In a world where precision in construction and environmental modeling is paramount, Vienna-based DGNSS Sensors GmbH has emerged as a leader in leveraging cutting-edge technology to generate highly accurate 3D models. Since 1996, DGNSS has utilized innovative techniques in laser scanning and multi-sensor platforms for a variety of applications, including civil engineering, geo-monitoring, and hydrography. Their advanced methodologies are integral to creating precise and realistic digital representations of buildings, interiors, landscapes, and even complex infrastructure components.
Advanced Techniques in Laser Scanning and Multi-Sensor Platforms
The Core of the DGNSS System
At the heart of DGNSS’s technological prowess lies a measuring platform equipped with diverse sensors and high-resolution 3D scanners mounted on a mobile trolley. This platform collects detailed spatial data by halting at specified points, allowing for meticulous data acquisition. The integration of data streams through a Robot Operating System (ROS) facilitates the creation of an accurate and comprehensive 3D digital twin of the surveyed environment. Recently, the incorporation of inertial accelerometers from ASC into this platform has further refined the accuracy of their models, demonstrating DGNSS’s commitment to continual improvement and precision.
Such advancements are indispensable in an ever-evolving industry where the integration of various data streams is key to generating holistic and precise models. The use of this technology transcends simple data collection; it represents an intersection of engineering, robotics, and environmental science. The ability to create high-resolution point clouds that capture precise geometries in both black and white and color is a testament to the sophisticated nature of these platforms. This multi-sensor approach ensures that the data collected is both accurate and comprehensive, offering stakeholders a reliable foundation for planning and execution.
Applications in Building Information Modeling (BIM)
A significant application of DGNSS’s technology is in Building Information Modeling (BIM), a critical tool in modern construction and building management. As noted by Heinz Stanek, PhD, a Senior Consultant and Product Developer at DGNSS, laser scanning combined with BIM proves invaluable in constructing, maintaining, and efficiently utilizing buildings. These models serve as virtual representations that aid in essential functions like development planning and maintenance scheduling, ensuring every aspect of a building’s lifecycle is meticulously documented and managed.
The integration of data into BIM models facilitates comprehensive collaboration among all stakeholders, promoting efficient planning and execution of construction projects. By generating high-resolution point clouds, DGNSS provides detailed 3D models that capture every nuance of a structure’s geometry. This high level of detail ensures that the BIM models created are not only accurate but also incredibly valuable for ongoing management of the building’s infrastructure, from design to day-to-day operations.
Enhancing Measurement Accuracy and Robustness
Precision in Field Applications
To maintain the highest standards in measurement accuracy, DGNSS continually refines its robotics platform and selects robust components to ensure reliability. Their efforts include a special collaboration to model rail track corridors and infrastructure, where the platform recorded extensive measurement data points and high-resolution images. This meticulous attention to detail underscores the importance of precision engineering in field applications. The collaboration illustrates how advanced sensor technology can be utilized to create highly detailed models that are critical for infrastructure planning and maintenance.
The ability to accurately model rail track corridors not only aids in current maintenance efforts but also in future planning. Detailed models ensure that any changes or developments can be planned with a high degree of confidence. This application is a perfect example of how DGNSS’s technology transcends traditional surveying, providing critical insights that drive effective decision-making and project management.
Testing and Validation of Sensor Technology
Ensuring the precision and compatibility of components is vital for any high-tech platform. In the case of the digital ASC DiSens ECO accelerometer, rigorous testing was conducted at Vienna University of Technology to confirm its suitability. The tests evaluated the sensor’s static long-term performance, its practical application on a 2 km track system, and its compatibility with the ROS data integration system. The results were promising, showcasing the sensor’s outstanding accuracy, low standard deviation, robustness, and efficient data transmission, confirming its integration viability within DGNSS’s systems.
These trials exemplify the commitment to excellence and meticulous attention to detail that defines DGNSS’s approach. By rigorously testing and validating sensor technologies, DGNSS ensures that their platforms not only meet but exceed industry standards. This ongoing dedication to improvement and innovation solidifies their position at the forefront of the technology and environmental modeling sectors.
Continuous Advancements and Interdisciplinary Collaboration
Elevating Platform Capabilities
Renate Bay, Managing Director of ASC Sensors, emphasized the significant value derived from integrating multiple technologies to enable effective communication between sensor systems. This integrated approach characterizes DGNSS’s commitment to a holistic, cohesive solution rather than isolated components. Continuous advancements in their expertise and platform capabilities underscored the potential for high-precision technology in creating detailed 3D models that significantly impact building management, planning, and collaboration in construction projects.
This integrated strategy not only ensures seamless operations but also facilitates the continuous flow of accurate information among all construction stakeholders. By providing a platform that can adapt and evolve with the industry’s needs, DGNSS sets a new standard for efficiency and precision in the field. This holistic approach ensures that the technology remains relevant and effective, regardless of the project’s complexity.
