Camera Spectral Sensitivity Database - Jiang et al. (2013)

Source URL: http://www.gujinwei.org/research/camspec/db.html Source DOI: 10.1109/WACV.2013.6475015 Camera spectral sensitivity functions relate scene radiance with captured RGB triplets. They are important for many computer vision tasks that use color information, such as multispectral imaging, and color constancy. We create a database of 28 cameras covering a variety of types. The database contains the spectral sensitivity functions for 28 cameras, including professional DSLRs, point-and-shoot, industrial and mobile phone camera. We use a spectrometer PR655 from Photo Research Inc., a light source and monochrometer combined with an integrating sphere to do the measurement. Each measurement starts from wavelength 400nm to 720nm in an interval of 10nm. Measured Sensitivities are normalized to 1 for RGB channels seperately. The database is in the form of a text file. Each entry starts with camera name and follows by measured spectral sensitivities in red, green and blue channel.

相机光谱灵敏度函数（Camera spectral sensitivity functions）可建立场景辐射度与捕获的RGB三元组之间的关联，其在诸多依赖色彩信息的计算机视觉任务中至关重要，例如多光谱成像、颜色恒常性等。
我们构建了涵盖28款不同类型相机的数据库。该数据库收录了28款相机的光谱灵敏度函数，覆盖专业数码单反相机、便携消费级相机、工业相机以及手机相机。
本次测量采用Photo Research公司生产的PR655光谱仪（spectrometer），搭配光源、单色仪（monochrometer）与积分球（integrating sphere）完成实验。
所有测量的波长覆盖范围为400nm至720nm，采样步长为10nm。测得的各RGB通道灵敏度均分别归一化至1。
该数据库以文本文件格式存储，每条记录以相机名称作为起始标识，随后依次给出红、绿、蓝三个通道的实测光谱灵敏度数据。
