All-sight image display device

Abstract

The invention discloses an all-sight image display device. Image display equipment comprises a pupil adjusting mechanism, a concave lens, a convex lens and a transparent connecting element, wherein the pupil adjusting mechanism is arranged at one side of the image display equipment, the concave lens, the convex lens and the transparent connecting element are arranged at the other side of the image display equipment, the concave lens is arranged next to the display equipment, the transparent connecting element fixes the convex lens onto the concave lens, the image processing is divided into a segmentation step and a conversion step through image processing software, an original image is segmented into a center region and a peripheral region, an image in the center region enters pupils after being refracted through the convex lens and corresponds to the view sight comfortable vision field, and the image of the peripheral part is subjected to polar coordinate inversion through a computer and then enters the pupils through the concave lens. The all-sight image display device has the advantages that an all-sight image is generated through the combination of the concave reflecting lens and the convex lens, the visible range is enlarged, the ultra-large view sight within 230 degrees can be realized, the virtual reality telepresence is greatly improved, after the design is completed, the structure is simple, the assembling and manufacturing difficulty is reduced, the mass production is convenient, and the cost is reduced.

Description

technical field [0001] The present invention relates to an image display device, in particular to a display device for viewing full-view images. Background technique [0002] In recent years, with the continuous improvement of CG technology (Computer Graphic, computer graphics image technology) and computer performance, display devices for virtual reality have increasingly attracted people's attention. Among them, compared with CAVE (Computer-Aid Virtual-reality Environment, computer-aided virtual reality environment) and Full-Dome Projection (dome projection), HMD (Head-Mounted Display, head-mounted display system) has a higher cost. Inexpensive and easy to implement, it is more suitable for small units and personal use. Coupled with the increasing development of interactive media such as virtual roaming and computer games, the development prospects of head-mounted display systems with gesture sensing and 3D stereoscopic display functions are very broad. [0003] Due to s...

[0004] And existing similar equipment mostly adopts single convex lens or lens group as eyepiece, as figure 1 As shown, the original image produced by LED, LCD and other display devices is enlarged to a larger size and corrected to the distance of vision. This structure is limited by the diameter of the eyepiece and cannot display an image with a full viewing angle of 180 degrees.
