All other embodiments, which are obtained by a person skilled in the art based on the embodiments of the present application, fall within the scope of protection of the present application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type, and are not limited to the number of objects, such as the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
As urban buildings are expanded, indoor spaces become larger and more complex, such as the interiors of large buildings, e.g., shopping centers, convention centers, libraries, warehouses, underground parking lots, etc. To facilitate user activity, idle locations are often provided in some large indoor spaces for placement of personal items of the user. The user extracts personal items based on the route to the storage location when the items need to be extracted by remembering the route back to the location where the personal items are stored.
However, because the indoor space is large and more complex, and because the indoor space generally has the condition that satellite positioning signals are weak, the problem that navigation route is provided for the user based on the satellite positioning signals and positioning information cannot be provided accurately often exists, the user needs to remember the route returned to the storage position as far as possible, and even if the user remembers the route, if the user is unfamiliar with the environment of the indoor space, the process of searching the storage position is still difficult, so that the memory burden of the user is large and the user is influenced to find personal articles quickly.
Aiming at one or more problems existing in the prior art, the embodiment of the application provides a navigation information generation method, a device, electronic equipment and a readable storage medium, which can provide navigation information to guide a user to quickly find a first position and reduce the memory burden of the user.
The method, the device, the electronic equipment and the readable storage medium for generating the navigation information provided by the embodiment of the application are described in detail through specific embodiments and application scenes thereof with reference to the accompanying drawings.
Fig. 1 is a flowchart of a method for generating first navigation information according to an embodiment of the present application, and is shown in fig. 1. The first navigation information generating method may include steps 110 to 140.
Step 110, obtaining first status information of the user from the first location to the second location, wherein at least one acquisition point is included between the first location and the second location, and the first status information corresponding to each acquisition point includes first wireless signal information and first direction information.
Step 120, obtaining second state information in case that the user returns to the first position, wherein the second state information includes second wireless signal information.
Step 130, determining the similarity between the second state information and the first state information of each acquisition point.
In step 140, the acquisition point with the greatest similarity is determined as the first target position.
Step 150, determining and displaying the first target moving direction according to the first target position and the first state information corresponding to the first target position.
The above steps are described in detail below, and are specifically described below.
Specifically, referring to step 110, the first location may be a location where the user passes through in the venue, and after a period of time, the user needs to return to the first location. The second location may be one where the user leaves the venue. The places are, for example, parking lots, shopping centers, exhibition centers, libraries, warehouses, gyms and other buildings with large space.
The first wireless signal information may include a device identification of the wireless device in the venue and may also include a signal strength of the wireless device in the venue. The first direction information may represent a direction of movement of the user at each acquisition point.
For example, a plurality of wireless devices may be installed in a venue for providing communication signals for a user. The wireless signals emitted by each wireless device can cover a certain range, and the mobile terminal can detect the wireless signals emitted by the wireless devices, so that the related information of the wireless devices in the environment where the mobile terminal is located is obtained. For example, the information about the wireless device may include information such as a device identification of the wireless device and a signal strength of a wireless signal of the wireless device. Illustratively, the mobile terminal may collect a basic service set (Basic Service Set ID, BSS ID) of the wireless device, thereby obtaining a device identification of the wireless device.
The first direction information may represent a direction of movement of the user at each acquisition point. Optionally, the mobile terminal may include an acceleration sensor, a magnetic field sensor, a gyroscope, and other sensors, and in the process of moving by the user, the mobile terminal may determine the moving direction of the user according to the sensors. For example, the three-axis acceleration sensor can determine the pose of the mobile terminal relative to the earth's surface, and the magnetic field sensor and the gyroscope can determine the orientation of the mobile terminal based on the southwest and northwest directions.
The user can carry the mobile terminal with him to enter the place, wherein the mobile terminal is an electronic device such as a smart phone, a tablet computer, a smart bracelet, a smart watch, and a notebook computer. Whether the user returns to the location can be detected by the mobile terminal. For example, the mobile terminal determines that the mobile terminal enters the venue by detecting a wireless signal sent by a wireless device within the venue; for another example, the user turns on the search function of the mobile terminal to determine that the user is back at the venue and needs to search for the first location within the venue.
