Like components are denoted by the same reference numerals in the drawings. It should be understood by those skilled in the art that the specific description below is illustrative rather than limiting, and should not limit the scope of protection of the present application.

[0055] In order to solve the problems of low management efficiency and high management cost in the related art, the inventors have found that the reasons for the above-mentioned problems of park management are that the following problems are not solved: modeling of the park, collection and updating of real-time changes of the park, and unification of multiple platforms of user terminals.

[0056] According to the above-mentioned problems, an embodiment of the present application provides a park management method applied to a user terminal, including: Figure 1

[0057] In response to a first operation of a user, a first read data request is sent to a server, so that the server loads a pre-set park three-dimensional model according to the first read data request, and generates a preset perspective media stream by rendering according to received sensor data, and returns a pull stream address of the media stream;

[0058] In response to a second operation of a user, the media stream is pulled from the server according to the pull stream address and played, and the user terminal is applied to each application system.

[0059] In the embodiment, the collection of real-time changes of the park is solved by the sensor data caused by real-time changes of the park provided by the sensor set arranged at each position of the park, the modeling of the park is realized by the park three-dimensional model loaded by the server, the media stream is formed by rendering the park three-dimensional model and real-time sensor data by three-dimensional rendering technology, the online three-dimensional virtual park is realized by streaming media technology, and the management and control of the online three-dimensional virtual park is realized by the user terminal pulling and playing the media stream, so that the user can view the current state of the park and manage the park equipment without going out, the user terminal can be applied to multiple application platforms by cross-platform technology, thereby solving the unification of multiple platforms, effectively improving the park management efficiency, reducing the user terminal cost of park management, and having a wide application prospect.

[0060] In a specific embodiment, as shown in Figure 2 ​As shown, the park management system provided by the present application comprises a user terminal, a server, and a sensor set comprising a plurality of sensors. The user terminal is a terminal used by a user, which can be a mobile terminal such as a smart phone and a smart tablet, a web terminal such as a webpage, a PC terminal such as a computer device, or a virtual reality terminal such as a VR glasses. The user terminal supports a plurality of application systems, such as application systems based on the Flutter language supporting Linux, Windows, Android, IOS, etc. Specifically, the user terminal comprises a cross-platform player, which comprises a packaged first player and a second player. The first player is a dart_vlc player supporting IOS, Linux, MacOS, and Windows platforms. The second player is a fijkplayer player supporting Android and IOS platforms. The cross-platform player realizes business logic adaptation by standardizing the interfaces of the two player libraries, thereby solving the problem of multi-platform unification and effectively reducing the cost of the user terminal of the park management. The server is a server providing services, which can be a server arranged in the park or a remote server or a cloud server. The server comprises a management sub-terminal, a three-dimensional rendering sub-terminal, and a streaming media sub-terminal deployed on the same or different servers. The management sub-terminal is connected to the user terminal, the sensor set, and the three-dimensional rendering sub-terminal, and is used for forwarding information and user management. The three-dimensional rendering sub-terminal comprises a stored three-dimensional model of the park and an application for realizing three-dimensional rendering. The streaming media sub-terminal comprises a cached media stream and an application for managing streaming and pulling.

[0061] As shown in the specific example. Figure 3

[0062] In the first step, the user terminal 200 sends a first read data request to the management sub-terminal of the server.

[0063] In this embodiment, the user terminal is a smart tablet. The user first logs in to the user terminal. Specifically, the user inputs a username and a password, and the user terminal transmits the username and the password to the management sub-terminal of the server. The management sub-terminal comprises a user management function for checking the username and the password received by the user terminal. After verification, the management sub-terminal returns a verification result to the smart tablet. If the verification result is correct, the user logs in successfully. Otherwise, the user fails to log in.

[0064] ​In response to the successful login of the user, the smart tablet starts a cross-platform player, which identifies the application system of the smart tablet, such as loading and starting the fijkplayer player through a packaged standard interface if the smart tablet is an Android system, or loading and starting the dart_vlc player through a packaged standard interface if the smart tablet is an IOS system.

[0065] Meanwhile, the cross-platform player sends a first read data request to the management sub-end, and the first read data request includes the window size of the application system.

[0066] In the second step, the management sub-end 1001 of the service end 100 receives the first read data request and forwards it to the three-dimensional rendering sub-end 1002.

[0067] In the embodiment, the management sub-end forwards the first read data request to the three-dimensional rendering sub-end, and at the same time, the management sub-end receives the sensor data sent by the sensor set 300 and transmits the sensor data to the three-dimensional rendering sub-end.

[0068] In the third step, the three-dimensional rendering sub-end 1002 generates a media stream.

