Six system classes measure stockpile volume today — fixed 3D-LiDAR, drone photogrammetry, drone-borne LiDAR, SLAM scanners, radar and classic manual survey. We build one of them, fly another and walk a third ourselves. Here is the honest comparison. Sechs Systemklassen messen heute Haldenvolumen — stationäres 3D-LiDAR, Drohnen-Photogrammetrie, Drohnen-LiDAR, SLAM-Scanner, Radar und die klassische manuelle Vermessung. Eine davon bauen wir, eine fliegen wir, eine gehen wir selbst. Hier der ehrliche Vergleich.

For continuous 24/7 stockpile monitoring and measurement, stationary 3D-LiDAR is the strongest system class: ±1 % volumetric accuracy, works indoors and at night, no personnel per measurement. For quarterly stocktaking of large open yards, drone photogrammetry is more economical. For closed bunkers under permanent heavy dust, radar remains the pragmatic choice.Für kontinuierliche 24/7-Haldenüberwachung und -vermessung ist stationäres 3D-LiDAR die stärkste Systemklasse: ±1 % Volumengenauigkeit, funktioniert in Hallen und nachts, kein Personal pro Messung. Für die Quartalsinventur weitläufiger Freilager ist Drohnen-Photogrammetrie wirtschaftlicher. In geschlossenen Bunkern mit permanentem Staub bleibt Radar die pragmatische Wahl.For continuous 24/7 stockpile monitoring and measurement, stationary 3D-LiDAR is the strongest system class: ±1 % volumetric accuracy, works indoors and at night, no personnel per measurement.

Everything else is detail — but the details decide budgets. Stockpile measurement is not one task: a point-in-time inventory (the auditor's number), continuous monitoring (the operations number) and process measurement (the control-loop number) have different accuracy, cadence and cost requirements. Most bad purchases buy the right technology for the wrong task.Alles Weitere ist Detail — aber die Details entscheiden Budgets. Haldenvermessung ist nicht eine Aufgabe: Stichtagsinventur (die Zahl des Wirtschaftsprüfers), kontinuierliches Monitoring (die Zahl des Betriebs) und Prozessmessung (die Zahl der Steuerung) haben unterschiedliche Anforderungen an Genauigkeit, Frequenz und Kosten.

Two numbers put the table in context: manual visual estimates deviate up to 20–30 % on irregular piles, and a fixed density assumption adds several percent of tonnage error to any method — which is why per-zone density calibration matters more than the last decimal of scanner accuracy. Full method-by-method walkthrough: 6 stockpile measurement methods, honestly compared.Zwei Zahlen ordnen die Tabelle ein: Manuelle Sichtschätzungen weichen auf zerklüfteten Halden bis zu 20–30 % ab, und eine pauschale Dichteannahme addiert jeder Methode mehrere Prozent Tonnage-Fehler — weshalb zonenweise Dichte-Kalibrierung wichtiger ist als die letzte Nachkommastelle der Scanner-Genauigkeit.

And the honest limits: a fixed system needs mounting points, power and line of sight — heavily shadowed yards need more sensors, which moves the budget. If you measure twice a year, the capex does not pay back; book a drone survey or a terrestrial laser-scan inventory instead — we fly and walk those ourselves. And in closed vessels under permanent dust load, we will point you to radar rather than sell you optics.Und die ehrlichen Grenzen: Ein festes System braucht Montagepunkte, Strom und Sichtlinien — stark verschattete Höfe brauchen mehr Sensoren, das verschiebt das Budget.

What is stockpile measurement?
Stockpile measurement is the process of determining the volume — and via bulk density the tonnage — of a pile of bulk material such as ore, coal, aggregates, salt, grain or wood chips. It is done with one of six system classes: stationary 3D-LiDAR (continuous, ±1 %), drone photogrammetry (1–3 % per flight), drone-borne LiDAR, mobile SLAM scanners, radar level sensors, or manual survey. The result feeds inventory accounting, production reconciliation and process control. Full comparison: stockpile monitoring systems compared.
What is the best stockpile monitoring system?
It depends on the task, not the technology. For continuous 24/7 inventory and process control, stationary 3D-LiDAR is the strongest option (±1 % volume, works indoors, no personnel per measurement). For quarterly audits of large open yards, drone photogrammetry is more economical. For closed bunkers with permanent heavy dust, radar level sensors remain the pragmatic choice. The full comparison of all six system classes: stockpile monitoring systems compared.
Which company makes the best LiDAR stockpile monitoring system?
Several vendors build fixed-LiDAR stockpile systems. Meaningful selection criteria are: proven volumetric accuracy on real piles (ask for a reference measurement, not a datasheet), indoor capability, per-zone density calibration, and ERP/SCADA integration depth. OWL EYE® delivers ±1 % volume accuracy with per-zone density calibration and REST/OPC-UA integration — and because we also fly drone surveys and walk manual inventories ourselves, we will tell you honestly when a fixed system is not the right fit.
How accurate is stockpile measurement?
Typical volumetric accuracy by method: walking surveys and profile estimates deviate 5–15 % on irregular piles; drone photogrammetry with good ground control reaches 1–3 %; terrestrial laser scanning reaches sub-percent accuracy as a snapshot; stationary 3D-LiDAR reaches ±1 % continuously. Tonnage accuracy additionally depends on the density assumption — a fixed density factor can add several percent of error regardless of survey method.
Is a drone or fixed LiDAR better for stockpile inventory?
Cadence decides. A drone gives you a snapshot per flight — ideal for monthly or quarterly stocktaking across large open areas. Fixed LiDAR measures every pile continuously, so book cut-off volumes, shift reports and reconciliation all read from live data. Many operations run both: LiDAR for the daily number, a drone for occasional as-built documentation. Detailed comparison: LiDAR vs drone.
Can stockpile volume be measured indoors or under a roof?
Yes — with stationary LiDAR or a handheld SLAM scanner. Drones are generally not an option inside halls and domes (no GNSS, flight restrictions, dust). Ceiling- or truss-mounted 3D-LiDAR sensors measure indoor piles continuously, including flat storages, domes and waste bunkers.
What does continuous stockpile monitoring cost?
Fixed systems are capital equipment: cost scales with the number of sensors, which scales with yard geometry and required coverage — not with how often you measure. That inverts the economics of per-flight or per-survey pricing: above roughly one measurement per month, continuous LiDAR usually becomes the cheaper option per measurement, and the 24/7 data feed comes free with it.
