The following is a brief description of the manner in which multi-angle freeview media data is generated as described herein. Specifically, firstly, an acquisition array can be set in an on-site acquisition area to perform synchronous acquisition of image frames at multiple angles, the acquisition array is composed of multiple acquisition devices, and synchronous acquisition is performed by using the acquisition array to perform simultaneous acquisition, so that the acquisition array can acquire multiple video data streams. After acquiring multiple video data streams, the acquisition array may send the multiple video data streams to a data processing device. And the data processing equipment respectively intercepts the synchronous image frames at the appointed video frame time in the multi-path video data streams and uploads the obtained multiple synchronous image frames corresponding to the appointed video frame time to the server.
After receiving the plurality of synchronous image frames corresponding to the designated frame time, the server may determine parameter data corresponding to the image combination and pixel data and depth data of each image frame in the image combination, using the plurality of synchronous image frames as an image combination. Then, based on the parameter data corresponding to the image combination, the pixel data and the depth data of the image frames in the image combination, performing image frame reconstruction on the image combination in a preset virtual viewpoint path to generate multi-angle free-viewing media data, where the multi-angle free-viewing media data includes: and multi-angle free visual angle space data and multi-angle free visual angle time data which are sequenced according to frame time. And finally, inserting the multi-angle free visual angle media data into a main video data stream of the play control equipment for transmitting to a play terminal for playing. The main video data stream may include any one of the multiple data streams acquired by the acquisition array, or may include a data stream that is continuously switched and selected to be continuously output among the multiple data streams.
The data presentation method provided by each embodiment of the present application is specifically described below through a specific application scenario.
As with the cast terminal 100 shown in fig. 1, in the user interface of the cast terminal 100, a first window 102 is playing a primary video data stream that shows the title "team a Vs team B". In the application scenario of the present application, the second window 104 may be presented when the proportion of the first window 102 in the user interface is not less than the first threshold. The user interface may include an interface of a player, and may also include a display interface of a playing device, which is not limited herein. Illustratively, the first threshold may include values of 70%, 80%, 95%, 100%, etc., and in the case that the first threshold is 100%, that is, the first window 102 is displayed in a full screen. In the above case, the second window 104 may be automatically presented in the user interface. As shown in fig. 1, a second window 104 may be shown floating on the first window 102 and used to show the multi-angle freeview media data. Of course, in other embodiments, the second window 104 may also be displayed in the user interface in an embedded manner, or displayed in parallel with the first window 102, which is not limited herein. In this application scenario, the second window 104 may display part of the multi-angle free-viewing media data, such as at least one representative image frame, and thus may be a static single image frame, or may dynamically broadcast multiple image frames in turn, or the like. As shown in fig. 1, the user may also click on the second window 104, so that the presentation content of the first window 102 is switched to the presentation content of the second window 104, and thus, the user may view the multi-angle free-viewing media data through a large screen. Of course, after the user clicks the second window 104, the user may also trigger the second window 104 to be enlarged, so that the second window 104 is displayed in a large screen. As shown in fig. 2, when the multi-angle free-viewing angle media data is displayed on a large screen, the video frame time and title corresponding to the multi-angle free-viewing angle media data can be displayed, and in addition, a "closing" control can be further provided, so that a user can conveniently close the multi-angle free-viewing angle media data and return to the play display of the main video data stream.
As shown in fig. 3, the second window 104 may also include a video toggle control, i.e., the "more" control in fig. 3. By clicking the 'more' control, the user can browse the multi-angle free visual angle media data corresponding to all the video frame moments corresponding to the main video data stream. After the user clicks the trigger "more" control, the content presented by the user interface may be switched to the content shown in fig. 4. As shown in fig. 4, a third window 402 is shown on the first window 102, and the third window 402 includes a plurality of sub-windows 404, where the sub-windows 404 are respectively used for showing multi-angle free-view media data corresponding to different video frame times. The sub-window 404 is also provided with a corresponding video frame time and title. In addition, the third window 402 can also be slid to browse the multi-angle free-view media data corresponding to all the video frame times. In some examples, a user may view corresponding multi-angle freeview media data in a large screen by clicking on sub-window 404. Of course, in other examples, the third window 402 may also be the second window 104 after enlargement.
