Abstract

This works describes an approach to lane-precise localization on current digital maps. A particle filter fuses data from production vehicle sensors, such as GPS, radar, and camera. Performance evaluations on more than 200 km of data show that the proposed algorithm can reliably determine the current lane. Furthermore, a possible architecture for an intuitive route guidance system based on Augmented Reality is proposed together with a lane-change recommendation for unclear situations.

Abstract

In Global Navigation Satellite Systems (GNSS), the on-board clocks are a key component from which timing and navigation signals are generated. This thesis reviews the performance of the first Passive Hydrogen Maser (PHM) launched by the Galileo system in 2008; and demonstrates how the new PHM can be consider as the best clock in space, pushing the physical clock error contribution below the noise floor of geodetic time transfer capabilities. Furthermore, overall GNSS clock peformance is reviewed

Abstract

In this work, an intelligent human-machine interface (HMI) for human worker activity recognition in industrial environments is presented. The interface consists of components for robust and accurate 3D position estimation in workspace environments, the recognition of task-related worker activities and human-computer interaction via gestures. All components of the presented HMI are flexible with respect to applications and can be transferred to other activity recognition problems, as well.

Abstract

In der vorliegenden Abhandlung wird ein System zur autonomen 3D-Umweltmodellierung vorgestellt, welches auf den drei Hauptprozessen Datenaufnahme, Datenintegration und Aktionsplanung beruht. Basis der Modellierung sind dichte Tiefenbilder, generiert durch einen rotierenden Zeilenscanner, mit Punktmerkmalen. Durch die Registrierung aller Daten können die Fehler der odometrischen Lagebestimmung minimiert werden. Anhand der ermittelten 3D-Daten wird die nächste beste Aufnahmeposition ermittelt.

Abstract

Wirbelstrom-Sensoren ermöglichen die Realisierung einer rein bordautonomen Ortung von Schienenfahrzeugen. Diese basiert dabei auf zwei diversitären Verfahren. Zum einen wird die Geschwindigkeit berührungslos gemessen, zum anderen lassen sich Weichen und Weichenbauteile detektieren und mit einem Bayes-Klassifikator klassifizieren. Gestützt mit einem Hidden-Markov-Modell (HMM) zur Modellierung der Infrastruktur lässt sich eine absolute Position bestimmen und somit ein Ortungssystem realisieren.

Abstract

Computer assisted surgery systems intraoperatively support the surgeon by providing information on the location of hidden risk and target structures during surgery. However, soft tissue deformations make intraoperative registration (and thus intraoperative navigation) difficult. In this work, a novel, biomechanics based approach for real-time soft tissue registration from sparse intraoperative sensor data such as stereo endoscopic images is presented to overcome this problem.

Abstract

The new concept for mobile environmental education extends the traditional media-based environmental interpretation by means of a mobile context-aware computer. This mobile nature guide system can assist its user during self-determined exploration by adapting its presentation to the usage situation, preferences and current environmental conditions. The impact of the prototype mobile nature guide on environmental literacy and user satisfaction has been compared to traditional media in the field.
