An embodiment of the present invention provides a map processing method, where the map processing method is applied to a server side serving as a server, and as shown in fig. 1, the map processing method may include:
s101, a server receives a first request sent by an intelligent terminal; the first request comprises position distribution information of a target object in a preset area;
s102, the server acquires initial longitude and latitude coordinates of all target objects in a preset area according to the first request;
s103, the server determines the target longitude and latitude coordinates of each target object according to the initial longitude and latitude coordinates of all the target objects; wherein the precision of the target longitude and latitude coordinates is less than that of the initial longitude and latitude coordinates;

According to the map processing method, the server, the intelligent terminal and the computer readable storage medium provided by the embodiment of the invention, after the server receives the first request sent by the intelligent terminal, the server determines the target longitude and latitude coordinates of each target object according to the initial longitude and latitude coordinates of all target objects in the preset area, at least part of the target longitude and latitude coordinates are subjected to aggregation processing, and the aggregated position distribution information serving as the target objects is fed back to the intelligent terminal. Therefore, when the number of the target objects in the preset area is large, the amount of calculation required by the intelligent terminal for the aggregation processing of the position distribution information of the target objects in the preset area is small, and the page loading speed of the intelligent terminal map is improved.
In practical application, a user of the intelligent terminal may need to view location distribution information of a shared bicycle, express goods, a restaurant, a hotel, a supermarket, a hospital, and the like on a map, so that the target object may be specifically set as the shared bicycle, the express goods, the restaurant, the hotel, the supermarket, the hospital, and the like according to the user requirement in specific implementation, which is not limited herein.
Generally, when searching for a target object in a map webpage of a browser of an intelligent terminal or in a map Application (APP) of the intelligent terminal, a user usually searches in a certain preset area so as to search for a corresponding target object in the preset area. In practical application, a certain numerical value (for example, 2km) is selected as a radius by taking the position of the intelligent terminal as a circle center, and a practical area surrounded by a circle is drawn in a practical environment. And the actual area can be mapped on the map through the proportional relation between the map and the actual environment so as to form a preset area in the map.
Alternatively, the preset area may be represented as a rectangular area defined by latitude and longitude coordinate ranges, for example, x1, x2 for longitude coordinates, y1, y2 for latitude coordinates, and x1< x2, y1< y 2. The preset region may be a rectangular region defined with longitude and latitude coordinates (x1, y1), (x1, y2), (x2, y1), (x2, y2) as four vertices of a rectangle. Of course, the preset region may also be a region with other shapes, and the specific representation manner of the preset region should be determined according to the actual application environment design, and is not limited herein.
In specific implementation, the target object may send the initial longitude and latitude coordinates to the server in real time, or may send the initial longitude and latitude coordinates to the server once every preset time, which is not limited herein. Illustratively, taking the target object as the sharing bicycle as an example, a position monitoring chip is arranged on the sharing bicycle, so as to monitor the longitude and latitude coordinates of the position of the sharing bicycle in real time through the position monitoring chip, and send the longitude and latitude coordinates of the position of the sharing bicycle as the initial longitude and latitude coordinates to the server in real time.
In specific implementation, the number of digits after the longitude coordinate in the initial longitude and latitude coordinate sent by the target object to the server is accurate to a decimal point is the maximum longitude digit which can be confirmed by the position monitoring chip on the target object, and the number of digits after the latitude coordinate is accurate to the decimal point is the maximum latitude digit which can be confirmed by the position monitoring chip on the target object.
In specific implementation, the precision of the target longitude and latitude coordinates is smaller than that of the initial longitude and latitude coordinates, specifically, the precision of the longitude coordinates in the initial longitude and latitude coordinates can be a after the accuracy reaches a decimal point, and the precision of the latitude coordinates can be b after the accuracy reaches the decimal point; the precision of the longitude coordinate in the target longitude and latitude coordinates can be m bits after being accurate to a decimal point, and the precision of the latitude coordinates can be n bits after being accurate to the decimal point; and m < a, n < b.
