Exemplary embodiments of the present application are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present application to facilitate understanding, and should be considered as merely exemplary. Accordingly, one of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Fig. 1 is a flowchart of an electronic map display method disclosed in an embodiment of the present application, where the embodiment may be adapted to dynamically select map elements in combination with current driving behavior of a user during navigation, and display personalized electronic maps (i.e. navigation maps) for different users. The method of the embodiment can be implemented by an electronic map display device, and the device can be implemented by software and/or hardware and can be integrated on any electronic device with computing capability, such as a server and the like. Display terminals for displaying map elements or displaying an electronic map include, but are not limited to, user terminals and vehicle-mounted devices such as smartphones, tablet computers, navigator, or car set terminals.
As shown in fig. 1, the method for displaying an electronic map disclosed in this embodiment may include:
s101, according to current driving data of a user, determining display requirements of the user on map elements.
The current driving data of the user refers to data associated with the current driving behavior of the user, and may be used to characterize the display requirement of the user on the map element on the electronic map, for example, may include, but not limited to: current driving speed, current driving oil consumption, current navigation route, current geographical environment and current face monitoring data of a user, and the like. The embodiment can determine the current display requirement of the user on the map element according to one data or the combination of at least two data in the current driving data.
The map element represents element information forming an electronic map, such as interest points, information of illegal monitoring points, traffic light information, map basic information and the like, wherein the interest points can be a building, a shop, a scenic spot or a bus station and the like, the map basic information is basic geographic information required by the electronic map, such as streets, bridges, buildings, rivers, mountains and the like, and the same object with different display parameters can also form different map elements, and the display parameters comprise colors, brightness, shapes, two-dimensional or three-dimensional structures, font sizes and the like.
Display requirements include, but are not limited to, user requirements for content such as the number of displays, display types, and/or display styles of map elements, for example, the display requirements can be divided into two categories: weakening the display of map elements (weakening the demand) and strengthening the display of map elements (strengthening the demand); weakening the display of map elements includes, but is not limited to, reducing the number of map element displays of a particular type, shrinking map element display icons and display text, reducing the variety of map element display styles, etc., based on a map element library; accordingly, the display of the enhanced map elements includes, but is not limited to, increasing the number of map element displays of a specific type, increasing map element display icons and display text, increasing the diversity of map element display styles, and the like based on the map element library. Wherein, while reducing the display quantity of the map elements of a specific type, the display quantity of the map elements of other types can be properly increased, and vice versa. Under different display requirements, the number, the type and/or the style of target map elements displayed by the display terminal are different, so that the running performance of the display terminal can be considered, and the performance loss is not large because a large number of map elements are always displayed.
By taking the example that the local equipment is a server, different display demand levels can be preset according to statistics and analysis of a large amount of driving data, each demand level corresponds to a map display strategy, map element information specifically displayed under each map display strategy can be flexibly configured in advance and support change, and the embodiment is not limited specifically; when the server interacts with the display terminal or the driving device, current driving data of the user are obtained, then the current demand level of the user is determined, and the current target map element to be displayed is determined according to the corresponding relation between the demand level and the map display strategy.
According to the method and the device for displaying the map elements, the display requirements of the users on the map elements are determined according to the current driving data of the users, the effect of determining different display requirements for different users is achieved, a foundation is laid for determining the target map elements to be displayed currently according to the display requirements, and the display of the electronic map in the navigation process is matched with the current actual requirements of the users.
S102, determining a target map element to be displayed currently according to the display requirement.
According to the display requirements of users in the navigation process, determining the current target map elements to be displayed from a map element library, wherein the target map elements are map elements matched with the current display requirements and comprise the matching of the number, the type, the display effect and the like of the elements, so that the final map display effect in the display terminal is updated or adjusted in time, the operation performance of the display terminal is considered, and the performance loss of the display terminal when the electronic map is displayed is reduced.
The method includes the steps that the current high-speed driving state or low-speed driving state of a user can be determined according to the current driving speed or driving oil consumption of the user, generally, in the high-speed driving state, the probability of the user viewing an electronic map is smaller, the display quantity of map elements can be reduced, the display brightness can be reduced, otherwise, in the low-speed driving state, the probability of the user viewing the electronic map is larger, the display quantity of map elements can be properly increased, and the display brightness can be properly adjusted higher; according to the current navigation route, whether the route is a historical familiar route of a user or not can be determined, if so, fewer map elements can be displayed, and if not, more map elements can be displayed so as to ensure map guiding effect; if the current geographical environment belongs to a commercial area, more interest points of shops such as restaurants, hotels and banks can be displayed, and if the current geographical environment belongs to a remote area, the display of the interest points can be reduced; according to the current face monitoring data of the user, whether the user pays attention to the display terminal or not, namely whether the user views the electronic map or not can be analyzed, if the user is determined to pay no attention to the display terminal within a certain time, namely the probability that the user views the electronic map currently is smaller, fewer map elements can be displayed, and otherwise, more map elements can be displayed.
