A dual-view display system provides two different images in different directions. Most of them only present two-dimensional images for observers. In this paper, we propose a projection-type dual-view three-dimensional (3D) display system based on integral imaging. To assign directivities to the images, a projection-type display and dual-view screen with lenticular lenses are implemented. The lenticular lenses split the collimated image from the projection device into two different directions. The separated images are integrated by a single lens array in front of the screen, and full-parallax 3D images are observed in two different viewing regions. The visibility of the reconstructed 3D images can be improved by using high-density lenticular lenses and a high numerical aperture lens array. We explain the principle of the proposed method and verify the feasibility of the proposed system with simulations and experimental results.
一种双视图显示系统在不同方向上提供两种不同的图像。它们中的大多数只为观察者呈现二维图像。在本文中，我们提出了一种基于积分成像的投影型双视图三维（3D）显示系统。为了给图像赋予方向性，实现了一种带有柱面透镜的投影型显示器和双视图屏幕。柱面透镜将来自投影设备的准直图像分成两个不同的方向。分离后的图像由屏幕前方的单个透镜阵列进行整合，并且在两个不同的观看区域中可以观察到全视差3D图像。通过使用高密度柱面透镜和高数值孔径透镜阵列，可以提高重建3D图像的可视性。我们解释了所提方法的原理，并通过仿真和实验结果验证了所提系统的可行性。
