FIELD OF THE TECHNOLOGY
The present disclosure belongs to the field of information technologies, and in particular, to a route information displaying method and apparatus.
BACKGROUND OF THE DISCLOSURE
By combining electronic map technologies and satellite positioning systems, an intelligent terminal can record a route through which a user drives a car; and display the recorded route at a corresponding position of an electronic map, for the user to view the route conveniently.
However, an electronic map interface itself already includes abundant map information and has little space that can be used to display additional information; and therefore, currently, only a traveling track of the user can be marked in the electronic map; and traveling information related to the traveling track can be further viewed only by loading a new display page, or loading a floating window at a corresponding position of the traveling track. As a result, electronic map information and detailed traveling information cannot be comprehensively displayed simultaneously, which reduces the information acquisition efficiency.

DESCRIPTION OF EMBODIMENTS
In order to make the objectives, technical solutions, and advantages of the present disclosure more comprehensible, the present disclosure is described in further detail below with reference to accompanying drawings and embodiments. It should be understood that, the specific embodiments described herein are merely used to explain the present disclosure, but not intended to limit the present disclosure.
In the embodiments of the present invention, the amount of route information presented in an electronic map is expanded in a three-dimensional displaying manner, so as to comprehensively display detailed route information in the electronic map. Compared with a manner of displaying detailed route information by loading a new page or loading a floating window, the route information acquisition efficiency is effectively improved in the embodiments of the present invention.
FIG. 1 shows an implementation procedure of a route information displaying method according to an embodiment of the present invention. In this embodiment of the present invention, a route includes, but is not limited to, a route that a user passes through by walking, riding, driving, and the like while carrying a mobile terminal; and route information includes, but is not limited to, location information related to the route, information about a speed of travelling in the route, road speed limit information, road congestion information, and the like. The implementation procedure of FIG. 1 is described in detail as follows.
S101: Creating a three-dimensional coordinate system, and load an electronic map in the XY plane of the three-dimensional coordinate system.
In this embodiment, the three-dimensional coordinate system is created, so that the route information is displayed in a three-dimensional space displaying manner. In addition, after the three-dimensional coordinate system is created, the electronic map is loaded in the XY plane of the three-dimensional coordinate system, so that any location in the electronic map is represented by coordinates (x, y) in the XY plane or (x, y, a) in the three-dimensional coordinate system, where x and y are variables changing based on the real-time location, and a is a constant that can be pre-configured. In this case, the Z axis perpendicular to the XY plane is used to represent real-time speeds of the mobile terminal, and a value, on the Z axis, corresponding to the coordinates (x, y) can be used to represent a real-time speed of the mobile terminal when the mobile terminal passes through a location (x, y) in the electronic map.
S102: Acquiring, by using a satellite positioning system, a real-time location of a mobile terminal and a real-time speed of the mobile terminal corresponding to the real-time location.
The satellite positioning system includes, but is not limited to, the global positioning system (GPS) of America, the Galileo satellite positioning system of the European Union, the GLONASS system of Russia, and the BeiDou system of China.
In this embodiment, a signal receiver built in the mobile terminal is used to capture a tracked satellite signal to acquire related observation parameters of an observation point (namely, the mobile terminal); and a processor of the mobile terminal is further used to calculate the observation parameters to obtain information such as a longitude, a latitude, a height, a speed of a geographical location in which the mobile terminal is currently located, so as to acquire a current location of the mobile terminal and a real-time speed, of the mobile terminal, corresponding to the current location.
For example, the user drives from a location A (where a longitude is 116.3078667535, and a latitude is 39.9845898438) to a location B (where a longitude is 116.2170274523, and a latitude is 40.0772365994) at 12: 27: 17 on Nov. 2, 2013 while carrying a mobile terminal. In this case, as shown in FIG. 2A, when the user arrives at a location C at 12: 59: 24 on Nov. 2, 2013, the mobile terminal acquires a real-time location of the mobile terminal as follows: a longitude is 116.2443253581, a latitude is 40.0732606337, and a real-time speed corresponding to the real-time location is 30.76 km/h; and as shown in FIG. 2B, after 1 second, namely, at 12: 59: 25 on Nov. 2, 2013, the user arrives at a location D, and the mobile terminal acquires a real-time location of the mobile terminal as follows: a longitude is 116.2442865668, a latitude is 40.0733094618, and a real-time speed corresponding to the real-time location is 23.76 km/h. In this example, a real-time location and a real-time speed corresponding to the real-time location are associated with a same time point.
