In the related art, when rendering road information, a road network of a base map is usually displayed first to present information such as a geometric shape of the road network. In addition to the base map network, if it is necessary to display other road information (for example, road condition information and navigation earthworm lines), it is necessary to further issue shape data corresponding to the road condition information and the navigation earthworm lines and render the shape data. In such a method, a large amount of data needs to be acquired from the server, and drawing needs to be performed a plurality of times, and the drawn shape and the road network base map have a poor degree of fitting and are unstable.

In order to solve the problem, the road network base map is rendered, the road condition data are obtained according to the road identifications of the target roads in the road network base map, and then rendering styles of the roads are adjusted based on the road condition data, so that the road condition information can be displayed on the basis of the road network base map. By the method, when the road condition data of the road is obtained, only the information directly related to the road condition can be obtained without obtaining the shape information corresponding to the road condition data, the data volume needing to be obtained is reduced, and the rendering style of the road is modified to present the road condition information, so that the consumption of computing resources caused by rendering and drawing work can be reduced.

The system 100 of fig. 1 may be configured and operated in various ways to enable application of the various methods and apparatus described in accordance with the present disclosure.

According to an aspect of the present disclosure, there is provided a road information display method. As shown in fig. 2, the method includes: step S201, rendering a road network base map, wherein the road network base map comprises a plurality of target roads, and the rendering style of each target road in the plurality of target roads is a first rendering style corresponding to the target road and is provided with a road identifier corresponding to the target road; and step S202, responding to the received road condition information display request, aiming at each target road in the multiple target roads, based on the road condition data of the target road, adjusting the rendering style of the target road to be a second rendering style, wherein the road condition data is obtained from the server based on the road identification of the corresponding target road, and the second rendering style represents the road condition information of the corresponding target road.

Therefore, the road condition information can be displayed on the basis of the road network base map by rendering the road network base map, acquiring the road condition data according to the road identifications of the target roads in the road network base map and then adjusting the rendering patterns of the roads based on the road condition data. By the method, when the road condition data of the road is obtained, only the information directly related to the road condition can be obtained without obtaining the shape information corresponding to the road condition data, the data volume needing to be obtained is reduced, and the rendering style of the road is modified to present the road condition information, so that the consumption of computing resources caused by rendering and drawing work can be reduced.

According to some embodiments, the method of the present disclosure may be used for various types of software or services related to electronic maps. In an electronic map, a road network base map (or a base map network) is the bottommost image in a plurality of map layers, and constitutes a basic framework of the map. Different objects, such as roads, intersections, bridges, buildings, etc., can be represented in different ways (e.g., different shapes, colors, etc.) in the road network base map.

The data of the road network base map can be periodically or aperiodically acquired from the server, or can be stored by the client. The data of the road network base map can be transmitted, stored and rendered in a grid unit. In an exemplary embodiment, a mesh with a size of 512 meters × 512 meters may be used as a basic constituent unit of the road network base graph. It is understood that the mesh in the road network base map may have other sizes. In the data corresponding to each mesh, data related to roads within the mesh, such as road Identification (ID), shape data, various style information, and the like, may be included. By rendering the mesh, elements such as roads within the mesh may be presented in the display area of the client.

The data of the road network base map can be different under different scales. In one exemplary embodiment, at the first resolution, the size of the grid in the road network subgraph graph is 512 meters by 512 meters; at a second resolution different from the first resolution, the size of the mesh in the road network roadmap is 1024 meters by 1024 meters. Thus, meshes at different scales may include different content, but it is noted that the same object (e.g., the same road) has the same identification in different meshes. That is, the same road, although possibly having different shapes in the meshes at different scales, has the same road sign in both of the meshes.

In some embodiments, the target road may span multiple adjacent meshes, and data related to the target road, such as an ID, a style, etc., may be stored in each mesh. If the rendering style of the target road is adjusted in one mesh, the adjustment needs to be performed simultaneously in all meshes.

