The Trakblaze TVS (Truck Volume Scanner) – scans volumetric loads of mining dump trucks by driving slowly below an elevated ‘Scan Head’. This is essentially a mounting platform for two scanning laser range-finders, which are referred to as laser scanners. When a dump truck crosses the scanned area below the Scan Head it falls within the field of view of these laser scanners which perform thousands of distance measurements per second.
The speed of the software platform enables for fast calculation and transportation of real time feedback and key metrics, to optimise loading of each and every mining dump truck. In turn, this assists operators in the fine tuning of loading operations, and it provides near real-time output.
A vehicle is initially scanned empty and recorded into the system database as an empty vehicle profile (zero reference). Load volume is computed on subsequent scans by comparing each new loaded vehicle profile against the recorded empty profile. This involves aligning the empty and loaded vehicle profiles spatially in software and computing a load profile from the difference between them.
