Measuring of Large Structures
Work area
The main focus of the Measuring of Large Structures development team is on the capture, analysis and visualization of 3D measuring data in the field of production technology. An interdisciplinary team and a broad spectrum of digitalization methods for stationary and mobile applications are the basis of innovative solutions even under difficult conditions (e.g. underwater).
Using the latest measurement technology for capturing the shape and location of large structures provides the foundation for application-specific development of analysis and evaluation methods of geometric data. Together with industry partners, the research focus of 3D data-capturing develops concepts of measurement and quality management capturing the actual build state of various objects. A qualification of the measurement process for quality control as well as the development of the entire process chain of data acquisition is performed, the results are presented accordingly and the information is returned to the production process.
The research field data analysis focuses on solving fundamental questions regarding the interpretation of multidimensional sensory data. The overall objective is customized software engineering for the automated analysis of high-resolution 3D point clouds and additional data sources. With application-specific development for automated extraction of object-relevant information of 2D, 3D or higher dimensional data, modelling techniques are developed, measurement and analysis processes are automated and the state of the object is derived.
We have expanded our competencies and increased the personnel in the field of evaluation and analysis of sound-based sensor systems for application in monitoring systems, production monitoring and, in particular, in combination with the existing competences in geometric 3D measurement technology (sensor data fusion).

Data collection
3D HydroMapper
Hybrid 3D inventory data capture and model-based testing of waterway structures for sustainable infrastructure lifecycle management
As part of the joint project "Hybrid 3D as-built data acquisition and model-based inspection of transport water structures for sustainable infrastructure lifecycle management - 3D HydroMapper", Fraunhofer IGP is developing a system for the digital inspection of transport water structures in collaboration with Dr. Hesse und Partner Ingenieure in Hamburg (dhp:i), WKC Hamburg GmbH (WKC), the Geodetic Institute Hannover (GIH) and the port operator and service provider Niedersachsen Ports (NPorts). The unique selling point is the extensive automation of the measurement, evaluation and inspection process for structures located above and below water. As a result, the recording speed can be increased, the scope of the inspection expanded and, for the first time, a comprehensive digital construction model for port structures can be created and updated.
