Extraction method and system for outer boundary of marine culture area

Abstract

The embodiment of the invention provides an extraction method and system for the outer boundary of a marine culture area. The method comprises the following steps: acquiring satellite remote sensing source data; inputting the satellite remote sensing source data into a pre-trained marine culture area extraction model after the satellite remote sensing source data is processed by a preprocessing program, and obtaining a culture area extraction result output by the marine culture area extraction model, wherein the mariculture area extraction model is obtained by training based on satellite remote sensing sample set images and precision grade labels obtained by classification according to a remote sensing precision identification standard. According to the embodiment of the invention, the monitoring advantages of the satellite remote sensing technology are fully utilized, and the currently widely used deep learning model is combined, so that the purpose of real-time, large-range, accurateand automatic monitoring of the maximum outer boundary of the marine culture area can be achieved.

Description

technical field [0001] The invention relates to the technical field of remote sensing, in particular to a method and system for extracting the outer boundary of a marine breeding area. Background technique [0002] In recent years, with the large increase in the scale and number of ships navigating at sea and the continuous expansion of the marine aquaculture industry, accidents of merchant ships straying into aquaculture areas have occurred from time to time, which not only caused great economic losses to shipping companies and the aquaculture industry, but also affected Ship navigation is safe, and serious incidents may also cause security incidents. Therefore, timely and accurate acquisition of information such as the location and scope of marine aquaculture areas is crucial to ensuring the safety of maritime navigation and anchoring. In traditional maritime supervision, the distribution of breeding areas is usually investigated by ship on-site patrol. On the one hand, t...
