Abstract

The invention relates to an island shallow sea water depth prediction method and device based on extreme gradient improvement, a storage medium and computer equipment. The method comprises the following steps of obtaining the multispectral reflectivity of an island shallow sea area; obtaining an actual water depth value of a water depth control point of the island shallow sea area; calculating a suspended sediment content prediction value of the water depth control point according to near-infrared and infrared band reflectivity in the multispectral reflectivity; training an extreme gradient boosting model; and inputting the multispectral reflectance of the island shallow sea area into the extreme gradient lifting model for space-time sequence continuous inversion to obtain a water depth prediction value. The island reef shallow sea water depth prediction method based on extreme gradient lifting has the advantages that the island reef shallow sea water depth can be efficiently and rapidly obtained, and the result is accurate and reliable.

Description

technical field [0001] The present application relates to the technical field of geographic information, in particular to a method, device, storage medium and computer equipment for predicting shallow water depth of islands and reefs based on extreme gradient ascension. Background technique [0002] At present, the water depth measurement of shallow sea areas on islands and reefs mainly relies on unmanned ships equipped with depth sounders to conduct on-the-spot measurements in shallow sea areas on islands and reefs. Can cause damage to unmanned ships, inefficiency and inaccurate measurements. [0003] With the wide application of satellite remote sensing technology, the improvement of water depth measurement method has been promoted, and the water depth measurement by remote sensing water depth inversion method has become a topic worthy of research. Contents of the invention [0004] Based on this, the purpose of the embodiment of the present application is to provide a ...
