Lightfield Three-dimensional Display System Based On Scanning LED

As an important development direction of future display technology, three-dimensional display technology has always attracted the attention of researchers around the world. With the development of the hardware and technical level, the effect and scale of three-dimensional display have been significantly improved, a variety of new display devices have been invented. The principle three-dimensional display based on light field reconstruction has been proposed, to construct three-dimensional device from the perspective of the light field reconstruction has become the latest research direction. The omnidirectional-view three-dimensional display is an important branch of the light field reconstruction systems, it is a glass-free, omnidirectional-view, observer-unrestricted and has many other advantages, it is a advanced display technology more suitable to restore the real space object.In this paper, a comprehensive analysis of the light-field three-dimensional display system based on scanning LED is made. And then make a detailed analysis of the system parameters as image resolution, refresh rate and image distortion of the system. Further analysis of the relationship between its three-dimensional display parameters and structure parameters is made. All of these provide a good theoretical basis for the implementation of the system.On the basis of the above analysis, we study the implementation method of the system. First of all. presents a view-based light field generation method, then implement it base on C language. This approach would combine the height of observer's point of view and the perspective view to in consider and provides accurate perspective relationship. Proposed acceleration method based on the look-up table method which greatly improved the generation efficienc. Elaborate the design of the circuit and the mechanical structure of the system, and successfully built the entire system. Finally, design the display system error compensation processes, and successful implement it.It could be found that there is still the space for system to improve the effect of display. In order to improve the display effect of the system, and also in order to lay a foundation for follow-up system design, a simulation program based on OpenGL and light field reconstruction principle is designed. Two simulation principle were applied on different occasions. Based on the analysis of the system structure, contradiction between the data capacity and the two-dimensional resolution is pointed out, and an optimization method is proposed. Then the simulation program is used to verify the results of optimization.