As shown in fig. 5, a play progress control 502 of the main video data stream may also be shown in the user interface, and a mark 504 is set at a position corresponding to the at least one video frame time of the play progress control 502. Thus, the user can quickly know which moments have corresponding multi-angle free-viewing media data. In addition, the mark 504 may also be a trigger control, and by clicking the mark 504, the multi-angle free-view media data corresponding to the mark may be displayed.
As shown in fig. 6, a trigger control 602 may be further displayed in the user interface, and the trigger control 602 may control to open or close displaying of the multi-angle free-viewing media data, so that the user may conveniently and globally control the playing and displaying of the multi-angle free-viewing media data.
The data presentation method described in the present application is described in detail below with reference to the drawings. Fig. 7 is a schematic method flow diagram of an embodiment of a data presentation method provided in the present application. Although the present application provides method steps as shown in the following examples or figures, more or fewer steps may be included in the method based on conventional or non-inventive efforts. In the case of steps where no necessary causal relationship exists logically, the order of execution of the steps is not limited to that provided by the embodiments of the present application. The method can be executed in sequence or in parallel according to the method shown in the embodiment or the figures when the method is executed in an actual data presentation process or a device (for example, a parallel processor or a multi-thread processing environment).
Specifically, as shown in fig. 7, an embodiment of the data presentation method provided in the present application may include:
s701: and playing and displaying a main video data stream in the first window, wherein the main video data stream corresponds to multi-angle free visual angle media data at least one video frame moment.
S703: in an instance in which it is determined that the occupancy of the first window in a user interface is not less than a first threshold, presenting at least part of the multi-angle freeview media data in a second window whose occupancy in the user interface is not greater than a second threshold.
As described above, the main video data stream may include any one of the multiple data streams acquired by the acquisition array, or may include a data stream that is switched and selected to be continuously output among the multiple data streams. In one example, in a basketball game, tens or even hundreds of cameras may be arranged in the game scene to capture image frames of the game scene from different angles, respectively, in order to obtain multi-angle free-viewing media data. Then, the multi-angle freeview media data may be generated in the manner provided by the above-described embodiments. In addition, the data stream acquired by any of the above-mentioned image capturing devices may also be selected as the main video data stream, for example, the path with the best shooting angle is used as the main video data stream. Of course, it is also possible to switch the playback between the multiple data streams, as far as possible, so that each image frame of the main video data stream exhibits the most wonderful angle of the match scene.
In the embodiment of the present application, the main video data stream corresponds to multi-angle free-view media data at least one video frame time, and the generation manner of the multi-angle free-view media data may refer to the above-mentioned embodiment, which is not described herein again. It should be noted that the playing mode of the main video data stream may include live broadcasting, on-demand broadcasting and the like, and the present application is not limited herein. In an embodiment of the present application, in the process of playing and presenting the main video data stream, at least part of the multi-angle free-viewing media data may be presented in case that a trigger condition is met. According to the generation method of the multi-angle free-view media data, the multi-angle free-view media data is composed of image frames of multiple angles, and at least part of the multi-angle free-view media data may include part of the image frames of the multiple angles, such as representative image frames, or a dynamic image composed of several selected image frames, such as a GIF format image.
In the embodiment of the application, the main video data stream can be displayed in a first window in a playing mode, and at least part of the multi-angle free-viewing-angle media data is displayed in a second window under the condition that the proportion of the first window in a user interface is determined to be not less than a first threshold value. In one embodiment, the user interface may include a display interface of a player, and of course, the display interface of the player may be a full-screen display or a non-full-screen display. In another embodiment, the user interface may include an interface of a display of a playback device. That is, where the first window is large enough, the second window may be presented. Exemplarily, the first threshold may include 70%, 80%, 95%, 100%, etc., and in case that the first threshold is 100%, that is, the first window is displayed in a full screen, for example, in case that the playing device is displayed in a landscape screen, the first window is displayed in a full screen. It should be noted that the second window needs to be presented in the user interface in a small window style, and for example, the second threshold may include a value of 20%, 10%, 5%, and the like, which is not limited herein.
