In this study, a novel gonio-hyperspectral imaging system based on light-emitting diodes for the analysis of automotive coatings was validated colorimetrically and spectrally from 368 to 1309 nm. A total of 30 pearlescent, 30 metallic, and 30 solid real automotive coatings were evaluated with this system, the BYK-mac and X-Rite MA98 gonio-spectrophotometers, and also with the SPECTRO 320 spectrometer for further comparison. The results showed very precise correlations, especially in the visible range. In conclusion, this new system provides a deeper assessment of goniochromatic pigments than current approaches due to the expansion of the spectral range to the infrared.
在本研究中，一种基于发光二极管的新型多角度高光谱成像系统被用于汽车涂料分析，并在368至1309纳米范围内进行了比色和光谱验证。该系统对30种珠光、30种金属和30种纯色真实汽车涂料进行了评估，同时还使用了BYK-mac和爱色丽MA98多角度分光光度计，以及SPECTRO 320光谱仪进行进一步比较。结果显示出非常精确的相关性，尤其是在可见光范围内。总之，由于光谱范围扩展到了红外区域，该新系统比目前的方法能更深入地评估变色颜料。
