We have developed a compact integral three-dimensional (3D) imaging equipment that positions the lens array and image sensor in close proximity to each other. In the conventional scheme, a camera lens is used to project the elemental images generated by the lens array onto the image sensor. In contrast, the imaging equipment presented here combines the lens array and image sensor into one unit and makes no use of a camera lens. This scheme eliminates the resolution deterioration and distortion caused by the use of a camera lens and improves, in principle, the quality of the reconstructed 3D image. We captured objects with this imaging equipment and displayed the reconstructed 3D images using display equipment consisting of a liquid crystal panel and a lens array. The reconstructed 3D images were found to have appropriate motion parallax.
我们开发了一种紧凑的集成三维（3D）成像设备，该设备将透镜阵列和图像传感器紧密地放置在一起。在传统方案中，使用相机镜头将透镜阵列产生的元图像投影到图像传感器上。相比之下，这里介绍的成像设备将透镜阵列和图像传感器集成在一起，而不使用相机镜头。该方案消除了使用相机镜头引起的分辨率下降和失真，并在原理上提高了重建的 3D 图像的质量。我们使用该成像设备拍摄物体，并使用由液晶面板和透镜阵列组成的显示设备显示重建的 3D 图像。重建的 3D 图像具有适当的运动视差。
