In the process of tourists playing in scenic spots, the tourists may get lost due to the large area of the scenic spots, poor sense of direction of the tourists, and the like. Currently, attractions typically direct a route for a guest by setting a attraction map at a particular location. However, places where scenic spot maps are set are limited, and it is difficult to quickly obtain navigation guidance information when tourists get lost in places other than those places.
Based on the above, the embodiment of the application provides a navigation guidance method, so as to provide navigation guidance information in time when a tourist gets lost.
Referring to fig. 1, fig. 1 is an application environment diagram of a navigation guidance method according to an embodiment of the present application. The application environment relates to a terminal device 101 and a cloud server 102, and the terminal device 101 is in communication connection with the cloud server 102. The terminal device 101 is provided with a positioning module, which is configured to obtain positioning information of the tourist, and when determining that the tourist gets lost, the terminal device 101 sends lost early warning information to the cloud server 102, where the lost early warning information includes a current position of the tourist. The cloud server 102 receives and responds to the lost early warning information, and returns navigation guidance information to the terminal equipment 101. The terminal device 101 receives and plays navigation guidance information including a navigation route for guiding the guest to a target location from a current location. Wherein the terminal device 101 may be, but is not limited to, various portable devices such as smart phones, charger. Cloud server 102 may be implemented as a stand-alone server or as a cluster of servers.
The execution subject of the navigation guidance method may be a navigation guidance apparatus, and for example, the navigation guidance method may be executed by the terminal device 101 in fig. 1. In some possible implementations, the navigation directions method may be implemented by way of a processor invoking computer readable instructions stored in a memory.
Referring to fig. 2, fig. 2 is a flowchart of a navigation guidance method provided in an embodiment of the present application, and the application of the navigation guidance method to a terminal device is illustrated by way of example, and includes the following steps S201 to S203.
S201, positioning information of tourists is acquired.
The tourist carries the terminal equipment when playing in the scenic spot, is provided with positioning module in the terminal equipment, obtains the location information of tourist through positioning module, can obtain the current position of tourist according to the location information of tourist.
In one possible implementation, the terminal device may implement real-time positioning of the guest through a Beidou positioning system or a global positioning system (Global Positioning System, GPS).
In another possible implementation manner, an electronic tour guide map is arranged in the terminal device, and during the playing process of the tourist, the electronic tour guide map automatically records the historical access position of the tourist, and the current position of the tourist can be estimated according to the historical access position of the tourist without a positioning signal.
Each scenic spot in the electronic tour guide map is provided with an indicator lamp, when a tourist passes a scenic spot, the indicator lamp corresponding to the scenic spot is lightened, the lightened indicator lamps are connected along a scenic spot road, a historical play path of the tourist can be obtained, and then the current position of the tourist can be estimated according to the travelling direction of the historical play path. For example, assuming that the attraction recently passed by the tourist in the history playing path is attraction a, the traveling direction is the south-facing direction, if the attraction closest to attraction a is attraction B while continuing to walk in the south-facing direction, it may be estimated that the current position of the tourist is between attraction a and attraction B.
S202, when determining that the tourist gets lost, sending lost early warning information to the cloud server, wherein the lost early warning information comprises the current position of the tourist.
In the process of tourist playing, the terminal equipment judges whether the tourist gets lost, and when the tourist gets lost, the terminal equipment sends lost early warning information to the cloud server, wherein the lost early warning information is used for requesting the cloud server to send navigation guidance information. The lost early warning information can carry current positioning information of the tourist, and the current positioning information of the tourist is used for representing the current position of the tourist.
And S203, receiving and playing navigation guide information sent by the cloud server in response to the lost-route early warning information, wherein the navigation guide information comprises a navigation route for guiding the tourist to go to the target position from the current position.
After receiving the lost early warning information, the cloud server acquires the current position of the tourist from the lost early warning information and acquires the target position. Optionally, the cloud server takes the current position of the tourist as a starting point and takes the target position as an end point, plans a navigation route from the current position of the tourist to the target position, and then obtains navigation guidance information. In addition, a background person can access the cloud server through a computer, a mobile phone and other equipment to obtain lost early warning information, plan a navigation route from the current position of the tourist to the target position, and send navigation guide information containing the navigation route to the cloud server in a text or voice mode, namely the cloud server can obtain the navigation guide information from the equipment end of the background person.
The target position is a place position for prompting the lost tourist to go to. In an example, the target location may be a preset location, such as a location within a scenic spot where a map of the scenic spot is located, a thoroughfare location, a canteen location, a restroom location, or other location that is not prone to getting lost or people, which may be pre-stored in the cloud server for direct retrieval by the cloud server.
In other examples, the target location may also be a location that is actively provided by the guest. Specifically, a voice receiving module is further arranged in the terminal equipment, voice information containing the target position and sent by the tourist is obtained through the voice receiving module, the target position and the lost early warning information are sent to a cloud server, and the cloud server obtains the target position from the received information.
