Embodiment Construction

[0059] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0060] Method example:

[0061] This embodiment proposes an image generation method based on the geographical relationship of the country, which specifically includes the following steps:

[0062] Step 1: Take the country as the node (hereinafter referred to as the country node), and use the geographical location and geographical relationship to arrange the country node. Such as figure 1 As shown, the specific steps are as follows:

[0063] (1) Obtain the geographic location coordinates of each country as the initial position of each country node.

[0064] (2) Calculate the magnitude of the gravitational force between the nodes of two countries and the coordinate displacement caused by the gravitational force; calculate the magnitude of the repulsive force between the nodes of two countries and the coordinate displacement caused by the re...

Abstract

The invention relates to an image generation method and device based on the national geographical relationship, and belongs to the technical field of visual analysis of the geographical relationship, and the method comprises the steps: firstly, arranging each country node in an image for geographic positions between different countries and geographical relationship values between a target country and other countries; secondly, classifying country nodes, performing regional division on the image, regarding the country nodes as charged particles, calculating potential energy of each divided region, determining all equipotential lines in the same category by utilizing potential energy continuity, and determining contour lines containing all equipotential lines in the category; and finally, traversing a connection path between every two country nodes under each category, adding proper virtual nodes, updating the connection path, and preventing the path directly connected between the two country nodes from passing through the country nodes which do not belong to the current category. The image generated by the method effectively and reasonably displays the geographical relationship between the countries, the visualization is strong, and the analysis of the geographical relationship between the countries is facilitated.

Description

technical field [0001] The invention belongs to the technical field of visual analysis of geographical relations, and in particular relates to an image generation method and device based on national geographical relations. Background technique [0002] Geo-relationships are the core issues of geo-environmental research. Research on geo-relationships between countries aims to establish a network of relationships between countries and analyze its network structure. The current research on geo-relationships mainly analyzes the relevant data through the establishment of calculation models to obtain relatively accurate results, but the expression of the analysis conclusions is still in the form of text reports, data tables, etc. Accurate characterization of complex relationships. [0003] In the prior art, in December 2018, the author Wen Huiqi and others published an article titled "Research on Visual Analysis of Geo-environment under Big Data" in the journal "Surveying and Map...
