The method of the present embodiment can be performed by an electronic map display device, which can be implemented in software and/or hardware, and can be any electronic computer with computing power, such as a server. Can be integrated into equipment. Display terminals for displaying map elements or displaying electronic maps include, but are not limited to, user terminals and in-vehicle equipment such as smartphones, tablets, navigators, or in-vehicle information communication terminals.

As shown in FIG. 1, the electronic map display method disclosed by this embodiment can include the following steps.

At S101, the user's display demand for map elements is determined based on the user's current driving data.

Therefore, the number of displayed map elements may be reduced, or the brightness of the display may be reduced. , the brightness of the display may be increased appropriately, and based on the current navigation route, it can be determined whether the route is a familiar route for the user's history, and if so , less map elements can be displayed, otherwise more map elements can be displayed, so as to ensure the guidance effect of the map, and the current geographical environment is a commercial area downtown. In some cases, it is possible to display more points of interest of shops such as restaurants, hotels, banks, etc., and if the current geographical environment is remote, the display of the points of interest can be reduced, and the current location of the user can be displayed. Based on the face monitoring data, it is possible to analyze whether or not the user is paying attention to the display terminal, that is, whether or not the user is browsing the electronic map. If it is determined not, ie if the probability that the user is currently viewing the electronic map is low, fewer map elements can be displayed, otherwise more map elements can be displayed.

For example, according to the current display demand, increase or decrease the number of specific points of interest, traffic violation monitoring point information and traffic light information in the electronic map based on the map element library, and for example, according to the current display demand, Increase or decrease cell icons, 3D building icons, etc. with specific background colors based on the map element library.

FIG. 5 is a flowchart of another electronic map display method disclosed by an embodiment of the present application, which is further optimized and expanded based on the above technical scheme and combined with each of the above selective embodiments. be able to. As shown in FIG. 5, the method may include the following steps.

In S501, recognizing current driving data of a user, and if the current driving data includes current face monitoring data, whether the user is paying attention to the display terminal based on the current face monitoring data. , wherein the current face monitoring data includes face angles and/or eye angles.

Current face monitoring data is used to determine whether the user is eyeing the display terminal. Here, the face angle can refer to the angle between the frontal orientation of the user's face and the normal direction of the display screen of the display terminal, and the eyeball angle refers to the direction of attention of the user and the display terminal. It can refer to the angle between the normal direction of the screen. For example, in the navigation process, the display terminal immediately monitors the user by calling the camera, and then transmits the monitoring image to the local device, and the local device uses any available image recognition technology to The user's eye angle is determined by determining the user's eye gaze direction using any available eye-tracking technology.

Exemplarily, if at least one of the user's face angle and eyeball angle is continuously greater than the corresponding angle threshold within a preset time, it is determined that the user is not currently paying attention to the display terminal. otherwise, it can be preset to determine that the user is currently looking at the display terminal. Here, angle threshold values corresponding to the face angle and the eyeball angle can be set adaptively, and are not specifically limited in this embodiment. The preset time means a specific time interval up to now, and the specific length of time can be set adaptively.

In S502, the user's display demand for map elements is determined based on the determination result of whether the user is paying attention to the display terminal.

If it is determined that the user is not currently paying attention to the display terminal, it indicates that the user is familiar with the current navigation route or the geographical environment in which the user is currently located, thereby weakening the user's display demand for map elements. For example, the number of displayed map elements can be reduced, the displayed icon and displayed characters of the map elements can be reduced, the variety of display styles of the map elements can be reduced, and so on. If it is determined that the user is currently looking at the display terminal, it indicates that the user is not familiar with the current navigation route or the geographical environment in which the user is currently located, thereby enhancing the user's display demand for map elements. For example, the number of displayed map elements can be increased, the number of display icons and characters displayed for map elements can be increased, the variety of display styles of map elements can be increased, and so on.

In S503, a target map element to be displayed is determined based on the display demand.

Target map elements that match the enhanced demand and the weakened demand are determined based on different map element display policies for the enhanced demand and the weakened demand, respectively.

At S504, the target map element is transmitted to a display terminal for displaying the target map element.

In this embodiment, face monitoring is performed on the user to determine whether the user is currently paying attention to the display terminal, and further to determine the user's display demand for map elements, so that different users can Realize the technical effect of displaying map elements in a unique way, weaken the display of map elements when the user is not currently paying attention to the display terminal, reduce the performance loss caused by map drawing on the display terminal, It ensures the normal operation of other application programs and improves the smoothness and stability of the display terminal.