In the embodiment of the present application, for the display style of the first window and the second window, the second window may be disposed on the first window in a floating manner, and in one example, a small-sized floating second window may be disposed on the first window. In another way, the second window may be displayed in the first window in an embedded manner. In other embodiments, the first window may also be displayed in parallel with the first window, and the present application does not limit the display style of the first window and the second window. It should be noted that the second window may have various parameters such as size, transparency, position, color, and the like, and the various parameters may be default settings or user-defined settings, which is not limited herein.
In an embodiment of the application, under the condition that it is determined that the occupation ratio of the first window in the user interface is not less than a first threshold value, that is, the first window is displayed in a large screen, it may be determined whether to download at least part of the multi-angle free viewing angle video data. In a case where at least part of the multi-angle free-view media data is downloaded, the multi-angle free-view media data may be displayed in the second window. In this embodiment, when at least a part of the data stream of the multi-angle free-viewing angle media data is acquired, the downloaded multi-angle free-viewing angle media data can be directly displayed without being triggered by a user.
In an embodiment of the present application, when the main video data stream is played to a first video frame time, the multi-angle free-view media data corresponding to the first video frame time may be displayed at the first video frame time. For example, during playing the main video data stream, at the time of playing to 10 minutes and 45 seconds, the playing terminal corresponds to the multi-angle freeview media data at the time, and therefore, at least part of the multi-angle freeview video can be displayed at the time of 10 minutes and 45 seconds. For a specific display manner, referring to the above embodiment, for example, the second window is popped up in the first window, and the multi-angle free view video is displayed in the second window, which is not described herein again.
In an embodiment of the present application, at least a portion of multi-angle free-view media data corresponding to the video frame time of the latest history may be displayed in the second window. For example, the current playing progress of the main video data stream is 30 minutes and 45 seconds, and the historical latest video frame time is 29 minutes and 03 seconds, so that at least part of multi-angle free-viewing media data corresponding to 29 minutes and 03 seconds can be displayed in the second window. Through the display mode, the user is not puzzled.
In one embodiment, at least one image frame may be extracted from the multi-angle freeview media data and presented in the second window in the process of presenting at least part of the multi-angle freeview media data in the second window. The extracted at least image frames may include image frames corresponding to representative angles in the multi-angle freeview media data, such as image frames corresponding to side angles of a player pitching a ball. The manner of extracting the at least one image frame is not limited herein.
In the embodiment of the application, a trigger control corresponding to the multi-angle free-view media data may be further set in the first window, and the trigger control has a function of opening or closing the display of the multi-angle free-view media data. In this way, the user can strictly control the presentation or non-presentation of the multi-angle freeview media data. In some examples, for example, when the main video data stream is played to a specified video frame time by default, the play terminal automatically pops up and displays the multi-angle free-view media data corresponding to the specified video frame time. In this case, the presentation function of the multi-angle free-viewing media data may be closed through the trigger control. In another example, the user may also select to open the trigger control, such that after receiving an opening operation of the user, at least part of the multi-angle freeview media data may be presented in the second window in response to the opening operation if the occupation ratio of the first window in the user interface is not less than a first threshold. Of course, in other embodiments, the function of presenting the multi-angle freeview media data may be turned on or off in other manners. The mode may include a preset operation in the user interface, where the preset operation may include operations such as voice, gesture, and gesture. The playing device for viewing includes not only a flat player, such as a smart phone, a tablet computer, a laptop computer, a desktop computer, etc., but also a playing device in a virtual reality environment, such as viewing after wearing VR glasses, etc. Based on this, the multi-angle free visual angle media data can be displayed through voice triggering, such as a voice instruction of 'bullet opening time', and in other embodiments, preset operations such as clicking, double clicking, long pressing, sliding and the like can be performed on a touch display screen with a playing device to display the multi-angle free visual angle media data. And in a virtual environment, the multi-angle free visual angle media data can be triggered and displayed through gestures, gestures and expressions. The gesture may include, for example, a jump, a turn, a gesture, and the like, and the gesture may include a heart, a hand, an OK, a clap, and the like, which are not limited herein.
In an embodiment of the present application, a first video switching control may be disposed in the second window, and the first video switching control is used to trigger the multi-angle free time video data to be displayed in the first window. In an example, when the second window is a floating small window displayed on the first window, a video switching control may be disposed in the floating small window, and a user may switch the content displayed by the first window to the multi-angle free-viewing-angle media data by operating the video switching control, so that the user may view the multi-angle free-viewing-angle media data in a large screen conveniently.
