| Light field display technology is the new trend of the development of the current free-form display technology.The long production time of 3D display content and the slow generation of integrated imaging hinders the development and application of light field technology.In response to this problem,this paper uses computer generated integrated imaging method.Using the ray tracing algorithm to sample the virtual scene,the pixel is encoded to obtain the 3D light field map,which improves the rendering speed.The main contents of this thesis and the main innovations obtained are summarized as follows:1 Using ray tracing engine,a real-time content generation system suitable for light field display is built.The system can be compatible with the common three-dimensional model data,and uses CUDA-based surface area heuristic hierarchical bounding box acceleration structure to render simple three-dimensional scene in real time.Through the mouse,keyboard and other equipment,three-dimensional images can be interactive.2 We proposed a three-dimensional image correction scheme by real-time modification of virtual camera parameters.Through the control of the camera's direction,position and angle of view in the ray tracing engine,the problem of the display fuzzy and fault caused during the interaction was solved.3 The relationship between the virtual object and the depth of field of the 3D display is obtained through experiments.Based on this,the depth of field is used to limit the position and size of the virtual object so that the object can be clearly and correctly displayed.The research results have enriched the theory of computer-generated multi-view images in light field display and provided a technical solution for the application of real-time interactive light field display system.The correction algorithm in this paper provides a theoretical basis in the field of 3D display and interaction and provides a solution for the pixel correction in the future interaction. |
