However, the inventor finds that when a navigation path passes through areas spatially belonging to different floors, the navigation path is usually displayed completely in one interface at one time, which may cause that the displayed navigation routes are easily mutually overlapped, so that the navigation path and the navigation path seen by a user are different in actual conditions, resulting in poor user experience.
In view of the above problem, in this embodiment, a route display method is proposed, which first determines a target floor where a target object is located, and then renders a navigation sub-route passing through the target floor in a map layer corresponding to the target floor. According to the technical scheme, the rendering and display of the navigation path data in different floors are realized, so that the condition that the navigation paths of multiple floors are mutually overlapped when the navigation is performed on the paths in the places with multiple floors such as a multi-floor parking lot is avoided, the consistency of the navigation paths seen by a user and the actual navigation paths is ensured, the path navigation effect is improved, and the use experience of the user is improved.

In an embodiment of the present disclosure, the navigation path data refers to navigation path data within a certain target area. The target area refers to an area which exists in the user navigation path, is possibly used as a path area in the user navigation path, is also possible to be used as a starting point area or a destination area in the user navigation path, and has a two-layer or multi-layer structure. For example, if the target area is a parking lot with a multi-layer structure, the navigation path data is the navigation path data in the parking lot. Of course, the overall navigation path data of a certain target object may not only include the navigation path data of the target area, but also include the navigation path data in other areas.

In the navigation path data, the navigation path sub-data having the same floor identifier, that is, the navigation path sub-data corresponding to the same floor of the target area may exist in plural, and the navigation path sub-data having the same floor identifier are different from each other but have a certain path sequence therebetween, so that the navigation sub-paths which are divided by floors and respectively correspond to different floors can be obtained based on the navigation path data. The floor identification refers to identification information for identifying the target area floor distinctively, such as the target area floor ID, and further, the floor identification may further include target area identification information to identify the target area and the target area floor respectively.
In an embodiment of the present disclosure, the target object refers to an object, such as a pedestrian, a bicycle, a vehicle, a robot, a mobile resource, and the like, traveling based on the received navigation path data using a navigation service.
In view of the fact that the target object enters the target area from the outside of the target area, in the above embodiment, first, navigation path data within the target area is obtained, and a navigation sub-path segmented by floors is obtained based on the navigation path data; then, determining the target floor where the target object is located after entering the target area, for example, some target areas are parking lots including an above-ground level 1 to an underground level 2, when the target object enters the parking lots from the above-ground level 1, the above-ground level 1 is reached first, and some target areas are underground parking lots including an underground level 1 to an underground level 2, when the target object enters the parking lots from the above-ground level 1, the underground level 1 is reached first, because the structural composition of the target areas is different, after the target object enters the target areas, the target floor where the target object is located needs to be determined first; and then acquiring a navigation sub-path passing through the target floor from the navigation path data, and finally rendering the navigation sub-path in a map layer corresponding to the target floor to provide navigation path data aiming at different floors for the target object.

and fusing the navigation path sub-data according to the floor identification carried by the navigation path sub-data to obtain navigation sub-paths corresponding to different floors.

In the navigation path data, there may be a plurality of navigation path sub-data having the same floor identifier, that is, corresponding to the same floor of the target area, and the plurality of navigation path sub-data having the same floor identifier are different from each other but have a certain path sequence therebetween. Therefore, in this embodiment, the navigation path sub-data may be subjected to fusion processing according to the floor identifier carried by the navigation path sub-data, so as to obtain a complete navigation sub-path corresponding to different floors of the target area.
In an embodiment of the present disclosure, the step of fusing the navigation path sub-data according to the floor identifier carried by the navigation path sub-data to obtain the navigation sub-paths corresponding to different floors may include the following steps:
acquiring navigation path sub-data with the same floor identification from the navigation path data;
and connecting the navigation path sub-data with the same floor identification according to the path sequence of the navigation path sub-data to generate navigation sub-paths corresponding to different floors.
As mentioned above, the navigation path data may include one or more navigation path sub-data carrying different floor identifiers, where the navigation path sub-data having the same floor identifier, that is, the navigation path sub-data corresponding to the same floor of the target area may have a plurality of sub-data, and the plurality of navigation path sub-data having the same floor identifier are different from each other, but have a certain path sequence therebetween. Therefore, when the navigation path subdata is fused, the navigation path subdata with the same floor identification needs to be obtained first, and the navigation path subdata is data which can form the navigation path data of the same floor corresponding to the target area; and then according to the path sequence of the navigation path subdata, sequentially connecting the navigation path subdata with the same floor identification to obtain navigation subpaths corresponding to different floors of the target area.

and rendering the navigation sub-path in the map layer corresponding to the target floor by using a preset color and a preset rendering mode.
In order to enable the traffic information of the navigation sub-paths to be transmitted simultaneously or to distinguish the navigation sub-paths of different floors when rendering the navigation sub-paths, in this embodiment, the navigation sub-paths are rendered in the map layer corresponding to the target floor by using a preset color and a preset rendering mode according to the requirements of practical application. For example, the navigation sub-path may be rendered by using colors representing different road conditions and bars having a width of a predetermined pixel, for example, a deep red color system representing a heavily congested road condition, a red color system representing a congested road condition, a yellow color system representing a slow traffic road condition, a green color system representing a normal smooth road condition, and a deep green color system representing an extremely fast smooth road condition may be used to render the navigation sub-path, so as to indicate the road condition in the corresponding floor of the target area while guiding the traveling direction of the target object. For another example, the navigation sub-paths can be rendered by using colors representing different floors, so that the navigation sub-paths of different floors can be distinguished, the path navigation effect is improved, and the user experience is improved.
The following are embodiments of the disclosed apparatus that may be used to perform embodiments of the disclosed methods.
