[0036] The following describes exemplary embodiments of the present application in conjunction with the accompanying drawings. Various details of the embodiments of the present application are included to facilitate understanding, and they should be considered merely exemplary. Therefore, those of ordinary skill in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Similarly, descriptions of well-known functions and structures are omitted in the following description for clarity and conciseness.

[0037] It should be noted that the in-station passage of a subway station is located between various entrances and exits of the subway station. It is a road that does not require passing through a turnstile, does not require additional payment, and can be freely passed through. If people can make full use of the in-station passage of the subway station during walking, the purpose of saving the path can be achieved, and the original journey that needs to cross the road can be changed to walking through the in-station passage of the subway station, increasing the safety of passage. Therefore, how to generate a passable road model in the subway station has become an urgent problem to be solved.

[0038] Based on the above problems, the present application discloses a method for generating a passable road model in a subway station. By obtaining the connection relationship between various entrances and exits in the subway station and combining with the plane structure diagram of the subway station, a passable road model of the subway station is generated. The following describes the method for generating a passable road model in a subway station according to an embodiment of the present application with reference to the accompanying drawings.

[0039] Figure 1 This is a flowchart of a method for generating a passable road model in a subway station according to an embodiment of the present application. As Figure 1 shown, the method for generating a passable road model in the subway station includes the following steps:

[0040] Step 101, obtain the subway station identifier of the current location of the electronic device.

[0041] In one implementation, it is assumed that the method for generating a passable road model in a subway station according to an embodiment of the present application can be applied to an electronic device, and a collection application program is installed on the electronic device. The user can use the collection application program to collect and record the connection relationship between the entrances and exits in the subway station.

[0042] As one implementation, the present application can set a search bar in the interface of the collection application program. When it is necessary to obtain the subway station identifier, the subway station identifier that best meets the search conditions can be displayed to the user according to the search conditions in the search bar. The user can select the most suitable subway station identifier according to the actual situation to obtain the corresponding subway station identifier. Among them, the search content can be a keyword or the street name corresponding to the subway station.

[0043] For example, when it is necessary to obtain the subway station identifier, enter "Chenjiaci Street" in the search bar and search, and the identifier of Chenjiaci Subway Station can be obtained. After the user selects the identifier of Chenjiaci Subway Station, the electronic device can obtain the identifier of Chenjiaci Subway Station based on the user's selection operation.

[0044] Step 102: Obtain the floor plan of the subway station according to the subway station identifier.

[0045] As an implementation method, the floor plans of subway stations in each province (or city) can be obtained in advance from the subway station map library, the data sets are divided according to the province (or city), and the floor plans of the subway stations are stored in their respective corresponding data sets.

[0046] Optionally, when obtaining the identifier of the subway station where the electronic device is currently located, the city to which the subway station belongs can be determined according to the subway station identifier, and the floor plan of the subway station can be obtained from the pre-stored data set according to the city and the subway station identifier.

[0047] Step 103: Obtain the connection relationship between N entrances and exits in the subway station according to the operation information for making subway passage events on the collected application interface; wherein, the collected application is installed on the electronic device; N is a positive integer.

[0048] For example, there are three entrances and exits A, B, and C in the subway station. There is a "Make Subway Passage" control on the collected application interface. The user triggers the "Make Subway Passage" control to perform the operation of making the subway passage. According to the actual situation, it is determined that only A to B is connected. The user inputs the connection relationship of the entrances and exits into the collected application and ends the operation of making the subway passage; in this way, the operation information of the user on the collected application interface can be obtained, and the connection relationship between N entrances and exits in the subway station can be obtained.

[0049] Step 104: Generate a passable road model of the subway station according to the floor plan and the connection relationship between N entrances and exits.

[0050] As an implementation method, first default that all entrances and exits are connected to each other, obtain the passage roads between each entrance and exit according to the floor plan of the subway station, and when the connection relationship between the entrances and exits is determined, the corresponding passage roads can be selected to generate the passable road model of the subway station.

[0051] As an example, there are three entrances and exits A, B, and C in the subway station. The passage roads of A-B, B-A, C-A, A-C, C-B, and B-C are obtained according to the floor plan of the subway station. When it is determined that only A to B is connected, the passable road model of the subway station can be generated according to the passage road of A-B.

[0052] As another implementation, by default, there is no connection between each entrance and exit. After determining the connection relationship between the entrances and exits, the passage roads between the corresponding entrances and exits are obtained according to the floor plan of the subway station, and the passable road model of the subway station is generated based on the passage roads between the corresponding entrances and exits.

[0053] As an example, there are three entrances and exits A, B, and C in the subway station. When it is determined that only A is connected to B, the passage road from A to B is obtained according to the floor plan of the subway station, and the passable road model of the subway station is generated based on the passage road from A to B.

