Detailed Description

In order to enable those skilled in the art to better understand the embodiments of the present application, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, shall fall within the scope of the present application.

The terms "first" and "second" are used below for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the embodiments of the present application, unless otherwise indicated, the meaning of "a plurality" is two or more.

Currently, existing map navigation software only supports a single map navigation mode, such as only an outdoor navigation mode or only an indoor navigation mode. However, when the destination of the travel route of the user is a store inside the mall, the user can only navigate to the surroundings of the mall by using the map navigation software supporting the outdoor navigation mode, and the navigation is automatically stopped. If the user navigates to the gate of the mall, the user automatically stops navigating. If the user cannot find a specific store, the user is required to start the map navigation software supporting the indoor navigation mode again, so that the user operation is complicated, and the user traveling experience is reduced.

Especially when the user drives and navigates, the user firstly uses the vehicle-mounted navigator to navigate the driving route, and when the end point of the driving route is reached, the vehicle-mounted navigator stops navigating. On the basis, if the user needs to further navigate to a specific store in the store, the map navigation software supporting the indoor navigation mode on the mobile phone needs to be started, and the user needs to navigate to the specific store in the store from the current position of the user.

Illustratively, as shown in fig. 1, after the mobile phone responds to the destination input by the user on the map navigation software and selects the driving navigation, the mobile phone displays a route planning interface as shown in (1) in fig. 1, wherein the route planning interface comprises a driving navigation route from the departure place to the destination determined by the map navigation software according to the destination input by the user. For example, when the destination input by the user is a store inside the mall, referring to (1) in fig. 1, the map navigation software determines that the end point of the driving route is the periphery of the mall (e.g., a mall parking lot, a mall gate, etc.). As shown in fig. 1 (1), the mobile phone responds to the operation of starting navigation by the user, the mobile phone displays a navigation interface shown in fig. 1 (2), and the user can drive according to the navigation route; when the user drives to the end of the driving route, the navigation is automatically stopped.

As can be seen from fig. 1, in the existing map navigation software, no matter the route planning or the actual navigation interface, the map navigation software can not specifically reach the shops in the mall, and the navigation needs of the users cannot be satisfied, thereby reducing the appearance experience of the users.

The embodiment of the application provides a navigation method, which is used for navigation of a first travel route supported by the navigation method; wherein the destination of the first travel route is located inside the target building; the method can directly navigate to the destination in the target building, meets the diversified navigation requirements of users, and improves the travel experience of the users. Specifically, the first travel route comprises an outdoor navigation route and an indoor navigation route, in the navigation process of the first travel route, the mobile terminal starts navigation based on the outdoor navigation route, and when the mobile terminal reaches the periphery of a target building, the mobile terminal automatically switches from the outdoor navigation route to the indoor navigation route to continue navigation; or the vehicle-mounted equipment starts navigation based on the outdoor navigation route, and when the vehicle-mounted equipment reaches the periphery of the target building, the vehicle-mounted equipment sends a navigation switching command to the mobile terminal; and then the mobile terminal responds to the navigation switching command and continues navigation based on the indoor navigation route.

For example, taking a shop with a destination of the first travel route as a building 3 (3F) of a certain mall as an example, as shown in fig. 2, in the navigation process of the first travel route, navigation is started from a departure place based on an outdoor navigation route, and when the navigation reaches the periphery of the mall (such as a destination of the outdoor navigation route, a mall parking lot, a mall entrance and the like), the navigation is automatically switched to an indoor navigation route to continue the navigation until the navigation task is finished after the destination is reached.

The target building may be, for example, a mall, a large office building, an indoor scenic spot, etc., which is not limited in the embodiment of the present application. In the case where the target building is a mall, the destination of the first travel route may be, for example, a store inside the mall, such as a clothing store, a restaurant, or the like.

The navigation method provided in the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

The navigation method provided by the embodiment of the application can be applied to a navigation system, wherein the navigation system is used for navigating a first travel route, and the destination of the first travel route is located in a target building.

