[0057] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0058] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0059] In Example 1, this embodiment provides an information guidance method for a smart campus, which is used in a smart campus system. The smart campus system includes a cloud server, multiple road sign guidance terminals, and multiple user terminals. The cloud server is connected to the multiple road sign guidance terminals and the multiple user terminals respectively;

[0060] The user terminal is used to initiate a new student registration request, and the cloud server is used to respond to the new student registration request to generate registration feedback information. Each user terminal corresponds to a student ID;

[0061] In this embodiment, the user terminal may be a smart mobile terminal such as a smart bracelet, a smart watch, or a mobile phone.

[0062] In this embodiment, the road sign guidance terminal is set at any scene location on campus. Each road sign guidance terminal includes a touch display screen, a camera, a processor and a communication module. In the road sign guidance terminal, the processor is respectively connected to the touch display screen, the camera, and the communication module. The processor exchanges data with the cloud server through the communication module.

[0063] like Figure 1 As shown, the method includes:

[0064] Step S100: Initializing virtual campus map information in the cloud server, where the virtual campus map information includes multiple virtual venue nodes;

[0065] In this embodiment, the virtual site node is a scene location on campus, for example, it can be various colleges, teaching buildings, laboratories, libraries, dormitories, gymnasiums, canteens, parking lots and other places, and each virtual site node has a corresponding three-dimensional model in the virtual campus map information;

[0066] Each virtual venue node has a corresponding node ID. When the virtual campus map information is displayed in a three-dimensional manner, each virtual venue node has a corresponding three-dimensional spatial coordinate point; when the virtual campus map information is displayed in a two-dimensional manner, each virtual venue node has a corresponding two-dimensional plane coordinate point;

[0067] In this embodiment, each spatial three-dimensional coordinate point has a corresponding plane two-dimensional coordinate point. The virtual campus map information corresponds to the preset campus distribution plan, and the plane two-dimensional coordinate points in the preset campus distribution plan are mapped according to the virtual venue nodes, that is, based on the same virtual venue nodes, the plane two-dimensional coordinate points and the spatial three-dimensional coordinate points have a mapping conversion relationship, thereby realizing the conversion between plane and three-dimensional modes.

[0068] In this embodiment, the new student registration request is triggered by the user terminal. For example, when a new student enters school, after registering his / her identity information using the user terminal, the student's name and ID number are packaged into the new student registration request;

[0069] Step S200: When the cloud server receives a new student registration request initiated by a user terminal, the cloud server generates registration feedback information based on the student information; wherein the new student registration request includes name and ID number.

[0070] The cloud server generates registration feedback information based on student information, including:

[0071] Step S210: Based on the preset student information database, matching the corresponding student information according to the ID card number;

[0072] Step S220: extracting the college name and accommodation information from the student information;

[0073] Step S230: matching the corresponding address text according to the college category in the preset freshman registration location table;

[0074] Step S240: finding a corresponding virtual venue node according to the address text as a first target venue node and adding the first target venue node to the registration feedback information;

[0075] Step S250: If the accommodation identifier is true, find the corresponding virtual venue node as the second target venue node according to the accommodation information and add the second target venue node to the registration feedback information. At the same time, extract the dormitory building number, floor number, room number, and bed number from the accommodation information and add them to the registration feedback information.

[0076] Step S260: If the accommodation mark is false, a non-accommodation mark is added to the registration feedback information.

[0077] In this embodiment, the user terminal receives registration feedback information and displays the student's registration location or dormitory building in combination with the virtual campus map information. By displaying the registration location or dormitory building related to the student, the guidance for new students when they enter school is more personalized, avoiding the confusion of displaying the registration locations of multiple colleges on the map at the same time, reducing the situation of new students getting lost when reporting, and improving the registration efficiency of new students when they enter school.

[0078] In the preset student information database, each student is indexed by a unique ID number to obtain the corresponding student information. For example, the student information includes name, student ID, contact information, emergency contact information, accommodation information, year of enrollment, major name, and college name. For example, the contact information is a mobile phone number, email address, etc., the emergency contact information is the mobile phone number of the emergency contact, and the accommodation information includes the dormitory building number, floor number, room number, and bed number.

[0079] In the preset freshman registration location table, each college category corresponds to an address text, and the registration location of the college can be determined based on the address text, so that students from each college can be matched to the corresponding registration location in a timely manner.

