This study developed a 3D match reconstruction and immersive data analysis system for boxing broadcast videos. By combining 3D human pose and global position estimation technologies, along with interactive editing tools, the system accurately converts match footage into 3D reconstruction models. Users can view the match in an immersive environment, observing detailed movements from different angles. Additionally, the system integrates various visualization analysis tools within the 3D space, helping users deeply analyze the match process and understand the athletes' tactical intentions and strategies.
