UAV Image Processing

TreisTek does automated post-processing of the UAV flight data for DTM and true orthophoto production. Automatic triangulation based on several point detection and matching techniques with automated blunder detection, bundle block adjustment is achieved.

UAV Image Processing

With a mini-UAV (Unmanned Airborne Vehicle) a trace or fully opaque area can be overflown and photographed. The digital images have a ground resolution between 3 and 30 cm, depending on the altitude. The position and orientation of each photo are recorded.

Ortho Mosaic: a coverage area in map projection
DEM (Digital Elevation Model): a 3D display of terrain elevation
Both products can be combined to form a photo-realistic 3D display of the recorded area

Asset & Plant Inspections

TreisTek's unique UAV data processing services are designed for inspecting hazardous and difficult to access assets and structures.

Cooling towers
Bridges (from above and below)
Utilities / powerlines
Chemical plants and refineries
Industrial roof inspections
Offshore activities (oil & gas platforms and pipelines)
Mining infrastructure
Wind turbines
Weather & communication towers
Remote sensing (gas, lasers, magnetometers)

Engineering & Construction

The benefit of using UAVs for power line inspection work is that they're able to fly into the middle of fields to inspect pylons which are several hundred metres high - where accessibility for cranes is just not possible. Similarly, some of the assets we inspect are in highly forested locations that are too dangerous for full-size helicopters to approach.

Mining & Resources

We deliver a diverse range of services to many resources companies. Our solutions are seen as an ideal tool for mine surveying because we operate from the perimeter of busy, working pits.

Our services include:

Stockpile calculations
Open cut pit volumes
Pit wall inspections
Photogrammetric Applications
Point cloud generation
Geo-referenced ortho-mosaics
Thermographic surveys
Multispectral imagery
Environmental monitoring
Heritage area reporting

Thermographic Imaging

Thermographic imagery processing services are offered to our mining, emergency services and utility clients.

We can identify forest and mine fires which are not visible to naked eye using thermal imagery processing obtained from UAV. Thermal images also generate DTM.
