Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.

Referring to fig. 1, fig. 1 shows a Web Application list interface, in which at least one icon and name of a Web Application are displayed, and the Web Application can be started by clicking the icon or the name. In particular, a web application is an application written in a web language that is built based on standard web technology. Unlike traditional websites, the Web App emphasizes allowing users to perform various operations, rather than simply browsing the content of a Web page. Such as sending an email, finding a house, paying a bill, transferring money, shopping, sending an invitation, etc. The traditional webpage has content guidance, static information is used for providing convenient browsing and consumption, and the webpage application program is an application which can be used without downloading and installing, namely without installing and uninstalling.

The web application may be attached to the target client, that is, the user can start the web application in the target client, the target client may be a browser client, the web application function is also a web page opened by the browser client, and the target client may also be a non-browser client, for example, the target client may be a wechat, and the web application is an applet in the wechat. The web application may be based on the architecture of the target client and written in html5 language.

Each web application can implement a function, in the embodiment of the present application, the web application can display the location of the user and the location between the user and the destination, that is, a map interface can be displayed, the location of the user is displayed in the map interface, or the location and the destination location of the user are displayed at the same time, and even other contents can be displayed, for example, information of merchant stores, tourist attractions, and the like near the location of the user.

However, the inventor has found in research that, when displaying map content, a web page or a web application needs to call map software to obtain location information of a user and other location information. Specifically, the web Application and the map software may be connected through an Application Programming Interface (API), that is, the web Application sends a location data obtaining request to the map software through the API, and the map software obtains the location data from a server corresponding to the map software and sends the location data to the web Application. Then, in the process, map software needs to be called and a network needs to be used to obtain the position data, so that the speed of displaying the map content is affected by the network quality, and when the network quality is poor, for example, when the network speed is too slow, the network is unstable or the network packet loss is severe, the speed of obtaining the position data by the web application program is too slow, so that the speed of displaying the map content by the web application program is too slow, the waiting time of a user is too long, and the user experience is poor.

In order to overcome the above drawbacks, embodiments of the present application provide a content display method and apparatus, where when determining location information of a location of the user and location information of a destination, map software is not used, but is obtained through a built-in positioning algorithm, so that a speed of calling the map software, which is too slow due to a poor network when the map software is called, can be reduced.

Specifically, referring to fig. 2, fig. 2 shows a content display method, which is applied to the web application program, but may also be applied to a web page of a browser or other application software, which is not limited herein, and specifically, the method includes: s201 to S204.

S201: first position information of a user position and second position information of a target position are acquired.

The first position information and the second position information are Coordinate points in a world plane Coordinate System, wherein the world plane Coordinate System can be regarded as a projection Coordinate System of a Geographic Coordinate System and is a plane Coordinate, wherein the Geographic Coordinate System (Geographic Coordinate System) is a spherical Coordinate, and defines the surface position of the earth by using a three-dimensional spherical surface, so as to realize a Coordinate System which is referenced to the surface position of the earth by longitude and latitude, and each point in the Geographic Coordinate System is represented by longitude and latitude. The Projection Coordinate System (Projection Coordinate System) is a kind of plane coordinates. The projection coordinate system uses a coordinate system based on X, Y values to describe where a point on the earth is located. This coordinate system is obtained by projecting from an approximate ellipsoid of the earth, and a certain area on a map is usually projected on a plane, and the formed coordinate system is called a projection coordinate system. The world plane coordinate system may be a WGS-84 coordinate system, a GCJ-02 coordinate system, a BD-09 coordinate system, or the like, without limitation.

As an implementation manner, the implementation manner of acquiring the first location information and the second location information may be to acquire a first longitude and latitude of the user location and a second longitude and latitude of the target location, and obtain the first location information of the user location and the second location information of the target location according to the first longitude and latitude of the user location and the second longitude and latitude of the target location. Specifically, the first longitude and latitude and the second longitude and latitude may be coordinate values of the user and the target location in a geographic coordinate system, and the first location information corresponding to the first longitude and latitude and the second location information corresponding to the second longitude and latitude may be determined in a coordinate projection manner.

In some embodiments, for some scenarios where the target location is fixed, the second location information of the target location may be pre-stored, and when the first location information of a new user is obtained again, the second location information of the target location may not be determined again, but may be directly read. In other embodiments, for some scenes in which the target position changes in real time or the change frequency is high, the second position information of the target position may be obtained again at the same time of obtaining the first position information of a new user.

