Thermodynamic diagram generation method and device

Abstract

Embodiments of the invention provide a thermodynamic diagram generation method and device, relates to the field of image processing, and aims at enabling thermodynamic diagrams to continuously and correctly reflect features of areas and enabling changes of image scaling not to influence the continuity and correctness of the thermodynamic diagrams. The method comprises the following steps of: dividing an original image into cells in the current display area of a screen; calculating basic thermal force of a thermodynamic point area of each cell according to statistical data and a thermodynamic weight for generating a thermodynamic diagram; calculating diffusion thermal force suffered by each pixel point in the current display area according to the basic thermal force of the thermodynamic point areas of the cells; obtaining total thermal force of each pixel point in the current display area; and displaying a color corresponding to the total thermal force of each pixel point in the currentdisplay area in the current display area of the original image according to a preset thermodynamic display corresponding relationship, so as to obtain a thermodynamic diagram of the current display area. The method and device are used for generating thermodynamic diagrams.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method and device for generating a thermal map. Background technique [0002] With the rapid development of Internet technology and electronic technology, the Internet and smart terminals have become an indispensable part of people's daily life. For example, accessing webpages to browse required information through the Internet, querying locations or navigation routes through electronic maps, etc. [0003] The user's usage information (location information on the map, click position on the web page) can be aggregated into density data, which describes the density of an area at a certain time point or time period, and describes the corresponding relationship between the area position and the number of people or the number of clicks . Using density data can provide users with many conveniences. For example, using density data in an electronic map can predict road congestion and...

Problems solved by technology

[0007] It can be seen that the heat map generated by the existing heat map technology cannot accurately reflect the actual distribution characteristics and regional characteristics of the image when adjusting the zoom ratio of the image.

And the continuity of the heat map is poor