[0054] It should be noted that there are many application scenarios for the passable road model of the subway station. As an example, the generated passable road model inside the subway station is combined with a walking navigation program. When the user needs to perform walking navigation, the walking navigation program generates a route map, and the route includes the part of the in-station passage of subway station F. For example, it is shown on the route map as: Enter from entrance A of subway station F - Leave from entrance B of subway station F.

[0055] According to the method for generating the passable road model inside the subway station of the present application, by obtaining the subway station identifier of the current location of the electronic device, the information confirmation of the subway station is realized, providing basic information for subsequent route acquisition and ensuring the accuracy of the generated road model; by obtaining the floor plan, the purpose of generating the passable road model according to the connection situation is realized, reducing the error between the acquisition result and the actual situation; a collection application program can be provided for the user, and the user determines the connection relationship between each entrance and exit by operating the collection application program. Social personnel can be mobilized for local collection, so that the collection process does not require complex professional knowledge, only the collection application program needs to be operated, and there is no need for heavy collection equipment. By combining the passable road model with the downstream walking navigation program, the user's understanding of the passage situation inside the subway station is realized, enabling the user to make full use of the in-station passage of the subway station during walking, achieving the purpose of saving the path, and changing the originally required road-crossing journey to walking through the in-station passage of the subway station, increasing the traffic safety.

[0056] It should be noted that the subway station identifier can be obtained by obtaining the location information of the electronic device, such as Figure 2 shown, Figure 2 FIG. is a flowchart of another method for generating a passable road model inside a subway station provided by an embodiment of the present application. The method includes the following steps.

[0057] Step 201, when entering the collection application program, obtain the current location information of the electronic device.

[0058] It should be noted that there are many methods to obtain the current location information of an electronic device. For example, GPS (Global Positioning System), or WIFI (Wireless Communication Technology) hotspot positioning. It can be understood that there are many methods to obtain the current location information of an electronic device. Two examples are given below to describe the specific methods of obtaining the current location information of an electronic device:

[0059] As an example, GPS provides navigation functions based on 24 orbiting satellites in space. Through the built-in GPS signal receiver of a mobile device, it is possible to directly read satellite data to calculate the location. The positioning accuracy is between 2 meters and 100 meters.

[0060] As another example, WIFI hotspot positioning is performed by detecting the list of wireless routers (including public hotspots and private wireless routers) that can be detected on a mobile device.

[0061] Step 202, when it is determined that the current location of the electronic device is a subway station based on the current location information, obtain the subway station identifier of the current location of the electronic device.

[0062] As an implementation method, determine the location coordinates of each subway station, set a preset threshold, calculate the straight-line distance between the current location information of the electronic device and the location coordinates of each subway station according to the current location information of the electronic device. If the straight-line distance between the current location information of the electronic device and the location coordinates of a certain subway station is less than or equal to the preset threshold, it can be considered that the electronic device is currently located within that certain subway station. At this time, the subway station identifier of that certain subway station can be obtained; if the straight-line distance between the current location information of the electronic device and the location coordinates of a certain subway station is greater than the preset threshold, it can be considered that the electronic device is not currently located within that certain subway station, and there is no need to obtain the subway station identifier of that certain subway station.

[0063] For example, set the preset threshold to 50 meters. According to the current location information of the electronic device, determine that the electronic device is located at point M, obtain the location coordinates of each subway station, and determine the distance between the current location information of the electronic device and the location coordinates of each subway station. Among them, assume that a certain subway station is located at point N, and the straight-line distance from point M to point N is L, and L is 30 meters, and L is less than or equal to the preset threshold, then the subway station identifier of that certain subway station can be obtained.

[0064] Step 203, obtain the floor plan of the subway station according to the subway station identifier.

[0065] In the embodiments of the present application, step 203 can be implemented in any one of the embodiments of the present application. The embodiments of the present application do not make any limitations on this and will not be elaborated further.

[0066] Step 204: Obtain the connectivity relationship between N entrances and exits in the subway station according to the operation information of making subway passage events on the collected application interface; wherein, the collection application is installed on the electronic device; N is a positive integer.

[0067] In the embodiments of the present application, step 204 can be implemented in any one of the embodiments of the present application, and the embodiments of the present application do not limit this and will not elaborate further.

[0068] Step 205: Generate a passable road model of the subway station according to the plane structure diagram and the connectivity relationship between N entrances and exits.

[0069] In the embodiments of the present application, step 205 can be implemented in any one of the embodiments of the present application, and the embodiments of the present application do not limit this and will not elaborate further.

