Study of translational motion swept-volume techniques in true 3D volumetric display systems

随着计算机技术的快速发展,真三维立体显示技术作为一种全新的三维图像显示技术,它将引领科学可视化进入崭新的发展方向,具有广阔的应用前景。对其中的平移体扫描显示系统的成像原理,运动方式进行了研究。详细研究了按正弦曲线运动的平移体扫描显示系统,用线性近似的方法得到均匀的图像,并分析了由于线性近似带来的最大屏幕位置误差,这种显示系统可以较好地实现真三维显示。

With the rapid development of computer technology, as a completely new 3D image display technique, True 3D volumetric display techniques will lead science visualization to a new development direction and have a wide area of applications in the future. Imaging theory and motional types of swept-volume display systems of translational motion were studied. Particularly, a display unit in which screen moved with a sinusoidal velocity profile was studied. By using linear approximation, the homogeneous was graphic obtained and worst-case positional error due to linear approximation was analyzed in the system, The system could realize true 3D effect.
