In this study, the results from a round-robin test of hyperspectral imaging systems are presented and analyzed. Fourteen different pushbroom hyperspectral systems from eight different institutions were used to acquire spectral cubes from the visible, near infra-red and short-wave infra-red regions. Each system was used to acquire a common set of targets under their normal operating conditions with the data calibrated and processed using the standard processing pipeline for each system. The test targets consisted of a spectral wavelength standard and of a custom-made pigment panel featuring Renaissance-era pigments frequently found in paintings from that period. The quality and accuracy of the resulting data was assessed with quantitative analyses of the spectral, spatial and colorimetric accuracy of the data. The results provide a valuable insight into the accuracy, reproducibility and precision of hyperspectral imaging equipment when used under routine operating conditions. The distribution and type of error found within the data can provide useful information on the fundamental and practical limits of such equipment when used for applications such as spectral classification, change detection, colorimetry and others.

通过高光谱成像系统的循环测试评估数据质量。

在这项研究中，提出并分析了高光谱成像系统的循环测试结果。来自八个不同机构的十四个不同的推扫式高光谱系统用于从可见光，近红外和短波红外区域获取光谱立方。每个系统用于在其正常操作条件下获取一组通用目标，并使用每个系统的标准处理管道对数据进行校准和处理。测试目标包括一个光谱波长标准和一个定制的颜料面板，该面板具有那段时期在绘画中经常发现的文艺复兴时期颜料。通过对数据的光谱，空间和比色法准确性进行定量分析，评估了所得数据的质量和准确性。这些结果为在常规操作条件下使用时高光谱成像设备的准确性，可重复性和精度提供了宝贵的见解。当用于光谱分类，变化检测，比色法等应用时，数据中发现的错误的分布和类型可以提供有关此类设备的基本和实际限制的有用信息。
