Instant Outdoor Localization and SLAM Initialization from 2.5D Maps
We present a method for large-scale geo-localization and global tracking of mobile devices in urban outdoor environments. In contrast to existing methods, we instantaneously initialize and globallyExpand

Handling pure camera rotation in keyframe-based SLAM
Handling degenerate rotation-only camera motion is a challenge for keyframe-based simultaneous localization and mapping with six degrees of freedom. Existing systems usually filter correspondingExpand

Homography-based planar mapping and tracking for mobile phones
We present a real-time camera pose tracking and mapping system which uses the assumption of a planar scene to implement a highly efficient mapping algorithm. Our light-weight mapping approach isExpand

Deskotheque: Improved Spatial Awareness in Multi-Display Environments
In this paper we present the multi-display environment Deskotheque, which combines personal and tiled projected displays into a continuous teamspace. Its main distinguishing factor is a fine-grainedExpand

Automatic configuration of spatially consistent mouse pointer navigation in multi-display environments
Multi-display environments combine displays of various form factors into a common interaction space. Cross-display navigation techniques have to provide transitions to move the mouse pointer acrossExpand

Global 6DOF Pose Estimation from Untextured 2D City Models
We propose a method for estimating the 3D pose for the camera of a mobile device in outdoor conditions, using only an untextured 2D model. Previous methods compute only a relative pose using a SLAMExpand

Multi projector displays using a 3D compositing window manager
The usage of projected displays in everyday office environments is still uncommon due to deficiencies in nowadays projection systems. An automatic calibration routine for multi-projector setupsExpand