As an embodiment, the operation of acquiring the first location information of the user location and the second location information of the target location based on the positioning algorithm preset by the web application may be triggered based on a request of the user. For example, when the web application is running, the user inputs a display request of a custom map in the web application, and when the web application detects the request, the operation of acquiring the first location information and the second location information is performed.

As another embodiment, when the designated interface of the web application is displayed, the operation of acquiring the first position information of the user position and the second position information of the target position based on the positioning algorithm preset by the web application may be automatically performed. Wherein the designated interface can be an interface for displaying the custom map.

S202: and acquiring user position information corresponding to the first position information and target position information corresponding to the second position information based on a preset scale of a user-defined map and an included angle between a plane where the user-defined map is located and a plane where the world plane coordinate system is located.

In one embodiment, the user location information and the target location information are both located in a map coordinate system, and the map coordinate system is a plane coordinate system corresponding to the custom map. The custom map can be regarded as a Canvas (Canvas) provided by a webpage application program, the Canvas is an HTML5 element used for drawing graphics, and drawing paths, images and various graphics are completed through scripts (e.g., JavaScript). The plane coordinate system corresponding to the customized map may be regarded as a screen coordinate system, and as an embodiment, the plane coordinate system may be a screen coordinate system corresponding to a screen of the electronic device running the web application. The customized map may be a screen coordinate system corresponding to the whole screen, or may be a coordinate system corresponding to a certain partial area of the screen, specifically, determined by the display size of the customized map on the screen.

Because the distance between the user position and the target position in the world plane coordinate system is far larger than the size of the customized map, the position relationship between the first position information and the second position information can be presented in the customized map only by zooming the first position information and the second position information according to the scale of the customized map. In addition, an included angle may exist between the plane of the customized map and the plane of the world plane coordinate system, that is, the plane of the customized map and the plane of the world plane coordinate system may not be in a parallel relationship, specifically, the plane of the customized map may refer to the plane of the canvas, and the plane of the world plane coordinate system is parallel to the screen on which the screen coordinate system is located, that is, if each point in the world plane coordinate system is directly displayed on the screen, the viewing angle of each point in the world plane coordinate system viewed by the user through the screen should be an angle perpendicular to the ground plane. Therefore, the included angle between the plane of the custom map and the plane of the world plane coordinate system can be regarded as the visual angle of the custom map relative to the custom map when the custom map is displayed on the screen and the user looks at the screen.

Because the included angle between the plane of the customized map and the plane of the world plane coordinate system may cause the angular relationship and the distance between each position point of the world plane coordinate system to change due to the included angle, for example, if the first position point in the world plane coordinate system is located right above the second position point, the first position point may be located right above, left above, right below or left below the second position point in the customized map, specifically, if the inclination direction of the plane of the customized map relative to the plane of the world plane coordinate system is different, the angle value of the included angle may be different, and further, the positional relationship between the first position point and the second position point may be different, specifically, based on the preset scale of the customized map and the included angle between the plane of the customized map and the plane of the world plane coordinate system, the following embodiments may be referred to for the implementation of obtaining the user location information corresponding to the first location information and the target location information corresponding to the second location information.

S203: and adding first mark content and second mark content in the custom map based on the user position information and the target position information.

The first marking content is used for marking the user position in the custom map, and the second marking content is used for marking the target position in the custom map. The marking content may be at least one of a pattern and a text. As an embodiment, the first and second mark contents may both be patterns, and the first and second mark contents may be patterns having the same shape but different colors or sizes. In other embodiments, the target and the user may both be people, a first avatar of the user and a second avatar of the target may be obtained, the first avatar being the first tagged content and the second avatar being the second tagged content. If the target is a place name, for example, a city or a country. The first marked content is the head portrait of the user, and the second marked content is the pattern of the landmark corresponding to the target.

In some embodiments, in addition to the user position information and the target position information, other position information within the range of the user position and the target position may be obtained, for example, the positions of other landmarks within the area range of the user position information and the target position information, where the landmarks may be buildings, mountains, rivers, or the like, and mark content corresponding to the positions of other landmarks is also added in the customized map, so that the content displayed by the customized map can be richer.

S204: and displaying the customized map added with the first mark content and the second mark content in a specified interface.

The designated interface may be the interface for triggering the web application to acquire the first location information of the user location and the second location information of the target location, for example, the interface may be a home page of the web application, or may be an interface on which a trigger button is displayed, and the user triggers the web application to acquire the first location information of the user location and the second location information of the target location by triggering the trigger button, or of course, may be other interfaces, which are not limited herein.

