Navigation Framework Using Visual Landmarks and a GIS
نویسندگان
چکیده
In an unfamiliar environment we spot and explore all available information which might guide us to a desired location. This largely unconscious processing is done by our trained sensory and cognitive systems. These recognise and memorise sets of landmarks which allow us to create a mental map of the environment, and this map enables us to navigate by exploiting very few but the most important landmarks stored in our memory. In this paper we present a route planning, localisation and navigation system which works in real time. It integrates a geographic information system of a building with visual landmarks for localising the user and for validating the navigation route. Although designed for visually impaired persons, the system can also be employed to assist or transport persons with reduced mobility in way finding in a complex building. © 2013 The Authors.

متن کاملExtracting Landmarks for Car Navigation Systems Using Existing Gis Databases and Laser Scanning
Today’s car navigation systems provide driving instructions in the form of maps, pictograms, and spoken language. However, they are so far not able to support landmark-based navigation, which is the most natural navigation concept for humans and which also plays an important role for upcoming personal navigation systems. In order to provide such a navigation, the first step is to identify appro...
متن کاملA visual landmark framework for mobile robot navigation
Vision has become a major element in mobile robot navigation and many strategies relying on images have already been proposed, based on environment representation either by image databases[10] or by visual landmarks. Classically, the latter are detected by the robot, mapped into the environment representation and recognized during the execution of a navigation task. In general, the robot’s posi...
متن کاملGPS Jamming Detection in UAV Navigation Using Visual Odometry and HOD Trajectory Descriptor
Auto-navigating of unmanned aerial vehicles (UAV) in the outdoor environment is performed by using the Global positioning system (GPS) receiver. The power of the GPS signal on the earth surface is very low. This can affect the performance of GPS receivers in the environments contaminated with the other source of radio frequency interference (RFI). GPS jamming and spoofing are the most serious a...
متن کاملA generic framework for topological navigation of urban vehicle
In this paper, we present a generic framework for urban vehicle navigation using a topological map. This map is built by taking into account the non-holonomic behaviour of the vehicle. After a localization step, a sensory route is extracted to reach a goal. This route is followed using a sensor-based control strategy, based on the vehicle model and computed from the state extracted from the cur...
