It will of course be appreciated that in the development of any such actual embodiment, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with system-related and business-related constraints, which will vary from one implementation to another. Moreover, it will be appreciated that such a development effort might be complex and time-consuming, but would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure.
It should be noted that, in order to avoid obscuring the present invention with unnecessary details, only the device structures and/or processing steps closely related to the solution according to the present invention are shown in the drawings, and other details not so relevant to the present invention are omitted.
Fig. 1 illustrates an exemplary process of the above-described view-adjustable video playing method.
It should be noted that, in the embodiment of the present invention, the highlight angle refers to a playing angle corresponding to a highlight in the panoramic video frame, where the highlight is, for example, a picture including a specified object, and the specified object is, for example, a certain scenery spot, a certain target (such as a statue, a building, etc.), a certain person, etc. In addition, the number of designated objects included in the highlight may be one or more.
As shown in fig. 1, in step S1, panoramic video data is acquired. Then, step S2 is executed.
In step S2, a highlight angle parameter is added to a panoramic video frame in the panoramic video data, and a profile containing the parameter set is formed. Then, step S3 is executed.
As an example, in step S2, the profile is, for example, an editable format, and one or more profiles, the user may select a profile when watching the panoramic video, the profile enables the panoramic video to automatically change the playing angle according to different contents, adjust the user angle to a highlight angle, and add the same or different highlight angle parameters to a certain segment or several segments of the same panoramic video source, as shown in table one.
Watch 1
Wherein the video frame sequences M1, M2, … and MS represent S video frame sequences in the same panoramic video source, S being, for example, 1, 2 or more.
The profiles 1, 2, …, N indicate N profiles corresponding to the panoramic video source, where N is, for example, 1 or more.
In addition, at least a portion of the sequence of video frames in the profile is configured with a highlight view parameter.
For example, only a certain segment, i.e. a certain video frame sequence, may be configured with the view parameter, while the rest of the video frame sequences are not configured.
For another example, only a few segments, i.e., a few video frame sequences, may be configured with the view parameters, while the remaining video frame sequences are not configured.
Alternatively, the view parameters may be configured for all video frame sequences in the configuration file.
Furthermore, the highlight parameters for the same sequence of video frames in multiple profiles may be the same or different.
As an example, different highlight parameters may also be added to each frame or several frames of the sequence of video frames MS, as shown in table two.
Watch two
Wherein MSI1, MSI2, …, MSIw represent the w frames in the sequence of video frames MS (it should be understood that MSI1 does not necessarily represent the first frame of the sequence, but one of the w frames). The sequence of video frames MS corresponds to N profiles, i.e. profiles 10, 20, …, N0, where N is for example 1 or more.
As shown in fig. 1, after step S2 is completed, when a highlight playing instruction of the panoramic video is received, the panoramic video may be played according to a configuration file corresponding to the instruction in step S3.
As an example, the highlight playback instruction received in S3 includes, for example, an auto mode playback instruction and a non-auto mode playback instruction. When receiving a highlight playing instruction of a user, firstly, judging whether the triggering instruction of the user is an automatic mode playing instruction or a non-automatic mode playing instruction.
As an example, if the instruction is an automatic mode playing instruction, when the user slides the screen to watch the panoramic video, if the user does not interact with the playing device (such as video playing software) for a long time, the judgment is made by n seconds (n is, for example, 2 seconds, 3 seconds, 5 seconds, 10 seconds, or the like) between two preset input instructions, and if the user does not operate the playing device for more than n seconds, the highlight angle playing instruction is automatically triggered; at this time, the playing device firstly determines a triggering time point and a user visual angle during triggering, and then searches and automatically matches a wonderful visual angle, which is closest to the user visual angle, of the triggering time point in a plurality of configuration files to play the panoramic video.
For example, the method for determining the highlight perspective closest to the user perspective at the trigger time point comprises: and judging and searching the maximum value of the overlapping part of the display area S0 corresponding to the user visual angle of the trigger time point and the display areas (S1, S2, … …, SN) corresponding to all the wonderful visual angles of the trigger time point.
As an example, a prompt may be given when the overlapping portions are both 0, for example.
