Problems solved by technology

[0003] There are following defects in the existing passive stereoscopic system: 1. There must be two synchronously input signal sources; 2. The display area is limited, and a more high-definition and wider display area cannot be realized; 3. The input film source is limited, Only by inputting 3D images can the viewing of the stereoscopic effect be realized; 4. The display area is limited to flat display and does not support curved surface display; 5. The viewing angle and depth of field cannot be adjusted

Embodiment 1

[0022] The 2D signal source is input to the stereoscopic image processor (2) through the digital video transmission cable (HDMI / DVI) (1), and the stereoscopic image processor (2) adopts grating separation technology to form passive stereoscopic projection left and right eye signals;

[0023] The left and right eye signals of the passive stereoscopic projection are input into the passive stereo fusion processor (3) through the digital video transmission cable (HDMI / DVI) (1), and the passive stereo fusion processor adopts fusion and surface correction technology to generate The left and right eye signals that have been pre-corrected by the curved surface are finally output to the projection array (4);

[0024] The projection array (4) adopts optical polarization display technology to simultaneously project left and right eye signals onto the stereo fusion screen (6) in mutually perpendicular polarization directions. The viewer wears polarized 3D glasses (5) with...

Embodiment 2

[0029] The 3D signal source is input to the passive stereo fusion processor (3) through the digital video transmission cable (HDMI / DVI) (1), and the passive stereo fusion processor uses fusion and surface correction technology to generate a fusion band and a curved surface according to the projection surface Pre-corrected left and right eye signals, and finally output 4 channels of left and right eye signals to the projection array (4);

[0030] The projection array (4) adopts optical polarization display technology to simultaneously project left and right eye signals onto the stereo fusion screen (6) in mutually perpendicular polarization directions. The viewer wears polarized 3D glasses (5) with the same polarization direction as the projection array (the left lens has the same polarization direction as the signal from the left eye, and the right lens has the same polarization direction as the signal from the right eye), which can produce stereoscopic perception...

Abstract

The invention relates to a stereoscopic image display system, which belongs to the technical field of 3D high-definition stereoscopic display. The system is composed of a stereoscopic image processor, a passive stereoscopic fusion processor, a projection array, a stereoscopic fusion curtain and the like. The system is the only system at present to combine the passive stereoscopic fusion processor and the stereoscopic image processor for use, and through optimizing the 2D / 3D real-time conversion calculation technology, tension and fatigue due to long-time watching by eyes can be reduced. Through carrying out real-time and high-efficiency conversion on a 2D film source, the cost of a 3D shooting film source is reduced.

Description

technical field [0001] The invention relates to a stereoscopic image display system, which belongs to the technical field of three-dimensional high-definition stereoscopic display. Background technique [0002] The technology adopted in the existing passive stereo system is optical polarization display technology. The method of realizing this optical polarization display technology is: through two display devices (projectors), two images or films that have undergone special processing (stereoscopic processing) are projected synchronously, so that the two slightly different images (difference in depth of field) Superimposed on the screen (polarized optical screen). At this time, if you look directly with the naked eye, the picture you see is double and blurred. To see stereoscopic images, a polarizer needs to be installed in front of each projector. The light emitted from the two projectors passes through the polarizer to form polarized light. The polarization directions ...
