Photogrammetry and 3-D modelling
Photogrammetry is generally defined as the process of deriving metric information on an object through measurements made on photos that represent it. Modern Photogrammetry has a wider domain, which includes the use of both passive and active images (thermal images, radar etc ...). The potential applications of Photogrammetry are practically infinite: engineering applications of photogrammetric techniques are for example: aerial images, orthophotos, maps and 3D models.
For Tunnels During Construction
LRRT uses the digital photogrammetry technique to create three-dimensional models of the soil or rock exposed by the excavation, of the sprayed concrete and of the lining surface of the tunnels.
For Tunnels in Operation
The relief of the intrados of the final cladding can be carried out with an accuracy of 1 mm, which can be modified according to the needs of the Client.
For Excavations, Slopes, Quarries
LRRT uses digital photogrammetry to create three-dimensional models of natural or man-made slopes, such as excavations, trenches, quarries, large foundations, aggregates and mining dams.
Inspections of Dams, Rockfall Defence Systems, Wind Turbines
LRRT uses digital photogrammetry to create three-dimensional models of natural or man-made slopes, such as excavations, trenches, quarries, large foundations, aggregates and mining dams.
