Precise material management in various conditions

Time-of-flight laser technology offers reliable measurements of a variety of materials in a range of visibility conditions on a conveyor belt. This technology can also be used to monitoring conveyor belts for slippage and uneven loading. The Bulkscan LMS511 from SICK Automation uses time-of-flight laser technology to provide non-contact volume flow measurements on conveyor belts. […]

Surveying Africa’s largest uranium mine

Extra tight deadlines, harsh weather conditions and the biggest uranium mine in Africa – these were the project conditions that met Strydom and Associates in the Namib Desert. Using an unmanned aerial vehicle (UAV), the surveyors were able to conduct the needed volumetric measurement over a 15 km2 open pit mine in a single day. […]

Learning BIM on the job

We are “BIM-ready” is what I tell myself every morning when I arrive at work. However, the truth of the matter is, we are not BIM ready, we are not even “3D-ready”. So, how do we go about getting there? After months of going back and forth with the directors and staff, we at DSA […]

Automating photogrammetry with coded targets

This article looks at what coded targets are, when and why they are useful, how they compare with smart points, and provides examples of applications. Since its introduction during World War II, photogrammetric measurement has relied on humans manually identifying points in photographs and matching them to the same points in other photographs. The advent […]

Optimising stope design and quality monitoring with laser scanning

The demand of copper is such that progressively lower grades of copper ore are being mined profitably. One way to do so is by reducing the overall volume of waste material extracted, ensuring the highest concentration of the metal by minimising external dilution. Laser scanning can play a crucial role in achieving this. From a […]

Combining GNSS and sensor networks for construction efficiency

The construction industry faces a number of challenges. Performing under deadline pressure is just one example. More recently, the focus of attention is compliance with emission values. A geomatics approach could help. The European demolition industry, especially in Germany, must focus on compliance with strict regulations. In the last couple of years it has become […]
