Description

Technical Field

[0001] The present invention relates to the field of computer technology applications, and in particular to a video processing system and method based on a cloud-based intelligent fusion device. Background Art

[0002] The fusion projection equipment group usually consists of multiple fusion projection equipment. Different fusion projection equipment projects a part of the video respectively, and each part constitutes a complete video content. Therefore, the original video will involve operations such as compression, cutting, and fusion processing. In addition to being related to the arrangement of the fusion projection equipment, the video cutting parameters are also affected by the on-site environment, such as projection background deformation, ambient brightness, and the superposition of the content projected by different fusion projection equipment.

[0003] In the advertising machine mode, it is usually assumed that all fusion projection devices receive the same content. However, in the fusion projection environment, because the size, distance, size and deformation of the projection background at different sites are different, even if the arrangement is the same, the projection parameters at different sites are different, so the advertising machine mode cannot handle the differences in content slices caused by different parameters of different fusion projection devices.

[0004] Because the projection fusion parameters of different sites are different, in the existing solutions, video processing, fusion, and processing usually occur on the user side. When cutting, technicians need to connect the fusion projection equipment on site, read the relevant parameters of the fusion projection equipment (such as the number of devices, arrangement, correction, fusion parameters, etc.), and then cut and upload the video.

[0044] In summary, if Figure 2 As shown, Figure 2 is a schematic diagram of another video processing system based on a cloud-based intelligent fusion device according to Embodiment 1 of the present invention. In the video processing system based on a cloud-based intelligent fusion device provided in the embodiment of the present application, the configuration, debugging, video processing and cutting of the fusion device group are all performed through the cloud ( Figure 2 This is achieved by using the cloud server in the .

[0045] The video processing system based on the cloud-based intelligent fusion device provided in the embodiment of the present application is divided into two parts during the specific business execution process;

[0046] Part 1: Configuration and debugging of each fusion device in the fusion device group;

[0047] like Figure 3 As shown, Figure 3It is a schematic diagram of parameter debugging of a fusion device group in a video processing system of a cloud-based intelligent fusion device according to the first embodiment of the present invention. The client 12 sends an access request to the cloud 16. When the cloud 16 passes the verification, the client 12 accesses the cloud 16 and selects whether to select a predefined mode from the candidate arrangement modes of each fusion device displayed by the cloud 16. When the predefined mode is selected, the parameters are input according to the predefined mode; when the predefined mode is not selected, the corresponding arrangement mode is determined from the historical arrangement modes and the parameters are input; if the required arrangement mode does not exist in the historical arrangement modes, the arrangement mode of each fusion device is created and the parameters are input for each fusion device in the arrangement mode;

[0048] The cloud 16 receives an access request from the client 12, and displays the candidate arrangement modes of each fusion device in the fusion device group 14 according to the access request. If the client 12 selects a predefined mode, the parameters input by the client 12 are received according to the predefined mode, and configuration information corresponding to each fusion device is generated according to the parameters. If the client 12 does not select a predefined mode, it is detected whether there is a corresponding historical arrangement mode for the arrangement mode selected by the client 12. When there is a historical arrangement mode corresponding to the arrangement mode selected by the client 12, the parameters input by the client 12 are received, and configuration information corresponding to each fusion device is generated according to the parameters. When there is no historical arrangement mode corresponding to the arrangement mode selected by the client 12, the arrangement mode set by the client 12 is created and saved, and configuration information corresponding to each fusion device is generated according to the set arrangement mode and the parameters input by the client 12. The cloud 16 is also used to store the configuration information and send the configuration information to the fusion device group 14.

[0049] The client 12 debugs each fusion device through the cloud 16 according to the display status of each fusion device until the debugging is completed.

[0050] In the embodiment of the present application, the configuration and debugging of each fusion device in the fusion device group 14 by the client 12 through the cloud 16 can be for the fusion device arrangement, resolution, fusion band size, projection correction value, etc., which are used to adjust the parameters required for the fusion device and playing the video (multimedia file in the embodiment of the present application).

[0051] like Figure 4 As shown, Figure 4 It is a flow chart of parameter configuration of a fusion device group in a video processing system of a cloud-based intelligent fusion device according to the first embodiment of the present invention. In the embodiment of the present application, after a user accesses the cloud 16 through a client 12, the user selects an arrangement mode of the fusion device through a predefined mode in the cloud 16. If there is a predefined mode and the user selects the predefined mode, the type of arrangement mode of each fusion device in the fusion device group is determined, wherein the type of arrangement mode may include a traditional rectangle, a diagonal superposition, and a herringbone superposition;

[0052] When the arrangement type is a traditional rectangle, the user inputs in the cloud 16 through the client 12: total resolution, number of rows and columns, and the number of the fusion device in the output area; arranged according to the rules, the projection area of ​​each fusion device is an average division of the total projection area, and default parameters are generated for each fusion device, such as the default position coordinates of the 1-1 device are 0, 0; the default position coordinates of the 1-2 device are weight.0; output the cutting related parameters of each fusion device, such as: the relative position in the output area and the size of the overlapping area, the video rotation angle, etc., save the parameters in the cloud 16, and send the parameters to the fusion device at the same time.

[0053] When the arrangement type is diagonal overlay, the user inputs: the size of the overlay area and the device position number in the cloud 16 through the client 12; according to the irregular arrangement, the projection area of ​​the fused device on the diagonal is an average division of the total projection area, the fused area only occurs on the diagonal, and the other parts are not fused, and default parameters are generated for each fused device, such as the position coordinates of the 1-1 device default to 0, 0; the default position coordinates of the 1-2 device are weight, height; output the cutting related parameters of each fused device, such as: the relative position and the size of the overlapping area in the output area, the video rotation angle, etc., save the parameters in the cloud 16, and send the parameters to the fused device at the same time.

