Automated Progress Controlling and Monitoring Using Daily Site Images and Building Information Modelling
TL;DR: The proposed photogrammetric Multi-View Stereo method has extensively improved the accuracy of generated points cloud compared to the SFM/CMVS/PMVS algorithm and may present a novel and robust tool for automated progress monitoring in construction projects.

Skeleton-based discrepancy feedback for automated realignment of industrial assemblies
Mohammad Nahangi,Carl T. Haas +1 more
TL;DR: In this article, a constrained iterative closest point (ICP) algorithm is used to identify the points making up each straight segment, the skeletons are clustered, and a straight line is fit to each resulting cluster.
Journal ArticleDOI
Automated assembly discrepancy feedback using 3D imaging and forward kinematics
TL;DR: In this paper, the authors propose a framework for automated refitting and realignment of steel structures, modules, and pipe spools using a constrained registration step to overcome the incapabilities of the current discrepancy analysis approaches.
Journal ArticleDOI
Conceptual framework for integrating BIM and augmented reality in construction management
TL;DR: This work aims to analyse the potential of AR association to BIM, by adopting an approach based on literature review, and found that the case study approach was adopted in 41% of the publications analysed.
Journal ArticleDOI
Ground volume assessment using ’Structure from Motion’ photogrammetry with a smartphone and a compact camera
TL;DR: In this paper, the Structure-from-Motion (SfM) method was used to calculate the volume of anthropogenic microtopography of the embankment of a known volume.

Distinctive Image Features from Scale-Invariant Keypoints
TL;DR: This paper presents a method for extracting distinctive invariant features from images that can be used to perform reliable matching between different views of an object or scene and can robustly identify objects among clutter and occlusion while achieving near real-time performance.
Journal ArticleDOI
Random sample consensus: a paradigm for model fitting with applications to image analysis and automated cartography
TL;DR: New results are derived on the minimum number of landmarks needed to obtain a solution, and algorithms are presented for computing these minimum-landmark solutions in closed form that provide the basis for an automatic system that can solve the Location Determination Problem under difficult viewing.

A Comparison of Affine Region Detectors
Krystian Mikolajczyk,Tinne Tuytelaars,Cordelia Schmid,Andrew Zisserman,Jiri Matas,Frederik Schaffalitzky,Timor Kadir,L. Van Gool +7 more
TL;DR: A snapshot of the state of the art in affine covariant region detectors, and compares their performance on a set of test images under varying imaging conditions to establish a reference test set of images and performance software so that future detectors can be evaluated in the same framework.
Journal ArticleDOI
An optimal algorithm for approximate nearest neighbor searching fixed dimensions
TL;DR: In this paper, it was shown that given an integer k ≥ 1, (1 + ϵ)-approximation to the k nearest neighbors of q can be computed in additional O(kd log n) time.

Modeling the World from Internet Photo Collections
TL;DR: This paper presents structure-from-motion and image-based rendering algorithms that operate on hundreds of images downloaded as a result of keyword-based image search queries like “Notre Dame” or “Trevi Fountain,” and presents these algorithms and results as a first step towards 3D modeled sites, cities, and landscapes from Internet imagery.