In each of the above technical proposals, the target map elements determined based on the user's current display demand include the basic map elements essential for map display and the map elements that require specific display according to the display demand. The target map element may refer to only the map element that requires specific display in the display demand, in which case a person skilled in the art will understand the electronic map that is finally displayed on the display terminal. is the display effect of combining the target map element and the basic map element. Basic map elements refer to map elements that are essential for map display.

Also, the current navigation route, the geographic environment in which the user is currently located, and the user's current facial monitoring data may be used alone or at least as a basis for determining the user's current map element display needs. A combination of the two types of data may be used simultaneously as a basis for determining a user's current display needs for map elements, and there is no restriction on the order of use of each other. For example, matching the current navigation route with the user's historical navigation route, determining whether the user currently belongs to the familiar route driving mode, determining the road type corresponding to the current navigation route, and determining the user's current navigation route. Determining whether the user is paying attention to the display terminal, etc., based on the face monitoring data of , can also be used as a basis for determining the display demand for the current map element of the user. 2-5 illustrate examples of determining a user's current map element display needs based on driving data, which should not be understood as a specific limitation to the present embodiments. In practical application, the combination of different driving data can be used according to need to finally determine the user's current display demand for the map element.

FIG. 6 is a flow chart of another electronic map display method disclosed by an embodiment of the present application, which is further optimized and expanded based on the above technical solution and combined with each of the above selective embodiments. be able to. As shown in FIG. 6, the method can include the following steps.

In S601, the performance data of the display terminal is acquired, and the candidate map elements to be displayed at present are determined based on the performance data.

Here, the performance data of the display terminal, that is, the performance data of the central processing unit of the display terminal can include, for example, main frequency data, external frequency data, bus frequency data, frequency multiplication coefficient data, cache data, etc. It is not limited to these. The performance data of the display terminal can also reflect the occupancy of CPU resources of the display terminal. The local device obtains the performance data of the display terminal through interaction with the display terminal, and then determines the current display target candidate map elements based on the map element library according to the level of the performance data. So, when the electronic map is displayed on the current display terminal, it can be compatible with its own performance.

Selectably, the step of determining candidate map elements to be currently displayed on the basis of the performance data includes determining a map element to be currently displayed on the display terminal based on a correspondence relationship between the performance data and map element types. determining an element type; and determining said candidate map elements based on said map element type.

In this embodiment, the map elements in the electronic map may be classified into different types according to a preset classification policy, for example, the map element types are basic map elements, experience map elements and optimized map elements. including. Basic map elements can refer to elements that meet basic map display needs, including basic information and points of interest required for map display. can point to additional map elements for a particular scene, e.g., points of interest for a particular scene, and display experiential map elements compared to displaying only basic map elements. , the map display effect can be appropriately improved, and the user's experience of using the map can be enhanced. It is possible to point to a map element that suits the taste of the user, and display the optimized map element based on the display of the experience-based map element, thereby further improving the map display effect. As the display of different types of map elements increases, so does the performance loss of the display terminal. Each type of map element can be prioritized so that it is selected based on priority in the map element selection process. Here, the priority of the map elements may be set by the system or specified by the user, and is not specifically limited in this embodiment.

Illustratively, the local device can set corresponding performance data demand ranges for the basic map element, the experience map element and the optimized map element, respectively, according to the map display effect of the display terminal. For example, when displaying basic map elements, the range of demand for the necessary performance data is the lowest, occupying the CPU resources of the display terminal is the smallest, and when displaying experiential map elements, it is the next best. When displaying a modified map element, the necessary performance data demand range is the highest, and the occupation of the CPU resource of the display terminal is also the highest. After the local device obtains the performance data, match the performance data with the preset performance data range, determine the performance data range in which the performance data exists, further determine the corresponding map element type, and then , all or some of the map elements of the map element type can be determined as candidate map elements.

By determining the candidate map elements that the display terminal can currently display based on the correspondence between the display terminal performance data and the map element types, it is possible to show different map display effects on the premise that the terminal performance can support it. can be guaranteed, so that after obtaining the target map element by subsequently adjusting the candidate map elements according to the user's display needs, the display of the target map element is still within the capabilities of the display terminal. It is in.

At S602, the user's display needs for map elements are determined based on the user's current driving data.

In S603, the candidate map elements are adjusted and the target map elements are determined based on the display demand.

Based on the user's current display demand for map elements, the candidate map elements are adjusted, specifically, based on the candidate map elements, the map elements are increased or decreased, and the target map elements are determined. For example, if the current candidate map element is a basic map element, the experience map element and the optimized map element can be increased appropriately according to the display demand, which will excessively increase the performance loss of the display terminal. If the current candidate map elements are optimized map elements, the optimized map elements are appropriately reduced according to the display demand, and the display terminal performance loss in the map display process can be reduced.

At S604, the target map element is transmitted to a display terminal for displaying the target map element.