The target road may be all the roads in the road network base map, or may be a part of the roads. In some embodiments, to save the amount of data retrieved from the server, each of the plurality of target roads is displayed at least partially in the display area of the client. That is, the target road is a road displayed in a display area (e.g., a map interface in an application) of the client. In some embodiments, after detecting the operation of swiping, zooming in, zooming out, etc. on the map, all roads in the display area after the operation may be used as target roads, and the road condition information may be displayed. It can be understood that, since the same road corresponds to the same ID at different scales, after the map is subjected to the above operations, part of the road condition information of the target road displayed in the display area of the client may be cached on the client, and at this time, only the road condition information of another part of the target road for which the road condition information has not been acquired may be acquired, so as to further reduce the amount of data to be acquired.

According to some embodiments, the road network base map is obtained by rendering shape data of each of a plurality of original roads in the original road network data. When the base graph road network is compiled and rendered, due to the existence of the up-down row and the road junction surface, or due to other reasons, part of the original road can be cut, merged or merged, so that the finally rendered road and the original road are not identical. In the process, the ID of part of the original road may be lost, and since the actually rendered road may not exist on the server, the traffic information of the road cannot be directly obtained from the server. Therefore, the IDs of the original roads can be recorded first during compiling and rendering, so that the IDs of the original roads corresponding to the actual rendered roads can be found when the road condition information of the actual rendered roads is obtained, and the corresponding road condition information can be successfully obtained. In some embodiments, each of the plurality of target roads may be obtained by performing at least one of retaining, cutting, merging, or merging on at least a portion of the plurality of original roads, the road identifier of the target road may include a road identifier of the corresponding at least a portion of the original roads, the road condition data of the target road may be obtained from the server based on the road identifier of the corresponding at least a portion of the original roads, and the second rendering style of the target road may characterize the road condition information of the corresponding at least a portion of the original roads.

In some embodiments, the rendering style of the road may include a variety of different settings, such as fill color, transparency, edge color, whether to fade, and so forth. The first rendering style, the second rendering style, and hereinafter, the third rendering style may be set by those skilled in the art as needed so that they can reflect various types of information related to a road. In one exemplary embodiment, congestion may be represented by red, clear by blue, and the earthworm line navigated by green.

According to some embodiments, the first target road and the second target road of the plurality of target roads may be obtained by cutting a first original road of the plurality of original roads, and each of the first target road and the second target road may be obtained by rendering based on shape data of the first original road. The road marking of the first target road and the road marking of the second target road may each comprise a road marking of the first original road.

In some embodiments, the first target road may correspond to a first portion of the first original road, and the second target road may correspond to a second portion of the first original road, so that the first target road may be rendered based on the shape data of the first portion of the first original road, and the second target road may be rendered based on the shape data of the second portion of the first original road, so that the finally rendered first target road and second original road may correctly embody the shape information of the first original road. It is understood that a junction node may be rendered at the junction between the first target road and the second target road to make the junction transition between the first target road and the second target road more natural and avoid gaps. The rendering style of the connection node may be the same as the first target road, the same as the second target road, or other configurations, which are not limited herein.

In some embodiments, as shown in fig. 3A, the original road L1 is cut into the target roads L11 and L12, and the IDs of the target roads L11 and L12 may be recorded as L11: L1 and L12: L1, respectively.

According to some embodiments, the second rendering style corresponding to the first target road and the second rendering style corresponding to the second target road may both represent road condition information of the first original road. Therefore, the first target road and the second target road can both reflect correct road condition information.

According to some embodiments, the third target road of the plurality of target roads may be obtained by merging a second original road and a third original road of the plurality of original roads, and the third target road may be obtained by rendering based on shape data of the second original road and shape data of the third original road. The link identification of the third target link may include a link identification of the second original link and a link identification of the third original link.

In some embodiments, as shown in fig. 3B, the original roads L1 and L2 are merged into the target road L12, then the target road L12 may include a first part corresponding to L1 and a second part corresponding to L2, and the ID of the first part of L12 may be recorded as L1: L12, and the ID of the second part of L12 may be recorded as L2: L12.

