Ship distribution thermodynamic diagram construction method based on VTS system

Abstract

The invention discloses a ship distribution thermodynamic diagram construction method based on a VTS system. The method includes the steps of ship information acquisition and classification, region weight information layer establishment, ship position layer establishment, layer matching and fusion, color region division and screen display. In other words, ship navigation information and navigation region information collected by an existing VTS system terminal are used for conducting division of different regions such as ports, passages, bridges and common water surfaces and drawing specific basic weight distribution diagrams of the regions; the radiation radius is set with the ship position point as the center, then a pixel table based on Gaussian distribution is generated, and linear superposition is conducted on normal curve data in a ship radiation overlap region. The overall distribution and tendency of ships can be reflected by directly mapping ship layer values to a color space; information such as the region loading degree and attention degree can be reflected by fusing the ship layer and the region basic weight layer, mapping the fused layers to the color space and displaying the layers on a general map, and workers can extract key information very conveniently.

Description

technical field [0001] The invention relates to the field of VTS system data visualization, in particular to a method for constructing a ship distribution heat map based on the VTS system. Background technique [0002] The modern Vessel Traffic Management System (VTS, Vessel Traffic Management System) can already accurately display information such as the position and course of ships on the water on the electronic chart platform. However, in practical applications, relevant personnel have to analyze the overall situation of the waterway based on discrete information points, and when selecting key monitoring areas, there will be problems such as data search difficulties and regional judgment deviations. [0003] In view of this situation, it is necessary to display the number and position of ships in a way different from the traditional way of directly drawing ships on the map. It is necessary to construct a layer in connection with the actual situation of ports or waterways...
