The detection of surface contamination and damage of fruits and vegetables (such as animal feces, minor scourges, diseases, worms, etc.) has always been a very important issue for producers and consumers. Ordinary detection methods either have a certain damage to the surface of fruits and vegetables, or can only detect part of the characterization, and cannot be analyzed and detected in depth.
solution:
Using Zolli Hanguang's HyperSIS series hyperspectral imaging detection system in the 400-1000nm visible and near infrared spectral range, comprehensive exposure time, scanning speed and spectral correction and other information can be collected including two-dimensional image pixel information and the first Three-dimensional image block of three-dimensional wavelength information; in addition to using the system, two different images at very close but different wavelengths can be distinguished; a continuous spectral curve of any pixel point and the difference of different substances can also be obtained Spectral curve. Therefore, in the process of surface contamination and non-destructive testing of fruits and vegetables, both complete non-destructive testing and rapid and accurate acquisition of complete image information and spectral information of the sample are achieved
