Lead manufacturer: Heguang Cloud warehouse volumetry for precise inventory monitoring
Accurate warehouse volumetric measurement and real-time monitoring with 3D vision
Pain points
How manual measurement drags down lead manufacturing efficiency
A global lead producer managing carbon-based materials and lead-bearing scrap faced two long-standing issues:
- **Slow manual surveys:** area × height guesses took over four hours per pass with about 30% error;
- **No live picture:** bulk piles across warehouses left production and purchasing blind to real-time stock.
HEGANG YUNCHANG VMS-W warehouse volumetry in three steps
After site survey, HEGANG YUNCHANG engineers deployed the VMS-W intelligent warehouse volumetry system with three modules:
1. Intelligent zone planning
- Dynamic zoning down to 0.1 m² for irregular piles;
- Setup time from about two hours to about ten minutes for most industrial warehouses.
2. Point cloud + image fusion
- Aligned LiDAR (about ±2 cm) with 4K industrial video for textured 3D models;
- Web/mobile views with density heatmaps—abnormal pile-ups flagged sooner.
3. AI pile recognition engine
- Deep learning separates people, trucks, and eight object classes (>97% accuracy in training conditions);
- Tagging for audit-friendly inventory objects.
Quantified results
| Metric | Before | After | Improvement |
|---|---|---|---|
| Time per measurement | 4.2 hours | 0 hours (fully automatic) | 100% automated |
| Volume measurement error rate | 30% | ≤2% | ~15× accuracy gain |
| Annual labor cost | CNY 156,000 (two dedicated staff) | CNY 0 (no dedicated staff) | Full savings |
| Inventory turnover | 3.2×/year | 5.8×/year | +81% |
"HEGANG YUNCHANG's volumetry stack changed how we run warehouses. We log in and see every dome in real time—even forecast next week’s consumption. Emergency buys dropped about 20%." — supply chain director
FAQ
- Q: Is LiDAR reliable in dust? — A: VMS-W ships with IP65 shrouds and positive-pressure filtration; stable above PM2.5 ~500 μg/m³.
- Q: ERP integration? — A: APIs support SAP, Oracle, and similar ERPs with daily stock sync.