[0070] According to the method for generating a passable road model in the subway station of the present application, by obtaining the current position information of the electronic device, the determination of the position of the subway station is realized, which provides a guarantee for successfully obtaining the plane structure diagram of the subway station in the subsequent process, and ensures the successful generation of the passable road model of the subway station.

[0071] It should be noted that Figure 3 is a flowchart of another method for generating a passable road model in the subway station provided by the embodiments of the present application.

[0072] As Figure 3 shown, the method for generating a passable road model in the subway station includes the following steps:

[0073] Step 301: Obtain the subway station identifier of the current location of the electronic device.

[0074] In the embodiments of the present application, step 301 can be implemented in any one of the embodiments of the present application, and the embodiments of the present application do not limit this and will not elaborate further.

[0075] Step 302: Obtain the plane structure diagram of the subway station according to the subway station identifier.

[0076] In the embodiments of the present application, step 302 can be implemented in any one of the embodiments of the present application, and the embodiments of the present application do not limit this and will not elaborate further.

[0077] Step 303: Obtain the identifiers of N entrances and exits included in the subway station.

[0078] As an example, through the plane structure diagram of the subway station, identify the number, name, and positional relationship of the entrances and exits of the subway station.

[0079] It should be noted that when there are differences between the obtained entrance and exit information of the subway station and the actual situation, the entrance and exit of the subway station can be retrieved again through the automatic modification instruction. If there are still differences between the obtained entrance and exit information of the subway station and the actual situation after the retrieval, the entrance and exit information of the subway station can be entered or deleted through the manual modification instruction.

[0080] In one implementation, the name of each entrance and exit of the subway station can be modified through the manual modification instruction.

[0081] In another implementation, the operation of adding remarks to each entrance and exit of the subway station can be realized through the manual modification instruction. Among them, the remarks can include the peak time of each entrance and exit, or the business situation around each entrance and exit.

[0082] Step 304: Display the identifiers of N entrances and exits in the first area 1 of the collection application interface.

[0083] Step 305: In response to the selection instruction for the identifier of the i-th entrance and exit in the first area and the operation information for making the subway passage event, display the identifiers of other entrances and exits in the second area 2 of the collection application interface; the other entrances and exits are the remaining entrances and exits among the N entrances and exits except the i-th entrance and exit; i is a positive integer less than or equal to N.

[0084] As an example, see Appendix Figure 4 , the subway station has a total of three entrances and exits, namely A, B, C, and D. Select entrance A in the first area 1 of the collection application interface, and start the operation of making the subway passage by selecting "Make Subway Passage". According to on-site collection, it is determined that among B and C, entrance A can only reach B. Then, set entrance B to the selected state in the second area 2, and then complete the production task.

[0085] Step 306: In response to the selection operation for the identifier of other entrances and exits, obtain the connectivity relationship between the i-th entrance and exit and other entrances and exits according to the selection operation.

[0086] It should be noted that in some embodiments, when there is a connectivity relationship between the i-th entrance and exit and the j-th entrance and exit, in response to the selection instruction for the identifier of the j-th entrance and exit in the first area 1 and the operation information for making the subway passage event, set the identifier of the i-th entrance and exit displayed in the second area 2 of the collection application interface to the default selected state; j is a positive integer less than or equal to N, and the value of j is different from that of i.

[0087] As an example, such as Figure 5As shown, there are three entrances and exits, namely A, B, C, and D, in the subway station. At the first area 1 of the acquisition application interface, select entrance A, and start the operation of formulating the subway passage by selecting "formulate subway passage". According to on-site acquisition, it is determined that among B, C, and D, entrance A can only reach B. Then, change entrance B to the selected state in the second area 2. Subsequently, select entrance B in the first area 1. At this time, entrance A in the second area 2 is in the default selected state. According to on-site acquisition, it is determined that entrance B does not lead to entrance A, so the selected state of entrance A is cancelled.

[0088] Step 307: Generate a passable road model of the subway station according to the plane structure diagram and the connection relationship between the N entrances and exits.

[0089] In the embodiments of the present application, step 307 can be implemented in any one of the embodiments of the present application. The embodiments of the present application do not limit this and will not elaborate further.

[0090] According to the method for generating a passable road model in the subway station of the present application, by determining according to the connection relationship between every two of the entrances and exits, the generation of the passable road model of the subway station is gradually completed, ensuring the accuracy of the connection relationship between the entrances and exits, and reducing the operation difficulty of road acquisition. There is no need to rely on large-scale acquisition equipment, and the acquisition personnel do not need to master complex professional knowledge. By connecting the passable road model with the downstream walking navigation program, users can understand the passing situation of the subway station's internal passages, enabling users to make full use of the subway station's internal passages during walking, achieving the purpose of saving paths, and changing the original journey that requires crossing the road to walking through the subway station's internal passages, increasing the safety of passing.

