真三维成像系统结构设计及GR空间模型分析

本文提出了一种基于下投影的真三维立体成像显示系统。讨论了一种基于空间和时间的三维模型体素构造的新方法——体素铸模法,并推导了四维局部状态空间模型Givone-Roessor,此模型利用状态矢量和输入矢量计算和表征体素变量,模型在某时刻计算的各变量只与相邻的体素或前一时刻有关,减少了计算量。系统机械结构简单轻便,成本低,功耗小;视场角大,除天顶点外,在整个x-y平面以上的半球空间均可成立体像;Givone-Roessor模型计算量小,便于微控制器实现,为真三维立体成像显示提供了一种新方法。

Design of True 3D Imaging Display System Structure and Analysis of GR Local State-space Model

In this paper,a true three-dimensional imaging display system based on projection is presented. A new light emitting structure method of volume pixels（voxel） based on Space and time is discussed, and the 4D local state-space model-Givone-Roessor is derived to compute and feature the voxel variables by using the state vector and input vector. Each variable calculation of this model in a certain time is only related to the adjacent voxel or the adjacent time,and the amount of computation is reduced significantly. The mechanical structure is simple and the cost is inexpensive;the field angle is so larger and almost half a sphere except the zenith point can be displayed;and the voxels constructor is easy to implement by micro controller due to the small amount of GR model.
