  Collaborative robots are being increasingly utilized in industrial production
lines due to their efficiency and accuracy. However, the close proximity
between humans and robots can pose safety risks due to the robot's high-speed
movements and powerful forces. To address this, we developed a vision-based
safety monitoring system that creates a 3D reconstruction of the collaborative
scene. Our system records the human-robot interaction data in real-time and
reproduce their virtual replicas in a simulator for offline analysis. The
objective is to provide workers with a user-friendly visualization tool for
reviewing performance and diagnosing failures, thereby enhancing safety in
manufacturing settings.
