The challenge
Activities at a scrap-remelting furnace (loading, skimming, stirring) and every door opening were logged by a person watching video and typing times into Excel. The method was slow, could not run 24/7, and events were missed. Every door opening means heat loss.
Our approach
- Validate on historical recordings: detect door states every second from the existing camera.
- Monitor doors live, with indicators and alerts when a door stays open without an activity.
- Recognise activities with object tracking and activity models, including parallel activities.
- Generate the Gantt timeline and Excel export the team already uses, with a video clip for every event.
Results & features
- In one historical recording, video analysis found a 2 min 17 s door-open event that was missing from the manual log.
- Each event can be verified against its own video clip.
- Processing runs inside the factory, with a future link to the energy management platform.
