Research On Integrated Imaging 3D Display Based On Visual Perception

Integrated imaging technology is a classic naked-eye three-dimensional(3D)light field imaging technology.In recent decades,with the advancement of high-resolution display devices and the emergence of high-quality,low-cost and effective microlens array manufacturing technology,re-recovery And achieved rapid development.Integrated imaging can be used to display three-dimensional images with full parallax and continuous viewpoints,and no auxiliary viewing devices and coherent light sources are required during display.Therefore,integrated imaging technology is considered to be a promising imaging technology.Imaging technology is an important technology for visually and intuitively presenting information,and it plays an extremely important role in information science and technology.Modern display technology is dedicated to a more realistic re-emergence of the objective world,where understanding of human vision is critical to this technology,as the ultimate goal is to provide the emotional experience that the observer needs.The human visual system is a highly evolved system that does not currently have any sensors comparable.Human visual perception can not only perceive the color information of the objective world,but also perceive the depth information of the objective world,that is,3D spatial information.If modern display technology is to achieve a more realistic re-emergence of the objective world,it must be based on a deeper understanding of visual perception,so that the display device can better visualize the viewer while reconstructing the information more realistically.Adaptability and comfort.This thesis focuses on the research of integrated imaging technology based on visual perception.This paper explores this technology from an important perspective.By analyzing human visual perception models,especially 3D display,combined with the main parameters of integrated imaging 3D display technology,the integration is analyzed.The 3D visual mechanism and display effect of the 3D display are imaged in order to provide a better visual experience for the viewer.The work content and innovations of this paper are as follows:(1)Constructing an integrated imaging system consisting of 34×19 diameter 9mm lenses and 4K high resolution display and diffusion screen;constructing a practical experimental platform for 3D display research.Further,based on the theory of light field imaging,the main parameters of the system are described.The light field parameterization method is used to establish the corresponding light field model,and the parameters and coding methods of the system are given.(2)Using the characteristics of the parameter representation of the wide field of view(high-angle resolution)of the system,the relationship between visual perception and display angular resolution is studied.In the multi-view acquisition stage of programming,3ds MAX software is used to simulate 3D scenes and cameras.Any optical field encoded by the acquired discrete view is obtained by matlab;the meta image is obtained;in the optical reconstruction stage,the encoded meta image is sent to the constructed The system serves as an experimental device.The relationship between angular resolution and the number of meta-images and the related constraints of parameters between the entire lens array system are analyzed from the perspective of human perception.At the same time,innovative use of Windows batch command acquisition view in programming saves manpower and time in the acquisition phase.(3)According to the characteristics of integrated imaging technology,the depth reconstruction ability of the system is further studied,and it is related to human depth perception,and its relationship with angular resolution and spatial resolution is discussed.Limitations and ideas for further improvement.
