Hyperspectral image technology-based saxitoxin nondestructive rapid detection method and system

Abstract

The invention discloses a saxitoxin nondestructive rapid detection method and system based on a hyperspectral image technology, relates to the technical field of saxitoxin detection, and is used for solving the problems that an existing saxitoxin detection method is long in shellfish detection time and complex in operation, and a sample needs to be pretreated. The method is characterized by comprising the following steps: acquiring hyperspectral images of a plurality of shellfish samples; performing spectral data extraction and preprocessing on the hyperspectral image; obtaining an optimal characteristic wave band subset based on a characteristic selection algorithm of fuzzy clustering and particle swarm optimization; inputting the optimal characteristic wave band subset into a saxitoxin nondestructive testing model based on a cost-sensitive probabilistic neural network for training to obtain a trained testing model; and inputting the spectral data of the preprocessed shellfish sample to be detected into the trained detection model to obtain a detection result. According to the method, the hyperspectral image technology is applied to nondestructive testing of saxitoxin, and a new way is provided for solving the food safety problem of shellfish.

Description

technical field [0001] The invention relates to the technical field of shellfish toxin detection, in particular to a non-destructive and rapid detection method and system for shellfish toxins based on hyperspectral image technology. Background technique [0002] my country is the largest shellfish breeding country in the world. In the past ten years, a large amount of untreated industrial, agricultural and domestic wastewater has been directly discharged into the ocean, resulting in eutrophication of water bodies, frequent occurrence of red tides, and flooding of red tide toxins. Marine shellfish enrich the toxins in the body through filter feeding, and then enter the human body through the food chain, seriously endangering the health of the eaters, and even threatening their lives. Food is the first priority for the people, and food safety is the first priority. The pollution of shellfish toxins not only causes huge economic losses to the mariculture industry, but also pose...
