Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0034] Such as Figure 1-3 As shown, the present invention is a continuous parallax and wide viewing angle three-dimensional light field display device based on a pinhole array, comprising: a high-brightness LED backlight screen 1, a light field bottom figure 2 , light-transmitting medium 3 , pinhole array 4 .

[0035] The high-brightness LED backlight screen 1 in the device is used to increase the light transmittance of the pinhole array and improve the observation effect, and the brightness of the LED backlight screen reaches more than 20,000 nits.

[0036] The bottom of the light field in the device figure 2 , if it is generated by computer, please refer to the attached figure 1 , 2 . First, a camera array is used to collect multi-view images. The number of camera arrays is w×h, so the number of viewing angles of the light field image...

Abstract

The invention discloses a continuous-parallax and wide-viewing angle three-dimensional optical field display device based on a pinhole array. The device comprises a high-luminance LED backlight screen, an optical field base drawing, a light transmitting medium and the pinhole array. The above-mentioned parts are closely arranged in sequence and information of different directions of an image can be regenerated. When a watcher stands and moves in front of the device, different directions of an object in the image can be watched, moreover, viewing angles are changed continuously, and a viewing angle range can reach more than 90 degrees. The parallaxes of the image watched by left and right eyes of the watcher are different, a 3D effect is observed, and namely, according to the device, a naked eye 3D function can be realized.

Description

technical field [0001] The invention relates to a continuous parallax and wide viewing angle three-dimensional light field display device based on a pinhole array, which belongs to the technical field of light field display. Background technique [0002] Three-dimensional display and virtual reality technology have always been hot research topics at home and abroad. The traditional three-dimensional display technology is mainly based on the principle of binocular parallax. By wearing 3D glasses or VR (Virtual Reality) helmets, the left and right eyes can see images from different perspectives, so as to realize viewing to a 3D scene. However, this technology is difficult to solve the focusing problem of the human eye, and the parallax is discontinuous. Using this device for a long time will produce a very serious sense of vertigo. Integrated imaging technology is an emerging holographic three-dimensional display technology, which can restore the light information in the scen...
