This speech will introduce a cutting-edge technology that enables the creation of a live, 3D photorealistic Metaverse using AI, 3D modeling, and panoramic image stitching technologies. A photorealistic digital twin is a virtual replica of a physical object or space, created using 3D modeling, panoramic image stitching, and AI technologies. Some of the areas where photorealistic digital twins can have a significant impact is in smart factories and cities. By creating a digital twin of a factory or a city, we can visually simulate and optimize various processes, reducing costs and improving efficiency. One specific application in a smart factory is virtual patrolling. To create a virtual environment where personnel can patrol and control the factory remotely, we can reduce the need for on-site activities, Further examining this application, we can better understand the potential of a photorealistic digital twin in the Metaverse, and the role it will play in shaping the future of virtual but immersive experiences. Overall, this speech will demonstrate how AI, 3D modeling and panoramic image stitching technologies can be combined to create a LIVE 3D photorealistic Metaverse world, and its potential applications in various areas.
