Plankton particle size spectrum detection system and method thereof

Abstract

The present invention provides a plankton particle size spectrum detection system and a method thereof. The system comprises an image acquisition processing unit, a target detection unit, an edge information extraction unit, and a counting unit that are sequentially connected. The image acquisition processing unit preprocesses a collected video image IO to obtain a preprocessed image I1; the target detection unit separates the plankton in the preprocessed image I1 from the background image to obtain a target image I2; the edge information extraction unit carries out detection and extraction on the closed-loop edge contour of the target image I2 to obtain contour information of each plankton in the target image I2; and the counting unit detects the amount of plankton in different particle sizes to generate the plankton particle size spectrum of the correspondence between the different particle sizes of the plankton and the amount of plankton. According to the system and method provided by the present invention, the amount of plankton particle size spectrum detection can be effectively simplified, automatic detection of the plankton particle size spectrum in the seabed can be accurately carried out in situ in time, and the red tide can be effectively detected and forecasted.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a plankton particle size spectrum detection system and a method thereof. Background technique [0002] About 71% of the earth's surface is covered by oceans. The huge area of ​​the oceans has bred rich natural resources. Today, when land resources are increasingly scarce, more and more countries have turned their attention to the oceans. The particle size structure of marine plankton is an important aspect of the marine ecological community structure and an indicator with important ecological significance and application value. The distribution of energy flow in the marine ecosystem depends to a large extent on the size of biological particles. Biological particle size spectrum, also known as biological particle spectrum, refers to the correspondence between the number or biomass of plankton and the size of biological particles, that is, the distribution of organisms in ...
