Example two

Based on the 720 panoramic video projection system 10 provided in the first embodiment of the present application, the second embodiment of the present application provides another 720 panoramic video projection system 20, as shown in fig. 40, fig. 40 is a schematic structural diagram of another 720 panoramic video projection system 20 provided in the first embodiment of the present application.

The 720 panoramic video projection system 20 further comprises a memory 201, wherein the memory 201 comprises at least one disk storage array, and the memory 201 is used for storing video files received through the 5G base station 101.

In an application scenario of this embodiment, the 720 panoramic video file often occupies a large storage space, when the 5G cloud is used for projection and play directly, the phenomenon of unsmooth play or stuttering due to the limitation of the communication network speed is difficult to avoid, and the image playing effect is achieved.

Optionally, in an implementation manner of this embodiment, the memory is further provided with an expansion unit, and the expansion unit is configured to expand the disk storage array of the memory 201.

In an actual application scenario of this embodiment, for example, in some movie exhibition and sales, different 720 panoramic videos need to be continuously played in real time, and at this time, an expansion portion may be provided on the memory 201 to expand the storage array of the memory 201, and increase the storage space of the memory 201, so as to meet the current greater playing requirement of the 720 panoramic video projection system 20.

Optionally, in an implementation manner of this embodiment, the 720 panoramic video projection system includes at least one conversion device; the conversion device is used for converting the non-720 panoramic capsule screen video file stored in the memory 201 into a 720 panoramic capsule screen video file based on a UV conversion relation and sending the converted 720 panoramic capsule screen video file to the processor; the processor is further used for sending a video uploading request to the 5G cloud based on the 5G base station, and uploading the obtained 720 panoramic capsule curtain video file to the 5G cloud based on the 5G base station. The processor may be further configured to store the converted 720 panoramic capsule video file in the memory 201.

Optionally, in an implementation manner of this embodiment, the type of the non-720 panoramic capsule screen video file includes at least one of a 2D video file suitable for a two-dimensional screen, a 3D video file suitable for a two-dimensional screen, or a dome video file suitable for dome playing.

Correspondingly, the processor 104 is further configured to select a UV conversion relationship matched with the type of the non-720 panoramic capsule screen video file from a plurality of preset UV conversion relationships according to the type of the non-720 panoramic capsule screen video file; and the video processing unit is used for carrying out UV conversion on the image of the non-720 panoramic capsule screen video file based on the selected UV conversion relation to obtain a video frame image adapted to the 720 panoramic capsule screen 102.

Specifically, the present embodiment exemplifies different types of video files:

the video frame image resolution of a 2D video file suitable for a two-dimensional screen is generally: the resolution is 720/704/640 × 480i60(NTSC) or 768/720 × 576i50(PAL/SECAM), and 1920 × 1080p60, i.e. 1920 pixels per horizontal scanning line, 1080 scanning lines per picture, etc.;

the resolution of 3D video is expressed in volume (translated into "voxel" in chinese). E.g., a resolution of 512 x 512 voxels for simple 3D video, etc.;

a dome video, such as a dome movie, also called a dome movie or a dome movie, is a large screen movie appearing in the 70 th 20 th century. The shooting and the showing both adopt ultra-wide angle fisheye lenses, the display screen of the camera is hemispherical, and the audience is surrounded by video files in the display screen when watching videos.

In an application scenario of this embodiment, because the video volume of the 720 panoramic capsule screen video file is relatively small, most of the mainstream videos in the current market are a 2D video file suitable for a two-dimensional screen, a 3D video file suitable for a two-dimensional screen, a dome screen video file suitable for dome screen playing, and the like, and the projection effect of directly projecting these videos onto the 720 panoramic capsule type screen provided by this application is poor, and a better viewing immersion feeling cannot be provided for viewers. In this embodiment, in order to improve the projection effect of the videos, the type of the non-720 panoramic capsule screen video file is identified, and the processor selects a preset UV conversion relationship matched with the type of the file to convert the non-720 panoramic capsule screen video file into the 720 panoramic capsule screen video file, so that the 720 panoramic video projection system of this embodiment can be used for projecting the non-720 panoramic capsule screen video file.

Optionally, in an implementation manner of this embodiment, the processor is further configured to encrypt the video file uploaded to the 5G cloud, and decrypt the video file acquired from the 5G cloud.
