Message-passing framework for multi-camera worker tracking in construction

Abstract
En 中文
• Addressed multi-camera tracking challenges in construction: similar attire, occlusion, and view transitions causing ID switches. • Proposed system using region-based re-ID for better features in occluded/similar-gear workers and message-passing for association. • Integrated detection per camera with localization, features, and motion for effective clustering and track generation. • Achieved IDF1 of 68.30 (controlled) and 85.10 (outdoor), MOTA 79.7/79.2, plus strong CAMPUS benchmark results. • Enables robust safety/productivity monitoring for construction sites, inspiring future occluded multi-view applications.
