Abstract
This contribution investigates correlations in terrestrial laser scanning on the scientific level. It summarizes recent approaches to model correlations, to develop measurement scenarios for the determination of correlations as well as to identify the influence of the correlations on estimation procedures. It can be concluded that the following challenges are remaining: complete synthetic modelling as well as the development of appropriate measurement scenarios to determine correlations in an empirical way. Additionally, the research has to be extended to the time domain, since deformation analysis implicitly needs to consider temporal correlations if they are existent. Therefore, the general ideas of modelling spatio-temporal correlations based on stochastic fields are presented. This will open the field for numerous possibilities to integrate modelled correlations into the deformation analysis process.