[0080] Step S300: When the cloud server receives the first guidance request initiated by the user terminal, the cloud server performs a first adaptive guidance process according to the check-in status and the registration feedback information to obtain a first guidance feedback information set; wherein the first guidance request includes the first real-time location information corresponding to the user terminal, the student ID, and the first location to be guided, and the first guidance feedback information set is used to send the user terminal to display the guidance result;

[0081] The cloud server performs first adaptive guidance processing according to the check-in status and the registration feedback information to obtain a first guidance feedback information set, specifically including:

[0082] Step S310: If the check-in status is the checked-in mark, a path is planned with the first real-time location information as the starting point and the first location to be guided as the end point to obtain a first visiting guidance path, and the first visiting guidance path is added to the first guidance feedback information set;

[0083] Step S320: If the check-in status is the first non-check-in mark, a path is planned with the first real-time location information as the starting point and the first target site node as the end point to obtain a first prompt guidance path; if there is a second target site node, the path is planned with the first target site node as the starting point and the second target site node as the end point to obtain a second prompt guidance path, and both the first prompt guidance path and the second prompt guidance path are added to the first guidance feedback information set; if there is no second target site node, the first prompt guidance path is added to the first guidance feedback information set;

[0084] Step S330: if the check-in status is the second non-check-in mark, a path is planned with the first real-time location information as the starting point and the second target site node as the end point to obtain a third prompt guidance path, and the third prompt guidance path is added to the first guidance feedback information set;

[0085] In this embodiment, the checked-in mark indicates that the new student has checked in and has arrived at the dormitory building, the first not checked-in mark indicates that the new student has not checked in and has not arrived at the dormitory building, and the second not checked-in mark indicates that the new student has checked in but has not arrived at the dormitory building.

[0086] In each path planning, it specifically includes: determining the starting point and the end point; based on the shortest path algorithm, determining the path weight according to the distance between two adjacent path nodes in the virtual campus map information, and screening out the path node combination corresponding to the minimum sum of the path weights, so as to determine the path planning result; it should also be noted that the shortest path algorithm mentioned in this application is a prior art, for example, the Dijkstra algorithm or the A* algorithm can be used.

[0087] In this embodiment, each path planning result includes at least one path segment, and each path segment is composed of two or more path nodes. Exemplarily, each path node corresponds to a plane two-dimensional coordinate point, and the path node can be a scene location on campus, such as a teaching building, library, canteen, dormitory building, gymnasium, campus gate, campus central square, passage corner, etc.

[0088] In this embodiment, when the new student does not carry a user terminal, in order to enable the road sign guidance terminal to provide the new student with a more personalized guidance experience, the method further includes:

[0089] Step S400: When the cloud server receives the second guidance request initiated by the landmark guidance terminal, the cloud server performs a second adaptive guidance process according to the check-in status and the registration feedback information to obtain a second guidance feedback information set; wherein the second guidance request includes the second location information corresponding to the landmark guidance terminal, the second location to be guided, the student ID, and the user screenshot image;

[0090] In this embodiment, the second guidance request is triggered by the user to be guided clicking a request control on the touch display screen, and the touch display screen is used to display the campus guidance interface;

[0091] The function of using a touch display screen to display a campus guidance interface in this application is a prior art. Exemplarily, a first display area, a second display area, and a third display area are set in the campus guidance interface, wherein the first display area is used to display virtual campus map information, the second display area is used to display a location search box, and the third display area is used to display a text input box and a request control, the text input box is used to obtain the name of the user to be guided, and the request control is used to click to trigger the generation of a second guidance request, and the second location to be guided can be determined by the user to be guided clicking in the first display area, and the second location to be guided can also be determined by the user to be guided entering a place name in the location search box, which is not specifically limited here.

[0092] The cloud server performs the second adaptive guidance processing according to the check-in status and the registration feedback information to obtain the second guidance feedback information set, specifically including:

[0093] Step S410: Initializing a second guidance feedback information set;

[0094] Step S420: Combining the student ID and the user screenshot image to identify the new student;

[0095] In the process of identifying new students by combining student ID and user screenshot images, the following are specifically included:

[0096] Step S421: Based on the pre-stored student face database, the corresponding face reference features are matched according to the student ID; wherein the face reference features are obtained by extracting features from pre-collected student face images, and the feature extraction method is an existing technology, such as a method based on geometric features, a method based on global information, a method based on a histogram of oriented gradients (HOG), a method based on Haar features, and the like.

[0097] In the pre-stored student face database, each student ID corresponds to a facial reference feature.

[0098] Step S422: capturing the user's screenshot image to obtain a face image to be compared;

[0099] Step S423: extracting features of the face image to be compared using the same feature extraction method as the face reference feature to obtain the face feature to be compared;

[0100] Step S424: Calculate the similarity between the reference face feature and the face feature to be compared. If the similarity is greater than or equal to a preset similarity threshold, it is determined that the new identity recognition is successful, otherwise the new identity recognition fails.

[0101] It should also be noted that calculating similarity is a prior art, and the specific calculation process does not fall within the scope of protection of this application.

