The use of drones is becoming increasingly popular in the world of surveying. This is also the case with the Flick Engineering Association in Ibbenbüren, which has been using a Microdrones mdLiDAR1000 Classic since the beginning of 2020, among other tools to fly over roads, infrastructure, facilities, planning areas and in particular uav based survey of open pit mines and excavations and to collect precise data on them.

From an article by Microdrones.

“By using the mdLiDAR1000 Classic from Microdrones to measure, for example, dumps, gravel and sand excavations, open pit mines and quarries, we can not only increase the safety of all persons and staff involved, but also significantly increase the efficiency of the work processes,” explains Niels Flick from the Engineering Association on the use of the Microdrones survey equipment. “In addition, we can create the basis for an exact volume and mass calculation for documentation purposes and visualize through the 3D acquisition and document the areas overflown for a variety of applications. Precise variance analyses are also possible after two consecutive flights.”

Automation Through GPS Waypoint Mode

The mdLiDAR1000 Classic from Microdrones, used by the Flick Engineering Association, was specially developed for use in built-up areas and/or areas that are difficult-to-access and can be equipped with various sensors, each perfectly integrated into the drone. In addition, brushless electric motors are used to precisely compensate for the movements of the UAV and thus achieve the most stable recordings possible. “We can use it to reliably generate the accuracy we need,” relates Flick.

The aircraft, which weighs only 2.5 kilograms and can transport a maximum load of 1.2 kilograms, may also be fully controlled automatically during the flight using the GPS waypoint navigation system. “The drone then flies precisely to the GPS points that we are able to plan in the mdCockpit application. This enables us to precisely fly an exact flight route several times – for example, to identify changes in the landscape,” states Flick. “In addition, our employees no longer have to hike through impassable and dangerous terrain in order to be able to perform reliable measurements using ordinary methods.”

Overall, Flick is very satisfied with the Microdrones solution. “In terms of performance, the mdLiDAR1000 Classic is clearly a part of the high-end segment – which of course has its price. However, the comparatively high investment costs for drones, including sensors, have paid off for us, especially because of the quality of the recordings and the support we get from Microdrones,” Flick staunchly states.
