It should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.
With continued reference to FIG. 2, a flow 200 of one embodiment of a video generation method according to the present application is shown. The video generation method is used for a first terminal and comprises the following steps:
step 201, sending a video request to at least one second terminal, where the video request carries a shooting parameter and a user identity corresponding to the first terminal, a distance between a position of the first terminal and a position of the at least one second terminal is less than a target distance, and the user identity corresponding to the first terminal is different from the user identity corresponding to the second terminal.
In this embodiment, an execution subject of the video generation method (e.g., a terminal device shown in fig. 1) may transmit a video request to at least one second terminal. Here, the distance between the first terminal and the second terminal is small, so that videos shot by the first terminal and the second terminal can be well combined. In some embodiments, the shooting parameter is a parameter that can be supported by the hardware device to shoot the video corresponding to the video request, and may include, but is not limited to, a resolution of a camera, a bitrate of the video (including a bitrate of audio in the video), and/or a frame rate of the video.
The user identity corresponding to the terminal may include, but is not limited to, an identity of a login user corresponding to an account logged in at the terminal. The account here may be an account of any application or any platform. For example, the user id may be a user id registered on the target social platform. In this embodiment, the user identities corresponding to different terminals may be different.
In practice, the execution main body sends the video request to the second terminal, and the video request may be sent to the second terminal directly through a local area network (such as a mobile hotspot or bluetooth). The video request may carry information indicating each of the at least one second terminal, such as an identifier of the at least one second terminal.
In some optional implementation manners of this embodiment, the user identity corresponding to the first terminal and the user identity corresponding to the at least one second terminal are friend relationship identifiers on the target social platform, and the user identity corresponding to the first terminal and the user identity corresponding to the at least one second terminal are in the same social session on the target social platform; and step 201 may comprise: within the social session, a video request is initiated. In some embodiments, the user identity corresponding to the first terminal and the user identity corresponding to the at least one second terminal are in the same social session on the target social platform, but the user identity corresponding to the first terminal and the user identity corresponding to the at least one second terminal are not friend relation identities.
In these optional implementations, the user logged in at the first terminal and each user logged in at the at least one second terminal are in a friend relationship on the target social platform. Moreover, the user id corresponding to the first terminal may be in a social session with the user ids corresponding to different second terminals, that is, the user logged in the first terminal and the user logged in each second terminal are in a one-to-one social session. In addition, the user id corresponding to the first terminal may also be in a social session with multiple user ids (for example, all user ids) in the user id corresponding to the at least one second terminal. That is, the user who logs in at the first terminal may be in a social session with group chat with a plurality of users among the users who log in at least one second terminal.
In practice, the video request may be initiated in the one-to-one social session or the social session of the group chat. The video request may be a segment of text, or a trigger button for starting the second terminal to determine whether the first terminal and the second terminal are matched, or a trigger button for generating information for receiving the video request.
The realization modes can ensure that the video information is not leaked and the recording process is smoothly carried out by carrying out the related operation of video synthesis between the devices of the users which are known mutually, thereby avoiding that irrelevant personnel interrupt the shooting and synthesizing process of the video or acquire the information of the devices or the video.
In some optional implementations of this embodiment, a height difference between the first terminal and the at least one second terminal is less than or equal to the target value.
In these optional implementation manners, the height difference between the first terminal and the second terminal is smaller when the first terminal shoots the video, so that the size, the angle, the light and the like of an object participating in the synthesized video are prevented from being obviously different due to the larger difference of shooting positions by controlling the horizontal distance and the vertical height difference between the shooting devices, and the synthesized video has a stable picture effect which is closer to the shooting of the same terminal.
Step 202, in response to determining that the first terminal is matched with the at least one second terminal, shooting a video, and receiving a video to be synthesized transmitted by the at least one second terminal, wherein the video to be synthesized conforms to the shooting parameters.
