Analysis of the influence of range and angle of incidence of terrestrial laser scanning measurements on tunnel inspection
TL;DR: In this article, a methodology to build an error model of the TLS measurements is proposed, where measurement errors are estimated based on two of the factors that mostly affect their magnitude: distance to the object and angle of incidence.

Rapid 3D Energy Performance Modeling of Existing Buildings Using Thermal and Digital Imagery
Youngjib Ham,Mani Golparvar-Fard +1 more
TL;DR: In this article, the authors presented a new approach for actual energy performance modeling of existing buildings using digital and thermal imagery, which consists of an image-based 3D reconstruction pipeline consisting of Structure-fromMotion, Multi-View Stereo, and Voxel Coloring/Labeling, using a new 3D thermal modeling algorithm, a dense thermal point cloud model of the existing building is reconstructed in 3D.

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.

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.