In an embodiment of the present application, a second video switching control may be disposed in the second window, where the second video switching control may be configured to trigger setting of a plurality of sub-windows in the second window, and the plurality of sub-windows are respectively configured to display multi-angle free-view media data corresponding to the at least one video frame time. In some practical applications, a user may want to browse multi-angle freeview media data corresponding to all video frame times. Therefore, through the second video switching control, a plurality of sub-windows can be set in the second window, and the multi-angle free view media data corresponding to the at least one video frame moment can be respectively displayed by using the plurality of sub-windows. In an embodiment, since the number of the video frame times is larger, the size of the second window may be increased to display the multi-angle freeview media data corresponding to all the video frame times as much as possible. In one example, the switched second window may be set to cover half of the screen, to be presented right or left, and a plurality of sub-windows may be set in the second window, which may be set with a title, and a corresponding video frame time. Of course, the second window may further include parameters such as transparency, color, and the like, and the application is not limited herein.
Of course, in other embodiments, the displaying at least part of the multi-angle freeview media data in the second window by the second window may include: and setting a plurality of sub-windows in the second window, wherein the sub-windows are respectively used for displaying multi-angle free visual angle media data corresponding to the at least one video frame moment. Namely, the plurality of child windows are not required to be directly displayed through switching the control.
In an embodiment of the present application, a third video switching control may be respectively disposed in the multiple sub-windows, where the third video switching control is used to trigger displaying of multi-angle free time video data corresponding to the sub-windows in the first window. In this embodiment, by operating the third video switching control, the multi-angle free time video data corresponding to the child window can be displayed on a large screen, so that the user viewing experience is improved.
In an embodiment of the present application, the second window may be closed in case of presentation of the at least part of the multi-angle freeview media data. In one embodiment, the second window may be automatically closed after two seconds from the presentation of the at least part of the multi-angle free-view media data, so as to prevent the second window from obstructing the user from viewing the main video data stream.
In an embodiment of the present application, a play progress control of the main video data stream may also be shown, and a mark is set at a position corresponding to the at least one video frame time of the play progress control. The playing progress control can be displayed at any position of the playing interface, such as the lowest position, the highest position and the like of the playing interface. The marks may include distinctive marks such as dots, vertical bars, etc., by which the user can clearly understand the video frame time corresponding to the multi-angle freeview media data. In addition, under the condition that a mouse is contacted with the mark or a finger is contacted with the mark, the brief introduction of the multi-angle free visual angle media data corresponding to the video frame time can be also realized, such as titles of 'Xiaoyi peer-learning and fang', and the like.
In an embodiment of the application, the mark may include a trigger control, based on which a preset operation of a user on the mark may be received, and then, in response to the preset operation, at least a portion of the multi-angle free-view media data corresponding to the mark is displayed. In one example, a user may click on the mark, i.e., may view at least a portion of the multi-angle freeview media data corresponding to the mark. The displaying mode may include switching a window displaying the main video data stream to display the at least part of the multi-angle free-viewing media data, and of course, the at least part of the multi-angle free-viewing media data may also be displayed in a new window, which is not limited herein.
The data display method can automatically display at least part of multi-angle free visual angle videos corresponding to the main videos through small windows under the condition that the main video data streams are displayed through large windows. By the display mode, a user can watch some scenes, such as some wonderful moments, by freely switching the viewpoint position in the process of watching the video, and therefore the watching experience of the user is greatly improved.

In another aspect, the present application further provides a computer-readable storage medium, on which computer instructions are stored, and the instructions, when executed, implement the steps of the method according to any of the above embodiments.
The computer readable storage medium may include physical means for storing information, typically by digitizing the information for storage on a medium using electrical, magnetic or optical means. The computer-readable storage medium according to this embodiment may include: devices that store information using electrical energy, such as various types of memory, e.g., RAM, ROM, etc.; devices that store information using magnetic energy, such as hard disks, floppy disks, tapes, core memories, bubble memories, and usb disks; devices that store information optically, such as CDs or DVDs. Of course, there are other ways of storing media that can be read, such as quantum memory, graphene memory, and so forth.
In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhal (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: the ARC625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.
