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.

Research trends and opportunities of augmented reality applications in architecture, engineering, and construction
TL;DR: This paper discusses trends in AR applications for architecture, engineering, construction, and facility management (AEC/FM), and outlines the research trends and opportunities for applying AR in the fields of AEC/ FM.
Journal ArticleDOI
Computer vision techniques for construction safety and health monitoring
TL;DR: This paper categorizes previous studies into three groups-object detection, object tracking, and action recognition-based on types of information required to evaluate unsafe conditions and acts, and provides researchers insights into advancing knowledge and techniques for computer vision-based safety and health monitoring.

Application of D4AR – A 4-Dimensional augmented reality model for automating construction progress monitoring data collection, processing and communication
TL;DR: This research focuses on exploring application of unsorted daily progress photograph logs available on any construction site as a data collection technique and the results of progress comparison between as-planned and as-built performances are visualized in the D4AR (4D Augmented Reality) environment using a traffic light metaphor.

On the geometry and algebra of the point and line correspondences between N images
O. Faugeras,Bernard Mourrain +1 more
TL;DR: The formalism of the Grassmann-Cayley algebra is proposed to use as the simplest way to make both geometric and algebraic statements in a very synthetic and effective way (i.e. allowing actual computation if needed).

Automated retrieval of 3D CAD model objects in construction range images
Frédéric Bosché,Carl T. Haas +1 more
TL;DR: This paper presents a new approach for robust automated recognition/retrieval of 3D CAD objects in range point clouds in the Architectural/Engineering/Construction & Facility Management (AEC-FM) context and demonstrates how this approach can be used for efficiently assessing construction progress.
Journal ArticleDOI
Visualization of construction progress monitoring with 4D simulation model overlaid on time-lapsed photographs
TL;DR: In this paper, the authors proposed a visualization of performance metrics that aims to represent progress deviations through superimposition of four-dimensional (4D) as-planned model over time-lapsed photographs in single and comprehensive visual imagery.
