We present a method for recovering the perspective image of a non-line-of-sight scene based on plenoptic observations of indirect photons scattered from a flat homogeneous surface. The plenoptic information is used to ascertain locations of non-line-of-sight features in a hidden scene. This latent knowledge is then used for the partial reconstruction of the scene by extracting the imagery perceived by the non-line-of-sight features from the scattered light field measured along the surface. We demonstrate the efficacy of our technique by applying it to synthetic and measured light field data to retrieve the locations of multiple knife-edge occlusions in a test scene along with their perceived imagery.

在被动全光成像中定位非视线特征并恢复通过视差传送的图像

我们提出了一种基于对从平坦均匀表面散射的间接光子的全光观察来恢复非视线场景的透视图像的方法。全光信息用于确定隐藏场景中非视线特征的位置。然后，通过从沿表面测量的散射光场中提取非视线特征感知的图像，将此潜在知识用于场景的部分重建。我们通过将其应用于合成和测量的光场数据以检索测试场景中多个刀口遮挡的位置及其感知图像来证明我们的技术的功效。
