In task executing it is necessary to make decisions. Very often decisions depend on special conditions and circumstances. A decision support may be helpful if the best choice search is based on a multidimensional space of possibilities. In geospatial based applications positioning and localization are essential criteria for most ongoing decisions. Where are you and where do you want to go? The general...
In today's world of urban traffic environment, there is an immediate requirement to impose safety measures to avoid fatal accidents. To ensure safe driving, vehicles can be made intelligent by equipping them with sensors. This means that multiple sensors can be incorporated on the vehicle. Such system can act as a warning strategy that guides the driver of the vehicle to make right decisions at times...
This paper presents an interacting multiple model (IMM)-based extended Kalman filter (EKF) approach for the Global Positioning System (GPS) navigation processing. The well-known extended Kalman filter has been widely applied to the GPS navigation processing. The ldquosoft-switchingrdquo IMM estimator obtains its estimate as a weighted sum of the individual estimates from a number of parallel filters...
Maneuvering large vehicles like trucks is a challenging task because their drivers often cannot see the closest surrounding area of the vehicle. This paper presents a system providing the driver with a bird's-eye view of the surrounding area on a single display. This view is constructed by stitching together cutouts from two omnidirectional images acquired by catadioptric cameras, which are placed...
The placement of multiple antennas on an air vehicle is one possible practice for overcoming signal obstruction created by vehicle maneuvering during air-to-ground transmission. Unfortunately, for vehicle attitudes where more than one of these antennas has a clear path to the receiving station, this practice also leads to self-interference nulls, resulting in dramatic degradation in the average signal...
