Abstract

Deformation is typically estimated by comparing scans of terrestrial laser scanner (TLS) over the same area but at different time instants. However, such a method can only estimate the difference between two successive surveys, which may be caused by instrumental error and registration error instead of the real deformation, affecting the reliability of deformation monitoring. In order to improve the reliability of TLS-based deformation monitoring, it is necessary to estimate the errors in TLS measurements and determine the precursory displacements that can be detected. In this paper, the error entropy model is exploited for inspecting the threshold value in deformation monitoring, i.e. the minimum detectable deformation magnitude of a TLS. The experimental results demonstrate that deformation greater than the threshold calculated by the proposed error entropy based method can be reliably detected.
