Stockpile volume measurement can be accomplished with higher accuracy using 3D scanning methods. Stockpiles are scanned for a variety of reasons, mainly to determine the pile volume for monthy, quartery or annual inventory auditing. Our 3D scanning method has an advantage over handheld laser methods in that the true geometry of the pile is considered. For example, this pile is really one large pile with one or two “child” piles attached to it:
We incorporate both 3D laser scanners as well as drone/UAV based aerial image capture. With either aerial or terrestrial 3D scanning, the pile need not be perfectly formed or be on a flat surface to incorporate the attached material and accurately calculate the volume. Aerial scanning has the additional advantage of being able to see craters or pits in the center of the pile, which are sometimes not visible from the ground.
It may be challenging for traditional stockpile surveyors to get accurate and safe measurements of your piles. Our technology allows us to take both extremely accurate and extremely safe measurements of your piles. Our laser scanners and drones/UAVs can measure piles at a safe distance.
How does stockpile volume measurement work?
In the field we utilize a truck-mounted 3D scanner to take scans at multiple positions around each pile. Back in the office, we combine the scans together to create an accurate 3D point cloud of the pile from which the material volume can be calculated.
What types of materials can stockpile volume measurement be performed with?
Coal, gypsum, bottom ash, bauxite and many more quarry or cement related items
Grains, sugar and other agricultural products
Ores from mining operations including gold, silver or iron ore
Wood chips and pellets
Any other bulk material stored in open piles
Can closed piles be measured, such as those in a barn, silo, dome or shed?
Yes. Our terrestrial 3D laser scanners are great for capturing indoor piles.
How long does the process take?
Depending on whether aerial or terrestrial 3D scanning is used, as well as how large and complex the piles are, we can typically capture 15-20 piles in a single day. Depending on their size and circumstances, it is potentially possible to capture many more using aerial scanning.
What is the cost?
Costs range from under $1000 to a few thousand or more, depending on number and sizes of piles.
