Fast, accurate, drone-based scans without GCPs
Emesent Aura now supports RTK, automating high accuracy georeferencing and drift correction for Hovermap scans on DJI’s M300 and M350 drones. This enables the delivery of fast, accurate and precise above-ground drone scans on demand, without the need to lay out and georeference ground control points.
Simply attach the Hovermap to your DJI M300 or M350 drone with the purpose-built mount, establish a connection and you are ready to start scanning. During processing Aura automatically evaluates the GPS signal quality and will intelligently choose the optimal combination of RTK and SLAM (either RTK and SLAM, or SLAM only if RTK is not of high enough quality), toggling between the two, to provide the user with the most reliable and robust point cloud.
“We have done flights at 100m with 40% overlap, captured at 6m/s and generated data with check points around the +-20mm range. We sit back and are astonished by the data.”
– David Wallingford, Talison Lithium

Case study
Drone RTK: Improved SLAM accuracy & georeferencing report
Utilizing RTK capability can improve SLAM performance in low-feature areas and/or long-duration scans as well as georeferencing the point cloud.
It also can enable Hovermap to produce high-quality point clouds when traveling at higher velocities and altitudes and mitigate the trade-off between low resolution and SLAM accuracy.