Therefore, when the position information of the user position and the position information of the destination are determined, the map software is not used, but is acquired through a built-in positioning algorithm, and the speed of calling the map software due to poor network when the map software is called can be reduced. In addition, the user position and the target position are displayed on the customized map of the webpage application program, and the content in the map display interface of the map software is not used, so that the displayed content is more in line with the display requirement of the webpage application program, and the time consumed for acquiring the data of the map display interface of the map software can be reduced.

Specifically, referring to fig. 3, fig. 3 illustrates a content display method, which is applied to the web application, but may also be applied to a web page of a browser or other application software, which is not limited herein. Specifically, the method comprises the following steps: s310 to S360.

As an implementation manner, the first location information may be determined according to the latitude and longitude of the user location, and the second location information may be determined according to the latitude and longitude of the target location. As shown in fig. 4, the S310 includes: s311 to S313.

And the first longitude and latitude and the second longitude and latitude are coordinate values of the user position and the target position in the geographic coordinate system. As an embodiment, the user position may be collected by a positioning module in the user terminal, wherein the positioning module may be a GPS locator or a base station positioning system. The user terminal may be a terminal for running the web application, for example, the user terminal may be an electronic device capable of running the application, such as a smart phone, a tablet computer, and an intelligent wearable device. And the second longitude and latitude of the target position can be acquired by other terminals with positioning functions and is given to the webpage application program, so that the webpage application program can acquire the second longitude and latitude of the target position.

S312: and determining the latitude and longitude area range based on the designated position area corresponding to the self-defined map.

In one embodiment, the customized map corresponds to a designated location area that is an area that the web application wishes to display on the customized map, for example, the designated location area may be an area within a designated distance of the target location, for example, an area within 100 kilometers of the target location.

As an embodiment, if the target location is a fixed location or a location with a small variation frequency, the designated location area is an area capable of covering the target location, for example, if the target location is a certain city, the designated location area includes the certain city, that is, the designated location area may be determined based on the longitude and latitude of the target location. As another embodiment, a target area corresponding to the target location may be further determined, and the area capable of covering the target area is used as the designated location area, where the target area may be set according to an actual requirement, and the target area is larger than the area corresponding to the target location, for example, if the target location is a certain city, the target area may be a province or a country where the certain city is located.

In one embodiment, the web application sets a plurality of location points from which the designated location area is determined, and specifically, an outline area may be formed from the plurality of location points, and the outline area is the designated location area. In some embodiments, the number of the plurality of location points is 4, the designated location area is a rectangle, the 4 location points are 4 vertices of the rectangle, each vertex corresponds to a longitude and latitude, and the 4 location points are used for determining a minimum longitude and latitude, a maximum longitude and latitude, a southwest corner longitude and latitude, and a northeast corner longitude and latitude, so that the designated location area can be determined. Specifically, the minimum longitude and latitude, the maximum longitude and latitude, and the southwest angle longitude and latitude and the northeast angle longitude and latitude can be obtained through a mapcontext.

As shown in fig. 5, the points O, a, B, and C are 4 vertices that are preset, each vertex corresponds to one longitude and latitude, the X axis is the longitude direction, the Y axis is the latitude direction, the latitude values of the points on the X axis are the same and different, the longitude values of the points on the Y axis are the same and different, the point O is located in the north direction of the point a and in the west direction of the point C, and a rectangular area surrounded by the points O, a, B, and C is regarded as a designated location area. The minimum latitude of the O point is the largest, the maximum latitude of the C point is the largest, the minimum latitude of the A point is the smallest, the maximum latitude of the B point is the smallest, the southwest angle longitude and latitude is the longitude and latitude of the A point, and the northeast angle longitude and latitude is the longitude and latitude of the C point.

S313: and determining first position information of the first longitude and latitude in the world plane coordinate system and second position information of the second longitude and latitude in the world plane coordinate system.

Assuming that the point O is the origin of coordinates, a world plane coordinate system of the XOY plane is established along the X direction and the Y direction, as shown in fig. 6, the world plane coordinate system is a plane projection coordinate system corresponding to a specified location area surrounded by the point O, the point a, the point B, and the point C, that is, the world plane coordinate system is a plane coordinate system corresponding to the latitude and longitude area range. And coordinate values of the longitude and latitude of each position point in the specified position area in a world plane coordinate system can be obtained based on the longitude and latitude of each point.