For example, according to the current display requirements, based on a map element library, increasing or decreasing the number of specific interest points, violation monitoring point information and traffic light information in the electronic map; also for example, depending on the current display requirements, cell icons, 3D building icons, etc. carrying a particular ground tint are added or subtracted based on the map element library.
S103, the target map element is sent to a display terminal, wherein the display terminal is used for displaying the target map element.
After the display terminal acquires the target map element, the final electronic map can be displayed on a screen through rendering and drawing so as to be checked by a user. Taking the display terminal as a vehicle machine as an example, the vehicle machine receives the target map elements issued by the server, renders and draws the target map elements, and displays the vehicle machine map corresponding to the current user demand.
According to the technical scheme of the embodiment, the display requirement of the user on the map elements is determined according to the current driving data of the user, the current target map elements to be displayed are further determined, and finally the target map elements are sent to the display terminal, so that the technical effect of displaying the map elements for different users in a personalized manner is realized, and the problem of single map display mode in the existing scheme is solved; and through the selective display of the map elements, the operation performance of the display terminal is considered, the problem that the display terminal always displays a large number of map elements in the existing scheme, and the loss of the map display process is large is solved, the normal operation of other application programs except the map application in the display terminal is ensured, and the fluency and the stability of the display terminal are improved.
Fig. 2 is a flowchart of another electronic map display method disclosed in the embodiment of the present application, which is further optimized and expanded based on the above technical solution, and may be combined with the above various alternative embodiments. As shown in fig. 2, the method may include:
s201, identifying current driving data of a user, and if the current driving data comprises a current navigation route, matching the current navigation route in a historical navigation route of the user, and determining whether the user currently belongs to a acquaintance road driving mode.
The current navigation route represents a navigation route between the current position of the user and the destination position, which is displayed on the display terminal.
The local equipment can acquire current driving data of a user through interaction with the display terminal, when the current driving data are identified to comprise a current navigation route, ID information corresponding to the current driving data of the user, such as a frame number, a license plate number or an engine number, is determined, a historical navigation route corresponding to the user is determined from stored historical navigation routes according to the determined ID information, the current navigation route is matched in the historical navigation routes of the user, if the route similarity between the current navigation route and a certain historical navigation route is larger than a similarity threshold value, the matching is successful, and if the number of the historical navigation routes matched with the current navigation route is larger than a number threshold value, the current navigation route is determined to be a familiar route of the user, namely the user currently belongs to a acquainted route driving mode. The similarity threshold and the number threshold may be adaptively set, and the embodiment is not specifically limited.
In addition, the method of the embodiment can further comprise the following steps: the historical navigation routes of the user are counted and analyzed, and the normal routes of the user are determined in advance, so that when the navigation routes are matched, the navigation routes can be directly matched in the normal routes of the user, the matching efficiency is improved, and further the determining efficiency of the display requirements of the user is improved.
S202, according to a determination result of the current driving mode of the user, determining the display requirement of the user on the map element.
For example, if the current driving mode of the user belongs to the acquaintance driving mode, the user is familiar with the current navigation route, so that the display requirement of the user on the map elements is determined to be a weakening requirement, for example, the display quantity of the map elements can be reduced, the display icons and the display characters of the map elements can be reduced, the diversity of the display patterns of the map elements can be reduced, and the like based on the map element library. If the current driving mode of the user does not belong to the acquaintance driving mode, the current navigation route is unfamiliar to the user, so that the display requirement of the user on the map elements is determined to be an intensified requirement, for example, the display quantity of the map elements, the display icons and the display characters of the map elements, the diversity of the display patterns of the map elements and the like can be increased based on a map element library.
S203, determining a target map element to be displayed currently according to the display requirement.
For example, if the display requirement is that the display of the map elements is enhanced, increasing the number of interest points, violation monitoring point information and traffic light information displayed in the electronic map, such as increasing the number of hotels, gas stations, parking lots, speed measurement photographing, violation photographing and traffic lights in the electronic map; and/or displaying icons with larger graphic areas or fonts; and/or displaying icons carrying different ground colors, 3D icons and the like.
For example, if the display requirement is to weaken the display of the map element, the number of interest points, violation monitoring point information and traffic light information displayed in the electronic map is reduced, such as the number of hotels, gas stations, parking lots, speed measurement photographing, violation photographing and traffic lights in the electronic map is reduced; and/or displaying icons with smaller graphic areas or fonts; and/or displaying only a single color icon, 2D icon, etc.
S204, the target map element is sent to a display terminal, wherein the display terminal is used for displaying the target map element.
In this embodiment, whether the user currently belongs to the acquaintance driving mode or not is determined according to the current navigation route of the user, and the display requirements of the user on the map elements are determined respectively for the two situations that the user belongs to the acquaintance driving mode and the user does not belong to the acquaintance driving mode, so that different target map elements to be displayed are finally determined, the technical effect of individually displaying the map elements for different users is achieved, meanwhile, different target map elements are displayed in different driving modes, the operation performance of the display terminal is considered, the problem that the performance consumption of the display terminal is large due to the fact that more map elements are always displayed without distinction is solved, the normal operation of other application programs in the display terminal is guaranteed, and the smoothness and stability of the display terminal are further improved.
