The mdLiDAR1000HR aaS is the next generation of industry leading drone Lidar precision survey equipment offered by Microdrones. The mdLiDAR1000HR aaS uses the lifting power, resilience, and efficiency of the Microdrones aircraft platform to carry a perfectly integrated Velodyne VLP-16 PUCK LiDAR sensor for increased coverage and the ability to deliver high-resolution point clouds.

From Microdrones.

“The Microdrones mdLiDAR1000HR aaS precision was analyzed by flights between 30 and 60 meters over a wide sample of surfaces (asphalt, gravel, roofs, natural ground) exhibiting different reflectance,” said Dr. Nicolas Seube, mdInfinity Chief Scientist Director R&D. “mdLidar1000HR aaS with a 90 degree field of view for both scanned points and imagery, repeatedly provides a precision of 1.6 cm (.052 ft) at 1-σ when flown at 40 m (130 ft) at a speed of 8 m/s (18 mph). This was confirmed by a repeatability analysis.”

To demonstrate the high-resolution point clouds that can be created from data collected by the mdLiDAR1000HR aaS, Microdrones has provided a dataset complete with some dense forest coverage along with a power line corridor. These point clouds demonstrate the vegetation penetration capabilities and the ability to provide ground classified data with mdInfinity. CLICK HERE to open the viewer.

The Workflow

Each project was conducted using the Microdrones workflow of Plan, Fly, Process and Visualize. Mission and flight preparation details, as well as the flight parameters and data acquisition will be reviewed for each flight.

Plan & Fly

Flight planning begins in mdCockpit and is then verified in the field upon closer inspection of the project. When flight planning is complete, the mission can then begin and the user can choose to autonomously fly the project.

The Data was collected in 1 flight of the mdLiDAR1000HR, flying a grid above the Forest at a constant flight altitude of 60 meters at a speed of 5 meters per second with 60% sidelap. The particular mission was planned with a grid pattern to ensure the needed resolution was captured to detail the individual trees.

To capture the data over the powerline corridor, the mdLiDAR1000HR flew at a height of 40 meters at a speed of 5 meters per second with 60% sidelap. By planning a flightpath parallel to the utility line, the 16 layers of data collected VLP-16 do a great job of capturing the small detail of the overhead utilities.
