Naked eye suspended stereo display system based on Fresnel lenses and using method thereof

Abstract

The invention provides a naked eye suspended stereo display system based on Fresnel lenses and a using method thereof. The naked eye suspended stereo display system comprises a directional screen, a projection unit and a motor. The directional screen is composed of a Fresnel lens set and an optical grating. The Fresnel lens set comprises two Fresnel lenses which are sheets formed by polyolefin materials in an injection molding mode. One surface of each lens is a shiny face, and the other surface of the corresponding lens is carved with concentric circles from small to large. The projection unit comprises a plurality of minitype projectors, and the projection unit is arranged below the directional screen. Camera lenses of the projectors face the directional screen, the minitype projectors are arrayed around a rotating shaft and rightly face the directional screen to conduct projection, and the motor is arranged below the projection unit. The naked eye suspended stereo display system based on the Fresnel lenses can allow multiple persons to watch through naked eyes at any angle, observed stereo images are different when the persons stay at different positions, when the images are displayed on the screen, observers can touch the images with hands, and therefore good man-machine interactivity can be reflected.

Description

technical field [0001] The invention relates to a naked-eye suspended stereoscopic display system and a use method, in particular to a naked-eye suspended stereoscopic display system based on a Fresnel lens and a use method, belonging to the field of naked-eye stereoscopic displays. Background technique [0002] There are many ways for people to perceive the objective world. Eyes carry more than 90% of the information acquisition ability of human beings. The amount of information that can be obtained with the help of vision far exceeds the amount of information that can be obtained by other means such as hearing, touch, smell and taste. . Objects in reality are all three-dimensional and three-dimensional, and the visual system of the human eye can well adapt to the three-dimensional world in reality and accurately transmit image information to people. However, due to technical reasons, most of the current display devices can only display two-dimensional images. Although the...

Problems solved by technology

[0004] Although this technology has been developed for a long time, most of the existing stereoscopic displays cannot realize the characteristics of naked-eye viewing, peripheral vision, and image suspension and touch at the same time.