[0069] In the embodiment, the three-dimensional rendering sub-end loads a pre-set park three-dimensional model based on the UE4 Unreal Engine, forms a camera window according to the sensor data and the window size of the smart tablet in the first read data request, and generates a media stream of a preset perspective through rendering. Specifically, when the three-dimensional rendering sub-end receives the first read data request, the UE4 forms a camera window in an initial position defined in the three-dimensional model world coordinate system according to the window size of the smart tablet, and according to a preset perspective, such as an initial perspective, and then collects camera window image and audio data through an FFmpeg application plug-in, wherein the video sampling frame rate is 60 fps and the audio sampling rate is 48 kHz, and the audio and video data are packaged as FLV data stream for media stream transmission.

[0070] In the fourth step, the three-dimensional rendering sub-end 1002 requests a push stream address from the streaming media sub-end 1003.

[0071] In the fifth step, the three-dimensional rendering sub-end 1002 pushes the media stream to the streaming media sub-end 1003.

[0072] In the sixth step, the three-dimensional rendering sub-end 1002 receives a pull stream address sent by the streaming media sub-end 1003.

[0073] In the embodiment, the three-dimensional rendering sub-end requests a push stream address from the streaming media sub-end and obtains the push stream address returned by the streaming media sub-end, and uploads the FLV data stream to the streaming media sub-end according to the RTMP protocol. The streaming media sub-end caches the media stream, and returns the pull stream address of the media stream to the three-dimensional rendering sub-end.

[0074] Step 7, the three-dimensional rendering sub-client 1002 sends the pull stream address to the management sub-client 1001.

[0075] Step 8, the management sub-client 1001 sends the pull stream address to the user client 200.

[0076] In this embodiment, the three-dimensional rendering sub-client forwards the pull stream address to the user client through the management sub-client, so that the user client pulls the media stream from the stream media sub-client according to the pull stream address.

[0077] Step 9, the user client 200 pulls the media stream from the stream media sub-client according to the pull stream address.

[0078] Step 10, the user client 200 plays the media stream

[0079] In this embodiment, the cross-platform player acquires the media stream from the stream media sub-client through the pull stream address in response to the user's operation, parses and renders the media stream to generate playing data, and plays the playing data according to the started fijkplayer or dart_vlc player. Specifically, for example, if the smart tablet is an Android system, the fijkplayer is started to play the playing data parsed and rendered by the cross-platform player, and if the smart tablet is an IOS system, the dart_vlc player is started to play the playing data parsed and rendered by the cross-platform player. As shown in FIG. 8, the media stream is presented by the smart tablet, specifically, the middle is a three-dimensional virtual park, the left side is a display option, and the right side is a chart and panel display. The user can control the park in real time through the three-dimensional virtual park online through the smart tablet, realize viewing the current state of the park and managing the devices of the park without going out, and effectively improve the park management efficiency. Figure 4

[0080] This embodiment realizes the rendering of the three-dimensional model and generates the dynamically changing media stream through the three-dimensional rendering technology, and realizes the pushing, caching and pulling of the media stream through the stream media technology, thereby realizing the dynamic monitoring of the park.

[0081] ​In consideration of different users' attention to different locations in the park, on the basis of playing the media stream at the user end to show the park dynamics, in an optional embodiment, the park management method further comprises: the cross-platform player responds to a third operation of a user and sends a second read data request to the server, the second read data request comprises update information generated by the displacement of the third operation of the user relative to the cross-platform player, the update information comprises at least one of an update location, an update perspective, an update offset, an update direction and an update multiple, so that the three-dimensional rendering sub-end renders according to the update information and generates a first update media stream and pushes the first update media stream to the streaming media sub-end, and the streaming media sub-end caches the first update media stream and returns a first update pull stream address of the first update media stream; the cross-platform player pulls the first update media stream from the server according to the first update pull stream address and plays.

[0082] In the embodiment, based on the three-dimensional virtual park presented by the cross-platform player at the user end, the user can operate the three-dimensional virtual park through gestures or connected external devices such as a mouse in the cross-platform player interface. The gesture operation of the embodiment includes double-finger zooming, three-finger moving, single-finger long-press rotating, single-click selecting a target, double-click fixing zooming and the like. Specifically, the user can update the viewing position, viewing content and viewing perspective through gesture operation on the smart tablet.