After the cloud server obtains the navigation guide information, the navigation guide information is sent to the terminal equipment, and the navigation guide information comprises a navigation route for guiding the tourist to go to the target position from the current position. The terminal equipment is also provided with a voice playing module, and after receiving the navigation guide information, the terminal equipment plays the navigation guide information through the voice playing module so as to guide the tourist to go to the target position from the current position.
In the above embodiment, when determining that the tourist gets lost, the terminal device sends the lost early warning information to the cloud server, and receives and plays the navigation guidance information sent by the cloud server in response to the lost early warning information, so that remote scenic spot navigation can be realized, and the navigation guidance information can be provided for the lost tourist in time.
It should be noted that, the information transmission referred to herein may be implemented by Long Range Radio (LoRA) or narrowband internet of things (Narrow Band Internet of Things, NB-IoT) technology. Among these, the transmission distances to which LoRA is applicable may be, but are not limited to, distances on the order of ten meters, hundred meters, and kilometers. For example, the terminal device uploads the lost early warning information to the cloud server through LoRA or NB-Iot, and the cloud server issues the navigation guidance information to the terminal device through LoRA or NB-Iot.
Optionally, the information transmission is realized by a kilometer voice transmission technology, and the core content of the kilometer voice transmission technology is compression coding and channel coding based on LoRA protocol transmission. Taking navigation guidance information transmission between a cloud server and terminal equipment as an example, the cloud server firstly carries out digital conversion on the navigation guidance information to obtain a first digital signal; the cloud server encodes the first digital signal to obtain a second digital signal, and the encoding process comprises compression encoding and channel encoding, so that the stability and reliability of transmission are improved; then the cloud server sends the second digital signal to the terminal equipment; after receiving the second digital signal, the terminal device performs decoding and analog signal conversion on the second digital signal to obtain corresponding information, and plays the information through the voice playing module.
The information can be audio information, text information or instructions. It should be noted that when the information is audio information, the voice playing module can directly play the audio information when receiving the information; when the information is text information, the voice playing module firstly converts the text information into corresponding audio information through a voice-to-text technology, and then plays the audio information; when the information is an instruction, the voice playing module firstly analyzes the instruction to obtain a voice template corresponding to the instruction (a plurality of voice templates can be recorded in the voice playing module in advance), and then plays the voice template.
In one possible implementation manner, before the step of sending the lost-route early warning information to the cloud server when determining that the tourist gets lost, the method may further include the following steps: and determining whether the tourist gets lost according to the positioning information.
The positioning information of the tourist can reflect the real-time position and the real-time position change condition of the tourist, and the real-time position change condition of the tourist can be used for judging whether the tourist gets lost or not. After the terminal equipment obtains the positioning information of the tourist, whether the tourist gets lost or not is determined according to the positioning information. For example, if the location of the guest is in an area that is prone to getting lost for a long time, the terminal device may determine that the guest gets lost.
In the above embodiment, the terminal device determines whether the tourist gets lost according to the positioning information of the tourist, thereby providing a way for automatically judging whether the tourist gets lost, and can make the judgment of getting lost of the tourist in time and provide navigation guidance information for the tourist in time under the condition that the tourist does not realize that the tourist gets lost.
In one possible implementation manner, determining whether the tourist gets lost according to the positioning information may specifically include: if the time length that the position of the positioning information is continuously in the preset area reaches the first preset time length or the time length that the people flow in the area where the positioning information is continuously smaller than the preset people flow reaches the second preset time length, determining that the tourist gets lost.
The location of the positioning information may be understood as the location indicated by the positioning information, and may also be understood as the real-time location of the guest. The preset area may be understood as an area which is easy to get lost in a preset scenic spot, for example, an unopened area, an area with more branches, an area with less people traffic counted according to historical data, and the like. The area where the positioning information is located can be understood as an area surrounded by a preset distance as a radius with the position where the positioning information is located as a center.
Along with the walking of the tourist, the position of the positioning information can change in real time, and if the position of the positioning information is in a preset area for a long time, the tourist can be considered to get lost. Based on the first preset time length is introduced and used for representing the minimum time length required to be met for determining the time length that the position of the positioning information is continuously in the preset area when the tourist gets lost. If the duration that the position of the positioning information is continuously in the preset area reaches the first preset duration, the terminal equipment determines that the tourist gets lost.
Along with the walking of the tourist, the area where the positioning information is located can change in real time, the terminal equipment obtains the people flow of the area where the positioning information is located, and if the people flow of the area where the positioning information is located is smaller than the preset people flow for a long time, the tourist can be considered to get lost. Based on the above, a second preset duration is introduced to characterize the minimum duration required to be satisfied when the traffic of the area where the positioning information is located is continuously smaller than the duration of the preset traffic when the tourist gets lost. If the time length that the people flow in the area where the positioning information is located is continuously smaller than the preset people flow reaches the second preset time length, the terminal equipment determines that the tourist gets lost.
