Hyperspectral Imaging dataset for use in Heritage Science

The following data sets were collected to support the potential uses of opensource data in the context of digital humanities and heritage sciences. This proposed experiment is conducted by the UCL Institute for Sustainable Heritage in collaboration with the Centre for Digital Humanities. Imaging methods including Photography, Multispectral Imaging, Hyperspectral Imaging and Xray Fluorescence Mapping have been collected along with the complete readout metadata of the instrumentation. We hope that you find the data helpful, and we welcome you to use the data in any way you wish, for all and any analysis development purposes. For us to build upon this research, we ask that in return you would be willing to share in some regard your experiences in using open-source data, using our data, successes and issues. If you would be willing to engage with us in this endeavor, please feel free to contact us so that we may be able to follow up with you. E: [e-mail] Object Paradata; <strong>Postcard – c. Early 1900's </strong> <strong>Language – Eng. </strong> <strong>Materials – colour print on card, metallic leafing. </strong> <strong>Front transcription - </strong> <strong> ‘Greetings’ </strong> <strong> ‘May your Birthday bring you Peace &amp; perfect Happiness, Golden hopes &amp; Love of Friends, And every Happiness this world can send.’ </strong> <strong>Object Dimensions – 138mm X 88mm </strong> This folder contains: Hyperspectral Image data collected using a ClydeHSI VNIR-HR+ Hyperspectral Imaging System. postcardhsi.hdr - Header file read out from the ClydeHSI systems instructions for reading the subsequent .raw spectral database. postcardhsi.raw - Hyperspectral image data cube information. Combination with hdr file creates a ENVI file format, this can be read into a variety of image analysis software packages. postcardhsi.ini - Metadata collected and read out from ClydeHSI system. Dark/White.corr - Correction files taken from camera for processing and minimalising system noise and illumination variences. postcardhsi_refl.* - Pre - Corrected hyperspectral image data, using provided ClydeHSI software. Truecolour RGB reference image Each raw and header file set makes-up a single data set in ENVI file format. ENVI reading support exists in Python, R, Matlab, and other common image analysis packages.本数据集的采集工作旨在支撑开源数据在数字人文与遗产科学场景下的潜在应用。本探究性实验由伦敦大学学院（UCL）可持续遗产研究所（Institute for Sustainable Heritage）与数字人文中心（Centre for Digital Humanities）联合开展。采集的成像手段涵盖摄影、多光谱成像（Multispectral Imaging）、高光谱成像（Hyperspectral Imaging）以及X射线荧光映射（Xray Fluorescence Mapping），并附带仪器设备的完整读出元数据（metadata）。 我们诚挚希望本数据集可为您的研究提供助力，欢迎您将其用于任意分析开发相关的用途。为推动本研究的后续迭代，我们恳请您在使用开源数据、本数据集的过程中，将您的使用体验、取得的成果以及遇到的问题以适当形式与我们分享。若您愿意参与此项协作，请随时联系我们，以便我们跟进沟通。联系方式：[e-mail] <strong>物品元数据</strong>： <strong>明信片——约20世纪早期</strong> <strong>语言——英语</strong> <strong>材质——卡纸彩色印刷、金属烫金</strong> <strong>正面转录文本——</strong> <strong>‘致意’</strong> <strong>‘愿你的生日带来安宁与完满幸福，黄金般的期许与挚友的爱意，以及世间所能赐予的一切美好。’</strong> <strong>物品尺寸——138mm×88mm</strong> 本文件夹包含以下内容： 采用ClydeHSI VNIR-HR+高光谱成像系统采集的高光谱图像数据： - postcardhsi.hdr：从ClydeHSI系统导出的头文件，用于读取后续的.raw光谱数据库； - postcardhsi.raw：高光谱图像数据立方体信息； 上述头文件与.raw文件组合后可生成ENVI格式（ENVI file format）文件，可通过多款图像分析软件读取。 - postcardhsi.ini：从ClydeHSI系统采集并导出的元数据； - Dark/White.corr：为抑制系统噪声、减小光照差异而采集的暗场/白场校正文件； - postcardhsi_refl.*：采用配套ClydeHSI软件完成预处理校正后的高光谱图像数据； - 真彩色RGB参考图像 每套头文件与.raw文件组合均可构成一套ENVI格式数据集。ENVI格式的读取支持Python、R、Matlab以及其他主流图像分析软件包。
