Berth identification method and device based on ship track

Abstract

The embodiment of the invention provides a berth identification method and device based on a ship track. The method comprises the following steps: obtaining altitude data and a ship historical track in a preset longitude and latitude range; constructing an altitude dictionary table and a seaworthiness area dictionary table; determining a potential berth track point segment through a historical track of the ship; using a density clustering method to divide track point segments, center point position information of potential berths is determined, then using the center point position informationof the potential berths for inquiring and recognizing real berths in a seaworthiness area dictionary table, and therefore the global real berths can be quickly and automatically recognized.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for identifying berths based on ship tracks. Background technique [0002] With the development of the shipping service industry, a large number of ship trajectories have been accumulated, with hundreds of millions of trajectories every day. Based on the ship trajectory, the ship calling system is designed and implemented to record the arrival and departure events of ships and ports around the world. Based on the ship call data, the cargo type identification algorithm was designed and implemented, and then the global bulk commodity information website was launched to calculate the shipping data of global coal, iron ore, grain, oil, LNG, LPG and other bulk cargo. However, after the vessel call data was launched online, it was found that some vessels lacked voyages, and the reason for the missing data was the lack of port data, part of which was caused by the...

AI Technical Summary

Problems solved by technology

However, after the online ship calling data on the ship information network, it was found that some ships lacked voyages, and the reason for the missing data was the lack of port data, part of which was caused by the lack of berths.

[0003] With the rapid development of the economy, port facilities continue to expand, and many new berths have appeared, but the official port data released regularly cannot meet the timely needs of business development

In the existing technology, solutions related to berth excavation have been proposed, but most of them are the allocation technology of existing berths and the analysis of ship navigation anomalies, and no effective technical solutions have been formed for the automatic identification of global real berths.
