This paper presents a general plenoptic image formation model based on light ray radiometry. Most existing plenoptic image formation models focus on projection geometry inside a camera equipped with a specific optical device, such as an array of micro-thin-lenses, while light ray radiometry is incomplete or simply neglected. This study aims to describe a general view of light ray radiometry that is then used to define a plenoptic image formation model. This model is based on a radiometry model and light ray projection geometry; hence, it explains phenomena, such as light transport and light direction. Moreover, the proposed plenoptic image formation model describes several radiometric phenomena, such as haze, defocus blur or natural vignetting. The genericity of this model is shown by retrieving existing non-plenoptic models from it. Moreover, the proposed model is assessed by simulating various phenomena, including vignetting and defocus blur, from both synthetic and real data.

全光成像的辐射模型

本文提出了一种基于光线辐射测量的通用全光成像模型。大多数现有的全光成像模型专注于配备特定光学设备（例如微薄透镜阵列）的相机内的投影几何，而光线辐射测量不完整或被简单地忽略。本研究旨在描述光线辐射测量的一般视图，然后用于定义全光成像模型。该模型基于辐射测量模型和光线投影几何；因此，它解释了光传输和光方向等现象。此外，所提出的全光图像形成模型描述了几种辐射现象，例如雾霾、散焦模糊或自然渐晕。通过从中检索现有的非全光模型来显示该模型的通用性。而且，
