[0037] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0038] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0039] The map loading method, system, medium, and apparatus of the present invention provide a novel map loading method that can be applied to in-vehicle displays or handheld terminals, has a wide range of applications, can adapt to various environments, and improves user experience.

[0040] like Figure 1 As shown, in one embodiment, the map loading method of the present invention includes the following steps:

[0041] Step S11: Identify the target area.

[0042] Step S12: Obtain the display area based on the target range to display the map;

[0043] Step S13: Obtain map switching information to extract and display the corresponding map based on the preset index.

[0044] Specifically, touch screen information and / or voice information are acquired to identify the target range. For example, the target range can be obtained based on the touch screen information of the user's touch screen on the vehicle display or the voice information input by the user. The target range includes target points and target areas. The target range obtained based on the touch screen information can be a rectangle that selects the smallest area of ​​all touch screen points, wherein the rectangle is a rectangle with the same proportion as the current display surface, or it can be a circle that selects the smallest area of ​​all touch screen points. The target range obtained based on the voice information is obtained by performing text recognition and keyword extraction based on the voice information. For example, if "I want to go to Plaza A" is taken, then "Plaza A" is taken as the center point of the target range to obtain the target range.

[0045] Furthermore, a display area is obtained based on the target range to display the map, specifically, as follows: Figure 2 As shown, the display area is a region of corresponding level loaded based on the latitude and longitude of the target point within the target range. The corresponding level of the region includes city level, district level, county level, etc. The region level is loaded based on the latitude and longitude of the target point. For example, if the latitude and longitude span of the target point within the target range is higher than the district or county level, it is displayed as a city level map. Conversely, if the latitude and longitude span of the target point is within the district or county level, a map of the corresponding level is displayed. Points of interest on the map are displayed based on a preset display type. When displaying the map, [the following options are available]. The map area is used to display points of interest according to the display type, which includes "gas stations, hotels, restaurants, convenience stores, etc." Preferably, the points of interest are displayed during the map loading process, that is, they are displayed while loading. For example, if the voice information is "display restaurants within 200 meters of Plaza A", then the target area is centered on "Plaza A", with a radius of "200 meters", and "restaurants" are displayed as the points of interest. Every "50" meters, the restaurants in the corresponding road segment are displayed until all the "restaurants" in the target area are displayed.

[0046] Furthermore, obtain map switching information, such as Figure 3As shown, the map is extracted and displayed according to a preset index. Touch screen gestures and / or voice information are recognized to obtain map switching information. Specifically, taking a vehicle display screen as an example, the largest prefecture-level city unit within the screen area swiped by the finger is the current page index, the second largest display area is the next page index, and so on, with the third, fourth, and so on. Swiping forward to zoom out and swiping backward to zoom out is used as a map flipping mode, and the page flipping speed is controlled based on the loading speed. When flipping, the points of interest have been loaded. Preferably, when flipping the map, the user's three-finger operation can be recognized as the starting action for flipping, or a page flipping button can be set to flip the page.

[0047] Specifically, the method further includes the following steps:

[0048] Get the defined regions of the touchscreen;

[0049] The corresponding visible area is presented based on the defined regions.

[0050] Specifically, taking an in-vehicle display screen as an example, for areas of the same level, when a user moves the map horizontally at the same level, the corresponding visible area can be obtained by displaying the area divided by the touch screen. For example, the area is obtained by recognizing the user's two-finger or one-finger operation. Based on the visible area, the points of interest are dynamically displayed according to user preferences based on big data analysis. If no settings are specified, the corresponding points of interest can be determined and displayed based on the results of the user's big data analysis preferences. For example, if a user's points of interest obtained from big data analysis are "restaurants", then "restaurants" will be displayed first as the points of interest during map display.

[0051] It is worth mentioning that, in another embodiment of the invention, taking a user jumping from a provincial-level region to a county-level region as an example, for instance, if the user is traveling from a first-tier city across provinces to return home, the route can be loaded in a page-turning manner when the map is displayed. During the route layout process, audio accompanying the page-turning is loaded synchronously. In addition, when displaying, the starting point can be displayed on one side and the destination point on the other side, and points of interest can be loaded based on the two different points. The points of interest within the first range of the starting point can be "gas stations", and the points of interest within the second range of the destination point can be "restaurants". The first range can be five kilometers, and the second range can be two kilometers.

[0052] like Figure 4As shown, in one embodiment of the invention, the map loading system of the present invention includes an identification module 41, a display module 42, and an acquisition module 43; the identification module is used to identify a target range; the display module is used to obtain a display area based on the target range to display the map; the acquisition module is used to acquire map switching information to extract the corresponding map for display according to a preset index.

[0053] It should be noted that the structure and principle of the identification module 41, the display module 42 and the acquisition module 43 correspond one-to-one with the steps in the map loading method described above, so they will not be repeated here.

[0054] It should be noted that the division of the various modules in the above system is merely a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, these modules can be implemented entirely in software through processing element calls; they can be fully implemented in hardware; or some modules can be implemented by processing element calls to software, while others are implemented in hardware. For example, a module can be a separate processing element, or it can be integrated into a chip in the aforementioned device. Alternatively, it can be stored as program code in the memory of the aforementioned device, and its function can be called and executed by a processing element of the device. The implementation of other modules is similar. Moreover, these modules can be fully or partially integrated together, or they can be implemented independently. The processing element mentioned here can be an integrated circuit with signal processing capabilities. In the implementation process, the steps of the above method or the various modules can be completed through integrated logic circuits in the hardware of the processor element or through software instructions.

[0055] For example, these modules can be one or more integrated circuits configured to implement the above methods, such as one or more Application Specific Integrated Circuits (ASICs), one or more Microprocessors (MPUs), or one or more Field Programmable Gate Arrays (FPGAs). As another example, when a module is implemented using processing element scheduler code, the processing element can be a general-purpose processor, such as a Central Processing Unit (CPU) or other processor capable of calling program code. Furthermore, these modules can be integrated together to form a system-on-a-chip (SOC).
