Method and device for displaying heat map

Abstract

The invention provides a thermodynamic diagram showing method and device. By adopting the embodiment, a showing ratio of a target image is obtained and thermodynamic parameters are further obtained according to the showing ratio so that a thermodynamic diagram corresponding to the target image is shown according to statistical index data of the target image and the thermodynamic parameters; the thermodynamic diagram is shown by adopting the thermodynamic parameters corresponding to the showing ratio of the target image, so that the problems in the prior art that set thermodynamic parameters are adopted so that a distribution condition of the statistical index data of the target image can not be clearly shown by the thermodynamic diagram can be avoided, and thus, the showing reliability of the thermodynamic diagram is improved.

Description

【Technical Field】 [0001] The present invention relates to heat map technology, in particular to a method and device for displaying heat map. 【Background technique】 [0002] The heat map can obtain several statistical index data according to certain statistical standards, and use a special highlight form to indicate the size of the statistical index data of each area in the target image, thereby visually displaying the global characteristics of the area in front of people a method. The heat map can be applied to various target images. For example, the map heat map is a service that uses blocks of different colors to be superimposed on the map to describe the population distribution, density and change trend in real time. It is a convenient travel based on Baidu big data service. In the prior art, an operator can set a fixed thermal parameter, such as a color attribute reference value and a thermal radius, etc., for displaying the thermal map according to the set thermal paramete...

Problems solved by technology

[0003] However, because some services involved in the heat map can have different display ratios, such as the zoom level of the map, etc., using the fixed heat parameters set will make the heat map unable to clearly show the distribution of statistical index data of the target image For example, if the display ratio becomes larger, the existing color distribution will be more scattered, and if the display ratio becomes smaller, the existing color distribution will be particularly concentrated, etc., resulting in a reduction in the reliability of the display of the heat map