In this embodiment, if it is determined that the first terminal matches each of the at least one second terminal, the execution subject may capture a video. In addition, the execution body may further receive a video to be synthesized transmitted by the at least one second terminal. The video to be synthesized can be shot by the second terminal, and the shooting time of the video shot by the first terminal and the shooting time of the video shot by the second terminal can be overlapped. In practice, the video shooting of the first terminal may be triggered by a shooting trigger operation performed by the user on the first terminal, or may be performed directly after the first terminal determines that the first terminal is matched with the at least one second terminal.
In particular, the executing entity may determine that the first terminal matches the at least one second terminal in a variety of ways. For example, the executing entity may determine that the first terminal matches with the at least one second terminal after receiving matching information sent by other electronic devices, such as the at least one second terminal. In addition, the execution subject may also obtain hardware data of at least one second terminal in the local or server, where the hardware data may be a machine model and the like. Then, the execution main body may determine whether the first terminal is capable of shooting the video corresponding to the video request, and specifically may directly determine locally or display the hardware data to a user for determination, so that a determination result may be obtained. And if the judgment result is that the shooting can be carried out, determining that the first terminal is matched with the at least one second terminal.
In some optional implementations of this embodiment, step 201 may include: sending a video request to at least one second terminal so that the at least one second terminal determines whether the first terminal passes verification and/or determines whether hardware parameters of the second terminal support shooting parameters or not based on a user identity corresponding to the first terminal; and capturing a video in response to determining that the first terminal matches the at least one second terminal in step 202 may include: and shooting the video in response to receiving the matching information, wherein the matching information indicates that the first terminal passes the verification and/or the hardware parameters of the second terminal support the shooting parameters.
In these alternative implementations, each second terminal may determine whether the first terminal and the second terminal match, and if the first terminal and the second terminal match, generate matching information indicating the matching relationship, and send the matching information to the first terminal. In this way, the first terminal may capture a video after receiving the matching information sent by the at least one second terminal.
Specifically, the second terminal may determine whether the first terminal passes the authentication based on the user identity corresponding to the first terminal, and in a case that the first terminal passes the authentication, determine the matching. Here, if the user identity corresponding to the first terminal and the user identity corresponding to the second terminal are in a friend relationship and/or in a social session, it may be determined that the first terminal is authenticated. And the second terminal can also determine matching under the condition that the hardware parameter of the second terminal supports the shooting parameter. Further, the second terminal may also determine the match in the case where it is determined that the authentication is passed and it is determined that the above-described photographing parameters are supported. The hardware parameter may be, for example, the resolution of the camera, and may further include a performance parameter of the processor, and the like.
The realization modes can judge whether the first terminal is matched with the second terminal from various aspects through the conditions of identity verification, hardware parameters and the like, thereby improving the judgment accuracy, avoiding the interruption of the shooting and synthesizing processes of the video by irrelevant personnel, and ensuring the higher quality of the video by limiting the hardware parameters.
And 203, synthesizing the shot video and at least one video to be synthesized to obtain a panoramic video.
In this embodiment, the executing body may synthesize the captured video and the received at least one video to be synthesized into a panoramic video. The panorama image covers a larger view field angle and contains more shooting contents. In practice, the execution subject described above may perform video composition in various ways. For example, the execution body may directly connect the videos end to end.
In some optional implementations of this embodiment, the synthesizing the captured video and the at least one video to be synthesized in step 203 may include: determining a shot video and a superposed video frame of each video to be synthesized in at least one video to be synthesized, wherein the superposed video frame is a video frame with the similarity larger than a preset threshold value; and synthesizing the shot video and at least one video to be synthesized by taking the superposed video frame as a reference.
In these alternative implementations, the executing entity may determine a video shot by the first terminal, and a video frame coinciding with each video in the at least one video to be synthesized. Then, the execution subject may synthesize the video captured by the first terminal and the video to be synthesized, with a superimposed video frame in the video to be synthesized as a reference, for each video to be synthesized.
Specifically, the executing body may search, for each video frame of the video shot by the first terminal, a video frame with the largest similarity and the similarity being greater than a similarity threshold value in the video to be synthesized, and use the video frame as a video shot by the first terminal and a corresponding coincident video frame in the video to be synthesized. In addition, the executing body may also perform the above search process in the video shot by the first terminal for each video frame in the video to be synthesized, so as to obtain a coincident video frame.
