Description
Technical Field
The embodiments of the present invention relate to, but not limited to, the field of positioning and navigation, and in particular, but not limited to, a positioning and navigation method, apparatus, terminal, server, system, and storage medium.
Background
With the development of society and the improvement of infrastructure, the layout of streets and buildings in cities is more and more complex, and people are more and more inclined to use terminals such as mobile phones for navigation when going out to a certain destination. However, positioning and navigation based on GPS (Global positioning System, the same below) or cellular data often only meet the requirements in outdoor environments. Because GPS and cellular data signals are affected by buildings, the GPS and cellular data signals cannot provide services well indoors or under the condition that a plurality of buildings are covered, and in reality, a plurality of activities of people occur indoors, and meanwhile, in a plurality of scenes, people also need to perform positioning and navigation in the indoor environment. For example, in a large shopping mall, due to the complex internal structure, a user sometimes needs to find a specific shop for a long time, or in a hospital, a user needs to find some departments and needs to perform positioning and navigation indoors.
In the related art, indoor positioning mainly includes an indoor positioning and routing panorama guiding method based on a two-dimensional code, and an indoor positioning method based on a distance.
An indoor positioning and routing panorama guiding method based on two-dimensional codes belongs to the technical field of web (web pages). When the system is used, a specific two-dimensional code needs to be scanned to obtain the current position information of a user, then the user inputs a destination address at a mobile phone end, after the information is submitted, a request is sent to a server through an AJAX (asynchronous JavaScript and XML) technology in a non-refreshing interface mode, the server calls a database to obtain data required by a corresponding routing algorithm, a path array is output through proper routing algorithm operation, a navigation interface prompts the path to generate completed information, and after the user is switched to a next scene, a next button xt on a screen needs to be manually clicked to switch and relocate until a destination is reached. According to the technology, the two-dimensional codes containing the position information of the points are arranged at certain specific positions, so that a user can only find the specific points as positioning starting points and cannot perform positioning navigation by taking any indoor position as the starting point.
The indoor positioning method based on the distance is characterized in that the horizontal distance from the indoor positioning equipment to each wall is determined according to the vertical distance from the indoor positioning equipment to the ceiling and the vertical deflection angle corresponding to the shortest distance from the indoor positioning equipment to the wall corner line between the ceiling and each wall, and the indoor positioning is realized. The method cannot perform good positioning when the indoor environment layout is the same.
Aiming at the problems in the related art, no convenient, accurate and high-applicability indoor positioning navigation method exists at present.

The wireless network that can be used to the location is the wireless network that has data transmission ability, including but not limited to wireless networks such as WIFI, bluetooth, and preferably, can adopt WIFI as the wireless network that is used for the location.
And after the terminal is connected with the wireless network, acquiring configuration information in the wireless network information and channel state information of the wireless network connected with the terminal. Taking WIFI connection as an example, an SSID (Service Set identifier, the same below) and channel state information of WIFI connected to the terminal are obtained. After the configuration information and the channel state information of the wireless network are acquired, the configuration information and the channel state information are sent to the sub-server, the sub-server can determine the area where the terminal is located through the configuration information of the wireless network, and the current position information of the terminal in the area is obtained by matching the channel state information with data in a fingerprint database. And sending the obtained destination address information to the sub-server, wherein the obtaining of the destination address comprises but is not limited to receiving the input content of the input box, receiving a target point marked on the map and the like. In some embodiments, the terminal may also send the destination address information directly to the overall server. The sub-server is a sub-server corresponding to the area where the terminal is located.
Step S102: and receiving and displaying navigation information which is sent by the sub-server and corresponds to the destination address information.
In this step, the terminal receives the navigation information transmitted by the sub server and displays it on the map. The specific content of the navigation information corresponds to the destination address information, including but not limited to the proper path from the terminal to the destination address, the prompt information of each special position or intersection, and so on.

The channel state information of a wireless signal describes the fading factor of the signal on each transmission path, which is represented as a value of each element in the channel gain matrix, which describes the complex values of the amplitude h (f) and phase variation between the transmitter and receiver at subcarrier f. In an indoor environment, due to the influence of multipath effect, in the transmission process of a wireless signal from a transmitter to a receiver, different subcarriers experience selective fading of power, but not all subcarriers are equally influenced by multipath, so after channel state information of a wireless network connected with a terminal is obtained, the channel state information needs to be screened, subcarriers with small influence of multipath effect in all subcarriers are screened, and a channel state information measured value of the terminal to be measured is obtained.

s301: and receiving the current position information and the destination address information of the terminal sent by the sub-server.
In this step, the overall server receives the terminal current location information and the destination address information transmitted from the sub-server. And the current position information of the terminal is obtained by the sub-server through determining the area of the terminal through the wireless network information, screening the channel state information and then matching the channel state information with the data in the database.
S302: and planning a path from the current position of the terminal to the destination address according to the current position information and the destination address information of the terminal.
In the step, the main server matches the current position of the user with the target position in a local map according to the current position information and the destination address information of the terminal, and a proper path is planned. Suitable paths include, but are not limited to, the shortest distance path, the shortest time path, and the like.
S303: and sending navigation information to the sub server according to the planned path.
In this step, the overall server sends navigation information to the sub-servers after planning a suitable path.
