These methods are becoming increasingly important for the color processing pipeline in movie productions. Knowing the spectral power distribution of light sources used in a movie production is essential for a spectral based approach to ensure a correct color reproduction in movie data creation. We present a thoroughly documented data set of spectral power distributions of typical film and TV lighting. The data set can be used to create more precise camera characterizations and help to develop spectral color processing pipelines. Furthermore, the spectral power distribution data set can be employed to detect and validate over-aged or damaged lighting, by comparing their spectra to our reference measurement.<strong>来源链接</strong>: https://www.researchgate.net/publication/282908037_A_Spectral_Database_of_Commonly_Used_Cine_Lighting <strong>摘要</strong> 近年来，多项用于估算相机系统光谱响应或物体反射光谱的方法已被公开。此类方法在影视制作的色彩处理流程中重要性日益凸显。对于基于光谱的色彩还原方案而言，掌握影视制作中所用光源的光谱功率分布（spectral power distribution），是保障影视数据创作阶段色彩准确还原的核心前提。本研究发布了一套完备文档化的典型影视照明光谱功率分布数据集。该数据集可用于构建精度更高的相机光谱特性表征，并助力开发光谱色彩处理流程。此外，通过将待测照明设备的光谱与本数据集的参考测量结果进行比对，该光谱功率分布数据集还可用于检测并核验老化或损坏的照明装置。
