Fig. 2 shows a distributed panorama fusion system according to an embodiment of the present application, which includes a cloud server 201, a router 202, a fusion terminal 203, and a projector 204.
The cloud server 201 is used for sending a video file and a display instruction to the router 202, the display instruction is used for determining the position of the fusion terminal 203 and the corresponding relation between the position and the video file, and the cloud server can send different video files according to the requirements of different festivals of solar terms and holidays for setting off festivals. The display instruction can set the positions of different terminals, the terminal position refers to a corresponding picture position of a full picture of a video file displayed by the terminal, for example, a convergence terminal with an ip address of 192.168.1.10 is set to display 10% of picture content with the upper left corner of the full picture as the center, as shown in a projection 1 in fig. 3, so that the convergence terminal obtains a corresponding display file after analyzing according to the video file and the display instruction, and sends the display file to a correspondingly connected projector for display projection.
The router 202 is configured to receive the video file and the display instruction sent by the cloud server 201, and send the video file and the display instruction to the convergence terminal.
The convergence terminal 203 is configured to receive the video file and the display instruction sent by the router 201, parse the video file and the display instruction, determine the position of the convergence terminal 203, determine the display file according to the position, and send the display file to the projector 204 connected to the convergence terminal. For example, when a terminal with an ip address of 192.168.1.10 in the convergence terminal parsing display instruction with an ip address of 192.168.1.10 displays 10% of picture content with the top left corner of the full-width picture as the center, the convergence terminal parses to obtain a video file corresponding to the 10% picture, performs video fusion processing on the corresponding video file to determine a display file, and sends the display file to a projector connected with the display file.
The projector 204 is configured to receive a display file sent by the convergence terminal 203 connected to the projector 204 and perform projection display, where the number of the convergence terminal 203 corresponds to that of the projector 204, and the number is at least one. The projector is connected with the fusion terminal through an HDMI.
The convergence terminal receives the video file and the display instruction sent by the router through a UDP protocol in a wired or wireless mode. Therefore, after the fusion terminal communicates in a wireless mode, the wiring construction difficulty of the panoramic fusion system can be greatly reduced.
The fusion terminal receives and analyzes the video file and the display instruction by adopting an android operating system, determines the display file, and sends the display file to a projector connected with the display file. Thus, the cost of the convergence terminal is greatly reduced. After the cost of the fusion terminal is reduced, the cost of the whole panoramic fusion system can be reduced by 70 percent compared with the cost of the conventional panoramic fusion system.
And the fusion terminal receives the video file and then analyzes the video file through chip hard decoding. In this way, the hard decoding method of the convergence terminal greatly shortens the video analysis time compared with the conventional soft decoding method.
And the fusion terminal analyzes the video file and then performs panoramic fusion through OPENGL. Specifically, according to the determined terminal position, the fusion terminal performs gamma correction and white balance determination on data at the edge of a display picture in a video file through OPENGL to determine a display file, so as to realize panoramic fusion. For example, in the third embodiment, the fusion terminal corresponding to the projector 1 performs gamma correction and white balance on the region connected to the display content of the projector 2, sharpens the connected display region, and implements frame fusion and further panoramic fusion.
The video files received by all the fusion terminals in the distributed panoramic fusion system are the same. Obviously, the video files received by all the fusion terminals are the same, and different fusion terminals display different positions of the same video file, so that video synchronization can be realized, and further panoramic fusion can be realized.
The convergence terminal also acquires the software version through the router to realize software updating.
Wherein, the fusion terminal and the projector connected with the fusion terminal can be arranged nearby. Therefore, the wiring construction difficulty of the whole panoramic fusion system can be reduced.
The router is further used for receiving a control instruction sent by the mobile phone and sending the control instruction to the cloud server, and the control instruction is used for determining the video file and the display instruction, so that the content of the video file which is sent to the fusion terminal by the cloud server and displayed on the projector can be determined through the mobile phone. And remote control is realized.
The foregoing description has been directed to specific embodiments of this disclosure. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims may be performed in a different order than in the embodiments and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing may also be possible or may be advantageous.
In summary, according to the exemplary embodiment, the fusion terminal in the distributed panorama fusion system determines the position and the content of the display file of the fusion terminal by receiving and analyzing the video file and the display instruction sent by the cloud server, so as to implement the synchronous panorama fusion projection display of the same video file. The panoramic fusion system adopts a distributed architecture, so that the increase or reduction of equipment is facilitated, the close arrangement of the fusion terminal and the projector reduces the wiring construction difficulty, and the remote setting of video files and display instructions can be realized through a mobile phone.