For example, if the user initially selects the wonderful view angle automatic mode for playing in the panoramic video, the user view angle is projected to the spherical surface, and if the playing view angle parameter at a certain moment in the panoramic video is the spherical attitude angle (80 degrees and 30 degrees), the video picture corresponding to the angle is the deer run-through; if the user does not operate the playing device for more than n seconds, the playing device confirms that the playing mode enters a wonderful visual angle automatic mode, determines that the triggering time point and the user visual angle parameter during triggering are spherical attitude angles (70 degrees and 25 degrees), and the corresponding display area is S0; and the display areas corresponding to all the wonderful viewing angles at the triggering time point in the configuration file are (S1, S2, … …, SN), the overlapping part of S1 and S0 is 30%, the overlapping part of S2 and S0 is 50%, the overlapping part of S3 and S0 is 80%, and the overlapping part of the display areas corresponding to the remaining wonderful viewing angles and the display area S0 corresponding to the user viewing angle is 0, then the wonderful viewing angle corresponding to S3, such as the spherical attitude angle (80 °, 30 °) mentioned above, is selected, the playing device plays the panoramic video according to the configuration file in which the wonderful viewing angle is located, and the playing device continues to play the panoramic video according to the configuration file on the premise that the user does not trigger any other playing instruction.
In addition, for example, if the command is a non-automatic mode playback command, the user inputs a selection (for example, a selection may be made by a button displayed on the screen or the like) of a certain profile, and the playback device plays back the panoramic video according to the profile. In this mode of playback, the user can manually select different profiles to view different highlights at the same time.
For example, a user view angle is projected to a spherical surface, a spherical attitude angle at a certain moment when the user watches the panoramic video is (90 degrees and 80 degrees), a video picture corresponding to the angle can only see a piece of sky, at the moment, the user triggers a highlight view angle non-automatic mode playing instruction, a user button inputs and selects a configuration file N, at the moment, a highlight picture corresponding to the trigger time point in the configuration file N runs through a fawn, a highlight view angle corresponding to the highlight view angle is (60 degrees and 60 degrees), the current user view angle is adjusted to (60 degrees and 60 degrees), and the playing device continues to play the panoramic video according to the configuration file N on the premise that the user does not trigger any other playing instructions.
It should be noted that, when the panoramic video enters the wonderful viewing angle for playing, the user can enter the panoramic video sliding screen for playing through the interaction with the playing device at any time.
In addition, the user perspective and the highlight perspective may take a variety of forms of presentation, such as coordinates, pose angles, spatial vectors, and the like.
Furthermore, it should be noted that one of the differences between the highlight automatic mode playback and the non-automatic mode playback is as follows: when the automatic mode is played, one or more configuration files which contain the trigger time point and are closest to the user view angle can be searched in the plurality of configuration files, and when more than two configuration files exist, the playing device is matched with one configuration file at random for playing; and when the user does not play in the automatic mode, the user manually selects different configuration files to play.
Therefore, the scene pictures watched by the same user when the same panoramic video is watched and the wonderful visual angle mode is triggered at different angles and different moments are different; because the video source file is not modified, the viewing angle is adjusted correspondingly by the playing device according to different trigger modes, and the interest and experience of watching the panoramic video by the user are enhanced.
In addition, the embodiment of the invention also provides a video playing device capable of adjusting the visual angle.
Fig. 2 is a block diagram showing an example of the above-described view-adjustable video playback apparatus.
As shown in fig. 2, the apparatus for playing a video with adjustable viewing angle includes a video capturing unit 210, an adding unit 220, and a playing unit 230.
As shown in fig. 2, the video acquisition unit 210 may acquire panoramic video data. Next, the adding unit 220 may add a highlight view parameter to a panoramic video frame in the panoramic video data, and form a configuration file containing the parameter set.
In this way, when receiving a highlight playing instruction of the panoramic video, the playing unit 230 may play the panoramic video according to a configuration file corresponding to the instruction.
As an example, the configuration files are, for example, in an editable format, and are one or more, a user may select one of the configuration files when viewing the panoramic video, and the playing unit 230 may cause the panoramic video to automatically change the playing angle according to different contents, adjust the user angle to a highlight angle, and add the same or different highlight angle parameters to one or several segments of the same panoramic video source, as shown in table one described above.
It should be noted that only a certain segment, i.e., a certain video frame sequence, in the configuration file may be configured with the view parameter, while the rest of the video frame sequences are not configured.
In addition, only a plurality of segments, namely a plurality of video frame sequences, can be configured with the view angle parameters, and the rest video frame sequences are not configured; alternatively, the view parameters may be configured for all video frame sequences in the configuration file.
Furthermore, the highlight parameters for the same sequence of video frames in multiple profiles may be the same or different.
As an example, the adding unit 220 may also add different highlight parameters to each frame or several frames in the sequence of video frames MS, as shown in table two described above.
