Abstract
This Panoramic video is a kind of video which is produced by splicing and fusion after 360 degrees omnidirectional shooting with multi-eye fisheye lens. Compared with ordinary video, panoramic video has broader vision, richer perspective and is not limited by space and region. Nowadays, panoramic video has been widely used in video surveillance, live video broadcasting, video conferencing and other fields. However, due to the large amount of panoramic video data, the bandwidth requirement in real-time transmission process is very high, and the problem of delay and packet loss is easy to occur. Considering that users are only interested in local areas when viewing panoramic videos, this paper designs and implements a panoramic live broadcast system based on spherical distribution. Compared with the traditional live video broadcasting system, the system maps the panoramic video on the server side and intercepts the local texture distribution. In the process of distribution, two-way information interaction between the server and the client is needed. The user drags the client screen to select the perspective he wants to see. The client sends the coordinates of the perspective to the server. The server intercepts the spherical texture and sends it according to the request coordinates. The results show that the live video client can see high-definition, distortion-free panoramic video in real time, and can freely switch different perspectives to watch panoramic video, which has a good experience effect.
