Red tide enteromorpha integrated monitoring method based on satellite remote sensing images

Abstract

The invention provides a red tide enteromorpha integrated monitoring method based on satellite remote sensing images, the method comprises inputting image data in a monitoring area to obtain red tideenteromorpha remote sensing information to-be-processed data; respectively using a red tide remote sensing information extraction algorithm and an enteromorpha remote sensing information extraction algorithm to extract the to-be-processed data to obtain red tide enteromorpha remote sensing information extraction results; using a binary image to calculate a red tide enteromorpha coverage area on the basis of the red tide enteromorpha remote sensing information extraction results by combination of the monitoring area, using a scatter point rarefying method to extract the red tide enteromorpha remote sensing information extraction results to obtain scatter point data, and calculating the data to obtain a red tide enteromorpha distribution area; and performing data processing on the red tide enteromorpha coverage area and the red tide enteromorpha distribution area to obtain results, and outputting the results. The method reduces artificial subjective participation and misjudgment, and improves the automation of a monitoring process and the standardization ability of the monitoring results.

Description

technical field [0001] The invention belongs to the technical field of satellite image processing, and relates to an integrated monitoring method for Enteromorpha red tide based on satellite remote sensing images. Background technique [0002] As a marine ecological disaster that has occurred frequently in recent years, when red tide / enteromorpha breaks out in a large area, it will seriously affect the marine environment, destroy the balance of marine fisheries and marine ecosystems, and the process of ecological restoration is extremely long. Therefore, timely and effective monitoring must be carried out, which has important practical significance. In recent years, in response to the urgent needs of marine pollution monitoring, relevant scholars at home and abroad have carried out various researches. Traditional marine pollution monitoring includes closed-circuit television, camera surveillance system, fixed-point sensor monitoring, etc., but it is not suitable for large-sc...
