Abstract

We present a novel approach for image based relighting using the lighting controls available in a regular room. We employ individual light sources available in the room such as windows and house lights as basis lighting conditions. We further optimize the projection of a desired lighting environment into the sparse room lighting basis in order to closely approximate the target lighting environment with the given lighting basis. We achieve plausible relit results that compare favourably with ground truth relighting with dense sampling of the reflectance field.
基于图像的照明使用室内照明基础
我们提出了一种基于图像的重新照明的新方法,使用常规房间中可用的照明控制。我们使用房间内可用的单个光源,如窗户和室内灯作为基本照明条件。我们进一步优化了期望的照明环境投射到稀疏的房间照明基础上,以便与给定的照明基础紧密接近目标照明环境。我们获得了可信的再现结果,与反射场密集采样的地面真值再现相媲美。
