Display method and display system for spatial three-dimensional video

Abstract

The invention discloses a display method for a spatial three-dimensional video. The display method comprises the following steps of: segmenting ordinary-frame-rate three-dimensional video data into multilayer ordinary-frame-rate two-dimensional video data with different depths; recombining the multilayer ordinary-frame-rate two-dimensional video data with different depths into high-frame-rate two-dimensional video data; projecting the high-frame-rate two-dimensional video data into a three-dimensional space full of micro particles by a projection method; and projecting linear light rays into the three-dimensional space full of the micro particles from a direction vertical to a projection direction, and simultaneously controlling projection positions of the linear light rays to synchronously change with positions in front of and behind the two-dimensional video data before segmentation so that a three-dimensional active video image can be formed in the three-dimensional space full of the micro particles. The invention also discloses a display system for the spatial three-dimensional video, and the display system comprises high-frame-rate two-dimensional video projection equipment, a closed three-dimensional space full of the micro particles, a linear light source capable of controlling the projection positions, and a computer for coordinating system work.

Description

technical field [0001] The invention relates to the technical field of stereoscopic video display, in particular to a spatial stereoscopic video display method and a display system thereof. Background technique [0002] With the development of technology, some display terminals displaying three-dimensional effects have appeared in the research field and consumer market. There are two main types. One is a display system that forms a three-dimensional picture in the brain according to the parallax of the human eye by wearing three-dimensional glasses; The second is to allow the eyes to see different pictures through physical optical devices to form a stereoscopic effect. Both of these methods are passive stereoscopic display methods, that is, the observer cannot independently choose the viewing angle and distance, and each observer can only see the same stereoscopic picture no matter what position and angle they are in, which is similar to the stereoscopic image in real life. ...

[0003] At the same time, large-scale event exhibitions now require more and more three-dimensional image display. The traditional method can only be used for flat display or three-dimensional physical display. In dim light or at night, three-dimensional objects must be displayed with the help of external light sources. However, the display is still not as good as it should be
