Low Cost 3D Mapping Using a Commercial Drone/UAV: Application in Structural Geology

This presentation describes an experience of mapping a geological structure with a commercial UAV (Unmanned Aerial Vehicle).

Being based in Venezuela, an appropriate area for the acquisition was identified in the Andes Cordillera where a major strike slip fault (Boconó Fault) intersects geomorphic features modeled by the latest glaciation.

This fault is a major tectonic lineament oriented SW-NE, extending more than 300 km along the Venezuelan Andes and accommodating a dextral slip on the order of 1 cm/year.

This motion has displaced various landscape features that cross the fault, in particularly the "Los Zerpa" moraine system, located a few kilometers NE of the locality "Apartaderos".

The moraine formed during the last glaciation that ended 10,000 years ago; its northern tip crosses the Boconó Fault and is displaced 100 m towards the NE; this corresponds to a rate of 1 cm/year, which is consistent with GPS measurements.

Airbus: UAVs for aircrafts inspection

Airbus has demonstrated he benefits of using UAVs for aircraft visual inspection at the Farnborough International Airshow.

With this new method, the aircraft downtime for inspection is reduced to 10 to 15 minutes, instead of 2 hours using conventional methods.

The images catched up by the UAV cameras and especially those showing any potential non-quality such as scratches, dents and painting defects, are compiled in a 3D digital model, recorded in a database and then analysed. 

In addition, picture analysis can be done anytime afterwards and in an office, so the benefits of this innovative tool and process are significant: “The use of this new technology offers better working conditions including improving the safety and comfort for the quality inspectors”, says Nathalie Ducombeau, Airbus head of quality.
