Abstract:

This paper presents two methods for direct geo-referencing of terrestrial laser scans. The first approach deals with the direct estimation of the sensor position and orientation with GNSS antennas mounted on a laser scanner. In the second approach a mobile mapping system is presented. This system is based on an integration of INS and GPS for positioning and orientation tasks of the hybrid sensor system formed by one laser scanner and additional navigation sensors. The paper presents the common principle, the current system setup as well as the benefit of both variants for direct geo-referencing of terrestrial laser scans.

In diesem Beitrag werden zwei Varianten zur direkten Georeferenzierung von terrestrischen Laserscans vorgestellt. Für eine statische Plattform wird die Position und Ausrichtung des Laserscanners direkt durch ein integriertes kinematisches GNSS bestimmt. In der zweiten Aufnahmevariante wird die Kombination aus inertialem Messsystem (INS) und GPS genutzt, um das hybride Sensorsystem zu orientieren. Das gemein-same Prinzip beider Ansätze wird im Kontext der Georeferenzierung erläutert. Aktuelle Realisierungen werden dargestellt und schließlich wird daraus das Potentialbeider Varianten für die direkte Georeferenzierung abgeleitet.

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.
