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

Point cloud and slot schematic 1
  • 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.

"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

  1. Q: Is LiDAR reliable in dust? — A: VMS-W ships with IP65 shrouds and positive-pressure filtration; stable above PM2.5 ~500 μg/m³.
  2. Q: ERP integration? — A: APIs support SAP, Oracle, and similar ERPs with daily stock sync.
