Drawing method and device of vehicle geographic position distribution map, and storage medium

Abstract

The invention discloses a method and a device for drawing a vehicle geographic position distribution map, and a storage medium. The method comprises the following steps: taking the maximum longitude and latitude and the minimum longitude and latitude of each region as the longitude and latitude range of each region; comparing the longitude and latitude of the vehicle with the longitude and latitude range of each region, and preliminarily judging the region where the vehicle is located; if a plurality of areas where the vehicle is located are preliminarily judged, judging the number of times of intersection between any ray taking the longitude and latitude of the vehicle as the end point and the polygon of each area where the vehicle is located, and further analyzing the area where the vehicle is located according to the number of times of intersection; if the area where the vehicle is located cannot be confirmed, the unique area where the vehicle is located is judged according to the longitude and latitude of the vehicle by adopting an inverse address resolution method; counting the total number of vehicles in each area, and performing distinguishing marking on each area according to the total number of vehicles to obtain a vehicle geographic position distribution map; according to the method, a large number of inverse address analysis instructions do not need to be used, the processing speed is higher, and vehicle distribution in each region is clearer.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a method and device for drawing a geographic location distribution map of a vehicle, and a storage medium. Background technique [0002] In today's increasingly mature automotive Internet technology, mastering the geographical distribution of cars can intuitively view the most concentrated areas of cars, so as to make appropriate adjustments to the sales or tracking of car-related products. Most of the existing car geographical location distribution maps are car distribution heat maps. The car distribution heat map is to trace the geographical location of the car on the map, and deepen or lighten its color according to its weight. The heat map can display the geographical distribution of vehicles well when the number of vehicles is small, but the disadvantage is that when the number of vehicles is very large and the range is very wide, a large dark area will be displayed on the map. area...

Problems solved by technology

Most of the existing geographical distribution maps of automobiles are heat maps of automobile distribution. The heat map of automobile distribution is to depict the geographical location of automobiles on the map, and deepen or lighten the depth of its color according to its weight. This heat map can display the geographical distribution of vehicles well when the number of vehicles is small, but the disadvantage is that when the number of vehicles is particularly large and the range is particularly wide, a large dark area will be displayed on the map area, such as figure 1 As shown, the distribution of cars on the entire map is large and wide at this time, and it is impossible to accurately identify the area with the largest number of cars, and it is difficult to obtain the specific distribution situation intuitively.

[0003] Moreover, in the prior art, in order to obtain the location of the car, it is necessary to perform reverse address resolution on the last reported position of each car, and due to the large number of vehicles, a large number of reverse address resolution requests are required to the server, so the requirements for the server are relatively high. High, it takes a lot of cost to upgrade the server, and the data processing will fluctuate according to the network conditions, resulting in data that cannot reflect the distribution of vehicles in real time
