Problems solved by technology

The existing heat map drawing method makes each heat density value correspond to a fixed color value. When the heat density values ​​in the map are small, the color of the drawn heat map may be generally lighter, and when the heat density in the map When the values ​​are large, the color of the drawn heat map may be generally darker, and the color contrast between different positions is not obvious, which greatly reduces the contrast effect of the heat map

[0036] figure 2 It shows the flowchart of the heat map drawing method provided by the first embodiment of the present invention, please refer to figure 2 , the method includes:

[0037] Step S110: Obtain the map to be processed and the thermal data corresponding to the map.

[0038] In this embodiment, firstly, the map to be processed is obtained, and the map is used for drawing a heat map, and the map is selected according to actual needs. For example, if you need to know the passenger flow of some shopping malls, you can obtain the map of the area where the corresponding shopping malls are located to draw a heat map showing the passenger flow; if you need to draw a heat map of the traffic flow corresponding to certain streets, you can obtain the A map of the area where the street is located. Of course, when it is necessary to know the clicks of visitors to certain webpages, the map can also be the corresponding webpage.

[0063] Such as Figure 9 As shown, this embodiment provides a thermal map drawing device 200, which includes:

[0064] A data acquisition module 210, configured to acquire a map to be processed and thermal data corresponding to the map;

[0065] A grid division module 220, configured to divide the map into multiple cells.

[0066] The thermal density value calculation module 230 is configured to calculate the thermal density value corresponding to each of the cells according to the thermal data.

[0067] A color descending gradient calculation module 240, configured to calculate the color descending gradient according to the preset lightest color value, the preset deepest color value, and the maximum heat density value and the minimum heat density value among all the corresponding heat density values ​​of the cells .

[0068] The heat map drawing module 250 is configured to draw a heat map on the map according to the color gradient, the heat density value corresponding to e...

Abstract

The invention provides a thermodynamic diagram drawing method and apparatus and belongs to the image processing field. The method includes the following steps that: a map to be processed and thermodynamic data corresponding to the map are obtained; the map is divided into a plurality of cells; thermodynamic density values corresponding to each cell are calculated according to the thermodynamic data; color descent gradient is calculated according to a preset color shallowest value, a preset color deepest value, a maximum thermodynamic density value and a minimum thermodynamic density value in the thermodynamic density values corresponding to all the cells; and a thermodynamic diagram can be drawn on the map according to the color descent gradient, the thermodynamic density values corresponding to each cell, and the preset color shallowest value.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a method and device for drawing a thermal map. Background technique [0002] Heatmaps are graphical representations that show which areas of the page your visitors are most interested in, or the geographic areas where your visitors are located, in a specially highlighted form. The existing heat map drawing method makes each heat density value correspond to a fixed color value. When the heat density values ​​in the map are small, the color of the drawn heat map may be generally lighter, and when the heat density in the map When the values ​​are large, the color of the drawn heat map may be generally darker, and the color contrast between different positions is not obvious, which greatly reduces the contrast effect of the heat map. Contents of the invention [0003] In view of this, the embodiment of the present invention provides a heat map drawing method and device, aft...
