In this paper we describe a flexible approach for determining the relative orientation of the camera with respect to the scene. The main premise of the approach is the fact that in man-made environments, the majority of lines is aligned with the principal orthogonal directions of the world coordinate frame. We exploit this observation towards efficient detection and estimation of vanishing poin...

Zusammenfassung Dieser Beitrag der Zeitschrift Gruppe. Interaktion. Organisation. (GIO) stellt den Kompass Digitalisierung als soziotechnische Gestaltungshilfe für Führungskräfte im Kontext von Digitalisierungsvorhaben vor. Obwohl Forschung in letzten Jahren Zuge Auseinandersetzung um Industrie 4.0 und KI eine kleine Renaissance erfahren hat, wurden bisher kaum soziotechnisch fundierte Führungs...

A number of recent studies address systems of mobile autonomous robots from a distributed computing point of view. Although such systems employ robots that are relatively weak and simple (i.e., dimensionless, oblivious and anonymous), they are nevertheless expected to have strong fault tolerance capabilities as a group. This paper studies the partitioning problem, where n robots must divide the...

In complex aeronautical and space engineering systems, conventional sensors used for environment perception fail to determine the orientation because of the influences of the special environments, wherein geomagnetic fields are exceptional and the Global Positioning System is unavailable. This paper presents a fisheye-lens-based visual sun compass that is efficient in determining orientation in...

Recently, Haferlach, Wessnitzer, Mangan, and Webb (2007) reported on the production of a novel neural model of the animal behavior known as path integration, a navigation process requiring a compass and an odometer. Here, we comment on comparisons that their paper makes with our earlier work (Vickerstaff & Di Paolo, 2005) where we also evolved a neural model of path integration. The authors mak...

A compass based purely on visual information would be a useful navigational tool for robots working in environments where magnetic and GPS compass information is not available. A visual compass processes a pair of panoramic images taken from two different positions and estimates the orientation change between them. We present in this paper several well known algorithms useful for the developmen...
