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.
Journal ArticleDOI
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.

Reconstruction of 3D building models from aerial images and maps
Ildiko Suveg,George Vosselman +1 more
TL;DR: In this article, a 3D building reconstruction method that integrates the aerial image analysis with information from large-scale 2D Geographic Information System (GIS) databases and domain knowledge is presented.

Fast vision-guided mobile robot navigation using model-based reasoning and prediction of uncertainties
Akio Kosaka,Avinash C. Kak +1 more
TL;DR: A special aspect of the model-based vision system is the sequential reduction in the uncertainty as each image feature is matched successfully with a landmark, allowing subsequent features to be matched more easily; this is a natural by-product of the manner in which the system uses Kalman filter-based updating.

A Novel Representation and Feature Matching Algorithm for Automatic Pairwise Registration of Range Images
TL;DR: This work presents a novel feature matching algorithm for automatic pairwise registration of range images which is robust to the resolution of the range images, the number of tensors per view, the required amount of overlap, and noise.
Journal ArticleDOI
Superquadrics for segmenting and modeling range data
TL;DR: It is shown that superquadrics can directly be recovered from unsegmented data, thus avoiding any presegmentation steps (e.g. in terms of surfaces), and the approach is based on the recover-and-select paradigm.

A real-time expectation-maximization algorithm for acquiring multiplanar maps of indoor environments with mobile robots.
Sebastian Thrun,C. Martin,Yufeng Liu,Dirk Hähnel,Rosemary Emery-Montemerlo,Deepayan Chakrabarti,Wolfram Burgard +6 more
TL;DR: In this paper, a real-time algorithm for acquiring compact 3D maps of indoor environments, using a mobile robot equipped with range and imaging sensors, is presented. But this algorithm is not suitable for indoor environments.
