Ocean Front Identification Method and Device

Abstract

The invention discloses a method and a device for identifying an ocean front. The method includes: inputting the sea surface temperature map to be identified into a multi-scale sampling model for sampling at different scales to obtain multiple blocks of different scales; inputting multiple blocks of different scales into a pre-trained depth model for Model recognition to obtain the recognition results; mark multiple blocks of different scales according to the recognition results; input the marked blocks of different scales into the binary model for splicing, and obtain the size of the sea surface temperature map to be recognized The same binary map; the binary map with the same size as the sea surface temperature map to be identified is input into the fine-grained positioning and demarcation model for fine-grained identification, and the fine-grained identification result is obtained, wherein the fine-grained identification result includes the ocean front The position of the ocean front and the changing trend of the strength of the ocean front. Through the invention, the effect of accurately identifying the position of the ocean front and the changing trend of the strength of the ocean front in the sea surface temperature map is achieved.

Description

technical field [0001] The present invention relates to the field of ocean image recognition, in particular to a method and device for identifying ocean fronts. Background technique [0002] The generation of ocean fronts is a typical mesoscale ocean phenomenon, which is of great value to marine fishery production and ocean research. Therefore, the study of ocean fronts has become an important topic for oceanographers. [0003] The generation of oceanic fronts is due to the fronts formed at the junction of two water masses with different properties (such as: temperature, salinity, density, etc.). In most studies, researchers tend to study ocean fronts due to differences in temperature. Where the front is formed, it is often rich in nutrients, and it is also a place where fish schools gather, which provides an important reference value for marine fishery production. At the same time, relevant data show that ocean climate change is also a condition for the generation of oce...
