Three-dimensional naked eye suspension display system and method based on negative parallax

Abstract

The invention provides a three-dimensional naked eye suspension display system and method based on negative parallax. The three-dimensional naked eye suspension display system comprises a plurality of projection machines which are annularly arranged around a directional screen and used for providing parallax images, the directional screen which is arranged in front of the projection machines and used for conducting image processing on the parallax images provided by the projection machines, a motor which is connected with the directional screen through a rotating shaft and used for driving the directional screen to rotate at a predetermined speed, and an image display area which is located in front of the directional screen and used for conducting three-dimensional displaying on the processed images. According to the system and method, the directional screen is driven by the motor to rotate at a high speed, the projection machines are arrayed around the rotating shaft, when the directional screen directly faces one of the projection machines, the projection machine exits pupil for imaging, and an observation belt is formed above a displayer; hence, when the motor rotates by a circle, an entire circle is surrounded by the formed observation belt, the viewing range is effectively increased, circular viewing is achieved, meanwhile, the three-dimensional images can be viewed in a multi-person and multi-angle mode, and man-machine interaction is improved.

Description

technical field [0001] The invention relates to the technical field of naked-eye stereoscopic display, in particular to a naked-eye suspended stereoscopic display system and method based on negative parallax. Background technique [0002] There are many ways for people to perceive the objective world. The 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. Three-dimensional display technology provides visual information compared with the real world, allowing people to perceive the three-dimensional world, which greatly facilitates people's visual e...
