optical material to realize naked eye 3D display. The application of naked-eye 3D on the display screen can be divided into two categories: two-view technology based on personal terminals such as mobile phones, Pads, and notebook computers, and multi-view technology based on public displays such as TVs, s...
