Embodiment Construction
[0034] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0035] figure 1 It is a flow chart of an imaging spectrometer-based identification method for sulfur fumigation of traditional Chinese medicines according to an embodiment of the present invention; refer to figure 1 , the method includes:
[0036] S1: Obtain a hyperspectral image of the traditional Chinese medicine to be identified in a preset band, and calculate the spectral index feature of the traditional Chinese medicine to be identified according to the hyperspectral image of the traditional Chinese medicine to be identified in a preset band;
[0037] S2: Classify the Chinese medicine to be identified according to the hyperspectral image of the traditional Chinese m...

The invention discloses a sulfur fumigated traditional Chinese medicine discriminating method and a system thereof based on an imaging spectrometer, and relates to the technical field of remote sensing. The method comprises the steps that S1: a hyperspectral image of a traditional Chinese medicine to be discriminated within the preset wave band is acquired, and the spectral index characteristics of the traditional Chinese medicine to be discriminated are calculated according to the hyperspectral image of the traditional Chinese medicine to be discriminated within the preset wave band; S2: and the traditional Chinese medicine to be discriminated is classified according to the hyperspectral image of the traditional Chinese medicine to be discriminated within the preset wave band and the spectral index characteristics of the traditional Chinese medicine to be discriminated so that whether the traditional Chinese medicine to be discriminated is fumigated by sulfur can be confirmed. The traditional Chinese medicine to be discriminated is classified through the hyperspectral image of the traditional Chinese medicine to be discriminated within the preset wave band and the spectral index characteristics of the traditional Chinese medicine to be discriminated so that discriminating precision and efficiency are enhanced.
Description
technical field [0001] The invention relates to the technical field of remote sensing, in particular to a method and system for identifying sulfur fumigation of traditional Chinese medicine based on an imaging spectrometer. Background technique [0002] Sulfur smoked Chinese herbal medicines used to be a traditional method of processing medicinal materials in my country. It was mainly used to prevent insects and moisture, facilitate the storage of medicinal materials, reduce the loss of medicinal materials, and increase the color. However, because sulfur dioxide will be produced after burning sulfur, it is very easy to remain in the medicinal materials. Long-term use will damage the digestive tract and respiratory tract, as well as liver, kidney and other organs. Therefore, the State Food and Drug Administration issued a special document in 2004, prohibiting the use of sulfur to smoke Chinese herbal medicines. [0003] At present, this method is still used illegally by many...
