Stockpile Volumetric Measurement

Bureau Stephan is transforming Stockpile Volumetric Measurement

Offering world-class solutions for industrial stockpile assessment:
- Safe
- Efficient
- Accurate
- Cost-Effective

Traditional techniques for estimating stockpile volumes are complicated, time consuming, costly and often inaccurate. Bureau Stephan UAV's are able to rapidly capture stereo imagery of stockpile lots.
Bureau Stephan UAV's are able to rapidly capture stereo imagery of stockpile lots and their surroundings without the labor inefficiencies and safety issues normally associated with traditional volumetric surveys.
This imagery is processed into a dense point cloud using Bureau Stephan's alogorithms and photogrammetric software, generating a 3D map that may then be compared to previously existing stockpile data.
Efficient and cost-effective, this technology is being used by Bureau Stephan's customers around the world to accurately calculate variations in stockpile volumes over a given time period.
