AI Technical Summary

Technical Problem

In the complex waterway field, the water area is wide, and the jump range of ship trajectory points and personnel on board is wide, resulting in discontinuity of trajectory data, which in turn produces large errors in water data processing, making it difficult to meet the requirements of water data management.

Method used

By obtaining the identification code and latitude point data of the target user in the operator data and information collection equipment, correcting the latitude point data based on the association relationship of the identification code, a more reliable data set is obtained, and matching ship data is calculated through grid encoding to determine the ship data corresponding to the target user.

Benefits of technology

It greatly improves the reliability of the target user's latitude and longitude point data, reduces data errors caused by the large jump range of water environment and complex trajectory points, improves the accuracy and efficiency of water data processing, and meets the requirements of water data management.

Abstract

The present invention discloses a water area data processing method, device and system, wherein the method comprises: obtaining a first identification code and a first longitude and latitude data set with a time sequence of a target user in operator data; obtaining a second identification code and a second longitude and latitude data set with a time sequence of the target user in an information acquisition device; based on the association between the first identification code and the second identification code, using the second longitude and latitude data set to perform a correction operation on the first longitude and latitude data set to obtain a third longitude and latitude data set; performing grid coding calculation on the third longitude and latitude data set to obtain first grid data; obtaining second grid data of each ship within a preset waterway basin; matching the first grid data in the second grid data of all ships, determining the ship data in the water area data corresponding to the target user, reducing the error of water area data processing, improving the accuracy of water area data processing, and meeting the requirements of water area data processing.
