Abstract
A method and a system for pollutant identifying and early warning based on cluster analysis include steps of: installing multiple high-definition cameras on a river or a sluice dam, capturing pollutant images in front of the sluice dam at certain intervals, and transmitting the pollutant images captured by the high-definition cameras to a computer; reading the pollutant images transmitted to the computer; extracting a main pollutant color in the pollutant images through cluster analysis; calculating a difference between the main pollutant color and RGB data in a pollutant color gamut database, and setting an aberration threshold to identify the pollutant color; performing scale conversion with two sets of common point image pixel coordinates and actual plane coordinates to calculate a current pollutant area; and judging whether a polluted area exceeds a critical value according to a preset pollutant area threshold, thereby realizing early warning.