In specific implementation, the number of digits after the longitude coordinate in the target longitude and latitude coordinate is accurate to the decimal point can be determined according to the number of digits after the longitude coordinate in the initial longitude and latitude coordinate is accurate to the decimal point, and the number of digits after the latitude coordinate in the target longitude and latitude coordinate is accurate to the decimal point can be determined according to the number of digits after the latitude coordinate in the initial longitude and latitude coordinate is accurate to the decimal point. Illustratively, m-a-2, n-b-2, e.g., m-6, n-6, a-4, b-4. Of course, the specific values of a, b, m, and n may be designed and determined according to the actual application, and are not limited herein.
In specific implementation, the specific value of the preset threshold may be arbitrarily selected from 3 to 50, for example, the preset threshold may be 20, may be 30, and may be 50; or, the specific value of the preset threshold may be determined according to the total number of the target objects in the preset area, and of course, the specific value of the preset threshold may be determined according to the actual application environment design, which is not limited herein.
In specific implementation, in the embodiment of the present invention, the server performs aggregation processing on at least part of the target longitude and latitude coordinates according to a preset threshold and the target longitude and latitude coordinates of each target object, and feeds back the location distribution information, which is obtained after the aggregation processing and is used as the target object, to the intelligent terminal, as shown in fig. 2, the method specifically includes:
s201, a server divides the same target longitude and latitude coordinates into a coordinate group, and determines the number of the target longitude and latitude coordinates in each coordinate group;
s202, aiming at each coordinate group, the server judges whether the number of the target longitude and latitude coordinates in the coordinate group is not less than a preset threshold value or not; if yes, go to step S203; if not, executing step S204;
s203, the server carries out aggregation processing on the target longitude and latitude coordinates in the coordinate set, and feeds back the aggregated target longitude and latitude coordinates and the number of the target longitude and latitude coordinates in the coordinate set as position distribution information of the target object to the intelligent terminal;
and S204, the server feeds back all initial longitude and latitude coordinates corresponding to the target longitude and latitude coordinates in the coordinate set and the quantity 1 as position distribution information of the target object to the intelligent terminal.
In specific implementation, if the number of the target longitude and latitude coordinates in the coordinate set is not less than the preset threshold, that is, the number of the target objects corresponding to the same target longitude and latitude coordinate is not less than the preset threshold, it is indicated that the target objects are densely distributed in the area corresponding to the target longitude and latitude coordinates. In order to enable the intelligent terminal to more visually display the areas with densely distributed target objects and the number of the target objects in the areas and reduce the calculated amount of the intelligent terminal, the server carries out aggregation processing on the target longitude and latitude coordinates in the coordinate set, and feeds back the aggregated target longitude and latitude coordinates and the number of the target longitude and latitude coordinates in the coordinate set as position distribution information of the target objects to the intelligent terminal. If the number of the target longitude and latitude coordinates in the coordinate set is smaller than the preset threshold, that is, the number of the target objects corresponding to the same target longitude and latitude coordinate is smaller than the preset threshold, it is indicated that the number of the target objects corresponding to the target longitude and latitude coordinates is small, and even only one target object exists. And the server feeds back all initial longitude and latitude coordinates corresponding to the target longitude and latitude coordinates in the coordinate group and the quantity 1 as position distribution information of the target object to the intelligent terminal so that the intelligent terminal can aggregate the target longitude and latitude coordinates.
In specific implementation, as shown in fig. 3, the map processing method provided in the embodiment of the present invention may further include:
s301, the server receives a second request sent by the intelligent terminal; the second request comprises specific position information of all target objects corresponding to the target longitude and latitude coordinates after at least one aggregation process;
s302, the server determines all initial longitude and latitude coordinates corresponding to the aggregated target longitude and latitude coordinates according to the aggregated target longitude and latitude coordinates;
s303, the server feeds back all the initial longitude and latitude coordinates and the number thereof corresponding to the determined aggregated target longitude and latitude coordinates as specific position information of the target object to the intelligent terminal.
In specific implementation, after the intelligent terminal displays the area with densely distributed target objects and the number of the target objects in the area, the specific position of the target object in the area may need to be further displayed, so that the server feeds back all the initial longitude and latitude coordinates corresponding to the determined aggregated target longitude and latitude coordinates as specific position information of the target object to the intelligent terminal.
