1. a kind of wheat quality detection method based on Multi-information acquisition, it is characterised in that comprise the following steps:

  • Step one, using terahertz time-domain spectroscopic technology THz-TDS, analysis is gone mouldy, damages by worms, germinateing and normal wheat samplesIn the optics and spectral characteristic of 0.2~1.6THz wave bands, and calculate the absorption spectrum and refractive index spectra for obtaining wheat samples;

    Different quality wheat samples absorption spectrums and refractive index spectra are carried out spy by step 2 using PCA principal component analytical methodsExtraction is levied, characteristic value is ranked up according to size;

    Step 3, it is wheat samples absorption spectrum feature set to select preceding 8 principal component combinations of features, selects preceding 10 principal component spiesLevy and be combined as wheat quality refractive index spectra feature set;

    Step 4, modeling, and modeling result is verified.
