PAYLOADS FOR spatial DATA CAPTURE
When mounted on a drone, LiDAR systems offer huge potential for spatial mapping. Like photogrammetry, LiDAR captures information in a manner that allows for accurate measurements, but the active technology boasts faster processing and can achieve a higher level of detail.
NEXTCORE RN50
The NextCore RN50 LiDAR is an active technology — distance calculation is performed instantly by the sensor. This means point clouds are available within minutes rather than hours after landing. LiDAR also needs only one return from a surface to make it present in the point cloud. As a result, it is very effective at penetrating even the densest of canopy coverage. We’ve found that small objects, such as powerlines, are also very accurately represented. The cloud-based processing makes producing quality, in-the-field results quick and easy. Where good lighting is essential for photogrammetry, LiDAR provides its own light source through a laser, meaning that data can be collected in low light situations.
When mounted to a DJI Matrice 600, capturing data with the NextCore RN50 is a simple on-off operation. Once landed, the data is post-processed in the cloud with results provided far more quickly than traditional software. The only additional requirement is RINEX base station data, either from an on-site base or CORS data from a nearby reference station.
The unit creates 420’000 shots per minute with up to three returns per shot, allowing up to 1.26 million points per second to be recorded. The laser range is up to 150m @ 80% reflectivity, and laser ranging error is 30mm RMS. At an altitude of 50m, absolute accuracy is up to 50mm.
