摘要
设计了一种基于全息光学元件的透视增强现实集成成像3D显示系统。对基于反射体全息原理的全息光学元件的记录及再现做了理论分析,并通过搭建实验光路记录一块尺寸为20 mm×20 mm的全息光学元件。该全息光学元件仅对满足布拉格条件的光线体现出微透镜阵列成像功能,再现出虚拟的3D图像,而真实3D物体发出的光线可以直接透过全息光学元件,因此该全息光学元件作为图像融合元件实现了真实3D物体与虚拟3D图像的融合。该实验研制的透视增强现实3D显示系统能够再现出较好的虚拟3D图像,有效地融合虚拟3D图像和真实3D物体,实现增强现实的3D显示效果。
Abstract
An augmented reality integral imaging three-dimensional (3D) display system based on holographic optical element is designed. Theoretical analysis is carried out on the record and reproduction of holographic optical element based on reflection volume holographic principle, and a holographic optical element with size of 20 mm×20 mm is recorded by setting up the experimental light path. The holographic optical element reflects the micro-lens array imaging function only for light which meets Bragg conditions, and it reproduces the virtual 3D image. The light emitted from the real 3D object can directly go through the holographic optical element. Therefore, the holographic optical element is used as an image fusion element to realize the fusion of the real 3D object and virtual 3D image. The developed optical see-through augmented reality 3D display system reproduces a better virtual 3D image and realizes the effective fusion with the real 3D object, which achieves the augmented reality 3D display effect.
