Embodiment Construction

[0026] like figure 1 As shown, the red tide algae image analysis system includes a light source illumination device, a microscopic imaging device, a specific wavelength color filter, an optical CCD, an image acquisition device, a high-performance computer and image analysis software. The working principle of fluorescence microscopy is as follows: the selected light source carrier plate determines the intensity of the light source, the light emitted by the light source is corrected by a convex lens and becomes parallel light, and then passes through a specific center wavelength filter to become the desired fluorescence excitation light, and then the algae The sample is imaged by a microscopic imaging device, first filtered by a receiving color filter, and then a fluorescence microscopic image is acquired and digitized by a CCD imaging device and an image acquisition card, and then transmitted to a computer. The following sections 1-5 describe in detail the structural characteri...

Abstract

A system for analysing red tide algae image consists of optical source for lighting microscopic imaging device, CCD digital camera, image collecting card, computer and image analysis software. It is featured as setting the first filter at incoming optical source of microscopic imaging device to generate exciting light, and setting the second filter on receiving mouth for filtering the microscopic image.

Description

technical field [0001] The invention relates to an image system and method for identifying and classifying plankton species, in particular to a red tide algae image analysis system and an analysis method thereof. Background technique [0002] With the intensification of marine environmental pollution and seawater eutrophication, red tide disasters are becoming more and more frequent. However, red tide monitoring at home and abroad mostly uses microscopes to manually observe and analyze seawater samples in the laboratory, which is far from satisfying red tides. monitoring needs. At present, there is no image processing and image analysis system for red tide organisms in seawater at home and abroad. [0003] There have been patent literature reports on the use of CCD digital cameras to monitor red tides and lake blue-green algae (marine red tide and lake blue-green telemetry device: CN136499 / Shanghai Jiaotong University (Kong Hainan).-2002.08.21), but its sub-site The on-sit...
