Abstract

The invention provides an agricultural product pesticide residue detection system for performing rapid nondestructive testing on pesticide residues of vegetables or fruits. The surfaces of agricultural products are irradiated by exciting light to study fluorescence generated by the pesticide residues under the laser irradiation, and the fluorescence images are studied to detect whether there are pesticide residue. The agricultural product pesticide residue detection system performs the following operations: obtaining a first fluorescence image of a first wavelength band and a second fluorescence image of a second wavelength band, and determining a correction image based on the second fluorescence image and a grayscale correction coefficient; determining a detection image based on the firstfluorescence image and the correction image; and performing threshold segmentation on pixel gray values with gray values greater than a threshold in the detection image to determine the distributionof pesticide residues in a sample to be detected, and performing alarm when the pesticide residues exceed the standard.

Description

technical field [0001] The invention relates to a detection system for agricultural products, in particular to a detection system for pesticide residues in agricultural products. Background technique [0002] Food safety is the basis for ensuring people's health. In order to ensure the quality of these foods that are closely related to people's lives, accurate quantitative detection of pesticide residues in fruits, vegetables and other foods has become an urgent problem to be solved. Strengthening the monitoring and research of pesticide residue pollution and developing new technologies and methods for food testing such as vegetables and fruits are of great significance to safeguarding human health, protecting our ecological environment, and reducing agricultural losses. Therefore, there are higher requirements for pesticide residue detection technology. Combined with modern science and technology and other metrology algorithms, the development of fast, simple and high-sensi...
