Participants:
This project is about merging two or more
laser scanning point clouds. When point

clouds are merged they are usually only
merged two at the time. This can result in

gap, when many point clouds are merged.
The project describes how it, by the means
of anblok is possible, to carry out one

merging, where the adjustment contains all
observations.
In the project an experiment is carried out.
The experiment is to merge three point

clouds by the means of an anblok program
made by the project group.
Nadja Sarah Kabkizan
Calculations of the influence on the merging
by different conditions are made before
the three point clouds are gathered.

The calculations are made in Testnet,
where confidence ellipses for the points are
calculated in different situations, where the
geometry in between the points and the
number of redundants, is changed.
Finally an evaluation, on how well the