In some embodiments, as shown in fig. 3, a navigation system 10 is provided in an embodiment of the present application, where the navigation system 10 includes: mobile terminal 100 and server 200. The server 200 may provide the navigation information of the first travel route to the mobile terminal 100, and the mobile terminal 100 may navigate the first travel route based on the navigation information of the first travel route provided by the server 200.

In the present embodiment, the server 200 stores indoor navigation data models of a plurality of buildings. For example, a tester may collect 3D data of the indoor of each building, and then model the 3D data of the indoor of each building to obtain an indoor navigation data model of each building; and stores the indoor navigation data model of each building in a server 200 (e.g., cloud server). The server 200 may open an access interface to the mobile terminal 100, so that the mobile terminal 100 may acquire the indoor navigation data model of the target building through the access interface.

Illustratively, the 3D data in the room of each building includes at least position profile coordinates and height information of a plurality of objects in the building room. Wherein, the plurality of objects in the building room refer to each activity place in the building room. For example, when the building is a mall, the pair of objects in the building refer to each of the malls in the building. In the embodiment of the present application, if the destination is located in a building room, the destination is an object in the building room, that is, the destination is an activity place in the building room.

In the navigation process of the first travel route, the mobile terminal 100 first performs navigation based on the outdoor navigation route, and if the mobile terminal 100 meets the first preset condition, the mobile terminal 100 sends the identification of the target building to the server 200. After the server 200 receives the identifier of the target building sent by the mobile terminal, the server 200 selects an indoor navigation data model corresponding to the identifier of the target building from the indoor navigation data models of the plurality of buildings, that is, the server 200 selects the indoor navigation data model of the target building from the indoor navigation data models of the plurality of buildings. After that, the server 200 transmits the indoor navigation data model of the target building to the mobile terminal 100. After the mobile terminal 100 receives the indoor navigation data model of the target building, the mobile terminal 100 matches the indoor navigation data model of the target building based on the current position (or position information) of the mobile terminal 100, and generates navigation information from the current position of the mobile terminal 100 to the destination in the target building. Subsequently, the mobile terminal 100 performs navigation based on the navigation information of the current location to the destination.

Also, as an example, in the navigation process of the first travel route, the mobile terminal 100 first performs navigation based on the outdoor navigation route, and if the mobile terminal 100 meets the first preset condition, the mobile terminal 100 sends a navigation acquisition request to the server 200, where the navigation acquisition request includes the identification of the target building and the location information of the mobile terminal 100. When the server 200 receives the navigation acquisition request transmitted from the mobile terminal 100, the server 200 first selects an indoor navigation data model corresponding to the identification of the target building from among the indoor navigation data models of the plurality of buildings based on the identification of the target building, that is, the server 200 selects an indoor navigation data model of the target building from among the indoor navigation data models of the plurality of buildings. On this basis, the server 200 matches the location information of the mobile terminal 100 with an indoor navigation data model of the target building, and generates navigation information from the current location of the mobile terminal to the destination within the target building. Subsequently, the server 200 transmits the generated navigation information from the current location of the mobile terminal to the destination in the target building to the mobile terminal 100, and the mobile terminal 100 performs navigation based on the navigation information from the current location to the destination.

The first preset condition comprises: the distance between the mobile terminal 100 and the target location is less than a preset distance threshold. The target location may be, for example, an end point of an outdoor navigation route, a target building or a preset location (such as a parking lot entrance, a target building doorway), and the like.

By way of example, the mobile terminal 100 in the navigation system 10 described above may be a mobile terminal having a navigation function. For example, the mobile terminal may be a mobile phone, a watch, a bracelet, a smart glasses, a tablet, a desktop, a laptop, a handheld computer, a super mobile personal computer (ultra-mobile personal computer, UMPC), a netbook, a personal digital assistant (personal digital assistant, PDA), an augmented reality (augmented reality, AR) \virtual reality (VR) device, etc., and the embodiments of the present application do not limit the specific form of the mobile terminal.

In addition, the server 200 in the navigation system 10 may be a server of a navigation Application (APP) on the mobile terminal 100; the navigation APP may be a third party navigation APP or a navigation APP carried by the system of the mobile terminal 100, which is not limited in this embodiment of the present application.
