Ocean front area acquisition method and device, computer equipment and storage medium

Abstract

The invention relates to an ocean front area acquisition method and device, computer equipment and a storage medium. The method comprises the following steps: determining a roughly estimated ocean front area, target paths for a plurality of unmanned naval vessels to reach the roughly estimated ocean front area and target duration for the unmanned naval vessels to reach the roughly estimated oceanfront area along the target paths according to acquired satellite remote sensing observation data; determining each initial position of each unmanned ship in the roughly estimated ocean front area according to received arrival confirmation information sent when each unmanned ship reaches the roughly estimated ocean front area; outputting an adjustment instruction according to the region change information of the roughly estimated ocean front region determined by the multiple groups of satellite remote sensing observation data received within the target duration to indicate each unmanned ship to perform adjustment based on the respective corresponding initial position so as to obtain the adjusted position of each unmanned ship; and determining a target ocean front area according to each received adjusted position. By adopting the method, the identification accuracy of the ocean front area in the sea area can be improved.

Description

technical field [0001] The present application relates to the technical field of ocean front identification, in particular to a method, device, computer equipment and storage medium for acquiring an ocean front area. Background technique [0002] The narrow intersection zone between two or several water bodies with obviously different properties in the ocean is called the ocean front. and other elements; and the scale of the ocean front can reach hundreds of kilometers, existing in the surface layer, middle layer and bottom layer of the ocean. It affects shipping and fishery, and also affects underwater communication, ship safety, maritime search and rescue and other activities. Therefore, accurate identification of ocean fronts is one of the current problems that need to be solved urgently. [0003] In the traditional technology, when using the gradient threshold method to identify the ocean front area in the sea area, a reasonable threshold is set according to different s...

Problems solved by technology

[0004] However, the current traditional method is difficult to set a reasonable threshold for different sea areas and seasons, resulting in low accuracy in the identification of ocean front areas in sea areas
