Research On Logic Algorithm Of Multi-view Naked-eye 3D Pixel Configuration For High Definition

Multi-view naked-eye 3D technology can meet the needs of 3D viewing,and it is a leading development direction of naked-eye 3D technology.Multi-view naked-eye 3D pixel reconfiguration technology can use digital logic method to complete the sub screen reconfiguration of multi-view pixels,which is one of the key technologies to realize multi-view naked-eye 3D.In this thesis,based on the research of naked-eye 3D technology of the research group,we further explore the technology of multi-view naked-eye 3D pixel reconfiguration,focusing on the hardware logic algorithm of HD multi-view naked-eye 3D pixel reconfiguration.The research work of this thesis is as follows:(1)Based on the research of naked-eye 3D technology,combined with the theory of independent view area and the method of sub screen partition,the optical mechanism of multi-view naked-eye 3D is discussed,and the optical structure and spatial distribution characteristics of independent view area are obtained.According to the sub screen partition and independent view area of multi-view 3D,the feasibility of high definition multi-view pixel reconfiguration logic algorithm is discussed.(2)The sub screen partition of multi-view 3D is reorganized by the physical column pixels of the flat panel display to form multiple sub screens.In this thesis,we take four view points as an example to describe the partition structure and independent view area distribution of the sub screen,and study the pixel reconfiguration method of multi-view video image to the sub screen partition through TTL video interface and HDMI video interface.Due to the large amount of data in multi-view 3D video,it is necessary to complete view segmentation,data buffering and pixel reconfiguration in a refresh cycle,which can not be completed by CPU method.Therefore,we build a video image processing circuit with FPGA as the core controller,with DDR as the cache,and use the round sequence algorithm to quickly complete the pixel reconfiguration of multi-view digital video image.(3)According to the design method of high-speed digital video processing IC(integrated circuit),according to the processing flow of multi-view digital video image,the hardware description language algorithm is divided into several functional modules.In the research,the logic algorithm design and debugging of system clock and reset logic module,display timing control logic module,stereo to image reading logic module,pixel reconfiguration logic module and HDMI interface control module are completed respectively.The optical structure and independent view area distribution of the multi-view naked-eye 3D technology studied in this thesis have logical strictness and accuracy.Through system debugging and experiment,it shows that the logical algorithm for the design of HD multi-view 3D pixel reconfiguration is feasible,which meets the pixel reconfiguration requirements of multi-view and multi sub screen partition,and can provide useful reference for the IC Design of multi-view video processing.
