Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In order to more intuitively and clearly manage cameras and control video dynamics, the prior art creates a multi-source information fusion three-dimensional visualization platform by using a three-dimensional video fusion technology, and realizes real-time dynamic visualization monitoring of three-dimensional scenes. The multi-source information fusion three-dimensional visualization platform may include a number of functions: linkage of two three-dimensional maps, fusion and embedding of videos, switching of large and small scenes, linkage of small scenes and two-dimensional maps, simulation of weather and time, viewpoint roaming and the like. The entire three-dimensional visualization platform framework is provided by WPF (Windows Presentation Foundation), and the framework provides osgwindows and unitywindows for loading Unity windows and OSG (OpenSceneGraph application program interface) windows. Thus, the implementation of the above functions depends on communication and data transfer among the three components WPF, OSG and Unity. However, there is currently no complete set of communication means that can achieve data transfer between WPF and OSG and Unity.
In this regard, the embodiment of the invention provides a communication method. Fig. 1 is a flow chart of a communication method from a WPF platform to an OSG interface according to an embodiment of the present invention, as shown in fig. 1, where the method is applied to the WPF platform, and the method includes:
and 120, calling a viewpoint setting function, and transmitting data to be transmitted contained in the input parameters of the viewpoint setting function to an OSG interface for the OSG interface to set the viewpoint based on the data to be transmitted.
Specifically, the data to be transferred that needs to be transferred into the OSG interface is first determined. For example, the data to be transferred may be parameter information such as the name and longitude and latitude of the model being operated in the WPF platform. In order to transmit the data to be transferred to the OSG interface, the data communication between the two platforms can be implemented in a function call manner. In particular, considering that the purpose of the WPF platform to transmit data into the OSG is to set a viewpoint in the OSG generally, the WPF platform may take the data to be transferred as an incoming parameter of a viewpoint setting function provided by the OSG to the outside, and directly call the viewpoint setting function, so that the OSG interface performs viewpoint setting based on the incoming data to be transferred. When the WPF calls the viewpoint setting function, the data to be transferred is transferred into the viewpoint setting function in the manner of the input parameters, so that the OSG interface can acquire the data to be transferred in the input parameters when executing the viewpoint setting function, and the data transfer from the WPF platform to the OSG interface is realized.
According to the method provided by the embodiment of the invention, the data to be transferred is set as the input parameters of the viewpoint setting function provided by the OSG interface, the viewpoint setting function is called, and the data to be transferred contained in the input parameters of the viewpoint setting function is transmitted to the OSG interface, so that the data transfer from the WPF platform to the OSG interface is realized, and the communication efficiency is high and the operation is stable.
Based on the above embodiment, the method further includes:
based on the built-in Unity executable program, the data to be transferred is transmitted to the Unity platform in a message format through a socket.
Specifically, in the current communication method, in order to transfer data between the WPF platform and the Unity platform, it is generally implemented using a UnityWebPlayer plug-in. However, the UnityWebPlayer plugin is essentially a plugin for playing the Unity page stream on the webpage, which has the problem of slow loading, and reduces the communication efficiency between the WPF platform and the Unity platform. Therefore, in order to improve communication efficiency, the embodiment of the invention realizes data transfer between the WPF platform and the Unity platform by using a message communication mode.
Here, the executable program generated by the Unity may be embedded in the WPF program in advance, and the WPF platform serves as a server side, and the Unity platform itself serves as a client side. When data transmission is needed, the data to be transmitted is packaged into a message, and then the built-in Unity executable program can send the message packaged with the data to be transmitted to the Unity platform through a socket. The message format may be a UDP protocol message or a TCP protocol message, which is not specifically limited in the embodiment of the present invention.
According to the method provided by the embodiment of the invention, the data to be transmitted is packaged into the message, and the message is sent to the Unity through the socket, so that the communication efficiency between the WPF platform and the Unity platform is improved.
