Movable Dynamic Data Detection and Visualization for Digital Twin City

A digital twin city can simulate urban phenomena or designs based on the digital model similar to a real city. To build a digital twin model of a city, it requires static data such as terrain, buildings, roads and dynamic data such as weather, temperature, humidity. The moving objects such as vehicles, pedestrians can be reproduced with the movable dynamic data which has 3D position, direction and time. In this paper, we propose a platform which has movable dynamic data detection, reconstruction, and visualization steps. The proposed platform can visualize the past urban appearance and road situations in 3D model at the time and space desired by the user.
