Embodiment
[0032] The objects of collection are the seeds of three kinds of Sorghum genus Sorghum, Sorghum pseudosorghum and Sudangrass. This detection method is also applicable to other seeds of the Sorghum genus.
[0033] The spectral data is collected in the range of 325-1075nm, the spectral sampling interval is 1.5nm, the number of scans is 30 times, and the field of view of the probe is 20 degrees. The light source is a 14.5V halogen lamp matched with the spectrometer.
[0034] A total of 120 samples (40 for each variety) were collected from three species of Sorghum. Various samples are all packed in petri dishes with a diameter of 40-50mm and a height of 8-10mm. In order to reduce the experimental error and ensure that the measured object is equidistant from the instrument, each petri dish is filled as an experimental sample. 40 samples were made for each variety, a total of 120 samples. All experimental samples were randomly divided into a modeling set and a prediction set. Th...
