Accurate stockpile measurement is essential for mining, construction, aggregate production, recycling, ports, and industrial operations. Inventory data influences production planning, financial reporting, material reconciliation, and operational efficiency. Traditional survey methods often require expensive equipment, trained surveyors, and significant field time. Modern mobile technology offers a practical alternative through AR-based stockpile measurement. Using a compatible smartphone or tablet, field teams can scan stockpiles, generate a 3D model, and calculate volume within minutes. This approach simplifies stockpile measurement while reducing time, improving safety, and supporting digital workflows. Mobile stockpile measurement enables organizations to capture measurements more frequently, maintain digital records, and make faster operational decisions. As businesses adopt digital transformation, AR-based stockpile measurement is becoming an accessible solution for accurate stockpile volume measurement and inventory management.
