With the acceleration in three-dimensional (3D) high-frame-rate sensing technologies, dense point clouds collected from multiple standpoints pose a great challenge for the accuracy and efficiency of registration. The combination of coarse registratio

The literature of social class and inequality is not only diverse and rich in sight, but also complex and fragmented in structure. This article seeks to map the topic landscape of the field and identify salient development trajectories over time. We

The automation of digital twinning for existing bridges from point clouds has yet been solved. Whilst current methods can automatically detect bridge objects in points clouds in the form of labelled point clusters, the fitting of accurate 3D shapes t

Prior studies reported that the time needed to manually convert a point cloud to an as-is geometric model using cutting edge modelling software is ten times greater than the time needed to obtain the point cloud. The laborious nature of manually mode

Statistical machine learning models should be evaluated and validated before putting to work. Conventional k-fold Monte Carlo cross-validation (MCCV) procedure uses a pseudo-random sequence to partition instances into k subsets, which usually causes

This paper describes the design, implementation and benchmarking of a framework for automating the process of geometric digital twinning for existing slab and beam-and-slab bridges. Called Lukis, the framework followed a top-down strategy to detect a

We present an exploratory analysis of the geometric accuracy of digital twins generated for existing infrastructure using point clouds. A fundamental feature of digital twins is their 3D geometry. The Level of Geometric Accuracy is a vital specificat

Point cloud pre-processing is essential for emerging applications such as digital twinning but currently requires a lot of manual effort before the resulting data can be used. Practitioners usually use default scan range settings to take full scans,
