A Novel Method for the Visualization of Deformation Data
Alexander Reiterer, Peter Rautek, Eduard M. Groller · 2010
SUMMARY Modern deformation monitoring systems, such as laser scanner or image based tacheometer are producing a vast number of object points. One of the main problems concerning the analysis and interpretation of high density deformation measurements is the visualization of the data respectively of the underlying deformation. Most existing geodetic deformation visualization techniques are based on plotted displacement vectors or on a colour coded representation. A visualization of displacement vectors is unsuitable for high density point clouds; colour coded representation is more apprporiated with some limitions regarding the interpretation (e.g. direction of movements or deformations can represented restriced only). In this paper a novel technique for the visualization of deformation data is presented – we call this technique exaggerated visualization. The exaggeration of the deformation accents subtle deviations and supports the viewer in correctly interpretating of the underlying deformation. The paper at hand presents the new method for the visualization of deformation data, as well as some examples.