[0083] In a specific example, for example, the user adopts a single-finger long-press rotating gesture, the relative length of the user's finger moving in the x direction of the cross-platform player is 1%, and the park model is rotated by 3.6 degrees in the x direction; for example, the user adopts a two-finger zooming gesture, the relative length of the user's finger moving in the x direction of the player is 1%, and the park model is enlarged by 1.03 times in the x direction; for example, the user adopts a three-finger moving gesture, the relative length of the user's finger moving in the x direction of the player is 1%, and the park model is moved by 1% in the x direction; for example, the user adopts a single-finger clicking gesture, the offset of the user's finger in the x, y, and z axes of the three-dimensional virtual park relative to the initial position of the three-dimensional virtual park, that is, according to the position of the single-finger clicking gesture on the player interface, the offset is superimposed to find the clicking position on the model; that is, through the gesture operation of the user on the cross-platform player, an update operation is started, and the user's gesture update is mapped to the three-dimensional rendering sub-end. Specifically, after the user changes the viewing position of the three-dimensional virtual park by gesture operation, the cross-platform player generates update information according to the displacement of the user's gesture operation relative to the cross-platform player, and sends a second read data request to the management sub-end of the service end, which is forwarded to the three-dimensional rendering sub-end by the management sub-end. The three-dimensional rendering sub-end re-renders according to the second read data request and the sensor set sensing data and generates an updated media stream, which is pushed to the streaming media sub-end through the streaming address, and the obtained pull streaming address is transmitted to the smart tablet, so that the cross-platform player running on the smart tablet pulls the updated media stream and plays, thereby realizing the viewing of different positions and different perspectives of the three-dimensional virtual park in response to the user's operation, and enabling the user to view the current state of the park and manage the park equipment without leaving home, effectively improving the park management efficiency.

[0084] It is worth noting that the user can also control the devices in the park through the operation on the cross-platform player, for example, controlling the sensors in the park, such as turning on or off a certain camera, or changing the camera direction of a certain camera to view different positions, etc. When the user controls the devices in the park through the operation, the control instruction is transmitted to the specified sensor in the sensor set through the management sub-end in response to the user's operation, thereby realizing the control of the sensor and synchronizing the changes to the three-dimensional virtual park in real time, so that the user can experience online park management. Those skilled in the art should understand that when other devices in the park are accessed through the management sub-end, the operation of the above-mentioned devices can be realized, which is within the protection scope of the present application, and will not be described here.

[0085] In view of the real-time sensing of changes in the park by the sensors, in an optional embodiment, the park management method further comprises: the cross-platform player sending a second read data request to the server in response to the updated sensor data forwarded by the server, so that the three-dimensional rendering sub-end renders according to the updated sensor data and generates a second updated media stream, and returns a second updated pull stream address of the second updated media stream; and the cross-platform player pulls the second updated media stream from the server according to the second updated pull stream address and plays it.

[0086] In this embodiment, when the user monitors the three-dimensional virtual park on the smart tablet, the cross-platform player initiates the update of the three-dimensional virtual park based on the real-time changes of the sensor data in response to the update of the sensor data, for example, the sensor senses updated data and reports to the cross-platform player of the user terminal through the management sub-end. Specifically, it includes: sending a second read data request to the management sub-end, forwarding it to the three-dimensional rendering sub-end through the management sub-end, and re-rendering according to the updated sensor data to generate a new media stream, and then pushing the new media stream to the streaming media sub-end through the push operation, so that the cross-platform player pulls the new media stream according to the pull stream address and presents it, thereby realizing real-time update of the three-dimensional virtual park, real-time mapping of the actual park, effectively realizing online park management, and improving the efficiency of park management.

[0087] It is worth noting that the management sub-end receives the updated sensor data of the sensor in real time, and the management sub-end transmits the sensor data to the three-dimensional rendering sub-end in real time. Those skilled in the art should understand that the three-dimensional rendering sub-end also initiates rendering and generates a new media stream according to the received sensor data; the present application does not make specific limitations on initiating re-rendering, and those skilled in the art should select appropriate update strategies according to actual application requirements to realize real-time update of the three-dimensional virtual park according to the actual changes of the park as the design criterion, which will not be described here.

[0088] So far, the intelligent monitoring of the park through the three-dimensional virtual park has been realized.

[0089] In this embodiment, the sensor set provides real-time sensor data caused by the change factors of the park, the server renders the media stream of the preset perspective according to the three-dimensional model of the park and the received sensor data, thereby realizing the online three-dimensional virtual park, and the user terminal pulls and plays the media stream to realize the management and control of the online three-dimensional virtual park, so that the user can view the current state of the park and manage the park equipment without going out, thereby improving the efficiency of park management; at the same time, through the cross-platform technology, it can be applied to various application systems, effectively reducing the cost of the user terminal of the park management, and has a wide application prospect.
