Proceedings ArticleDOI
From structure-from-motion point clouds to fast location recognition
TL;DR: A fast location recognition technique based on structure from motion point clouds is presented, and Vocabulary tree-based indexing of features directly returns relevant fragments of 3D models instead of documents from the images database.
Journal Article
Point Clouds: Lidar versus 3D Vision
Franz Leberl,Arnold Irschara,Thomas Pock,Philipp Meixner,Michael Gruber,S. Scholz,Alexander Wiechert +6 more
TL;DR: In this article, the authors compare point clouds from aerial and street-side lidar systems with those created from images, and show that the photogrammetric accuracy compares well with the lidar-method, yet the density of surface points is much higher from images.
Proceedings ArticleDOI
Wide area localization on mobile phones
TL;DR: A fast and memory efficient method for localizing a mobile user's 6DOF pose from a single camera image, usually requiring only a few megabytes of memory, thereby making it feasible to run on low-end devices such as mobile phones.
Photogrammetric Camera Network Design for Micro Aerial Vehicles
TL;DR: This work proposes a novel camera network design algorithm suitable for MAVs for close range photogrammetry that exploits prior knowledge of the surrounding and automatically determines a set of camera positions that guarantees important constraints for image based 3D reconstruction.
Proceedings ArticleDOI
Natural landmark-based monocular localization for MAVs
TL;DR: This work introduces a novel algorithm for monocular visual localization for MAVs based on the concept of virtual views in 3D space that directly allows global registration and is well suited for long-term autonomous navigation.
