We present an approach to laser range scanning in which quality metrics are used to automatically reduce the number of measurements acquired from a scanner viewpoint. As part of this approach we present improved versions of the orientation and reflectivity quality metrics, as well as introduce two quality metrics: resolvability and planarity.

Laser Scanning in Forests [PDF]
The introduction of Airborne Laser Scanning (ALS) to forests has been revolutionary during the last decade. This development was facilitated by combining earlier ranging lidar discoveries [1–5], with experience obtained from full-waveform ranging radar [6,7] to new airborne laser scanning systems which had components such as a GNSS receiver (Global ...