[0091] To be able to generate a passable road model of the subway station, optionally, as Figure 6 shown, the method for generating the passable road model in the subway station may include:

[0092] Step 601: Obtain the subway station identifier of the current location of the electronic device.

[0093] In the embodiments of the present application, step 601 can be implemented in any one of the embodiments of the present application. The embodiments of the present application do not limit this and will not elaborate further.

[0094] Step 602: Obtain the plane structure diagram of the subway station according to the subway station identifier.

[0095] In the embodiments of the present application, step 602 can be implemented in any one of the embodiments of the present application. The embodiments of the present application do not limit this and will not elaborate further.

[0096] Step 603: Obtain the connectivity relationship between N entrances and exits in the subway station according to the operation information for making subway passage events on the collected application interface; where the collection application is installed on the electronic device; N is a positive integer.

[0097] In the embodiments of the present application, step 603 can be implemented in any one of the various embodiments of the present application. The embodiments of the present application do not make any limitations in this regard and will not be elaborated further.

[0098] Step 604: Determine the line segment type representing the connectivity relationship between two entrances and exits according to the connectivity relationship between every two of the N entrances and exits.

[0099] As an implementation method, refer to the appendix Figure 7 , when there are entrance A and entrance B, when entrance A can reach entrance B, but entrance B cannot reach entrance A, then a one-way arrow points from entrance A to entrance B; if entrance B can reach entrance A, but entrance A cannot reach entrance B, then a one-way arrow points from entrance B to entrance A; if entrance A can reach entrance B and entrance B can also reach entrance A, then entrance A and entrance B are connected by a line segment. If entrance A cannot reach entrance B and entrance B cannot reach entrance A either, then there is no connection between entrance A and entrance B. It should be noted that the one-way arrow and the line segment are only used as an example and do not constitute a limitation to the protection scope of the present application.

[0100] As another implementation method, when there are entrance A and entrance B, when entrance A can reach entrance B, but entrance B cannot reach entrance A, then entrance A and entrance B are connected by a yellow line segment, and the yellow line segment contains an arrow pointing from entrance A to entrance B; if entrance B can reach entrance A, but entrance A cannot reach entrance B, then entrance B and entrance A are connected by a yellow line segment, and the yellow line segment contains an arrow pointing from entrance B to entrance A; if entrance A can reach entrance B and entrance B can also reach entrance A, then entrance A and entrance B are connected by a green line segment. If entrance A cannot reach entrance B and entrance B cannot reach entrance A either, then there is no connection between entrance A and entrance B. It should be noted that the yellow line segment and the green line segment are only used as an example and do not constitute a limitation to the protection scope of the present application.

[0101] Step 605: Draw the line segments between every two entrances and exits in the planar structure diagram according to the line segment type representing the connectivity relationship between every two entrances and exits, to obtain the passable road model of the subway station.

[0102] According to the method for generating a passable road model in a subway station of the present application, by determining the connection relationships between various entrances and exits and generating different line types, users can quickly obtain the connection relationships between various entrances and exits through the line types, simply and effectively completing the display operation of the connection relationships between the entrances and exits, which is convenient for users to understand.

[0103] To further increase the convenience of using the acquisition application. Optionally, as Figure 8 shown, the method for generating a passable road model in a subway station may include:

[0104] Step 801, obtain the subway station identifier of the current location of the electronic device.

[0107] In the embodiments of the present application, step 802 can be implemented in any one of the embodiments of the present application. The embodiments of the present application do not make any limitations in this regard and will not be elaborated further.

[0108] Step 803, obtain the connectivity relationship between N entrances and exits in the subway station according to the operation information of making subway passage events on the interface of the acquisition application; wherein, the acquisition application is installed on the electronic device; N is a positive integer.

[0112] Step 805, display the passable road model in the third area of the interface of the acquisition application.

[0113] As an implementation, in response to a trigger operation on a shooting event on the acquisition application interface, an image of the entrance and exit of a subway station is acquired; a correspondence relationship between the captured image and the entrance and exit of the subway station is established, and the captured image is stored based on the correspondence relationship; in response to an operation on a target entrance and exit identifier displayed on the passable road model in the third area, the captured image of the target entrance and exit is acquired according to the correspondence relationship; the captured image of the target entrance and exit is displayed.

[0114] According to the method for generating a passable road model in a subway station of the present application, by displaying the generated passable road model in the third area, it is ensured that users can clearly and accurately obtain the position information of the passable road. By establishing a correspondence relationship between the captured image and the entrance and exit of the subway station, the convenience of the acquisition application during use is further increased.

[0115] To implement the above embodiments, the present application also proposes a device for generating a passable road model in a subway station.
