Target and event spatio-temporal change rule visualization method

Abstract

The invention belongs to the field of information science, and particularly relates to a target and event spatio-temporal change rule visualization method. In the prior art, analysis on a spatial change rule of a target and an event in which the target participates along with time is lacked, and a multi-time-scale spatio-temporal rule among four-dimensional relationships of the target, the event, the time and the position cannot be reflected for comparison and analysis. According to the method, according to the spatio-temporal marching relation among multiple targets, the spatio-temporal marching relation among different targets is displayed in a mode of combining colors, arrow directions, lines and graphic signs; according to the multi-target single-event and single-target multi-event spatio-temporal relationship, the spatio-temporal relationship between the target and the event is displayed by adopting a method of combining time period segmentation, graph color depth, different graphs and the graph distance. According to the method, the rules between the targets and the events in which the targets participate under different time scales are mined and displayed, so that the method is easier to understand and has a richer information display effect.

Description

technical field [0001] The method belongs to the field of information science, and specifically relates to a method for visualizing the spatio-temporal changes of objects and events. Background technique [0002] In order to realize the all-day, all-weather, and all-regional integration of aerospace multi-source information and serve national security, command decision-making, and people's livelihood economy, it is not only necessary to know the spatio-temporal laws of the target, but also to know the spatio-temporal laws of the target and the events it participates in , to obtain rich target intelligence information. The key is to carry out research on the space-time change law model and visualization method of targets and events based on my country's existing space-time electronic perception and remote sensing information resources as soon as possible. What the target has done is very likely that the target or other targets will take some action, conduct situational analys...
