About the Speaker/Moderator

Prof. Holsts (*1986) Forschungsgebiet ist der Bereich der Ingenieurgeodäsie. Seine Forschungsschwerpunkte liegen auf der Entwicklung fortschrittlicher Methoden für die geodätische Überwachung von Infrastruktur-, Industrie- und Umweltobjekten, der Automatisierung des hochgenauen statischen und mobilen Laserscannings und der Punktwolkenprozessierung sowie der Qualitätsanalyse geodätischer Sensoren. Anwendung findet seine Forschung bei einer Vielzahl interdisziplinärer Aufgabenstellungen im Kontext der Digitalisierung der Realität.

Prof. Holst studierte an der Universität Bonn Geodäsie und Geoinformation mit Schwerpunkt auf Ingenieurgeodäsie und Parameterschätzung. Anschließend blieb er der Universität Bonn als Wissenschaftlicher Mitarbeiter und Dozent erhalten. Seine Promotion schloss er 2015 mit Auszeichnung ab.  Nachfolgend übernahm er die Leitung einer Forschungsgruppe zum Thema Laserscanning und der geometrischen Analyse von Oberflächen. Im Jahr 2021 wurde Prof. Holst als Ordinarius auf den Lehrstuhl für Ingenieurgeodäsie an die TUM berufen.

Prof. Holst ist seit 2021 Mitglied des Vorstandsrates des DVW Bayern e.V. und er leitet seit 2023 den DVW-Arbeitskreis „Mobile und autonome Sensorsysteme“

Enhancing Geospatial Workflows with Core Surveying Solutions

New developments in measurement technologies are changing how we work in geospatial fields by making things faster, more accurate, and better connected. This presentation looks at how improved automation helps surveyors collect data quickly and with fewer errors, even in tough environments. We also emphasise the crucial role of mobile connectivity in sharing data, collaborating between field and office, and managing sensors in real-time, helping teams to stay flexible and informed. These core surveying solutions come together to create new, efficient workflows that tackle major challenges in the geospatial industry.

Static and Mobile Scanning – Best of Both Worlds

Mobile laser scanning using SLAM is increasingly transforming the industry. Renowned for its speed and efficiency, it prompts the question whether static scanning is now obsolete—or if there are underlying limitations. This presentation aims to critically examine both approaches and propose a solution that integrates the advantages of both worlds.

Use of fiber optical cables for structural health monitoring and traffic flow analyses

Optical fibers are commonly used for telecommunications. However, during data transmission, a small proportion of the coupled light is reflected back to the source at each point on the optical fiber. By analyzing the reflected signal, the strains, temperatures or vibrations along the entire route can be recorded seamlessly. This contribution shows how distributed fiber optic sensing (DFOS) can be used in structural health monitoring, e.g. to detect cracks in bridges and to determine natural frequencies. In some cases, existing communication lines can be used for these applications, which means that no installation effort is required on site. This is especially true for traffic flow analyses, as communication lines are often either embedded directly in the road structure or laid just next to the road. Distributed acoustic sensing (DAS) can be used to detect and classify individual vehicles. The speed and direction of travel can also be derived from the measurement data. The challenge here is the large amounts of data of several gigabytes per minute.

Integration of updated laser scans into as-built point clouds for urban digital twins

Urban digital twins should reflect the urban infrastructure semantically and geometrically as accurately as possible, but also in a timely manner. Therefore, regular updating of existing existing point clouds is necessary in order to do justice to infrastructural changes, e.g. in the context of construction measures. For this purpose, cities often use terrestrial laser scanning or mobile ground-based laser scanning (car, bicycle, backpack), as this allows small areas to be re-measured efficiently. These "new" point clouds must then be efficiently integrated into the existing point clouds so that consistent geoinformation is created. This presentation discusses solutions in this regard and describes a workflow that automatically registers point clouds in as-built point clouds despite many outliers and disturbance points, depending on the geometric richness of the urban development.
