Research On Multi-view Naked-eye 3D Pixel Reconfiguration Technology

The multi-view naked-eye 3D technology has the matching of the viewing angle of the three-dimensional scene,and is an extension and extension of the naked-eye 3D technology.The basic theory of naked-eye 3D technology has matured and began to transform into products and gradually form industrial value.In this paper,the stereoscopic test and position calibration of the naked eye 3D LCD screen are taken as the experimental basis,and the technical method of multi-angle video pixel reconfiguration of multi-view naked eye 3D technology is discussed.The research work completed in this paper is as follows:(1)Based on the previous three-dimensional test pattern FPGA method developed by the research group,the naked-eye 3D LCD screen independent view area stereo test and position calibration experiment system were developed to meet the test requirements.Taking AUO's 8-inch open-hole 3D LCD screen as the experimental object,the FPGA pattern generation system is used to access the data interface of the LCD screen,and the test patterns of the left and right sub-screens are displayed on the screen.The pattern is in monochrome mode and its color value is set to 255.The position of the camera is positioned by the guide rail,and the screen image is intensively captured in the 3D screen viewing area,and the stereoscopic value of each coordinate point is obtained by the later image processing method.From the spatial coordinate position and the corresponding stereoscopic value,the independent viewport position of the naked-eye 3D LCD screen is accurately calibrated.(2)According to the calibration results of the independent viewport of the naked-eye 3D LCD screen,it can be seen that the spatial distribution characteristics of the independent viewport meet the requirements of the automatic multi-view technology.Therefore,the principle and method of FPGA pixel reconfiguration technology for multi-view video are studied.Multi-view naked-eye 3D is a system with multiple 3D video source inputs that can be used to swap video images on the left and right eye sub-screens in real time based on the correspondence of the eye to the independent viewport position.In this paper,the theoretical basis and implementation method of multi-viewpoint are discussed in detail,and the technical architecture of 3D video pixel reconfiguration method based on LVDS protocol for LCD input port is studied.Multi-group logic module is built by FPGA,and the research of multi-view pixel reconfiguration is preliminarily completed.The main innovations of the thesis are: the systematic method of positioning the independent view zone and the technical method of multi-view pixel reconfiguration.The research results show that the location calibration of the independent view zone is a necessary part of the research and application of the naked eye 3D technology productization,and the correctness of the independent view zone theory is also proved experimentally.Multi-view pixel reconfiguration technology research provides a way of thinking for the continuous development of naked-eye 3D technology,which is helpful for industry reference and implementation.
