Problems solved by technology

However, for the 360° three-dimensional display system, to further improve the resolution of the system, the existing high-resolution spatial light modulator and high-speed data processing system can no longer meet the demand for higher resolution
Unable to achieve higher resolution requirements, the surface of the 3D image is grainy, and the imaging range is small and other problems cannot be solved, which will affect the realism of the 3D image and reduce the visual experience of the observer

Abstract

The invention discloses a 360-degree three-dimensional display device based on splicing of multiple high-speed projectors. The 360-degree three-dimensional display device comprises an orientation diffuser screen set, a rotating device set, a rotating detection module, a projection splicing integration module, image storage modules and the N high-speed projectors. An algorithm of splicing of the multiple high-speed projectors is used for calculation to obtain a two-dimensional frame image sequence projected by each high-speed projector in real time, and the two-dimensional frame image sequences are sent to all the image storage modules. Under modulation of the rotating detection module, all the high-speed projectors are controlled to be matched with rotation of one set or more sets of orientation diffuser screens, splicing and synthesizing imaging of projection areas of all the high-speed projectors are achieved, and the space resolution ratio of three-dimensional display is improved in a multiplied mode. The algorithm based on splicing of the high-speed projectors is matched with the orientation diffuser screens for imaging, the three-dimensional imaging space is enlarged, the transverse dimension, the longitudinal dimension and the field depth dimension of a three-dimensional image are increased, and spatial expansion of three-dimensional display of the large-dimension space is achieved.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional display, and in particular relates to a high-resolution 360° three-dimensional display device and a display method based on splicing of multiple high-speed projectors. Background technique [0002] Human beings use vision as the first way to contact and understand the world. Vision is also the primary source of information for human beings. Therefore, the presentation and expression of visual information is particularly important in the development of today's information age. However, different from the normal way of human observation, the main means of expressing visual information is still two-dimensional. The traditional two-dimensional display technology removes the depth information of the actual object. Dimensional information will have obvious discomfort and contradiction. Similarly, human beings are constantly pursuing a real spatial 3D display experience, and related 3D display...
