摘　　要：通过介绍真三维显示模型,解释了基于可视体素的显示技术.针对LED真三维显示分辨率较低的问题,采用光投影阵列的真三维显示方案,结合真三维显示固有的连续图像的特性,研究了真三维编解码算法,建立了基于光线追踪的几何校正模型.实验证明,该方法可构建实用的高分辨率真三维显示器,同时能够展示准确的物体.By introducing a true 3D display model, volumetric display technique based on visual voxel was explained. To solve the low-resolution problem of true 3D LED displayer, multi-ma- chine synchronization projection method was proposed. With serial section images of true 3D dis- play, the codec algorithm for true 3D display was studied and geometric correction model based on ray tracing method was built. The experiment proves that this method can build a practical and high-resolution true 3D displayer and can display the object exactly.