S103: Drawing both a moving route and a speed curve of the mobile terminal in the three-dimensional coordinate system according to the acquired real-time location and the acquired real-time speed, where the real-time location of the mobile terminal is represented in the XY plane of the three-dimensional coordinate system, and the real-time speed of the mobile terminal is represented on the Z axis of the three-dimensional coordinate system. In other words, coordinate (x, y, z) in the three-dimensional coordinate system may represent the real-time speed of the mobile terminal, where the values of variables x and y indicate the real-time location, and the value of variable z is proportional to the real-time speed corresponding to the real-time location. In some embodiments, the real-time speed may be represented by (x+m, y+n, z), where m and n are constants that can be predefined.
For the acquired real-time locations of the mobile terminal, position points are drawn at corresponding coordinate positions of the XY plane or a plane parallel with the XY plane according to longitude and latitude data representing the real-time locations, so as to draw the moving route of the mobile terminal in real time (e.g., by connecting neighboring data points of the real-time locations).
For the acquired real-time speeds, of the mobile terminal, corresponding to the real-time locations of the mobile terminal, drawing is performed one data point by one data point in the three-dimensional coordinate system created in S101, so as to draw a three-dimensional speed curve of the mobile terminal in real time (e.g., by connecting neighboring data points of the real-time locations), where the drawn speed curve and moving route have a one-to-one correspondence in each real-time location.
In specific implementation, the moving route and the speed curve of the mobile terminal may be separately drawn in different colors, and corresponding color block legends are used to separately indicate the colors for representing the moving route and the speed curve, so as to distinguish the moving route and the speed curve that appear in same display space in an intuitive and simple way, thereby improving the route information acquisition efficiency. In some embodiments, the Z-axis may be displayed on a side of the screen with legend marks indicating reference speeds (e.g. every 20 km/h from 20 to 140 km/h).
Further, a color in which each point in the speed curve is drawn may further be determined according to a value, of the point, on the Z axis. For example, when a real-time speed of the mobile terminal is greater than 60 km/h, a point corresponding to the real-time speed is drawn in red; and when a real-time speed of the mobile terminal is less than 10 km/h, a point corresponding to the real-time speed is drawn in blue. Different colors are used to indicate a speed change condition in the speed curve, which increases an information amount of displayed route information.
Finally, by using the embodiment shown in FIG. 1, a schematic diagram of the route information displayed on the electronic map is shown in FIG. 3. It can be seen that by adding a dimension of route information display space, both a moving route 31 and a speed curve 32 of the mobile terminal can be displayed in a same display page; and route information display can be simply combined with the electronic map, so that display information of the electronic map itself is not covered as much as possible, thereby maximizing information capacity of the display page.
Further, as an embodiment of the present invention, as shown in FIG. 4, after S103, the method may further include the following steps.
S104: Locating at least one of a speed peak and a speed valley in the speed curve.
The speed peak (namely, a maximum value of the real-time speed) and/or the speed valley (namely, a minimum value of the real-time speed) of the mobile terminal in a moving process may be located in the drawn speed curve according to the real-speed of the mobile terminal collected in real time in S102.
S105: Mark the located speed peak and/or speed valley in the speed curve.
Specifically, speed values of the speed peak and/or the speed valley may be marked by adding floating labels to positions at which the speed peak and/or the speed valley are located, or may also be marked by using drawn points of different shapes (for example, a circle and a triangle) or drawn points of highlighted colors at positions at which the speed peak and/or the speed valley are located. A specific marking manner herein is not intended to limit the present disclosure.
Further, for an application scenario in which the route is a route that the user passes through by driving while carrying the mobile terminal, as an embodiment of the present invention, as shown in FIG. 5, after S103, the method may further include the following steps.
S106: Acquiring speed limit information of the moving route.
