The LiDAR drone is essential on the geomatics market!

The LiDAR drone is becoming the key solution for measurement professionals. Indeed, surveyors and topographers are increasingly demanding in terms of performance and accuracy. Therefore, it becomes necessary to respond to their needs by following market trends and innovation challenges. Discover the advantages of the LiDAR drone to map a 3D scene with direct georeferencing.

Hélicéo develops an innovative LiDAR drone

Hélicéo offers a range to cover all geomatics professions and meets all needs. It consists of aerial photogrammetric drones, but also terrestrial and bathymetric solutions. Recently, the LiDAR RTK POD was born. Internally, an R & D team composed of expert geomatics and aeronautical electronics engineers remains on the alert to anticipate all innovations and adapt them to products.

The SuperFox6 LiDAR RTK

Indeed, the company has developed the LiDAR technology associated with the Drone Box RTK and the HASK processing software. This guarantees geo-positioning of the laser point cloud with an accuracy of 3 cm. Hélicéo took the opportunity to create its new multi rotor drone: the SuperFox6. This one is compatible with the LiDAR POD, but also with photogrammetry. It offers a record autonomy of up to 43 minutes. It should be noted that the SuperFox6 takes the legendary qualities of its predecessor with a wind resistance of over 55 Km / h. Moreover, this drone LiDAR has a mission capacity of 5000 m of altitude, as experienced at the beginning of 2018 in the Cordillera of the Andes, region where the mines and quarries in altitude are numerous.

This drone LiDAR is useful in many applications: mines and quarries, roads and railways, infrastructure and power line inspection or precision agriculture. At the end of the mission, the Trimble Real Works software process the point cloud.

 

Lasergrammetry becomes a privileged topographic survey mode

Topography world is today strongly impacted by technological developments such as lasergrammetry. This 3D rendering mode offers new perspectives of results compared to photogrammetry. First, it saves a lot of time since it eliminates the post-processing time that could last several days. Then, it gives the possibility of considerably increasing the precision and proves to be very effective for scanning large scenes with complex geometries. Lasergrammetry works using a scanning rangefinder device known as LiDAR (Light detection and Ranging). This calculates and exploits the distances and angles by measuring the time elapsed between the emission and the receipt of a laser wave. Its particularity is that it can cross and classify the vegetation to reach the ground, but also to raise the wired networks and the smooth surfaces.
