Steps S102 to S106 are the same as those in the first embodiment of the present invention, and are not described herein again.
Specifically, for each of a plurality of panoramic videos shot in advance, a plurality of high-definition panoramic pictures are shot as a panoramic picture set corresponding to the panoramic video while the videos are shot, after a user sends a shooting instruction, the cloud first obtains panoramic pictures in the panoramic picture set corresponding to the panoramic videos according to time information, and then obtains partial pictures, namely shooting pictures, of corresponding visual angles from the panoramic pictures according to visual angle information and sends the partial pictures to the mobile terminal.
As an example, it is assumed that a panoramic video a1 shot in advance has 24 video frame images, and the corresponding panoramic image set is Ap1, and the first corresponding case is that the panoramic image set Ap1 also has 24 high-definition panoramic images in one-to-one correspondence with the video frames of the panoramic video a 1; or, the second corresponding case is that the panoramic image set Ap1 has 2 high-definition panoramic images Ap11 and Ap12 corresponding to the video frames of the panoramic video a1, where Ap11 corresponds to the first 12 video frame images of the panoramic video a1, and Ap12 corresponds to the last 12 video frame images of the panoramic video a 1;
after a user sends a photographing instruction, the cloud first determines (assumes) that the frame 12 is a panoramic video frame image according to the time information, and then determines that the corresponding high-definition panoramic image is a12 th panoramic image (the first corresponding situation) or a panoramic image Ap11 (the second corresponding situation) in the panoramic image set Ap1, and then acquires a partial image of a corresponding view angle according to the view angle information on the 12 th panoramic image (the first corresponding situation) or the panoramic image Ap11 (the second corresponding situation) in the panoramic image set Ap1, so as to obtain a photographed image.
It should be noted that the above is merely an example, and the corresponding manner of the panoramic video and the panoramic image set is not limited to the example.
Therefore, the user can not only realize the interaction with the display equipment, but also obtain a higher-definition picture for taking a picture, so that better triple experiences of watching, operating and taking a picture are obtained.
According to the third embodiment of the present invention, in step S101, a material library B is simultaneously established at a local server, where the material library B includes one or more panoramic videos.
The panoramic videos in the material library B and the material library A are the same video file which is in one-to-one correspondence, and the content and the video resolution are the same, or different video files which are in one-to-one correspondence, the content is the same, and the video resolution is different, wherein the resolution of the panoramic video in the material library A is lower than that of the panoramic video in the material library B.
In step S102, playing the panoramic video on the display device includes acquiring the panoramic video from the local server by the first playing module, generating a playlist, decoding the panoramic video according to the playlist order, and playing the decoded panoramic video.
Steps S103 to S107 are the same as those of the first and second embodiments of the present invention, and are not described herein again.
As AN example, N panoramic videos shot in advance are stored in the cloud, including panoramic videos a1, a2, A3, … …, AN; and stored at the local server, including panoramic videos B1, B2, B3, … …, BN.
The panoramic video is large in capacity, large in occupied storage space and large in occupied bandwidth in transmission compared with a common video, so that the panoramic video is set to be stored in advance at a local server, and bandwidth limitation and flow limitation caused by the fact that a cloud end needs to send large-capacity data to display equipment in real time are avoided (if the panoramic video is only stored at the cloud end, when a user needs to interact with the display equipment through a mobile terminal, the cloud end needs to transmit the panoramic video to the display equipment and the mobile terminal through a network at the same time, and video streaming is blocked or delayed due to the transmission of the large-capacity data).
As another example, N panoramic videos shot in advance are stored in the local server, including panoramic videos B1, B2, B3, … …, BN; and simultaneously, carrying out recompression coding on the N panoramic videos shot in advance to obtain the N panoramic videos with lower video resolution, and storing the N panoramic videos in the cloud, wherein the N panoramic videos comprise panoramic videos A1, A2, A3, … … and AN.
The reason is that the limitation of the screen resolution of the mobile terminal device enables a user not to watch the high-resolution panoramic video through the mobile terminal, so that the video file with lower video resolution can be stored in the cloud, the storage pressure of the cloud can be reduced, and the requirement that the user watches the high-resolution panoramic video through the display device can be further met.