On a city road, an expressway, or a high-speed road, basically, each traffic road is provided with corresponding speed limit information. For example, a maximum driving speed allowed on a city high-speed road usually is not higher than 80 kilometers/hour and is not lower than 40 kilometers/hour, and a maximum driving speed allowed on an expressway usually is not higher than 120 kilometers/hour and is not lower than 80 kilometers/hour. Therefore, before S106, speed limit information of all traffic roads may be collected on-site or from a related information website of a traffic administration department in advance, and stored in a server; and when the moving route of the mobile terminal is determined, speed limit information of a traffic road matching the moving route is invoked and obtained by communicating with the server.
S107: Drawing a speed limit curve of the moving route in the three-dimensional coordinate system according to the acquired speed limit information.
In this embodiment, the speed limit curve of the moving route is drawn in the three-dimensional coordinate system according to the acquired speed limit information of the moving route based on the same method of drawing the speed curve in S103, and when a traffic administration department stipulates a maximum speed and a minimum speed allowed on a same road, drawn speed limit curves include a maximum speed limit curve and a minimum speed limit curve. Similarly, the speed limit curve may also be drawn in a different color to distinguish from the moving route and the speed curve of the mobile terminal.
Further, based on the embodiment shown in FIG. 5, by comparing a real-time speed corresponding to each real-time location and the speed limit information, a part in the speed curve which exceeds the speed limit curve is determined; and the part in the speed curve which exceeds the speed limit curve is marked.
That is, values of the speed curve and the speed limit curve, on the Z axis, in a same coordinate location on the XY plane of the three-dimensional coordinate system are compared; and if the value of the speed curve in the coordinate location is greater than the value of the speed limit curve in the coordinate location, this part of the speed curve is marked to confirm that in this segment of the moving route, a real-time speed of the mobile terminal exceeds a speed limit range of this segment of the moving route.
Similarly, an overspeed part in the speed curve may be marked by adding floating labels, or by using drawn points of different shapes (for example, a circle and a triangle) or drawn points of highlighted colors. A specific marking manner herein is not intended to limit the present disclosure.
In this embodiment, by marking the overspeed part in the speed curve, the user can quickly learn an overspeed road segment in a drive route of the user when viewing the route information; and whether overspeed occurs in the drive route is determined without querying a speed limit condition in a road segment and comparing speeds, which improves the route information acquisition efficiency.
Further, as an embodiment of the present invention, as shown in FIG. 6, after S103, the method may further include the following steps.
S108: Acquiring an average speed of other mobile terminals in the moving route.
In this embodiment, a related application client for displaying the route information can communicate with a background server of the related application client, and report acquired real-time speed information of a current mobile terminal in the moving route to the server. After collecting real-time speed data reported by multiple mobile terminals, the server calculates an average speed of the mobile terminals at each real-time location, and feeds back calculated average speed data to the application client.
S109: Drawing an average speed curve in the three-dimensional coordinate system.
According to the average speed data fed back by the server, the average speed curve is drawn in the three-dimensional coordinate system based on the same method of drawing the speed curve in S103. Similarly, the average speed curve may also be drawn in a different color to distinguish from the moving route and the speed curve of the mobile terminal.
Based on the embodiment of the present invention shown in FIG. 6, it can be known that the application client may also acquire an average speed of a specific mobile terminal in a same moving route by communicating with the background server or communicating with the specific mobile terminal. This function may be combined with a friend function of a network community; and in addition to acquiring an average traveling speed of multiple mobile terminals in the moving route in this manner, the user may also acquire a traveling speed, of a friend of the user in a network community, in this moving route. The foregoing route information is all displayed in an electronic map by using a three-dimensional curve; and in this way, simple combination with the electronic map is implemented, and display information of the electronic map itself is not covered as much as possible, thereby maximizing information capacity of a display page.

The mobile phone 800 may obtain information about the locations and the speeds corresponding to the specific time period or the specific area from the local storage or from the background server. According to the obtained information, the disclosed method may be implemented by the processor 880 to present the moving route, the speed curve and other related information of the specific time period or specific area.
In the embodiments of the present invention, a displayed information amount of route information in an electronic map is expanded in a three-dimensional space displaying manner, so as to comprehensively display detailed route information in the electronic map. Compared with a manner of displaying detailed route information by loading a new page or loading a floating window, the route information acquisition efficiency is effectively improved in the embodiments of the present invention.
The foregoing descriptions are merely preferred embodiments of the present invention, but are not intended to limit the present disclosure. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present disclosure shall fall within the protection scope of the present disclosure.