According to some embodiments, the third target road may include a first portion corresponding to the second original road and a second portion corresponding to the third original road. The second rendering pattern corresponding to the first portion of the third target road may represent traffic information of the second original road, and the second rendering pattern corresponding to the second portion of the third target road may represent traffic information of the third original road. Therefore, the third target road can embody the correct road condition information. It will be appreciated that, in rendering the third target road, a junction node may be rendered at the junction between the first and second portions of the third target road to make the junction transition between the first and second portions of the third target road more natural and avoid gaps. The rendering style of the connection node may be the same as that of the third target road, or may be set in other manners, which is not limited herein.

According to some embodiments, the fourth target road of the plurality of target roads may be obtained by merging the fourth original road of the plurality of original roads to the fifth original road, and the fourth target road may be obtained by rendering based on the shape data of the fifth original road. The road identification of the fourth target road may include a road identification of the fourth original road and a road identification of the fifth original road.

In some embodiments, as shown in fig. 3C, the original road L1 is merged into the original/target road L2, then the ID discarded by L1 may be attributed into L2, and the ID of L2 may be recorded as L1, L2.

According to some embodiments, the second rendering style corresponding to the fourth target road may represent road condition information of the fifth original road. Therefore, the fourth target road can embody the correct road condition information.

According to some embodiments, as shown in fig. 4, the road information display method may further include: step S403, in response to receiving the navigation request, determining respective road identifiers of a plurality of navigation roads and a plurality of navigation roads; step S404, determining at least one part of target roads consistent with a plurality of navigation roads in the plurality of target roads based on the road identification; and step S405, adjusting the rendering style of at least one part of the target road into a third rendering style, wherein the third rendering style represents the navigation information of the corresponding target road. It is understood that the operations of step S401 to step S402 in fig. 4 are similar to the operations of step S201 to step S202 in fig. 2, and are not described herein again. Therefore, the navigation earthworm line is displayed in a rendering style adjusting mode, so that the data volume required to be acquired is further reduced, and the navigation earthworm line can be perfectly attached to the base map.

When the navigation initiates planning, a list of road IDs that a user needs to pass through can be sent to an engine end responsible for rendering and drawing, and after the engine receives the IDs, the corresponding road network information is found in a map area range (for example, a display area of a client), and the navigation information can be displayed by directly changing the rendering style of the road, similar to the display mode of the road condition information. It is understood that a person skilled in the art may set the corresponding third rendering style by himself or herself to implement the presentation of the navigation information. In some embodiments, some connection nodes are further included between the navigation roads, for example, intersections, and the rendering styles of these connection nodes may be modified according to the actual conditions of the navigation roads connected thereto, so that the finally obtained rendering result can accurately embody the navigation information. In an exemplary embodiment, roads are connected to the intersection a in four directions, namely, east, west, south and north, wherein the road m on the west side and the road n on the south side of the intersection a belong to navigation roads, and the rendering style of the intersection a can be modified so that the road m and the road n are connected through earthworm lines.

According to some embodiments, as shown in fig. 4, the road information display method further includes: step S406, responding to the received query request, and determining a road to be queried corresponding to the query request in the plurality of target roads; and step S407, displaying a query result corresponding to the road to be queried, wherein the query result is obtained from the server based on the road identification of the road to be queried. Therefore, after receiving the query request, the corresponding road to be queried can be determined, and then the corresponding query result can be obtained based on the ID of the road to be queried, such as restaurants around the road, gas stations, hospitals, entertainment facilities and the like.

According to another aspect of the present disclosure, a road information display device is also disclosed. As shown in fig. 5, the apparatus 500 includes: a rendering unit 510 configured to render a road network base map, wherein the road network base map comprises a plurality of target roads, and a rendering style of each of the plurality of target roads is a first rendering style corresponding to the target road and has a road identifier corresponding to the target road; and a first adjusting unit 520 configured to adjust, for each of a plurality of target roads, the rendering pattern of the target road to a second rendering pattern based on the road condition data of the target road, in response to receiving the road condition information display request, wherein the road condition data is obtained from the server based on the road identifier of the corresponding target road, and the second rendering pattern represents the road condition information of the corresponding target road. It is understood that operations of the units 510 to 520 in the apparatus 500 are similar to those of the steps S201 to S202 in fig. 2, and are not repeated herein.
