多视图3D液晶显示器显示深度计算

Depth measurement of multi-view 3D LCD

给出了针对多视图3D液晶显示器的虚体素明确的定义,对虚体素的特性做了说明。在深入掌握多视图3D液晶显示器显示原理的基础上,对虚体素显示深度做了详细的研究。研究了虚体素显示深度与同名点距离以及观察距离的关系,并以StereoGraphics公司的Symthagram204显示器为例作了定量计算。针对该显示器,根据透镜阵列折射原理给出公式,计算了不同同名点距离时最远的可观察距离;在此基础上,对不同的同名点距离计算了最大的虚体素显示深度,在给定两眼间距为65mm时,得出该型显示器的最佳观察距离为1.26m。研究结果为多视图3D液晶显示器性能的度量和比较提供了一个定量的标准。

We propose clear definition of virtual voxel about the multi-view 3D LCD and also specify its characteristics. With a thorough command of 3D LCD principles, the virtual voxel＇s display depth is carefully studied and its relation with corresponding point distance as well as observing distance is calculated quantitatively aim at the symthagram204 display of StereoGraphics company. Based on lens array refraction theory the formula is presented, with which the farthest observable distance between different corresponding points is calculated. It offers a foundation for the calculation of the most virtual voxel display depth between different corresponding points. If we set the interocular distance as 65mm, the optimum observing distance is calculated as 1.26m. The research provides a quantitative standard to measure and compares the performance of multi-view 3D LCD.