In the embodiment of the application, after the user enters the place, the target object can be placed at the first position in the place so as to facilitate the user to move in the place or outside the place. The target object is, for example, a personal object that a user needs to place in a place, such as a vehicle, a package, a document, etc. By returning to the first location, the user may re-find the target object, which may be, for example, the user returning to a parking lot for a vehicle, or, for example, the user returning to a store for items within the mall for a store. The first location may also be a specific location in a venue, for example a specific seat in a gym, which is returned to after a period of time when the user leaves the first location where the seat is located.
The mobile terminal may detect whether the user leaves the first location and whether the user leaves the location where the first location is located. And acquiring wireless signals and the moving direction of the mobile terminal in real time in a time period from the mobile terminal leaving the first position to the place where the mobile terminal leaves the first position, so as to obtain at least one acquisition point, and the first state information corresponding to each acquisition point comprises first wireless signal information and first direction information.
In one example, taking a target object as a vehicle as an example, a position of a user in a parking lot where the vehicle is always parked is a first position, a manner that the mobile terminal detects whether the user leaves the first position is that, for example, the mobile terminal is disconnected according to whether the connection between the mobile terminal and bluetooth of the vehicle is disconnected, where the mobile terminal may take a time when the connection with bluetooth of the vehicle is disconnected as a time when the user leaves the first position; for another example, whether the moving speed of the mobile terminal is significantly reduced may be taken as the time when the user leaves the first location, and the specific manner in which the mobile terminal detects that the user leaves the first location is not specifically limited.
Taking a target object as a vehicle as an example, taking a parking lot as a place where a first position is located, wherein the first position is a parking place where the vehicle is located, after a user can park the vehicle in the parking place, the user can leave the parking lot by taking an elevator, and the mobile terminal detects whether the user leaves the parking lot or not, for example, the mobile terminal can detect whether the altitude of the mobile terminal changes, wherein the moment when the mobile terminal detects the change of the altitude of the mobile terminal can be used as the moment when the user leaves the parking lot; for another example, the mobile terminal may detect a change in the number of wireless devices, and the time when the number of wireless devices is 0 may be regarded as the time when the user leaves the parking lot, and the manner in which the mobile terminal detects that the user leaves the location of the first location is not particularly limited.
It can be understood that whether the user leaves the first location and the detection manner of whether the user leaves the location where the first location is located can be set according to a specific application scenario.
In some embodiments of the present application, after detecting whether the user leaves the first location, the mobile terminal may collect the wireless signal and the first direction information of the user in real time, so that the first state information corresponding to each collection point may be obtained to include the first wireless signal information and the first direction information.
In some embodiments, the step 120 is related to the step, where it is detected that the user needs to return to the first location, the second state information may be acquired by the mobile terminal, where the second state information may include second wireless signal information. Specifically, the second wireless signal information may include a device identifier of the wireless device in the location detected by the mobile terminal, and may also include a signal strength of the wireless device in the location.
The step 130 and the step 140 are related to the first state information and the acquisition points in a one-to-one correspondence, and because the first state information includes the first wireless signal information, different wireless signal ranges can be calibrated by different first state information, and the position of each acquisition point can be calibrated by the wireless signal range calibrated by the first state information. The second state information also comprises second wireless signal information, and the position corresponding to the acquisition time of the second state information can be calibrated through the wireless signal range calibrated by the second wireless signal information.
Then, by determining the similarity between the second state information and the first state information of each acquisition point, the coincidence degree of the wireless signal range calibrated by the first state information and the wireless signal range calibrated by the second wireless signal information can be determined. The higher the similarity is, the larger the contact ratio is, and the closer the distance between the acquisition point and the position corresponding to the acquisition time of the second state information is. Therefore, the acquisition point with the greatest similarity can be regarded as the first target acquisition point.
Finally, referring to step 150, the first target movement direction may be determined and displayed by the first target position and the corresponding first status information. For example, the first direction information of each acquisition point is included in the first state information, that is, the moving direction of the user at each acquisition point may be included in the first state information, and thus, the opposite direction of the moving direction of the acquisition point corresponding to the first target position may be regarded as the first target moving direction.
