Research on Sports Live Broadcast System under Computer Big Data Technology

Based on the computer big data technology, this paper designs a system to realize the unattended live broadcast through the steps of video stitching, hot spot area determination, hot spot area tracking and so on. Then this paper designs the software and hardware environment of the system and determines the final implementation scheme and parameters through experiments. Secondly, this paper studies various related technologies involved in video stitching. In this paper, the concept of hot spot region is proposed and the detection algorithm of hot spot region is designed. The video splicing function is designed based on SURF feature point detection technology. After video fusion processing, the video Mosaic subsystem is finally realized. Finally, this paper designs the function and implementation of the video live relay subsystem. The simulation results show that this method can smoothly track the hot spots and extract them to realize real-time retransmission.
