[0034] With the rapid development of information technology, users' demands for tourism quality are constantly increasing. Currently, most tour guide and attraction information in scenic areas requires users to actively search for it.

[0070] Figure 4 The trajectory video generation method provided by the embodiments of the present application is applied to a server and can also be applied to a generation device, which can be the generation device 12 in Figure 1 , or a device such as a chip in the generation device 12. The embodiments of the present application take the generation device 12 as an example for illustration, as shown in Figure 4 , the method includes the following S401-S404:

[0071] S401, the generation device receives first indication information sent by a network device.

[0072] The first indication information is used to indicate that a target terminal appears in a preset electronic fence, and the electronic fence includes multiple nodes.

[0073] The target terminal can be any terminal with a mobile communication function. The electronic fence can be an area covering a specific scene. For example, the specific scene can be a scenic spot, and the multiple nodes can be multiple scenic spots in the scenic spot.

[0074] For another example, the specific scene can be a school, and the multiple nodes can be multiple buildings in the school, without limitation.

[0075] As a possible implementation manner, when the target terminal appears in the preset electronic fence, the target terminal can send a radio resource control (RRC) connection message to the network device. The network device determines that the target terminal appears in the preset electronic fence when receiving the RRC connection message sent by the target terminal, and sends first indication information to the generation device. Correspondingly, the generation device receives the first indication information sent by the network device.

[0076] As a further possible implementation, the target terminal can send the positioning information to the network device. The network device, upon receiving the positioning information sent by the target terminal, can match the positioning information of the target terminal with the location range of the electronic fence. If the positioning information of the target terminal is located in the location range of the electronic fence, the network device sends the first indication information to the generating apparatus. Correspondingly, the generating apparatus receives the first indication information sent by the network device.

[0077] It should be noted that the above possible implementations are only exemplary and not limited.

[0078] S402, the generating apparatus listens to the location information of the target terminal.

[0079] The location information can be longitude and latitude information, coordinate information, etc.

[0080] As a possible implementation, the generating apparatus can send a positioning request message to the network device. The network device, upon receiving the positioning request message sent by the generating apparatus, can determine the location information of the target terminal based on the base station positioning technology, and send a positioning reply message to the generating apparatus. The generating apparatus can listen to the location information of the target terminal based on receiving the positioning reply message sent by the network device.

[0081] It should be noted that the specific process of listening to the location information of the target terminal in this step can refer to the description of the subsequent steps, which will not be repeated here.

[0082] In some embodiments, the generating apparatus can also directly determine the location information of the target terminal according to the GPS of the target terminal. For example, the generating apparatus can send a positioning request message to the target terminal. The target terminal, upon receiving the positioning request message sent by the generating apparatus, can determine the location information of the target terminal based on the GPS, and send a positioning reply message to the generating apparatus. The generating apparatus can listen to the location information of the target terminal based on receiving the positioning reply message sent by the network device.

[0083] It should be noted that the frequency of the generating apparatus listening to the location information of the target terminal can be set as needed. For example, it can be 1 time per second, or 1 time per 0.5 seconds, etc.

[0084] S403, the generating apparatus acquires the target route map and the target route information in the electronic fence.

[0085] The target route map includes a plurality of passing nodes and paths between the passing nodes, and the target route information includes the location information of each passing node, the location information of the paths between the passing nodes, and one or more real scene pictures.

[0086] As a possible implementation manner, the generating apparatus can be in communication connection with a third-party database, and the third-party database pre-stores the target route map and the target route information in the electronic fence. The generating apparatus can send a first subscription message to the third-party database, and the first subscription message is used to request the target route map and the target route information in the electronic fence. After receiving the first subscription message sent by the generating apparatus, the third-party database can send a first reply message to the generating apparatus, and the first reply message includes the target route map and the target route information in the electronic fence. The generating apparatus can acquire the target route map and the target route information in the electronic fence based on the first reply message.

[0087] It should be noted that the one or more real scene pictures can be attached with corresponding picture information, and the picture information can be position information of the picture.

[0088] S404, the generating apparatus matches the position information of the target terminal with the target route map according to the target route information, to generate the track video.

[0089] The track video includes a plurality of image frames, and each image frame includes position information identification of the target terminal in the target route map, a timestamp, and / or one or more real scene pictures at the position information identification.

