Abstract:

This paper focuses on the detection and tracking of vehicles from airborne image sequences to monitor moving traffic. Two different systems are described: the first one is a near real-time tracking algorithm based on normalized cross correlation. The second approach includes model knowledge about driver behavior, traffic dynamics and context to exploit svelocity and trajectory evaluation. The shown results and derived quality measures demonstrate the performance of the proposed systems, in particular the contribution of the traffic model knowledge enhances the correctness of the tracking results. Finally, concluding remarks are given to point out further research.

Dieser Artikel zielt auf das Erkennen und Verfolgen von Fahrzeugen aus luftgetragenen Bildsequenzen zur Überwachung von fließendem Verkehr. Zwei unterschiedliche Systeme werden beschrieben: Das Erste ist ein echtzeitnahes Tracking-Verfahren, welches auf der normalisierten Kreuzkorrelation basiert. Das zweite Verfahren bindet Modellwissen über Fahrerverhalten, Verkehrsdynamiken und Kontext ein, um Geschwindigkeitsund Trajektorienbewertungen auszunutzen. Die Ergebnisse und die abgeleiteten Qualitätsmaße zeigen die Leistungsfähigkeit der Systeme, insbesondere der Beitrag des Verkehrsmodellwissens erhöht die Korrektheit der Trackingergebnisse. Abschließend wird ein Ausblick auf zukünftige Forschungen gegeben.

More about this publication?
  • Photogrammetrie - Fernerkundung - Geoinformation (PFG) is an international scholarly journal covering the progress and application of photogrammetric methods, remote sensing technology and the intricately connected field of geoinformation processing.

    Papers published in PFG highlight new developments and applications of these technologies in practice. The journal hence addresses both researchers and student of these disciplines at academic institutions and universities and the downstream users in both the private sector and public administration.

    PFG places special editorial emphasis on the communication of new methodologies in data acquisition, new approaches to optimized processing and interpretation of all types of data which were acquired by photogrammetric methods, remote sensing, image processing and the computer-aided interpretation of such data in general.

    PFG is the official journal of the German Society of Photogrammetry and Remote Sensing.
