The DMD panel and DMD controller comprise a module that may drive the GPU to output shade pictures. The DMD permits high-speed calculation of holograms and drives the DMD panel as a spatial gentle modulator (SLM) for show.
SSD: SSD is used as a storage medium with quick knowledge studying and storage functionality. All computational holograms (CGH) for holographic video are pre-computed and saved within the SSD. Such storage helps high-speed playback of holographic movies by lowering knowledge entry time, permitting every packed body to be rapidly loaded and decompressed.
Excessive-speed CGH computation: Excessive-speed CGH computation is required to attain visible persistence results. The artificial shade CGH generates artificial shade CGH by synthesizing six RGB binary CGHs, which is used to drive the DMD panel as SLM, whereas the binary CGH packing expertise is used to cut back the quantity of information saved in SSDs and optimize the computational effectivity of holographic video.
Spatio-temporal multiplexing method: The unique 3D mannequin is spatially divided into many sub-objects, by the use of electro-holography. In every body, the CGHs of the corresponding sub-objects Div-1 to Div-N are generated utilizing the spatio-temporal division multiplexing method and displayed on the SLM to appreciate the 3D picture reconstruction of every sub-object.
The technical framework of WiMi’s DMD-SSD high-speed digital hologram playback expertise makes full use of some great benefits of DMD and SSD, and realizes extremely environment friendly and clear hologram video playback by way of high-speed CGH computation and space-time division multiplexing expertise.
Information pre-processing and storage: Information pre-processing and segmentation are carried out for 3D objects containing many object factors. The unique 3D mannequin is spatially divided into a number of sub-objects and corresponding CGHs are generated for every sub-object. these CGH knowledge are pre-calculated and saved in SSDs, and the packing strategy of binary CGHs is utilized to cut back the quantity of saved knowledge with a view to optimize the cupboard space and enhance the studying effectivity.
Excessive-speed CGH computation and synthesis of shade CGH: This adopts a number of optimization methods to enhance computational effectivity. First, a high-performance laptop system is utilized for CGH computation, which reduces the time price of CGH computation by optimizing the algorithm and computation course of. Second, an artificial shade CGH method is integrated to synthesize six RGB binary CGHs into one CGH, which reduces the quantity of computation and improves computational effectivity. As well as, within the pre-processing stage, the quantity of information required for computation is lowered by spatial segmentation and knowledge processing of the 3D mannequin, which additional optimizes the CGH computation course of. By way of the mixed utility of those optimization methods, the method efficiently achieves high-speed CGH computation, which gives sturdy assist for the real-time technology of high-definition holographic movies.
The belief of spatio-temporal multiplexing: In every body, the house of the unique 3D mannequin is partitioned into many sub-objects, the corresponding CGH is generated for every sub-object, and the 3D picture of every sub-object is reconstructed and displayed on the SLM by way of the collaborative work of the DMD panel and the DMD controller. By way of the spatio-temporal multiplexing method, the degradation of 3D video reconstructed from 3D objects containing many object factors is prevented, and the picture high quality of the holographic video is assured.
DMD-SSD: The pre-calculated CGH knowledge saved in SSD is transformed into high-definition, high-quality holographic video by way of high-speed knowledge loading and decompression, quick CGH calculation and synthesized shade CGH expertise. The DMD, as one of many key parts, drives the SLM to show the synthesized shade CGH, which realizes the high-speed digital digital playback of holographic video.
WiMi’s DMD-SSD high-speed digital hologram playback expertise must be additional optimized and improved. By way of expertise, the velocity and effectivity of CGH computation are improved by optimizing the algorithm and computation course of, and the computation price is additional lowered. As well as, analysis on holographic video knowledge compression and storage is strengthened to additional enhance the effectivity of information storage and studying. By way of steady technical optimization and enchancment, the efficiency and reliability of the expertise will be additional enhanced to increase its utility areas and market prospects. With the continual improvement and maturity of hologram expertise, WiMi’s DMD-SSD high-speed digital hologram playback expertise is predicted to turn into an essential breakthrough level and technical assist within the discipline of holograms. Extra revolutionary functions and merchandise primarily based on this expertise are anticipated to emerge sooner or later.
As an rising hologram expertise, DMD-SSD high-speed digital digital holographic playback makes full use of some great benefits of digital micromirror gadgets and solid-state drives, and efficiently realizes high-speed, high-definition holographic video storage, computation and playback by the use of the synthesized shade CGH and binary CGH packing expertise, in addition to space-temporal multiplexing expertise.
