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.

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. Die meisten Fehlkäufe kaufen die richtige Technik für die falsche Aufgabe.Everything else is detail — but the details decide budgets.

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.

| Jahresinventur (testierfähig) | Terrestrischer Laserscan | Sub-Prozent-Stichtag, von Prüfern anerkannt |
| Monatliches Management-Reporting | Drohnen-Photogrammetrie — oder LiDAR, falls schon installiert | günstigster ausreichender Stichtag pro Monat |
| Schichtgenaue Zahlen ins ERP/SCADA | Stationäres 3D-LiDAR | einzige Klasse mit kontinuierlichen, automatischen Daten |
| Abstimmung & Bandwaagen-Kontrolle | Stationäres 3D-LiDAR | entdeckt Drift in Tagen statt am Jahresende |
| Hallen, Kuppeln, Müllbunker | Stationäres LiDAR (kontinuierlich) oder SLAM (gelegentlich) | Drohnen können dort nicht fliegen |
| Großes Standort-Netz, quartalsweise gemessen | Drohnen-Programm | Capex für feste Sensorik lohnt unterhalb Monats-Frequenz nicht |
| Geschlossenes Silo, permanenter Schwerstaub | Radar | optische Systeme stoßen an ihre physikalische Grenze |
| Your task | Recommended system | Why |
|---|---|---|
| Annual audit inventory (auditor-signed) | Terrestrial laser scan | sub-percent snapshot, third-party recognised |
| Monthly management reporting | Drone photogrammetry — or fixed LiDAR if already installed | cheapest adequate snapshot per month |
| Shift-level numbers into ERP/SCADA | Fixed 3D-LiDAR | only class with continuous, automatic data |
| Reconciliation & belt-scale verification | Fixed 3D-LiDAR | catches drift in days instead of at year-end |
| Indoor domes, halls, waste bunkers | Fixed LiDAR (continuous) or SLAM (occasional) | drones cannot fly there |
| Large multi-site network, measured quarterly | Drone programme | capex for fixed sensors not justified below monthly cadence |
| Closed silo, permanent heavy dust | Radar | optics-based systems hit their physical limit |

The pattern behind the matrix: below roughly one measurement per month, mobile systems win on cost; above it, fixed LiDAR wins on cost and adds the continuous data layer that mobile systems structurally cannot deliver.Das Muster hinter der Matrix: Unterhalb von etwa einer Messung pro Monat gewinnen mobile Systeme bei den Kosten; darüber gewinnt stationäres LiDAR bei den Kosten und liefert die kontinuierliche Datenschicht, die mobile Systeme strukturell nicht liefern können.The pattern behind the matrix: below roughly one measurement per month, mobile systems win on cost; above it, fixed LiDAR wins on cost and adds the continuous data layer that mobile systems structurally cannot deliver.The pattern behind the matrix: below roughly one measurement per month, mobile systems win on cost; above it, fixed LiDAR wins on cost and adds the continuous data layer that mobile systems structurally cannot deliver.The pattern behind the matrix: below roughly one measurement per month, mobile systems win on cost; above it, fixed LiDAR wins on cost and adds the continuous data layer that mobile systems structurally cannot deliver.The pattern behind the matrix: below roughly one measurement per month, mobile systems win on cost; above it, fixed LiDAR wins on cost and adds the continuous data layer that mobile systems structurally cannot deliver.The pattern behind the matrix: below roughly one measurement per month, mobile systems win on cost; above it, fixed LiDAR wins on cost and adds the continuous data layer that mobile systems structurally cannot deliver.
OWL EYE® STOCKPILE is our stationary system: 3D-LiDAR sensors on roofs, masts or trusses, every pile measured continuously at ±1 %, per-zone density calibration, dashboards plus REST API and OPC UA into ERP/SCADA. It runs at 40+ European sites from salt mines to sugar campaigns — details at stockpile measurement & monitoring.OWL EYE® STOCKPILE ist unser stationäres System: 3D-LiDAR-Sensoren an Dächern, Masten oder Bindern, jede Halde kontinuierlich mit ±1 % gemessen, zonenweise Dichte-Kalibrierung, Dashboards plus REST-API und OPC UA ins ERP/SCADA. Es läuft an 40+ europäischen Standorten vom Salzbergwerk bis zur Rübenkampagne — Details unter Halden-Monitoring in Echtzeit.OWL EYE® STOCKPILE is our stationary system: 3D-LiDAR sensors on roofs, masts or trusses, every pile measured continuously at ±1 %, per-zone density calibration, dashboards plus REST API and OPC UA into ERP/SCADA.

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. Wer zweimal im Jahr misst, amortisiert den Capex nicht; dann buchen Sie besser eine Drohnenbefliegung oder eine terrestrische Laserscan-Inventur — beides fliegen bzw. laufen wir selbst. Und in geschlossenen Behältern unter Dauerstaub empfehlen wir Ihnen Radar, statt Ihnen Optik zu verkaufen.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.
