Building Information Modeling (BIM) for existing buildings — Literature review and future needs
TL;DR: Results show scarce BIM implementation in existing buildings yet, due to challenges of (1) high modeling/conversion effort from captured building data into semantic BIM objects, (2) updating of information in BIM and (3) handling of uncertain data, objects and relations in B IM occurring inexisting buildings.

Mobile 3D mapping for surveying earthwork projects using an Unmanned Aerial Vehicle (UAV) system
Sebastian Siebert,Jochen Teizer +1 more
TL;DR: The performance evaluation of a UAV system that was built to rapidly and autonomously acquire mobile three-dimensional mapping data and its execution for the generation of 3D point clouds from digital mobile images is presented.

BIM implementation throughout the UK construction project lifecycle: An analysis
TL;DR: This research demonstrates via 92 responses from a sample of BIM users that collaboration aspects produce the highest positive impact and is most often used in the early stages with progressively less use in the latter stages.

Automatic Creation of Semantically Rich 3D Building Models from Laser Scanner Data
TL;DR: A method to automatically convert the raw 3D point data from a laser scanner positioned at multiple locations throughout a facility into a compact, semantically rich information model that is capable of identifying and modeling the main visible structural components of an indoor environment despite the presence of significant clutter and occlusion.

NURBS curve and surface fitting for reverse engineering
Weiyin Ma,Jean-Pierre Kruth +1 more
TL;DR: In this article, a two-step linear approach is employed for fitting non-uniform rational B-spline curves and surfaces using the measured points, and the weights of the control points are identified from a homogeneous system using symmetric eigenvalue decomposition.
Proceedings ArticleDOI
Parts-based 3D object classification
TL;DR: A parts-based method for classifying scenes of 3D objects into a set of pre-determined object classes that enables a more flexible class representation and allows scenes in which the query object is significantly occluded to be classified.
Journal ArticleDOI
Experiments in curvature-based segmentation of range data
Emanuele Trucco,Robert B. Fisher +1 more
TL;DR: The authors report the results of an extensive testing program aimed at investigating the behavior of important experimental parameters such as the probability of correct classification and the accuracy of curvature estimates, measured over variations of significant segmentation variables.

Specification and implementation of directional operators in a 3D spatial query language for building information models
André Borrmann,Ernst Rank +1 more
TL;DR: The paper presents in-depth definitions of the semantics of two new directional models for extended 3D objects, the projection-based and the halfspace-based model, by using point-set theory notation.

An analysis of geometric modeling in database systems
Alfons Kemper,Mechtild Wallrath +1 more
TL;DR: The data-modeling and computational requirements for integrated computer aided manufacturing (CAM) databases are analyzed, and the most common representation schemes for modeling solid geometric objects in a computer are described.
