PointReg
PointReg is a one of a kind, powerful software to perform global registration and georeferencing of point cloud data through a rigorous least squares adjustment. It was primarily developed for terrestrial laser scans but can incorporate other forms of point cloud data. PointReg has the following features:
- Performs a fine tuning of the registration of laser scans based on the results from an initial coarse registration.
- Performs efficient batch processing of refined cloud to cloud matches for large quantities of scans. Automatically determines overlapping scans for matching. (Requires an initial alignment to be completed first in other software).
- Can be used to perform strip adjustments of UAS or airborne lidar flight segments.
- Performs rigorous, global least squares adjustments using cloud to cloud pairwise matches, targets, total station measurements, and GNSS coordinates obtained for control points.
- Provides registration results in a transparent manner for simplified error checking.
- Reports registration quality statistics for each scan. Performs a comprehensive statistical analysis of registration errors between overlapping scans.
- Reports detailed least squares adjustment results for each measurement observation and flags observations with higher than expected errors.
- Contains tools to identify potentially misnamed targets.
- Corrects GNSS coordinates co-acquired at each scan position for out of level setups.
- Contains tools to estimate the scan origin coordinates and azimuth of a scan based on an initial cloud to cloud registration in a local coordinate system.
- Includes tools to facilitate import/export of georeferencing information from several leading point cloud processing softwares including Maptek PointStudio, Leica Cyclone, and Riegl Riscan Pro.
- Handles large collections of scans with ease and implements parallel processing for efficiency.
- Applies georeferencing transformation to LAS/LAZ files in batch mode.
NOTES: PointReg focuses on the fine tuning of the registration, and as such, requires an initial, coarse registration of scan data to be completed. PointReg will apply leveling based on sensor readings but it will not adjust the leveling of the scan.
