Offshore buoyant raft culture area extraction method based on SAR and optical image fusion

Abstract

The invention discloses an offshore buoyant raft culture area extraction method based on SAR and optical image fusion. An optical image and SAR image fusion mode is adopted to extract a marine culturearea, a fusion algorithm most suitable for marine culture area extraction is obtained through experiments, and the precision of offshore water area buoyant raft culture area extraction is effectivelyimproved. According to the experimental result, the marine buoyant raft culture range can be accurately defined; the method is beneficial for government departments to more effectively supervise offshore culture areas, standardize the culture density of the culture areas, purify the culture water area environment, relieve the contradiction between the increase of transport ships and the continuous expansion of the culture water area, prevent commercial ships from entering the culture areas by mistake to pollute the culture water area, and ensure the sailing safety of the ships.

Description

technical field [0001] The invention relates to the field of offshore remote sensing extraction, in particular to an extraction method for offshore floating raft breeding areas based on fusion of SAR and optical images. Background technique [0002] Raft farming is to use floating barrels, plastic floats and other materials to build large algae, shellfish and other marine animals in shallow sea areas. As the scale of floating raft farming expands year by year, the near-shore sea space is constantly being developed, and the environmental pressure caused by continuous high-density farming on local sea areas is also becoming increasingly prominent. In recent years, some shellfish farming areas in my country have experienced a decrease in shellfish farming output and an increase in mortality, all of which are caused by improper use of farming resources. Therefore, it is of great significance for the healthy development of the marine aquaculture industry and the sustainable util...