Based on any of the above embodiments, fig. 2 is a flow chart of a communication method from an OSG interface to a WPF platform according to an embodiment of the present invention, as shown in fig. 2, where the method is applied to the OSG interface, and the method includes:
Specifically, after the WPF platform invokes the viewpoint setting function provided by the OSG interface, the OSG interface processes data carried in the input parameters of the viewpoint setting function, and returns new data to be transferred, for example, whether a desired model is selected, relevant information of the model, and the like. It should be noted that, when the WPF platform invokes the viewpoint setting function, the incoming parameters include not only the transmitted data itself, but also function hosting provided by the WPF platform for processing the data returned by the OSG, that is, hosting of the interface update function. The WPF platform synchronously transmits the host of the interface updating function to the OSG interface in the mode of the input parameters, so that the OSG interface can transmit the data to be transmitted back to the WPF platform in the mode of function call by means of the interface updating function.
Therefore, after the mandate of the interface update function which is transmitted when the WPF platform calls the viewpoint setting function provided by the OSG interface is received, the data to be transmitted is used as the transmission parameter of the interface update function provided by the WPF platform, and the interface update function is called through the callback function so that the WPF platform can update the interface based on the transmission data. When the OSG calls the interface updating function through the callback function, the data to be transferred is transferred to the inside of the interface updating function in the mode of the input parameter, so that the OSG interface can acquire the data to be transferred in the input parameter when executing the interface updating function, and the data transfer from the OSG interface to the WPF platform is realized.
In addition, when the OSG interface calls the interface update function provided by the WPF through the callback function, the interface update function needs to change the interface of the front end. However, at this point the UI object at the front end is being occupied by the UI thread in the WPF platform, resulting in an inability to update the front end interface. For this, a Dispatcher object of the UI in the WPF platform may be used, and an invoke method of the Dispatcher object may be called, and the interface update function may be submitted to the method to execute, so as to implement the update of the front-end interface.
According to the method provided by the embodiment of the invention, the data to be transferred is set as the input parameters of the interface updating function input by the WPF platform, and the interface updating function is called by the callback function, so that the data to be transferred contained in the input parameters of the interface updating function is transferred to the WPF platform, the data transfer from the OSG interface to the WPF platform is realized, and the communication efficiency is high and the operation is stable.
Based on any of the foregoing embodiments, in step 230, based on the hosting of the interface update function, the interface update function is called by the callback function, which specifically includes:
converting the host of the interface updating function into a function pointer corresponding to the interface updating function;
and calling the interface updating function through the callback function based on the function pointer corresponding to the interface updating function.
Specifically, since the WPF platform is written in the c# language and the OSG interface is written in the c++, the OSG interface cannot directly make function calls according to the hosting of the interface update function. Therefore, the host of the interface update function needs to be converted into a form which can be understood by the OSG interface, that is, into a function pointer corresponding to the interface update function. For example, the hosting of the interface update function may be converted to an IntPtr type, which in turn is converted to a function pointer of the corresponding type. And then, calling the interface updating function through the callback function according to the function pointer corresponding to the interface updating function.
Before converting the host of the interface update function, a corresponding callback function and a function pointer corresponding to the callback function form may be declared in the OSG in advance. At the same time, it is also necessary to declare a host corresponding to the function pointer of the OSG in the WPF platform, and to give the interface update function provided by the WPF platform to the host for delivery to the corresponding function pointer in the OSG.
For example, a function pointer named MessageCallback may be first declared in the class of OSGH and a class variable_ mcb of this type may be declared in OSG and. Then, an interface update function CallBackFunc to be called is prepared in the WPF platform, and a message callback type of managed is created, and the initialization value of the managed is called a message callbackdelete. After the WPF platform calls a viewpoint setting function and transmits the managed MessageCallBackDelegate to an OSG interface, the OSG interface firstly converts the managed into an IntPtr type, then converts the IntPtr type into a function pointer corresponding to the MessageCallBack and consistent with the MessageCallBack, assigns the function pointer to a variable_ mcb in the OSGhand ler class, and then the OSG interface updates the function CallBackFunc through a callback function call interface. In this way, after the callback function is used in the OSG platform, the interface update function provided by the WPF platform is directly triggered, so that data transfer from the OSG interface to the WPF platform is realized. In addition, since the C# has a garbage recycling mechanism, in order to prevent the managed messagecallbackDelegate from being recycled in advance, a keepAlive method can be called to ensure that the managed corresponding interface update function survives.
