Based on the interactive multi-dimensional experience system of ice and snow sports, the project studies 3D reconstruction, multi-camera position planning, viewpoint prediction, and special effects generation, especially the audio-visual language design of the VR panorama program. Aiming at the hot events of the Winter Olympics, the VR live broadcasting scheme and the 3D digital twin environment of the venues of the Winter Olympics are designed. The VR panoramic live broadcasting system with a clearer and more comprehensive experience is used to create the unique charm of hockey games by focusing on "new perspective", "intelligent camera tracking", key shots of hockey, and atmosphere shots. Based on the digital twin of the Winter Olympic Games, personalized deployment of dynamic objects, high realistic simulation of multiple cameras, rapid stitching of multiple cameras, creative VR content generation and other functions are realized to complete the correction feedback and realistic deduction of creative design.
VR language creative design and twin deduction have universal value and can be applied to other competitive sports events including ice and snow sports. After simple extension design, the system can be applied to the VR live broadcast of artistic performances and other activities, which has practical meaning for promoting cultural and sports activities.