In a specific implementation, in the embodiment of the present invention, the server determines, according to the aggregated target longitude and latitude coordinates, all initial longitude and latitude coordinates corresponding to the aggregated target longitude and latitude coordinates, as shown in fig. 4, which may specifically include:
s401, a server acquires initial longitude and latitude coordinates of all target objects in a preset area;
s402, the server determines the current longitude and latitude coordinates of each target object according to the initial longitude and latitude coordinates of all the target objects; and the precision of the current longitude and latitude coordinates is the same as that of the target longitude and latitude coordinates.
S403, the server takes all initial longitude and latitude coordinates corresponding to the current longitude and latitude coordinates which are the same as the aggregated target longitude and latitude coordinates as all initial longitude and latitude coordinates corresponding to the aggregated target longitude and latitude coordinates.
In specific implementation, the precision of the current longitude and latitude coordinates is the same as that of the target longitude and latitude coordinates. Specifically, the longitude coordinate in the target longitude and latitude coordinate can be accurate to m bits after the decimal point, and the latitude coordinate can be accurate to n bits after the decimal point; the longitude coordinate in the current longitude and latitude coordinate can also be accurate to m bits after the decimal point, and the latitude coordinate can also be accurate to n bits after the decimal point; and m < a, n < b.
Based on the same inventive concept, an embodiment of the present invention provides a map processing method, where the map processing method is applied to an intelligent terminal side serving as a client, and as shown in fig. 5, the map processing method may include:
s501, the intelligent terminal sends a first request to a server so that the server can obtain initial longitude and latitude coordinates of all target objects in a preset area according to the first request; determining the target longitude and latitude coordinates of each target object according to the initial longitude and latitude coordinates of all the target objects; according to a preset threshold value and the target longitude and latitude coordinates of each target object, at least part of the target longitude and latitude coordinates are subjected to aggregation processing, and position distribution information serving as the target object after the aggregation processing is fed back to the intelligent terminal; the first request comprises position distribution information of a target object in a preset area; wherein the precision of the target longitude and latitude coordinate is less than that of the initial longitude and latitude coordinate;
and S502, the intelligent terminal receives the position distribution information of the target object fed back by the server and displays the position distribution information.
In specific implementation, in the embodiment of the present invention, the displaying, performed by the intelligent terminal after receiving the position distribution information of the target object fed back by the server, may specifically include:

In specific implementation, when the intelligent terminal receives the position distribution information of the target object, which is fed back by the server, of all the initial longitude and latitude coordinates and the corresponding number 1, the processing and displaying processes may be basically the same as those in the prior art, and are not described herein again.
In specific implementation, in the embodiment of the present invention, the method may further include:
the intelligent terminal sends a second request to the server, so that the server determines all initial longitude and latitude coordinates corresponding to the aggregated target longitude and latitude coordinates according to the aggregated target longitude and latitude coordinates, and feeds back all the initial longitude and latitude coordinates corresponding to the determined aggregated target longitude and latitude coordinates as specific position information of the target object to the intelligent terminal; the second request comprises specific position information of all target objects corresponding to the target longitude and latitude coordinates after at least one aggregation process.
The present invention will be described in detail with reference to specific examples. It should be noted that the present embodiment is intended to better explain the present invention, but not to limit the present invention.
The intelligent terminal sends a first request to the server.
The method comprises the steps that a server receives a first request sent by an intelligent terminal; the first request comprises position distribution information of a target object in a preset area, and the target object is a shared bicycle. The preset area is an area formed by mapping a circular area formed by taking the intelligent terminal as the center of a circle and taking 10km as the radius to the map through the proportional relation between the map and the actual environment.
And the server acquires the initial longitude and latitude coordinates of all the shared bicycles in the preset area according to the first request. The maximum longitude digit which can be determined by the position monitoring chip on the shared bicycle is 6, the maximum latitude digit is 6, the longitude coordinate in the initial longitude and latitude coordinate is accurate to 6 digits after the decimal point, and the latitude coordinate is accurate to 6 digits after the decimal point. For example, if there are 6 sharing bicycles P1 to P6 in the preset area, the server may obtain the initial longitude and latitude coordinates of the 6 sharing bicycles P1 to P6 according to the first request: p1(115.112245, 40.662235), P2(115.112266, 40.662236), P3(115.112367, 40.662236), P4(115.112277, 40.662233), P5(115.112411, 40.772233), P6(115.112422, 40.772233).