Based on any one of the foregoing embodiments, a further embodiment of the present invention provides a communication method, where the method is applied to a Unity platform, and the method includes:
based on the socket embedded in the Unity program script, the data to be transferred are transmitted to the WPF platform in a message format.
Specifically, socket content can be embedded in a Unity program script of a Unity platform in advance, the Unity platform is taken as a client, and a Unity executable program embedded in the WPF platform is taken as a server. When data transmission is needed, the data to be transmitted is packaged into a message, and then the message packaged with the data to be transmitted is sent to the WPF platform through a socket embedded in a Unity program script. The message format may be a UDP protocol message or a TCP protocol message, which is not specifically limited in the embodiment of the present invention.
According to the method provided by the embodiment of the invention, the data to be transmitted is packaged into the message, and the message is sent to the WPF platform through the socket, so that the communication efficiency between the WPF platform and the Unity platform is improved.
Based on any of the foregoing embodiments, another embodiment of the present invention provides a communication method, including:
transmitting data to be transmitted to the WPF platform in a message format based on a socket embedded in a Unity program script of the Unity platform;
after the WPF platform sets the received data to be transferred as the input parameters of the viewpoint setting function provided by the OSG interface, the viewpoint setting function is called, and the data to be transferred contained in the input parameters of the viewpoint setting function is transmitted to the OSG interface.
Specifically, the Unity platform and the OSG interface may communicate indirectly through WPF as a medium, i.e. the Unity platform first transmits the data to be transferred to the WPF platform, and the WPF platform transmits the data to be transferred to the OSG interface. Fig. 3 is a flow chart of a communication method between a Unity platform and an OSG interface provided by the embodiment of the present invention, as shown in fig. 3, the Unity platform uses a socket embedded in a Unity program script to transmit data to be transmitted to a WPF platform through a message, and a specific transmission manner may be the communication method from the Unity platform to the WPF platform provided by any one of the embodiments, which is not described herein. After the WPF receives the data to be transferred, the data to be transferred is set as an input parameter of a viewpoint setting function provided by the OSG interface, the viewpoint setting function is called, the data to be transferred included in the input parameter of the viewpoint setting function is transferred to the OSG interface, and a specific transfer mode may be a communication method from the WPF platform to the OSG interface provided by any embodiment, which is not described herein again.
According to the method provided by the embodiment of the invention, the WPF is used as a medium, the Unity platform transmits the data to be transmitted to the WPF platform, and the WPF platform transmits the data to be transmitted to the OSG interface, so that the communication between the Unity platform and the OSG interface can be realized.

the OSG interface calls the interface updating function through a callback function based on the hosting of the interface updating function, and transmits data to be transmitted contained in the input parameters of the interface updating function to the WPF platform;
the WPF platform transmits data to be transmitted to the Unity platform in a message format through a socket based on a built-in Unity executable program.
Specifically, when the OSG interface needs to transfer data to the Unity platform, the WPF platform may still be used as a medium to implement indirect communication between the OSG interface and the Unity platform. As shown in fig. 3, after the OSG interface receives the hosting of the interface update function that is input when the WPF platform invokes the viewpoint setting function, the data to be transferred is set as the input parameter of the interface update function, and based on the hosting of the interface update function, the interface update function is invoked by the callback function, so that the data to be transferred included in the input parameter of the interface update function is transferred to the WPF platform, and a specific transfer manner may be the communication method from the OSG interface to the WPF platform provided in any of the foregoing embodiments, which is not described herein again.