Fig. 2 is a schematic diagram of displaying navigation information according to an embodiment of the present application, and in combination with fig. 2, a plurality of acquisition points are shown in fig. 2. For example, acquisition point 201, and the first target location corresponds to acquisition point 204. The first target movement direction is as shown in fig. 2 as direction 202.
Optionally, the mobile terminal may further display a reference path and a current moving direction of the user, and continuing to combine with fig. 2, where the reference path includes a plurality of acquisition points connected in sequence, and the direction 203 may represent a forward direction of the current user, so that the user may conveniently know an adjustment angle of the current forward direction.
According to the embodiment of the application, the similarity between the second state information and the first state information of each acquisition point is determined by acquiring the first state information of the user from the first position to the second position and acquiring the second state information under the condition that the user needs to return to the first position, so that the acquisition point with the maximum similarity can be determined as the first target position; and determining and displaying a first target moving direction according to the first target position and the corresponding first state information. In this way, the user can find the first position according to the direction of the first target movement direction.
In some optional embodiments, in a case that the mobile terminal returns to the location, the first acquired information may be acquired specifically: acquiring first acquisition information according to a first preset acquisition frequency; and updating the first navigation information according to the first acquired information. In this way, the first navigation information displayed by the mobile terminal can be updated in real time, so that the reliability of the first navigation information displayed by the mobile terminal is improved.
In order to clearly illustrate the navigation method provided by the embodiment of the present application, a specific calculation method of the target acquisition point is described below with a specific example. Specifically, in the case that the user returns to the first location from the second location, after acquiring the second status information, the method further includes: determining a first signal identifier and corresponding signal strength in each piece of first wireless signal information, and a second signal identifier and corresponding signal strength in each piece of second wireless signal information; determining the arrangement order of the first signal identification sequences according to the signal intensity of each first signal identification; and determining the arrangement order of the second signal identification sequences according to the signal strength of each second wireless signal identification.
Based on the above, the second signal identification sequences and the first signal identification sequences can be conveniently compared and analyzed to determine the intersection, and the similarity of the second state information and the first state information of each acquisition point is determined based on the signal identifications included in the intersection and the corresponding signal strengths.
In some embodiments, determining the similarity of the second state information to the first state information of the respective acquisition points comprises: determining a third signal identifier, wherein the third signal identifier is an intersection of the first signal identifier and the second signal identifier; and calculating the similarity of the second state information and the first state information of each acquisition point according to the number of the third signal identifications, the arrangement order of each third signal identification in the first signal identification sequence and the arrangement order of each third signal identification in the second signal identification sequence.
The number of the third signal identifiers may be 0 or one or more. For example, the first signal identifier sequence includes first signal identifiers {1a,2b,3c,5f }, the second signal identifier sequence includes second signal identifiers {2b,4d,5f,6e }, and the intersection of the second signal identifiers with the first signal identifiers {2b,5f }, that is, the third signal identifiers have two. Wherein the arrangement order of the third device identifications "2b" in the first signal identification sequence is 2, and the second arrangement order of the third device identifications "2b" in the second signal identification sequence is 1; the first arrangement order of the third device identification "5f" in the first signal identification sequence is 4, and the second arrangement order of the third device identification "5f" in the second signal identification sequence is 3.
In the embodiment of the application, the larger the intersection between the signal sequences is, and the more the arrangement order is converged, the more the coverage ranges of the corresponding wireless signals between the two signal sequences are similar, and correspondingly, the higher the similarity of the state information corresponding to the two signal sequences is. By calculating the intersection between the signal sequences and the arrangement order of each third signal identifier in the intersection in different sequences, the accuracy of the similarity between the second state information and the first state information of each acquisition point can be effectively improved.
