Embodiment Construction
[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited to the content described.
[0019] Quantitative modeling method of near-infrared spectrum of tobacco leaves based on deep learning, such as figure 1 shown, including the following steps:
[0020] ① Obtain the near-infrared spectral information of tobacco leaves, and perform preprocessing operations on the spectral data. In this embodiment, the existing near-infrared spectrometer is used to collect spectral information, and the collection range is between 1000 nm and 2500 nm wavelength or any part thereof. The preprocessing of spectral information includes eliminating baseline drift and removing spectral noise; spectral information preprocessing methods include wavelet transform algorithm, SG convolution smoothing method, multivariate scattering correction method, first-or...
