Example Embodiment
[0037] Example 1 Judgment of Western Red Flowers and Its Pseudo Parts
[0038] First, establish the identification model of Western Red Flowers and their fake goods
[0039] (1) Take known Western Red Flowers, safflower, corn, lotus, chrysanthemum, and pulp samples, PV500R-I portable near-infrared gauges for mobile phones, collect near-infrared spectroscopy data, total Acquisition 6 times;
[0040] (2) For each sample spectrum data for step (1), the average spectrum is used to divide each sample into training samples and predictive samples with the Kennard-Stone algorithm;
[0041] (3) Establish a western red flower hoes differential model based on partial least squares discriminant analysis (PLS-DA) by training sample;
[0042] (4) Take the predictive sample verification model;
[0043] Second, identify the sample to be tested
[0044] (5) Retrieving the sample, PV500R-I portable near-infrared gauges controlled by mobile mobile phone, collecting near-infrared spectroscopy data of...
