Hyperspectral imaging system for monitoring agricultural products during processing and manufacturing
Provided is a method for monitoring a manufacturing process of an agricultural product. The method utilizes hyperspectral imaging and comprises scanning at least one region along a sample of agricultural product using at least one light source of a single or different wavelengths; generating hyperspectral images from the at least one region; determining a spectral fingerprint for the sample of agricultural product from the hyperspectral images; and comparing the spectral fingerprint so obtained to a spectral fingerprint database containing a plurality of fingerprints obtained at various points of the manufacturing process, using a computer processor, to determine which point in the manufacturing process the sample has progressed to.
1. A method for classifying a region of an agricultural product, the method utilizing hyperspectral imaging and comprising:
scanning a region along a sample of agricultural product using at least one light source of a single wavelength or different wavelengths;
generating one or more hyperspectral images from the region;
determining a spectral fingerprint for the sample of agricultural product from the one or more hyperspectral images; and
determining at least one property of the scanned region, the property including a physical property, a chemical property, a biological property, or any combination thereof;
assigning a classification code to the region of agricultural product based on the property; and
monitoring a progression of a processing or manufacturing process of the agricultural product using the classification code.
2. The method of claim 1 , further comprising:
scanning multiple regions along the sample of agricultural product using the at least one light source; and
generating hyperspectral images from the multiple regions.
3. The method of claim 1 , wherein the property includes a physical shape, a form, size dimensions, or any combination thereof.
4. The method of claim 1 , wherein the property includes a color.
5. The method of claim 1 , wherein the property includes a moisture content.
6. The method of claim 1 , wherein the property includes a chemical composition.
7. The method of claim 1 , wherein the property includes identification of foreign matter.
8. The method of claim 1 , wherein the property includes an activity or a reactivity of the sample to one or more physical stimulus.
9. The method of claim 8 , wherein said physical stimulus includes exposure to electromagnetic radiation.
10. The method of claim 1 , wherein the property includes an activity or a reactivity of the sample to one or more chemical stimulus.
11. The method of claim 10 , wherein said chemical stimulus includes exposure to aqueous liquids.
12. The method of claim 10 , wherein said chemical stimulus includes exposure to non-aqueous liquids.
13. The method of claim 1 , wherein the property includes an activity or a reactivity of the sample to one or more biological stimulus.
14. The method of claim 13 , wherein said biological stimulus includes exposure to biological organisms.
15. The method of claim 1 , wherein the agricultural product includes tobacco.
16. The method of claim 1 , wherein the agricultural product includes tea.
17. The method of claim 1 , wherein the agricultural product includes fruit.
18. The method of claim 17 , wherein the fruit includes grapes.