Fig. 3 is a flowchart of another electronic map display method disclosed in the embodiment of the present application, which is further optimized and expanded based on the above technical solution, and may be combined with the above various alternative embodiments. As shown in fig. 3, the method may include:
s301, identifying current driving data of a user, and if the current driving data comprises a current navigation route, determining a road type corresponding to the current navigation route.
Currently, road types may be classified into an extraurban road and an urban road according to a traveling vehicle speed on a road, wherein the extraurban road includes, but is not limited to, expressways, provinces, national roads, outer loops, and the like; urban roads include, but are not limited to, urban roads, accessory roads, and commercial street roads. Different road types may correspond to different map element display requirements.
S302, according to the road type, determining the display requirement of the user on the map element.
For example, if the road type is an off-road, the road condition is simple, the driving route is fixed, and the user needs to drive for a long time, so as to determine that the display requirement of the user on the map elements is a weakening requirement, that is, weakening the display of the map elements, for example, reducing the display quantity of the map elements, reducing the display icons and the display characters of the map elements, reducing the diversity of the display patterns of the map elements, and the like. If the road type is urban road, the road condition is complex and the driving route is changeable, so as to determine the display requirement of the user on the map elements as the strengthening requirement, i.e. strengthening the display of the map elements, such as increasing the display quantity of the map elements, increasing the display icons and the display characters of the map elements, and increasing the diversity of the display patterns of the map elements.
S303, determining a target map element to be displayed currently according to the display requirement.
For example, if the display requirement is that the display of the map elements is enhanced, increasing the number of interest points, violation monitoring point information and traffic light information displayed in the electronic map, such as increasing the number of hotels, gas stations, parking lots, speed measurement photographing, violation photographing and traffic lights in the electronic map; and/or displaying icons with larger graphic areas or fonts; and/or displaying icons carrying different ground colors, 3D icons and the like.
For example, if the display requirement is to weaken the display of the map element, the number of interest points, violation monitoring point information and traffic light information displayed in the electronic map is reduced, such as the number of hotels, gas stations, parking lots, speed measurement photographing, violation photographing and traffic lights in the electronic map is reduced; and/or displaying icons with smaller graphic areas or fonts; and/or displaying only a single color icon, 2D icon, etc.
S304, the target map element is sent to a display terminal, wherein the display terminal is used for displaying the target map element.
In this embodiment, the display requirements of users on map elements under different road types are respectively determined according to the road types corresponding to the current navigation route, and different current target map elements to be displayed are finally determined, so that the technical effect of individually displaying the map elements for different users is realized.
Fig. 4 is a flowchart of another electronic map display method disclosed in the embodiment of the present application, which is further optimized and expanded based on the above technical solution, and may be combined with the above various alternative embodiments. As shown in fig. 4, the method may include:
s401, identifying current driving data of a user, and if the current driving data comprises the current geographical environment, determining the region type of the current geographical environment, wherein map elements to be displayed under different region types are different.
The current geographical environment of the user can be determined according to the user positioning coordinates in the navigation process, for example, the current positioning coordinates of the user are matched in the electronic map, so that the current geographical environment of the user is determined. The region types of the geographic environment may be divided according to region functions, including but not limited to business regions, attraction regions, shopping regions, dining regions, and the like. The map elements displayed under each region type may be preset to form a display policy for the different region types.
S402, according to the region type, determining the display requirement of the user on the map element.
Under different region types, different map element display strategies can be configured in advance so as to display different map elements according to region type distinction, and the operation performance of the display terminal when displaying the map is considered. Different region types correspond to different user display requirements.
If the region type is a business region, determining that the business interest points in the map element are required to be enhanced by the user, and increasing the display quantity of the business interest points; meanwhile, the non-business interest points (other interest points except the business interest points) in the map element can be determined to be weakening requirements, and the display quantity of the non-business interest points can be reduced.
If the region type is the scenic spot region, determining that the scenic spot interest points in the map element are the strengthening requirements of the user, and increasing the display quantity of the scenic spot interest points; meanwhile, the method can also determine that the user has weakened requirements on the non-scenic spot interest points in the map elements, and can reduce the display quantity of the non-scenic spot interest points.
If the region type is a shopping region, determining that the shopping interest points in the map element are strengthening requirements of the user, and increasing the display quantity of the shopping interest points; meanwhile, the non-shopping interest points in the map elements can be determined to be weakening requirements of the user, and the display quantity of the non-shopping interest points can be reduced.
If the region type is a catering region, determining that the catering interest points in the map element are required to be intensified by the user, and increasing the display quantity of the catering interest points; meanwhile, the method can also determine that the non-catering interest points in the map elements are weakened requirements of users, and can reduce the display quantity of the non-catering interest points.
