Original Abstract Submitted
This method estimates 3D trajectories of observed individuals in a 3D world coordinate system, using RGB videos captured by cameras and associated camera parameters. The process involves an online segmentation of video streams using sliding windows during the video capture phase. Within each window, head bounding boxes are detected from each frame of videos. Multiple Object Tracking is employed on each camera view to associate these bounding boxes into 2D tracklets. A cross-view association is implemented to consolidate identical person's 2D tracklets from different views into a unified cluster. Triangulation geometry is applied to each cluster, resulting in the generation of 3D tracklets for each individual. The Euclidean distance between short-term 3D tracklets of adjacent sliding windows is calculated, facilitating the connection of these short-term 3D tracklets into long-term 3D tracklets. This methodology offers a comprehensive and efficient approach to tracking individuals in a 3D space using multi-camera RGB videos.
