During the registration and georeferencing of terrestrial laser scans, it is common to use
targets to mark discrete points. To improve the accuracy of the registration, the uncertainties …

The target-based point cloud registration and calibration of terrestrial laser scanners (TLSs)
are mathematically modeled and solved by the least-squares adjustment. However, usual …

Depending on the size, shape, and gray intensity distribution of charge-coupled device
(CCD) imaging retro-reflective targets (RRTs) in close-range photogrammetry, and based on …

The coordinate determination of the rotation center of a space TT&C (Telemetry, Tracking