As an example, the highlight playback instruction received by the playback unit 230 includes, for example, an auto mode playback instruction and a non-auto mode playback instruction. When receiving a highlight play instruction from a user, the play unit 230 first determines whether the trigger instruction of the user is an automatic mode play instruction or a non-automatic mode play instruction.
As an example, if the instruction is an auto mode play instruction, when the user slides the screen to view the panoramic video, if the user does not interact with the playing device (the playing device may be, for example, a smart phone of the user) for a long time, the playing unit 230 may determine that the time interval n seconds between two preset input instructions is long (n is, for example, 2 seconds, 3 seconds, 5 seconds, or 10 seconds), and if the user does not operate the playing device for more than n seconds, automatically trigger the highlight angle play instruction; at this time, the playing unit 230 first determines the trigger time point and the user viewing angle at the time of the trigger, and then searches and automatically matches the highlight viewing angle at the trigger time point closest to the user viewing angle in the plurality of configuration files to play the panoramic video.
For example, the method for the playing unit 230 to determine the highlight angle with the trigger time point closest to the user angle is as follows: and judging and searching the maximum value of the overlapping part of the display area S0 corresponding to the user visual angle of the trigger time point and the display areas (S1, S2, … …, SN) corresponding to all the wonderful visual angles of the trigger time point.
As an example, the playing unit 230 may give a prompt when the overlapping portions are both 0, for example.
For example, if the user initially selects the wonderful view angle automatic mode for playing in the panoramic video, the user view angle is projected to the spherical surface, and if the playing view angle parameter at a certain moment in the panoramic video is the spherical attitude angle (80 degrees and 30 degrees), the video picture corresponding to the angle is the deer run-through; if the user does not operate the playing device for more than n seconds, the playing device confirms that the playing mode enters a wonderful visual angle automatic mode, determines that the triggering time point and the user visual angle parameter during triggering are spherical attitude angles (70 degrees and 25 degrees), and the corresponding display area is S0; and the display areas corresponding to all the wonderful viewing angles at the triggering time point in the configuration file are (S1, S2, … …, SN), the overlapping part of S1 and S0 is 30%, the overlapping part of S2 and S0 is 50%, the overlapping part of S3 and S0 is 80%, and the overlapping part of the display areas corresponding to the remaining wonderful viewing angles and the display area S0 corresponding to the user viewing angle is 0, then the wonderful viewing angle corresponding to S3, such as the spherical attitude angle (80 °, 30 °) mentioned above, is selected, the playing device plays the panoramic video according to the configuration file in which the wonderful viewing angle is located, and the playing device continues to play the panoramic video according to the configuration file on the premise that the user does not trigger any other playing instruction.
Further, as an example, if the instruction is a non-automatic mode playing instruction, the user inputs a selection (for example, a selection may be made through a button displayed on a screen or the like) to a certain profile, and the playing unit 230 may play the panoramic video according to the profile. In this mode of playback, the user can manually select different profiles to view different highlights at the same time.
For example, a user view angle is projected to a spherical surface, a spherical attitude angle at a certain moment when the user watches the panoramic video is (90 degrees and 80 degrees), a video picture corresponding to the angle can only see a piece of sky, at the moment, the user triggers a highlight view angle non-automatic mode playing instruction, a user button inputs and selects a configuration file N, at the moment, a highlight picture corresponding to the trigger time point in the configuration file N runs through a fawn, a highlight view angle corresponding to the highlight view angle is (60 degrees and 60 degrees), the current user view angle is adjusted to (60 degrees and 60 degrees), and the playing device continues to play the panoramic video according to the configuration file N on the premise that the user does not trigger any other playing instructions.
It should be noted that, when the panoramic video enters the wonderful viewing angle for playing, the user can enter the panoramic video sliding screen for playing through the interaction with the playing device at any time.
In addition, the user perspective and the highlight perspective may take a variety of forms of presentation, such as coordinates, pose angles, spatial vectors, and the like.
Furthermore, it should be noted that one of the differences between the highlight automatic mode playback and the non-automatic mode playback is as follows: when the automatic mode is played, one or more configuration files which contain the trigger time point and are closest to the user view angle can be searched in the plurality of configuration files, and when more than two configuration files exist, the playing device is matched with one configuration file at random for playing; and when the user does not play in the automatic mode, the user manually selects different configuration files to play.
Therefore, the scene pictures watched by the same user when the same panoramic video is watched and the wonderful visual angle mode is triggered at different angles and different moments are different; because the video source file is not modified, the viewing angle is adjusted correspondingly by the playing device according to different trigger modes, and the interest and experience of watching the panoramic video by the user are enhanced.
