In multi-view three-dimensional imaging, to capture the elemental images of distant objects, the use of a field-like lens that projects the reference plane onto the microlens array is necessary. In this case, the spatial resolution of reconstructed images is equal to the spatial density of microlenses in the array. In this paper we report a simple method, based on the realization of double snapshots, to double the 2D pixel density of reconstructed scenes. Experiments are reported to support the proposed approach.
在多视图三维成像中，为了捕获远处物体的基本图像，需要使用一种场透镜将参考平面投影到微透镜阵列上。在这种情况下，重建图像的空间分辨率等于阵列中微透镜的空间密度。在本文中，我们报告了一种基于实现双快照的简单方法，以将重建场景的二维像素密度提高一倍。报告了实验以支持所提出的方法。