[0054] When the arrangement type is a herringbone overlay, the user inputs in the cloud 16 through the client 12: setting the overlay area size and the device position number; according to the irregular arrangement, the first row of fusion devices only undergoes lower fusion, and the second row of fusion devices undergoes upper and left and right edge fusion at the same time, generating default parameters for each fusion device, such as the default position coordinates of the 1-1 device are width / 2, 0; the default position coordinates of the 2-1 device are 0, height; outputting the cutting-related parameters of each fusion device, such as: the relative position in the output area and the size of the overlapping area, the video rotation angle, etc., saving the parameters in the cloud 16, and sending the parameters to the fusion device at the same time.

[0055] If the user does not select a predefined mode, a similar mode is determined by searching the database of the cloud 16. If a similar mode already exists, the previously created similar mode is selected, necessary parameters are input, default parameters are generated for each fusion device according to different positions, and relevant cutting parameters of each fusion device are output, such as: the relative position of the output area and the size of the overlapping area, the video rotation angle, etc. The parameters are saved in the cloud 16 and sent to the fusion device at the same time.

[0056] If there is no existing similar pattern, a new pattern is created, and the new pattern is named and characterized. For example, the fusion devices are arranged at the vertices of a pentagonal area, and the middle area of ​​the pentagon is blank; the pattern is saved to the database for next use, and default parameters are generated for each fusion device according to different positions, and the cutting-related parameters of each fusion device are output, such as: the relative position in the output area and the size of the overlapping area, the video rotation angle, etc. The parameters are saved in the cloud 16, and the parameters are sent to the fusion device at the same time.

[0057] Part 2: Processing and updating the video in the fusion device group

[0058] Process the video in the fusion device group as follows Figure 5 As shown, Figure 5 is a schematic diagram of video processing and updating in a fusion device group in a video processing system based on a cloud-based intelligent fusion device according to an embodiment of the present invention. Figure 5 On the user side, the user logs in to the server through the client 12 to access the cloud 16, searches for the fusion device, and encrypts and uploads the film source to the server (i.e., the cloud 16 in the embodiment of the present application); on the cloud side, the cloud 16 receives the film source, searches for the corresponding fusion device, determines the parameters of the fusion device, prepares the media file, calls the server resources to process the video, and after the cutting is completed, the server notifies the fusion device to download; on the fusion device side, the fusion device checks for media file updates, downloads media files from the server (i.e., the cloud in the embodiment of the present application), updates the content list, and plays the multimedia file;

[0059] Update the video / content in the fusion device group such as Figure 5 As shown, based on the above process, on the client side, after encrypting and uploading the film source to the server, it is detected whether other devices need to be updated. If so, the fusion device is searched and encrypted and uploaded to the server.

[0060] In the embodiment of the present application, the process of video / content update in the fusion device includes not only updating the playlist but also:

[0061] 1. Start updating video content at a specific time in the future;

[0062] 2. Complete the update before a certain time start point;

[0063] 3. After the update is completed, start playing or stop specific content at a specific time point;

[0064] 4. After the update is completed, start the scheduled playback at a specific time point and stop all the contents in a certain playlist.

[0065] Among them, Figure 6 As shown, Figure 6 This is a schematic diagram of video cutting in a fusion device group in a video processing system of a cloud-based intelligent fusion device according to Example 1 of the present invention. It should be noted that in the embodiment of the present application, cutting is not a simple segmentation of the original video. For the projection fusion device, factors such as the fusion band size, brightness compensation, and projection deformation parameters also need to be considered.

[0066] In the embodiment of the present application, the cloud 16 reads the information of the fusion device group, such as the total resolution, arrangement mode, etc.; imports the video uploaded by the client 12, reads the Nth fusion device position, resolution; reads the fusion parameters of the fusion device; reads the fusion deformation parameters of the fusion device; reads the brightness compensation parameters of the fusion device, allocates server resources, generates video slices for specific fusion devices, encrypts the video slices using device keys, and sends the video slices to the corresponding fusion devices. If all devices have completed the cutting, it is determined that all files have been cut; if all devices have not completed the cutting, it returns to the processing step of reading the Nth fusion device position; if all files have not been cut, it returns to the processing step of importing the video uploaded by the client 12 until all devices have completed the cutting and all files have been cut.

[0067] In the video processing system of the cloud-based intelligent fusion device in the embodiment of the present application, when the fusion parameters are adjusted, they are immediately updated to the cloud server, and the subsequent cloud server can directly perform video-related operations according to the fusion parameters. When the content needs to be updated, the technician only needs to complete the video upload operation in the computer room through the network, without having to appear on site, which improves efficiency. When the fusion parameters of the fusion device change due to vibration, maintenance, etc., and the original video slice fails, the original video can be used on the server side for direct processing and downloaded to the relevant fusion device, saving time. The video update authority is uniformly checked by the cloud, which improves security. In order to speed up the processing of the video, the cloud server is usually equipped with multiple independent graphics cards, or uses cluster services to process the video. The efficiency of video processing is greatly improved and the waiting time of the operation is reduced. Because the video processing occurs in the cloud, the fusion display device only needs to have the most basic video decoding capability to work, which greatly reduces the cost of the fusion device. And because the cloud server serves many fusion devices at the same time, after its cost is shared, the deployment cost of the entire system can also be significantly reduced.

[0068] The present invention adopts the above technical solution, realizes remote debugging by debugging the fusion device group in the cloud and saving the debugging parameters in the cloud, and the video processing and updating of the fusion device group are also completed through cloud processing.
