Image Based Indoor Navigation
Over the last years researchers proposed numerous indoor localisation and navigation systems. However, solutions that use WiFi or Radio Frequency Identification require infrastructure to be deployed in the navigation area and infrastructure-less techniques, e.g. the ones based on mobile cell ID or dead reckoning suffer from large accuracy errors. In this Thesis, we present a novel approach of i...
متن کاملNavigation by Image-Based Visual Homing
Almost all autonomous robots need to navigate. We define navigation as do Franz & Mallot (2000): “Navigation is the process of determining and maintaining a course or trajectory to a goal location” (p. 134). We allow that this definition may be more restrictive than some readers are used to it does not for example include problems like obstacle avoidance and position tracking but it suits our p...
متن کاملImage Processing for Vision Based Navigation
Optical imagery provides a powerful means of autonomous navigation for spacecraft in the vicinity of Solar system bodies, where the communication delay may be much longer than the dynamical timescales. Cameras are now routinely included among the suite of sensors used to guide exploratory spacecraft, with information extracted from the images fused with that of other sensors to estimate the spa...
متن کاملAn Image-Based System for Urban Navigation
We describe the prototype of a system intended to allow a user to navigate in an urban environment using a mobile telephone equipped with a camera. The system uses a database of views of building facades to determine the pose of a query view provided by the user. Our method is based on a novel wide-baseline matching algorithm that can identify corresponding building facades in two views despite...
متن کاملImage based navigation using a topological map
A new approach on robot navigation is described which enables the robot to drive through the environment using only a vision system as its sensor. In an exploration phase the robot is driven manually through the environment while taking images. By computing similarities between these images the robot constructs a topological map in the form of an appearance graph. Navigation on this graph invol...
