Drone-Based Volume Calculation & Stockpile Inventory Monitoring

Overview

Drone photogrammetry provides a fast, safe, and accurate way to measure the volumes of excavated materials, overburden, or stockpiles. By capturing aerial imagery and generating precise 3D surface models, AKSI drones deliver volumetric data within ±3% accuracy. This enables mine operators to monitor production, optimize material handling, and maintain up-to-date inventory records without halting operations or exposing staff to hazardous zones.