It should be noted that, the specific values of the first preset duration, the second preset duration, the preset distance, and the preset traffic flow may be set in combination with actual situations, which is not limited herein. The first preset duration and the second preset duration may be the same or different.
In the above embodiment, the terminal device may determine whether the tourist gets lost more accurately by determining whether the duration of the location information in the preset area reaches the first preset duration, or whether the duration of the location information in the area where the traffic is smaller than the preset traffic reaches the second preset duration.
In one possible implementation manner, determining whether the tourist gets lost according to the positioning information may specifically include: if the time length that the position of the positioning information is continuously in the preset area reaches a first preset time length or the time length that the people flow in the area where the positioning information is continuously smaller than the preset people flow reaches a second preset time length, playing a first inquiry voice, wherein the first inquiry voice is used for inquiring whether a tourist gets lost or not; if a first reply voice responding to the first inquiry voice is monitored within a first preset time after the first inquiry voice is played, and the first reply voice represents the lost, determining that the tourist gets lost.
If the duration that the position of the positioning information is continuously in the preset area reaches the first preset duration, or if the duration that the people flow in the area where the positioning information is continuously smaller than the preset people flow reaches the second preset duration, the terminal equipment preliminarily judges that the tourist gets lost, and in order to further improve the judgment accuracy, the terminal equipment plays a first inquiry voice on the basis, and is used for confirming whether the tourist gets lost or not. For example, the content of the first query voice may be "please ask you if you get lost.
After hearing the first inquiry voice sent by the terminal device, the tourist can perform corresponding voice reply. After the terminal equipment finishes playing the first inquiry voice, monitoring whether reply voice responding to the first inquiry voice exists or not in a certain time, and further judging whether the tourist is truly lost or not according to the monitoring result. Based on this, a first preset time is introduced to characterize the longest time for continuously monitoring whether there is a reply voice responding to the first query voice, and a specific value of the first preset time may be set in combination with the actual situation, which is not limited herein.
If the terminal device monitors the first reply voice responding to the first query voice within a first preset time after the first query voice is played, and the first reply voice represents the lost, the terminal device determines that the tourist gets lost. For example, the content of the first reply voice characterizing the labyrinth may be "yes".
If the terminal equipment monitors the first reply voice responding to the first inquiry voice within a first preset time after the first inquiry voice is played, and the first reply voice represents that no lost exists, the terminal equipment confirms that no lost exists, and therefore the terminal equipment determines that no lost exists. For example, the content characterizing the first reply voice without the labyrinth may be "not".
If the terminal device does not monitor the reply voice responding to the first query voice within a first preset time after the first query voice is played, this may be because the tourist does not notice the first query voice. Based on the above, the terminal device may replay the first query speech, and monitor whether there is a reply speech responding to the first query speech within a first preset time after the first query speech is replayed. In one example, if the terminal device does not hear the reply voice in response to the first query voice N consecutive times, it is determined that the guest is not lost. The value of N may be set in combination with actual requirements, and is not limited herein, for example, n=2.
In the above embodiment, when the duration that the location information is in the preset area continuously reaches the first preset duration, or the duration that the traffic of people in the area where the location information is in the preset area continuously is smaller than the preset traffic reaches the second preset duration, the terminal device further inquires whether the tourist gets lost, and then judges whether the tourist gets lost according to the feedback information of the tourist, thereby being beneficial to improving the judgment accuracy.
In one possible implementation manner, before the step of sending the lost-route early warning information to the cloud server when determining that the tourist gets lost, the method may further include the following steps: and monitoring voice information of the tourist, and determining whether the tourist gets lost according to the monitored voice information.
The terminal equipment can actively monitor the voice information of the tourist and determine whether the tourist gets lost or not according to the monitored voice information. For example, if the terminal device listens to the voice information characterizing the lost, the terminal device may determine that the guest is lost.
In the above embodiment, the terminal device determines whether the tourist gets lost according to the monitored voice information, thereby providing an active help seeking approach for the lost tourist, and the tourist can inform the terminal device through voice when aware of the lost tourist, so that the terminal device can timely make the judgment of the lost tourist and timely provide navigation guidance information for the tourist.
In one possible implementation, determining whether the guest gets lost according to the monitored voice information may specifically include: if the wake-up voice is monitored, playing a second inquiry voice, wherein the second inquiry voice is used for inquiring whether the tourist gets lost or not; if a second reply voice responding to the second inquiry voice is monitored within a second preset time after the second inquiry voice is played, and the second reply voice represents the lost, determining that the tourist gets lost.
