Vehicle demand thermodynamic diagram generation method and device thereof

Abstract

The invention provides a vehicle demand thermodynamic diagram generation method and a device thereof and relates to the thermodynamic diagram technology field. The method comprises the following steps of carrying out grid division on an electronic map in an assigned area; acquiring order data corresponding to each divided grid; according to an order total amount in the order data of each grid, and based on a preset merging rule, merging the adjacent grids in the electronic map and acquiring an electronic grid map, wherein the preset merging rule includes rules of the order total amount in the grids and an adjacent position relation among the grids; according to the order data, taking an order generation place of an internal portion edge of each grid in the electronic grid map as a peak, and connecting each peak so as to generate a polygon area; and coloring the polygon area according to a vehicle demand and acquiring a vehicle demand thermodynamic diagram of a current area. In the invention, accuracy and practicality of the vehicle demand thermodynamic diagram are increased.

Description

technical field [0001] The present invention relates to the technical field of heat maps, and in particular, to a method and device for generating a heat map of vehicle demand. Background technique [0002] With the high development of Internet technology and the popularization of smart devices, Internet car-hailing services are more and more accepted by the public. In order to allocate vehicles reasonably, both car-hailing companies and vehicle drivers need to know the vehicle conditions at various locations in the relevant area (for example, an urban area) in a timely and accurate manner to meet the user's vehicle needs; the distribution of vehicle needs Usually represented by a heatmap. [0003] In the prior art, the traditional heat map is thermally divided by performing differential rendering on the map, or dividing the map into grids; wherein, the method of differential rendering of the map is to display vehicles in the corresponding area on the map in different color...

Problems solved by technology

[0003] In the prior art, the traditional thermal map is divided by differential rendering of the map, or the grid division of the map to perform thermal division; wherein, the method of differential rendering of the map is to display the vehicles in the corresponding area in different colors on the map However, the rendering colors in this method can easily cause the map to be covered, which is not conducive to the user's knowledge of the specific location of the covered area; the method of map grid segmentation can finely divide the map, and when the user clicks on the grid Display the vehicle demand data of the grid, but when there are large areas of green space, rivers or lakes in the grid, it is still not conducive to the user to know the specific location and other information of the hot area of ​​vehicle demand

[0004] In view of the poor accuracy and practicability of the existing vehicle demand heat map, no effective solution has been proposed yet
