Application of hyperspectral technology in the detection of crop diseases and pesticide residues

Hyperspectral imaging (HSI) is one of the most promising techniques for nondestructive evaluation of agricultural products. Modern society requires that the detection technology can achieve a reliable and accurate assessment of the severity of agricultural diseases. As a non-destructive detection technology, hyperspectral imaging technology can be used in the non-destructive detection of agricultural products, combined with appropriate spectral pretreatment to make it more comprehensive. This paper summarizes the principle, equipment and image advantages of hyperspectral imaging, introduces the application examples and limitations of hyperspectral imaging technology in nondestructive testing of agricultural products and pesticide residues detection in recent ten years, and makes a longitudinal comparison of researchers'' research. Finally, the related problems and prospects of hyperspectral imaging technology are discussed. The research is also committed to early detection of agricultural diseases, increasing the yield of agricultural products and reducing the planting cost of agricultural products.