The server processes the initial longitude and latitude coordinates of the 6 shared bicycles P1-P6 according to the principle that the longitude coordinate in the target longitude and latitude coordinates is accurate to 4 digits after the decimal point and the latitude coordinate is accurate to 4 digits after the decimal point, and determines the target longitude and latitude coordinates of the 6 shared bicycles P1-P6: p1(115.1122, 40.6622), P2(115.1122, 40.6622), P3(115.1123, 40.6622), P4(115.1122, 40.6622), P5(115.1124, 40.7722), P6(115.1124, 40.7722).
The server divides the same target longitude and latitude coordinates into a coordinate group, and determines the number of the target longitude and latitude coordinates in each coordinate group. Specifically, P1(115.1122, 40.6622), P2(115.1122, 40.6622), P4(115.1122, 40.6622) are taken as a first coordinate set { P1(115.1122, 40.6622), P2(115.1122, 40.6622), P4(115.1122, 40.6622) }, and the target longitude and latitude coordinate number is 3. P3(115.1123, 40.6622) is taken as a second coordinate set { P3(115.1123, 40.6622) }, and the number of target latitude and longitude coordinates is 1. P5(115.1124, 40.7722), P6(115.1124, 40.7722) are taken as a third coordinate set { P5(115.1124, 40.7722), P6(115.1124, 40.7722) }, and the target latitude and longitude coordinate number is 2.
And aiming at each coordinate group, the server judges whether the number of the target longitude and latitude coordinates in the coordinate group is not less than a preset threshold value. Specifically, when the preset threshold is 3, the number of the target longitude and latitude coordinates in the first coordinate set is 3, and is equal to the preset threshold; the number of the target longitude and latitude coordinates in the second coordinate set is 1 and is smaller than a preset threshold value; the number of the target longitude and latitude coordinates in the third coordinate set is 2 and is smaller than a preset threshold value.
And because the number of the target longitude and latitude coordinates in the first coordinate set is equal to a preset threshold value, the server carries out aggregation processing on the target longitude and latitude coordinates in the first coordinate set, and feeds back the aggregated target longitude and latitude coordinates and the number of the target longitude and latitude coordinates in the coordinate set as position distribution information of the shared bicycle to the intelligent terminal. Specifically, the server aggregates the target longitude and latitude coordinates in the first coordinate set to obtain aggregated target longitude and latitude coordinates (115.1122, 40.6622), and then feeds back the aggregated target longitude and latitude coordinates (115.1122, 40.6622) and the number 3 of the target longitude and latitude coordinates in the first coordinate set as the position distribution information (115.1122, 40.6622, 3) of the shared bicycle to the intelligent terminal. The intelligent terminal receives the target longitude and latitude coordinates fed back by the server and the corresponding number as the position distribution information of the shared bicycle, and can directly mark 3 the position corresponding to the aggregated target longitude and latitude coordinates (115.1122, 40.6622) on the map.
Because the number of the target longitude and latitude coordinates in the second coordinate set and the third coordinate set is smaller than a preset threshold value, the server feeds back the initial longitude and latitude coordinates (115.1123, 40.6622) corresponding to the target longitude and latitude coordinates (115.1123, 40.6622) in the second coordinate set and the initial longitude and latitude coordinates (115.1124, 40.7722), (115.1124, 40.7722) and the number 1 corresponding to the target longitude and latitude coordinates (115.1124, 40.7722) in the third coordinate set as the position distribution information (115.1123, 40.6622, 1), (115.1124, 40.7722,1), (115.1124, 40.7722,1) of the shared bicycle to the intelligent terminal. And the intelligent terminal receives all the initial longitude and latitude coordinates fed back by the server and the corresponding number 1 as the position distribution information of the shared bicycle, and displays the position distribution information after aggregation processing.

The initial longitude and latitude coordinates corresponding to the current longitude and latitude coordinates P4(115.1122, 40.6622) are: p4(115.112277, 40.662233). The server may convert the initial latitude and longitude coordinates: and P1(115.112245, 40.662235), P2(115.112266, 40.662236), P4(115.112277, 40.662233) and the number 3 thereof are fed back to the intelligent terminal as specific position information of the shared bicycle so as to be displayed by the intelligent terminal.