Wake-up speech refers to speech that wakes up a terminal device to open a dialog. Illustratively, the content of the wake-up speech may be "small tour xiao You". After the terminal equipment monitors the wake-up voice, a second inquiry voice is played for inquiring whether the tourist gets lost or not. For example, the content of the second query voice may be "please ask you if you get lost".
After hearing the second inquiry voice sent by the terminal device, the tourist can perform corresponding voice reply. After the terminal equipment finishes playing the second inquiry voice, monitoring whether reply voice responding to the second inquiry voice exists or not in a certain time, and judging whether the tourist gets lost or not according to the monitoring result. Based on this, a second preset time is introduced to characterize the longest time for continuously monitoring whether there is a reply voice responding to the second query voice, and a specific value of the second preset time may be set in combination with the actual situation, which is not limited herein.
If the terminal device monitors the second reply voice responding to the second query voice within a second preset time after the second query voice is played, and the second reply voice represents the lost, the terminal device determines that the tourist gets lost. Illustratively, the content of the second reply voice that characterizes the labyrinth may be "yes".
If the terminal equipment monitors the second reply voice responding to the second inquiry voice within a second preset time after the second inquiry voice is played, and the second reply voice represents no lost, the terminal equipment confirms that the tourist does not get lost, and therefore the terminal equipment determines that the tourist does not get lost. For example, the content characterizing the second reply voice without the labyrinth may be "not".
If the terminal device does not monitor the reply voice responding to the second query voice within a second preset time after the second query voice is played, this may be because the tourist does not notice the second query voice. Based on the above, the terminal device may replay the second query speech, and monitor whether there is a reply speech responding to the second query speech within a second preset time after the second query speech is replayed. In one example, if the terminal device does not hear the reply voice in response to the second query voice M consecutive times, it is determined that the guest is not lost. The value of M may be set in connection with actual requirements, and is not limited herein, for example, m=2.
In the above embodiment, the terminal device inquires whether the tourist gets lost after hearing the wake-up voice, and then judges whether the tourist gets lost according to the feedback information of the tourist, thereby being beneficial to improving the judgment accuracy.
In one possible implementation, after determining that the guest gets lost, the method may further include the steps of: playing a third inquiry voice for inquiring a target place to which the tourist wants to go; if a third reply voice responding to the third query voice is monitored within a third preset time after the third query voice is played, and the third reply voice contains target location information, adding the target location information into the lost early warning information, wherein the target location information is used for determining a target position.
After determining that the tourist gets lost, the terminal device plays a third inquiry voice for inquiring the target place to which the tourist wants to go. For example, the content of the third query voice may be "please ask you which one wants to go to".
After hearing the third inquiry voice sent by the terminal device, the tourist can perform corresponding voice reply. After the third inquiry voice is played, the terminal equipment monitors whether reply voice responding to the third inquiry voice exists or not in a certain time, and determines a target place to which the tourist wants to go according to the monitoring result. Based on this, a third preset time is introduced to characterize the longest time for continuously monitoring whether there is a reply voice responding to the third query voice, and a specific value of the third preset time may be set in combination with the actual situation, which is not limited herein.
If the terminal device monitors a third reply voice responding to the third query voice within a third preset time after the third query voice is played, and the third reply voice contains target location information, the terminal device means that the tourist has a determined target location to which the tourist wants to go, and therefore the terminal device adds the target location information to the lost early warning information and sends the lost early warning information to the cloud server together, and the cloud server determines a target position based on the target location information. For example, the content of the third reply voice including the target location information may be "i want to go to the scenic spot east gate", where "scenic spot east gate" is the target location, and the corresponding target location is where the scenic spot east gate is located.
If the terminal device monitors a third reply voice responding to the third query voice within a third preset time after the third query voice is played, and the third reply voice does not contain target location information, the terminal device means that the tourist does not have a determined target location to which the tourist wants to go, and therefore the terminal device does not need to send the target location information to the cloud server, and the cloud server determines the target location based on the preset location.
If the terminal device does not monitor the reply voice responding to the third query voice within a third preset time after the third query voice is played, this may be because the tourist does not notice the third query voice. Based on the above, the terminal device may replay the third query speech, and monitor whether there is a reply speech responding to the third query speech within a third preset time after the third query speech is replayed. In an example, if the terminal device does not monitor the reply voice in response to the third query voice for K consecutive times, it is considered that the tourist does not have a determined target location to which he wants to go, so the terminal device does not need to send the target location information to the cloud server, and the cloud server determines the target location based on the preset location. The value of K may be set in combination with actual requirements, and is not limited herein, for example, k=2.
In the above embodiment, the terminal device determines the target location to which the tourist wants to go according to the monitored voice information, thereby providing a way for actively informing the target location for the lost tourist, and then providing the navigation route from the current position to the position where the target location is located for the tourist, so as to better satisfy the actual requirement of the tourist.
