Problems solved by technology

However, the volumetric 3D display has the characteristic of non-blanking, that is, the front and back objects in the volume space cannot be blocked
This method can only display transparent objects, and cannot achieve perspective occlusion of spatial objects

Embodiment Construction

[0020] The three-dimensional display device of the panoramic view field based on the high-speed projector can realize the three-dimensional display of the panoramic view field. The 3D display of the panoramic field of view is to display the images of the various fields of view of the three-dimensional object at different angles of view on the screen. The rotation of the system components realizes the display of a 360° field of view. Due to the limitation of the light-emitting angle of each field of view image, each field of view It can only be observed at the corresponding position of the field of view to ensure that the left and right eyes can see images of different fields of view, so that the observer can produce stereoscopic vision. This method has the characteristics of realizing perspective blanking, horizontal 360° visibility, and multiple people watching around with naked eyes.

[0021] like figure 1 As shown, a high-speed projector-based panoramic three-dimensional d...

Abstract

The invention discloses a three-dimensional display device of a full-view visual field based on a high-speed projector. The device comprises a high-speed projector, a transmission type directional diffusing screen, a reflector system, a rotation device, a sensor, a rotation synchronous detection module and an upper computer. The high-speed projector projects combined images of the horizontal 360-degree full-view visual fields of three-dimensional objects on the reflector system rotating at high speed, and the images are projected on the fixed cylindrical transmission type directional diffusing screen after the images realize the turning of light paths by the reflector system. The transmission type directional diffusing screen can control the divergence angle of outgoing light, the left eye and the right eye of an observer see images with different visual angles, and the three-dimensional display of the three-dimensional objects on the full-view visual field is realized. The rotation synchronous detection module detects a rotation signal, is communicated with the upper computer and ensures that the positions of the combined images and the position of the rotating reflector system are synchronous. The invention can realize that both eyes of the observer see images with binocular parallaxes in different positions, thereby realizing the three-dimensional display.

Description

technical field [0001] The invention relates to a display device, in particular to a high-speed projector-based panoramic view field three-dimensional display device. Background technique [0002] People's three-dimensional perception of objects is based on a variety of depth cues, mainly including binocular parallax, motion parallax, adjustment and other cues. The optical device or structure that can make human eyes produce binocular parallax can produce three-dimensional stereoscopic vision. The application of 3D display technology is also very extensive, and it has good development prospects in many fields such as medicine, geospatial intelligence, oil exploration, pharmaceuticals, construction, film and television entertainment, video communication, scientific display and product advertisement. Currently, 3D display technologies mainly include stereoscopic 3D display, self-stereoscopic 3D display, holographic 3D display and volumetric 3D display. Stereoscopic 3D displa...