[0102] Step S430: if the new student's identity is successfully identified, a second guidance feedback information set is generated according to the registration status and registration feedback information;

[0103] In generating the second guidance feedback information set according to the check-in status and the registration feedback information, specifically including:

[0104] Step S431: if the check-in status is the checked-in mark, a second real-time location information is used as a starting point and a second location to be guided is used as an end point to perform path planning to obtain a second visiting guidance path, and the second visiting guidance path is added to the second guidance feedback information set;

[0105] Step S432: if the check-in status is the first non-check-in mark, the second real-time location information is used as the starting point and the first target site node is used as the end point to perform path planning to obtain a fourth prompt guidance path; if the second target site node exists, the first target site node is continued to be used as the starting point and the second target site node is used as the end point to perform path planning to obtain a second prompt guidance path, and both the second prompt guidance path and the fourth prompt guidance path are added to the second guidance feedback information set; if the second target site node does not exist, the fourth prompt guidance path is added to the second guidance feedback information set;

[0106] Step S433: if the check-in status is the second non-check-in mark, a path is planned with the second real-time location information as the starting point and the second target site node as the end point to obtain a fifth prompt guidance path, and the fifth prompt guidance path is added to the second guidance feedback information set;

[0107] Step S440: If the new student identity recognition fails, a second visiting guidance path is obtained by performing path planning with the second real-time location information as the starting point and the second location to be guided as the end point, and the second visiting guidance path is added to the second guidance feedback information set;

[0108] In this embodiment, the first real-time location information and the second real-time location information are both GPS positioning coordinates.

[0109] In this embodiment, in order to further improve the guidance efficiency, Figure 2 As shown, the method also includes:

[0110] Step S500: filtering non-overlapping areas by combining the path record information set and the first guidance feedback information set through the cloud server, and setting guidance warning marks according to deviations of the non-overlapping areas;

[0111] In this embodiment, the path record information set includes a plurality of path record information, and the path record information is uploaded to the cloud server by the user terminal after the guidance is completed, and the path record information is used to record the two-dimensional coordinate points of the plane that the user has walked during the guidance;

[0112] In filtering the non-overlapping area by combining the path record information set and the first guidance feedback information set through the cloud server, specifically including:

[0113] Step S510: traverse the first guidance feedback information set in sequence, and find the path record information corresponding to the currently traversed path planning result from the path record information set;

[0114] Step S520: screening the currently traversed path planning result and the two-dimensional coordinate points in the path record information that are not overlapped. If there are two-dimensional coordinate points in the plane that are not overlapped, the two-dimensional coordinate points are divided into the same area based on the position proximity as the connected area condition to obtain non-overlapping areas. If there are no two-dimensional coordinate points in the plane that are not overlapped, no processing is performed.

[0115] In this embodiment, the non-overlapping relationship specifically indicates that there are planar two-dimensional coordinate points in the path record information that are not included in the path planning result. It should also be noted that those skilled in the art should understand that the first guidance feedback information set here includes multiple path planning results, and the path record information set contains path record information corresponding to any one of the path planning results.

[0116] In setting guidance and warning signs according to the deviation of non-overlapping areas, it specifically includes:

[0117] Step S530: if there is any non-overlapping area, the deviation influence of each path segment is calculated respectively. If the deviation influence of any path segment is greater than the preset influence threshold, the deviation times of the path segment are added by 1, otherwise the deviation times are not updated. If there is no non-overlapping area, no processing is performed.

[0118] In this embodiment, the deviation influence degree is specifically expressed as:

[0119]

[0120] where θ i represents the deviation influence on the i-th path segment, cnt0(i) represents the number of plane coordinate points contained in the non-overlapping area of ​​the i-th path segment, and cnt1(i) represents the number of plane coordinate points contained in the overlapping area of ​​the i-th path segment;

[0121] In this embodiment, when cnt1(i) is 0, the default value is θ i The value is the preset impact threshold.

[0122] In this embodiment, each overlapping area is an area range formed by the planar two-dimensional coordinate points included in the corresponding path planning result.

[0123] Exemplarily, in combination with FIG. 3(a) and FIG. 3(b), taking a curved path segment as an example, the white part in FIG. 3(a) belongs to the non-overlapping area (area at A), which is the part outside the range corresponding to the path planning result; the black part in FIG. 3(a) belongs to the overlapping area (area at B) and corresponds to the path planning result. L1 in FIG. 3(b) is the path recording information corresponding to the user to be guided in the curved path segment. The number of plane coordinates recorded by the user to be guided in area A is the number of plane coordinate points contained in the non-overlapping area of ​​the curved path segment, and the number of plane coordinates recorded by the user to be guided in area B is the number of plane coordinate points contained in the overlapping area of ​​the curved path segment.

[0124] Step S540: if the number of deviations of any path segment is less than the preset number, no processing is performed; if the number of deviations of any path segment is greater than or equal to the preset number, a guidance warning flag is set for the path segment in the guidance warning table;

[0125] In this embodiment, the number of deviations of each path segment is reset to 0 according to a preset period. For example, the preset period is set to a value such as 3 months, half a year or a year, which is not specifically limited here.