[0090] As a possible implementation manner, the generating apparatus can determine the position of the target terminal in the target route map according to the target route information, and label the position of the target terminal in the target route map to generate a plurality of image frames. Further, the generating apparatus arranges the plurality of image frames in the order of the timestamps of the image frames on the target route map, to generate the track video.

[0091] It should be noted that the form of the label can be adding a point label to the geographical position where the picture is taken, which is not limited here. The one or more real scene pictures can be pre-stored in the database or uploaded after being taken by the target terminal.

[0092] Based on the technical solution provided in the present application, after the target terminal appears in the preset electronic fence, the generating apparatus can listen to the position information of the target terminal, acquire the target route map and the target route information in the electronic fence, and then match the position information of the target terminal with the target route map according to the target route information, to generate the track video, without the need for the user to actively participate, simplifying the user operation and improving the user experience.

[0093] As shown in a possible embodiment, Figure 5 To generate the electronic fence, the issuing method of the present application can further include the following S501-S502.

[0094] S501, the generating device acquires boundary information of the target area.

[0095] The boundary information can include position information of the boundary of the target area, such as longitude and latitude information, or coordinate information of the boundary position.

[0096] As a possible implementation, the generating device can be provided with an input device, such as a keyboard. The user can input the position information of the boundary of the target area through the input device, and then the generating device can acquire the boundary information of the target area according to the input operation of the user.

[0097] S502, the generating device generates an electronic fence according to the boundary information.

[0098] The electronic fence refers to a virtual fence for dividing the target area into a target area and a non-target area.

[0099] As a possible implementation, the generating device can set a plurality of boundary nodes on the boundary of the target area, connect the boundary nodes in a setting manner, and then obtain the electronic fence of the target area. The shape of the boundary of the target area can also be approximated to obtain the electronic fence of the target area. Of course, other algorithms can also be used to obtain the electronic fence of the target area. The electronic fence of the target area can also be generated by a machine learning algorithm and a geographic information system (GIS).

[0100] It should be noted that the possible implementation of this step is only exemplary and not limited.

[0101] In this way, the generating device can set the electronic fence to demarcate the target area, and then the target terminal can be found in the target area in time.

[0102] As a possible embodiment, as shown in Figure 6 To determine the position information of the target terminal, S402 in the determination method of the present application can further include S601-S602.

[0103] S601, the generating device sends a positioning request message to the network device, so that the network device analyzes the position information of the target terminal according to the measurement report of the target terminal.

[0104] The measurement report can include various positioning information, such as signal strength, uplink and downlink delay, and angle of arrival.

[0105] As a possible implementation, the generating device is configured with one or more positioning algorithms, and different positioning algorithms require different positioning information. The generating device can obtain the position information of the target terminal according to the positioning algorithm and the corresponding positioning information in the measurement report.

[0106] It should be noted that the target terminal can send the measurement report at a preset frequency. The preset frequency can be set as needed. For example, the preset frequency can be 1 time per second, etc., without limitation. The higher the preset frequency, the higher the accuracy of positioning the target terminal.

[0107] It should be noted that the transmission data form of the measurement report can be a data message, etc.

[0108] In some embodiments, in order to ensure the security of the measurement report, the target terminal can encrypt the measurement report.

[0109] S602, the generating device receives the positioning reply message sent by the network device.

[0110] The positioning reply message includes the position information of the target terminal.

[0111] As a possible implementation, the network device can encrypt the positioning reply message and send the encrypted positioning reply message to the generating device. Correspondingly, the generating device receives the encrypted positioning reply message sent by the network device, and decrypts the encrypted positioning reply message to obtain the positioning reply message.

[0112] It should be noted that the encryption method can be set as needed, without limitation.

[0113] In this way, the generating device can monitor the position information of the target terminal in real time after the target terminal enters the target area, so as to issue the node introduction information and path planning information corresponding to the position according to the position information of the target terminal. And it does not need additional positioning technology (such as GPS positioning technology) or download other applications, and the power consumption of the target terminal is small, which improves the user experience.

[0114] As a possible embodiment, as shown in Figure 7 The determination method of the present application can further include the following S701.