In some embodiments, the similarity between the second state information and the first state information of each acquisition point is calculated according to the number of third signal identifications, the arrangement order of each third signal identification in the first signal identification sequence, and the arrangement order of each third signal identification in the second signal identification sequence, and the following steps can be specifically referred to: acquiring a position distance between a first arrangement order of each third signal identifier in the first signal identifier sequence and a second arrangement order of the third signal identifiers in the second signal identifier sequence; and determining the similarity between the second state information and the first state information of each acquisition point according to the number and the position distance of the third signal identifiers.
Continuing taking the example that the first signal identification sequence includes first signal identifications {1a,2b,3c,5f }, the second signal identification sequence includes second signal identifications {2b,4d,5f,6e }, the intersection of the second signal identifications and the first signal identifications includes {2b,5f }, at this time, the number of third device identifications is 2, and the third device identifications are "2b" and "5f" respectively.
The first arrangement order of the third device identifiers 2b in the first signal identifier sequence is 2, the second arrangement order of the third device identifiers 2b in the second signal identifier sequence is 1, and the difference value between the first arrangement order and the second arrangement order is the position distance, wherein the position distance corresponding to the third device identifiers 2b is 1; the first arrangement order of the third device identifiers '5 f' in the first signal identifier sequence is 4, the second arrangement order of the third device identifiers '5 f' in the second signal identifier sequence is 3, and the difference value between the first arrangement order and the second arrangement order is the position distance, wherein the position distance corresponding to the third device identifiers '5 f' is 1.
In some embodiments, the greater the number of third signal identifications included in the intersection between the first signal identification sequence and the second signal identification sequence, the greater the similarity between the first state information and the second state information. If the position distance corresponding to each third signal identifier in the intersection is smaller, the similarity between the first state information and the second state information can be improved. The similarity between the second state information and the first state information of each acquisition point is determined by calculating the number of third signal identifications in the intersection between the signal sequences and the arrangement order of each third signal identification in the intersection in different sequences, so that the reliability of the similarity can be effectively improved.
Specifically, the first similarity between the second state information and each of the first state information may be determined based on the number of third signal identifications, and the second similarity between the second state information and each of the first state information may be determined based on the position distance corresponding to each of the third signal identifications in the intersection. And determining the similarity between the second state information and each first state information according to the first similarity and the second similarity. For example, the similarity between the second state information and each of the first state information may be calculated by summing the first similarity and the second similarity; for another example, the weights of the first similarity and the second similarity may be set, and the similarity between the second state information and each of the first state information may be calculated by means of weighted summation.
In some optional embodiments, the similarity between the second state information and the first state information of each acquisition point is determined according to the number and the position distance of the third signal identifiers, and the similarity may be calculated by referring to a similarity calculation formula based on a preset, where the similarity calculation formula is shown in formula (1).
Taking the total number of the first state information as I as an example, the total number of the first signal identification sequences is also I. The first signal identification sequence corresponding to the ith first state information comprises m signal identifications in total, and the second signal identification sequence corresponding to the second state information comprises n signal identifications in total.
In the formula (1), m is the number of first device identifications in the ith first signal identification sequence, n is the number of second device identifications in the second signal identification sequence, a is the number influence parameter in the preset sensitivity influence parameters, a k For the first k device identifications in the ith first signal identification sequence and the first k device identifications in the second signal identification sequenceAnd the number of the third device identifiers in the intersection, wherein k sequentially takes values from 1 to min (m, n).
Taking k=4 as an example, the first four first device identifiers in the first signal identifier sequence are {1a,2b,3c,5f }, respectively, the first four second device identifiers in the second signal identifier sequence are {2b,4d,5f,6e }, respectively, and the intersection is {2b,5f }, at this time, a 4 ＝2。
In the formula (1), b is a position distance influence parameter among the preset sensitivity influence parameters, b k The ratio of the sum of the corresponding location distances to k is identified for each third device.
