Teresterial laser scanner

The lab has a Trimble TX8 laser scanner (from 2014). The scanner is used to collect accurate measurements of the ground and the tree stems. Here is an example of one birch that is cut out from a multiscan (several scans are merged into one dataset):

A birch consisting of 12 million 3D-points. This tree was cut from a larger area scanned with a terresterial laser scanner (TLS).

The scanner is mounted on a tripod and collects 1 million points every second. In three minutes a full scan is done with a point spacing of about 4 mm on 10 meters distance.

Multiscan where a sphere is mounted on the previous and the next scan location for georeferencing.
Example from a forest plot in Remningstorp. The points are colored by altitude and intensity.