In practice, the execution body described above may be synthesized with the coincident video frames as references in a variety of ways. For example, the overlapped video frame in the video to be synthesized may be removed, and the video frames other than the overlapped video frame in the video to be synthesized may be connected to the video shot by the first terminal. In addition, the overlapped video frame in the video shot by the first terminal can be removed, and the video frame except the overlapped video frame in the video shot by the first terminal is connected with the video to be synthesized.
These implementations can accurately find the coincident video frames by similarity, thereby synthesizing an accurate panoramic video based on the coincident video frames.
In some optional application scenarios of these implementations, the synthesizing the captured video and the at least one video to be synthesized by using the overlapped video frame as a reference may include: and carrying out image fusion on every two corresponding superposed video frames in the shot video and the video to be synthesized.
In these optional application scenarios, the execution subject may perform image fusion on the overlapped video frame in the video shot by the first terminal and the overlapped video frame in the corresponding video to be synthesized.
The application scenes can enable the synthesized video to be more natural and smooth, and avoid hard-to-live connection at the video splicing part.
In some optional implementations of this embodiment, the method may further include: and publishing the panoramic video to a social space of the target social platform.
In these alternative implementations, the execution subject may post the synthesized panoramic video in the social space of the target social platform. The social space may be, for example, a social conversation, or may be a space for posting personal status information or comments, etc. In particular, panoramic video may be published to social spaces as posts or live video.
The implementation modes can release the panoramic video in the social space, so that users can share the synthesized video, and the application universality of the scheme is improved.
In some optional implementations of this embodiment, the method may further include: determining a bandwidth required for real-time transmission of a video shot using the shooting parameters; selecting a communication link conforming to the bandwidth from the candidate communication links as a target communication link, and sending target communication link information indicating the target communication link to at least one second terminal, wherein each second terminal has a corresponding target communication link; and receiving the video to be synthesized transmitted by at least one second terminal, wherein the video to be synthesized comprises: and receiving the video to be synthesized transmitted by at least one second terminal in real time through the target communication link.
In these alternative implementations, the executing entity may determine a bandwidth required for the second terminal to transmit the video in real time by using the shooting parameter, select a communication link conforming to the bandwidth from the candidate communication links as a target communication link, and generate target communication link information indicating the target communication link. Thereafter, the executing entity may transmit the target communication link information to the at least one second terminal. In particular, the first terminal may determine a target communication link for video transmission with each of the second terminals. In this way, each second terminal can transmit the video to be synthesized to the first terminal in real time through the corresponding target communication link.
The candidate communication link here refers to a communication link that the first terminal is able to detect, for example a local area network or a general packet radio service technology network (such as a 3G, 4G or 5G network).
The realization modes can determine the bandwidth required by the real-time transmission of the video through the shooting parameters, so that the second terminal can transmit the video in real time, the first terminal can synthesize the panoramic video in time conveniently, and the generation efficiency of the panoramic video is improved.
In some optional application scenarios of these implementations, the selecting a communication link conforming to the bandwidth from the candidate communication links as the target communication link may include: transmitting a communication link information request to at least one second terminal; receiving available communication link information returned by at least one second terminal, wherein the available communication link information is used for indicating available communication links of the second terminals; for each of the at least one second terminal, the available communication links of the first terminal and the second terminal are selected from the candidate communication links, and the communication link conforming to the bandwidth is used as the target communication link.
In these optional application scenarios, the execution main body may send a communication link information request to each second terminal to request the second terminal to return available communication link information indicating an available communication link of the second terminal. Then, the execution main body may receive the available communication link information returned by each second terminal, and determine a target communication link with each second terminal according to its own available communication link.
In particular, the target communication link for the second terminal is not only an available communication link for the second terminal, but also an available communication link for the first terminal. In addition, the bandwidth of the target communication link is greater than or equal to a previously determined bandwidth required for real-time transmission.
