Model migration method and system based on elastic segmentation standardization algorithm

The invention provides a model migration method and system based on an elastic segmentation standardization algorithm, and relates to the field of spectral analysis, and the method comprises the steps: firstly obtaining spectral data collected by a host and a satellite machine, taking the spectral data as a sample, and determining the wavelength range of the spectral data; carrying out full spectrum analysis and normalization operation on the spectral data; dividing each fold of spectral data into a training data set and a verification data set; establishing a quantitative analysis model by using host spectral data; setting the initial width of the window; training a multiple regression model; recording a satellite machine spectral line and a host spectral line after verification set correction; selecting an optimal window width according to the RMSE of the verification set to establish a conversion matrix; converting the satellite machine spectrum data through a conversion matrix; and taking the converted sa
