Videos in this page demonstrate the i4D reconstruction process for outdoor scenes with multiple walking pedestrians. The Lidar monitors the scene from a fixed position and provides a dynamic point cloud. This information is processed to build a 3D model of the environment and detect and track the pedestrians. Each of them is represented by a point cluster and a trajectory. A moving cluster is then substituted by a detailed 4D model created in the studio. The output is a geometrically reconstructed and textured scene with avatars that follow in real time the trajectories of the pedestrians. (Press on the images to view the demo videos).