Continuing with k=4 as an example, the first four first device identifications in the first signal identification sequence are {1a,2b,3c,5f } respectively, and the first four second device identifications in the second signal identification sequence are {2b,4d,5f,6e } respectively, with intersections of {2b,5f }. The first arrangement order of the third device identifier "2b" in the first signal identifier sequence is 2, the second arrangement order of the third device identifier "2b" in the second signal identifier sequence is 1, and the difference value between the first arrangement order and the second arrangement order is the position distance, that is, the position distance corresponding to the third device identifier "2b" is 1; the first arrangement order of the third device identifier "5f" in the first signal identifier sequence is 4, the second arrangement order of the third device identifier "5f" in the second signal identifier sequence is 3, and the difference between the first arrangement order and the second arrangement order is the position distance, that is, the position distance corresponding to the third device identifier "5f" is 1. The sum of the position distances corresponding to the third device identifications is 2, and the ratio of the sum of the position distances corresponding to the third device identifications to k=4 can be calculated to obtain b 4 ＝0.5。
In some embodiments, the preset sensitivity influencing parameters include a number influencing parameter a and a position distance influencing parameter b, wherein a > 0, b > 0, a+b=1. Specifically, for example, a and b take values between [0,1], where a and b take values that determine the sensitivity of the mobile terminal to the wireless device. For example, a takes a value of 0.8 and b takes a value of 0.2. After each navigation is completed, the user can feed back the sensitivity of the navigation. The values of a and b can be adjusted according to the sensitivity of the user feedback. For example, the user feedback path may react slowly by increasing the value of b by 0.05 each time until the value of b is 0.95, and the values of a and b are not particularly limited here, provided that the user feedback path reacts too quickly to decrease the value of b by 0.05 each time until the value of b is 0.5.
According to the embodiment of the application, after the similarity between the second state information and the first state information of each acquisition point is determined according to the number and the position distance of the third signal marks, the acquisition point with the largest similarity can be used as the first target position, and then the first target moving direction is determined and displayed according to the first target position and the corresponding first state information, so that the user is guided to search the target object. Because the whole navigation information generation process does not need to depend on satellite positioning signals, particularly in an indoor environment, the user can be rapidly and accurately guided to return to the first position under the condition of weak satellite signal positioning can be effectively avoided.
In some embodiments, in order to improve the reliability of the navigation information, after determining the similarity between the second state information and the first state information of each acquisition point, in combination with the flowchart of another method for generating the navigation information shown in fig. 3, the present application may further include the following steps.
In step 301, under the condition that the similarity between the second state information and the first state information of each acquisition point is smaller than the preset similarity, wireless device information in the target location is obtained, and the wireless device information includes location information of each wireless device in the target location.
Specifically, the wireless device information includes location information of each wireless device in the venue.
For example, when the similarity between the first detection information and each second detection information is smaller than the preset similarity, it is indicated that the current position of the user is far from the acquisition point included in the path information, and the user needs to navigate to the vicinity of the acquisition point.
The device information of the wireless device in the location may be configured in advance in the mobile terminal, or may be obtained by the mobile terminal requesting the server in the location, and the specific manner of obtaining the device information of the wireless device in the location is not limited.
Step 302, determining the distance between each acquisition point and a third position according to the position information, each first wireless signal information and each second wireless signal information, wherein the third position is a position corresponding to the second state information.
Specifically, the location information corresponding to the first device identifier included in each piece of first wireless signal information and the location information corresponding to the second device identifier included in the second wireless signal information may be determined based on the location information. Thus, the distance between each acquisition point and the third position can be determined.
In order to improve the calculation speed, a fourth device identifier of the wireless device corresponding to the maximum signal intensity in the first wireless signal information and a fifth device identifier of the wireless device corresponding to the maximum signal intensity in the second wireless signal information may be obtained respectively, a distance between the fifth device identifier and each fourth location identifier is determined according to the location information of the fifth device identifier and the location information of each fourth location identifier, and a distance between the fifth device identifier and each fourth location identifier is determined as a distance between the third location and each acquisition point.
Step 303, determining the acquisition point with the smallest distance as a second target position;
Step 304, determining and displaying the second target moving direction according to the second target position and the corresponding first state information.
According to the embodiment of the application, the mobile terminal can generate the second navigation information based on the first detection information acquired by the current position of the user and the position information of each wireless device in the place, so that the user can be navigated to the vicinity of the acquisition point included in the path information, and accurate navigation information can be provided for the user, so that the user can find the first position.