Specifically, the shape of the earth approximates an ellipsoid with the two poles being flat and the largest radius at the equator. The average radius of the equator is: 6378137m, half of the distance between the two poles of the earth, and the length of the semiminor axis is 6356752 m. Let the longitude and latitude of the O point be (o.lng, o.lat), where o.lat represents the latitude of the O point and o.lng represents the longitude of the O point. The longitude and latitude of the point B are (b.lng, b.lat), where b.lat represents the latitude of the point B and b.lng represents the longitude of the point B.

Let MACRO _ AXIS be 6378137, i.e. average radius of equator, and MINOR _ AXIS be 6356752, i.e. MINOR _ AXIS is half of earth's polar distance. Let a be MACRO _ AXIS²That is, a is the square of the average radius of the equator, and b is assumed to be MINOR _ AXIS²I.e. b is the square of half the distance between the two poles of the earth.

Definition c ═ (tan (2 · o.lat ·/360))²，

The X-axis coordinate X of the point B is obtained according to the following formula (1)_b：

x_b＝d*(2*b.lng*π/360-2*o.lng*π/360) (1)

The X-axis coordinate X of point B_bThe value of (2) can be used as the difference value of the coordinate values of the X axis between the point O and the point C in the world plane coordinate system, namely, the distance of OC, and the width value of the designated position area in the world plane coordinate system.

Definition e ═ 1/tan (2 ═ pi/360)²，

Then f ═ tan (2 ═ b @/360) can be obtained²，g＝1/tan(2*b.lat*π/360)²，

The Y-axis coordinate Y of the point B is obtained according to the following formula (2)_b：

I.e., the value of Y obtained according to the formula (2) as the coordinate Y of the Y-axis of the B point_b。

The Y-axis coordinate Y of point B_bThe value of (b) may be a difference value of the Y-axis coordinate value between the point O and the point a in the world plane coordinate system, that is, a distance of OA, and may be a height value of the designated location area in the world plane coordinate system.

Thus, the coordinates (x) of the point B in the world plane coordinate system can be specified by the above equations (1) and (2)_b，y_b). When first position information of a first longitude and latitude of a user position in the world plane coordinate system needs to be acquired, the longitude value and the latitude value corresponding to the first longitude and latitude can be substituted into the formulas (1) and (2), namely b.lng in the formula is replaced by the longitude value corresponding to the first longitude and latitude, b.lat in the formula is replaced by the latitude value corresponding to the first longitude and latitude, and then first position information, namely a coordinate (x) of the user position in the world plane coordinate system is acquired according to the formula_n,y_n). Similarly, when second position information of the second longitude and latitude of the target position in the world plane coordinate system needs to be acquired, the longitude value and the latitude value corresponding to the second longitude and latitude can be substituted into the formulas (1) and (2), namely b.lng in the formula is replaced by the longitude value corresponding to the second longitude and latitude, b.lat in the formula is replaced by the latitude value corresponding to the second longitude and latitude, and then second position information, namely the coordinate information of the target position in the world plane coordinate system is acquired according to the formulas(x_m,y_m)。

S320: and determining third position information corresponding to the first position information and fourth position information corresponding to the second position information in the map coordinate system based on the scale of the self-defined map.

It should be noted that the third position information and the fourth position information may be positions of the user position and the target position in the map coordinate system, or may be position information after the third position information and the fourth position information are changed according to an angle difference between the map coordinate system and the world plane coordinate system, as positions of the user position and the target position in the map coordinate system.

Then, assuming that the scale of the custom map includes the width value and the height value of the custom map, the width value of the custom map is named as cWidth, and the height value of the custom map is named as cwight, that is, the width of the map coordinate system is cWidth, and the height is cwight.

The coordinates of each position point in the world plane coordinate system in the map coordinate system corresponding to the customized map are obtained according to the following formulas (3) and (4):

x’＝cWidth/x_b*x (3)

y’＝cHeight/y_b*y (4)

wherein x and y are coordinate values in the world plane coordinate system, and x 'and y' are coordinate values in the map coordinate system. If the third position information corresponding to the first position information is to be acquired, the third position information will be acquiredCoordinates (x) corresponding to the first position information_n,y_n) Substituting into equations (3) and (4) to obtain the coordinates (x)_n’,y_n') is the third location information of the user's location within the custom map. Similarly, if the fourth position information corresponding to the second position information is to be acquired, the coordinate (x) corresponding to the second position information is obtained_m,y_m) Substituting into equations (3) and (4) to obtain the coordinates (x)_m’,y_m') is the fourth location information of the target location in the custom map.
