多变量校正模型在光谱技术的测量系统中至关重要,为了构建一个稳健的校正模型,往往需要花费大量人力和财力。然而,当采集样品光谱的仪器不同于建立校正模型的仪器或由于环境因素的影响原仪器已经发生变化时,模型将失效。因此,本文创造一种基于小波变换的校正转移(标准化)法,用于两台近红外光谱仪之间的光谱转移,转移性能比分段直接标准化方法更好。 Multivariate calibration models are crucial in spectroscopic measurement systems, and often require significant human and financial costs to build a robust calibration model. However, the model will fail when the instrument that acquired the spectrum of the sample differs from the instrument that established the calibration model or the original instrument has changed due to environmental factors. Therefore, this paper presents a method based on wavelet transform (standardization) for the spectral shift between two NIRS instruments. The transfer performance is better than the direct normalization method.
