Laser Scanner–Based Deformation Analysis Using Approximating B-Spline Surfaces

Abstract: Due to the increased use of areal measurement techniques, such as laser scanning in geodetic monitoring tasks, areal analysis strategies have considerably gained in importance over the last decade. Although a variety of approaches that quasi-continuously model deformations are already proposed in the literature, there are still a multitude of challenges to solve. One of the major interests of engineering geodesy within monitoring tasks is the detection of absolute distortions with respect to a stable reference… Show more

“…If the number of points satisfying Equation 2 is below a certain minimum number, another RANSAC-iteration is performed. Caspary, (2013) and Harmening et al (2021) provide approaches to select freely definable parameters (factor 𝜏, maximum number of iterations, minimum number of model-compliant points 𝑛 ) of this algorithm.…”

“…This article presents generally available tools thanks to which it will be possible to widely use the proposed solutions in commercial analyses of deformations in engineering objects. Terrestrial laser scanning (TLS) technology is widely used for the monitoring and determination of surface deformations (Harmening et al, 2021;Yang et al, 2021;Gawronek et al, 2019;Kovanič et al, 2019;Liu et al, 2020). It provides quasi-continuous information about the surveyed surface in the form of a point cloud with X,Y,Z coordinates, complemented by the reflection intensity.…”
