Embodiment Construction

[0036] Various details involved in the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be pointed out that the described embodiments are only intended to facilitate the understanding of the present invention, rather than limiting it in any way.

[0037] Such as figure 1Shown is the appearance of the true three-dimensional display system. The overall design of the true three-dimensional display system is integrated. The three-dimensional space 220 is the rotating display space of the motion display screen 110. The real three-dimensional image with real physical depth generated when the motion display screen 110 rotates is displayed in the X, Y, and Z three-dimensional space 220, and 230 is displayed in the X, Y, and Z three-dimensional space 220. In a three-dimensional image example of a three-dimensional space, the middle part of the chassis 200 and the X, Y, Z three-dimensional space 220 i...

Abstract

The invention relates to a real three-dimensional display system and a display method; an image projection device in a case is connected with a motion display screen arranged above the case; a display area of the motion display screen is arranged on the top of the case; the motion display screen intercepts two-dimensional image flow projected by the image projection device at different positions of a Z axis; the two-dimensional image flow forms 1-N two-dimensional images at different positions of the Z axis; the motion display screen rotates at the rotating speed of 480 to 600r / min, so that the two-dimensional images which are continuously intercepted at different positions of the Z axis are synthesized into a real three-dimensional image; the real three-dimensional image is displayed in an X,Y,Z three-dimensional space; and the invention randomly observes an scene to be observed in 360 degrees and is used to produce the real three-dimensional image with true physical depth in the three-dimensional space. The invention breaks through the bottleneck of three-dimensional display definition, so as to realize tens of millions of three-dimensional image body elements; the three-dimensional image is directly observed without any auxiliary equipment; and a rear projection type is adopted, the whole system is integrated, so as to facilitate transportation and maintenance.

Description

technical field [0001] The invention belongs to the technical field of true three-dimensional display, and relates to a system and a display method for realizing true three-dimensional display. Background technique [0002] Extensive research has been done in the prior art on the technology of laser scanning the rotating helical surface of the moving display screen 110 to generate a true three-dimensional image. In this method, a laser beam is scanned on a rotatable helical surface, and the reflection of the helical surface can generate visible light spots in three-dimensional space. A true 3D image is displayed. [0003] There are many problems with this true three-dimensional display method: the most prominent problem is its image clarity. Since laser scanning is performed sequentially, only one 3D voxel can be displayed at any one moment, so the number of voxels that can be displayed in a repeated refresh period is limited, otherwise the brightness of the voxel and the ...
