Multispectral wood analysis dataset: X-ray, Terahertz, and visible light imaging

Dataset Description: Non-Destructive Wood Analysis This dataset provides a comprehensive exploration of wood properties through three distinct measurement methods: X-ray imaging, terahertz waves, and visible light imaging. The dataset encompasses a diverse range of wood samples, including 38 different species of softwoods, hardwoods, and tropical species sourced from regions such as Europe, Asia, North America and Africa. Data Generation and Processing: X-ray imaging was conducted using an industrial optical scanner equipped with a transmission X-ray imaging system. Terahertz measurements utilized a Frequency Modulated Continuous Wave radar with a frequency range between 110 GHz and 130 GHz. Additionally, all samples were photographed on all six faces using a standard printer scanner. Data File Details: The dataset is packaged in a compressed folder, "THz_XR_RGB_Wood_Dataset.zip," containing four subfolders for each measurement type: THz, X-ray, RGB and Specifications. The THz and X-ray subfolders include separate files for diverse and tropical wood samples, while the Specifications subfolders contain CSV files with sample details (dimensions and mass). The RGB subfolder houses color images of all faces of each sample. This dataset serves as a valuable resource for researchers exploring non-destructive imaging technologies, offering insights into the intricacies of wood structure and properties through varied measurement techniques.

数据集说明：无损木材分析
本数据集通过三种差异化测量方法——X射线成像、太赫兹波（terahertz waves）成像与可见光成像——对木材性能展开全面探究。数据集涵盖多样化木材样本，包含来自欧洲、亚洲、北美及非洲等地区的38种软木、硬木与热带木材品种。

数据生成与处理流程：
X射线成像采用搭载透射式X射线成像系统的工业光学扫描仪完成；太赫兹测量采用频率范围为110 GHz至130 GHz的调频连续波（Frequency Modulated Continuous Wave）雷达进行；此外，使用标准打印扫描仪对所有样本的六个表面完成拍摄。

数据文件详情：
本数据集打包为压缩文件夹"THz_XR_RGB_Wood_Dataset.zip"，内含对应四种测量类型的四个子文件夹：太赫兹（THz）、X射线（X-ray）、RGB与参数说明（Specifications）。太赫兹与X射线子文件夹中包含针对通用木材样本与热带木材样本的独立文件；参数说明子文件夹内含存储样本详细信息（尺寸与质量）的CSV文件；RGB子文件夹中存储了每个样本所有表面的彩色图像。

本数据集可为研究无损成像技术的科研人员提供宝贵资源，通过多样化的测量技术助力研究者深入解析木材结构与性能的复杂特性。
