Abstract

The invention discloses a quantitative analysis method based on infrared spectrum. The method comprises: acquiring a two-dimensional atlas of a sample to be detected, the two-dimensional atlas including an infrared spectrum atlas; converting the two-dimensional atlas into a three-dimensional atlas; The three-dimensional map is input into a preset quantitative model, and the content of the target component in the sample to be detected is output. The invention also discloses a quantitative analysis device based on infrared spectrum. By adopting the invention, the content of the target component in the sample to be detected can be accurately obtained.

Description

technical field [0001] The invention relates to the field of quantitative analysis, in particular to a quantitative analysis method, device, equipment and storage medium based on infrared spectroscopy. Background technique [0002] Near-infrared spectrometers have been applied to fields such as food analysis, drug analysis, and environmental testing due to their low cost, ease of use, and non-destructive testing. However, there are often overlapping signals in the near-infrared spectrum, and the spectrum contains not only the characteristic information of the target component but also the interference information. Therefore, in order to obtain the characteristic information of the target components from the raw maps, some chemometric methods need to be used. For example, in order to improve the quality of the established model, some preprocessing techniques are needed to reduce the interference of irrelevant information in the graph. Then, use such as partial least squares...
