摘要： A plenoptic camera captures a plenoptic image of an object illuminated by a point source (preferably, collimated illumination). The plenoptic image is a sampling of the four-dimensional light field reflected from the object. The plenoptic image is made up of superpixels, each of which is made up of subpixels. Each superpixel captures light from a certain region of the object (i.e., a range of x,y spatial locations) and the subpixels within a superpixel capture light propagating within a certain range of directions (i.e., a range of u,v spatial directions). Accordingly, optical properties estimation, surface normal reconstruction, depth estimation, and three-dimensional rendering can be provided by processing only a single plenoptic image. In one approach, the plenoptic image is used to estimate the bidirectional reflectance distribution function (BRDF) of the object surface.

摘要翻译：全景照相机捕获由点光源照射的物体的全光图像（优选地，准直照明）。全光图像是从物体反射的四维光场的采样。全视觉图像由超像素组成，每个像素由子像素组成。每个超像素捕获来自对象的特定区域（即，x，y空间位置的范围）的光和在一定范围的方向（即，u，v空间方向的范围）内传播的超像素捕获光中的子像素，。因此，可以通过仅处理单个全视觉图像来提供光学性质估计，表面正常重建，深度估计和三维渲染。在一种方法中，全光图像用于估计物体表面的双向反射分布函数（BRDF）。

摘要： A collimated object is adjustable to produce collimated light propagating along different propagation directions. The plenoptic imaging system under calibration captures plenoptic images of the object adjusted to different propagation directions. The captured plenoptic images includes superpixels, each of which includes subpixels. Each subpixel captures light from a corresponding light field viewing direction. Based on the captured plenoptic images, a calibration module calculates which propagation directions map to which subpixels. The mapping defines the light field viewing directions for the subpixels. This can be used to improve processing of plenoptic images captured by the plenoptic imaging system.
