Dual Pixel 简介

双像素是成像系统的感光元器件中单帧同时生成的图像：通过双像素可以实现：深度估计、图像去模糊去雨去雾恢复、图像重建

成像原理来源如上，也有遮罩等方式的pd生成，如图双像素视图可以看到光圈的不同一半，这提供了一个深度提示。然而，由于基本的模糊性，如果相机的焦距（或光圈大小或焦距）发生变化，不同的场景可能会产生相同的双像素图像。在（a）中，具有焦距g1的相机在距离Z1处成像聚焦的蓝色点和离焦的橙色点。通过光圈左半部分折射的光（深蓝色和橙色光线）到达每个双像素的右半部分，反之亦然。这导致了一个双像素图像，其中失焦橙色点被d像素（a，“DP数据”）位移，被b像素模糊（a，”图像”）。在（b）中，不同的焦距和场景深度集产生相同的双像素和RGB图像。然而，如文中所示，该场景通过逆深度上的仿射变换与（a）中的场景相关。消费者迅速采用。双像素相机似乎代表了更雄心勃勃的光场相机和传统相机之间的一种有前景的折衷方案——DP相机牺牲了可忽略的空间分辨率来采样光场中的两个角度，而真正的单眼相机只采样一个角度，Lytro Illum等光场相机以牺牲显著的空间分辨率为代价采样196个角度。因此，它们在消费类相机和内窥镜等空间受限的应用中得到了更广泛的采用[6]。

消费类硬件的最新发展可能为深度估计的新方法提供机会。最近，通过使用密集的双像素（DP）传感器（图2），可以使用一台相机同时捕获两张类似于具有微小基线的立体对的图像（图1）。虽然这项技术最初是为相机自动对焦而开发的，但双像素图像也可以用来从单个相机中恢复密集的深度图，从而消除了对额外硬件、校准或同步的任何需求。例如，Wadhwa等人[55]使用经典的立体技术（块匹配和边缘感知平滑）从DP数据中恢复深度。但如图1所示，传统立体技术可以生成的深度图的质量是有限的，因为DP图像中视差和焦点之间的相互作用可能会导致经典立体匹配技术失败。现有的基于单眼学习的技术在这方面也表现不佳
