Data Collection through Laser Scanning

Digitalization in the Construction Industry means that preparatory building documentation is becoming more and more important in the construction industry. Inventory data collection in 3D has proven itself over the years, as it offers new, diverse options compared to 2D documentation. The planning of larger and increasingly complex properties often also means a higher increase in construction volumes. For architects and engineers, this requires a growing range of preparatory work before the actual planning can begin. This requires new innovative methods for recording inventory data. They should be generated as quickly, detailed and comprehensively as possible while keeping costs within limits.

Laserscanners in use

Using the 3D laser scan from the Patricia Lumumba Gallery in Berlin (shown below), the creation of a digital twin is described. For this purpose, the scanner scanned the interior and associated equipment using a laser beam and scanned it in the defined measurement range at up to 1 million 3D measurement points per second. With the associated software, a holistic and spatial image of the captured object can be viewed in the form of a point cloud. At the same time, the scanner created a 360° panorama from the scanner's position. In this way, the room is recorded precisely and in high resolution.

Create a digital twin

In the example shown below, the result of the 3D laser scan from the Patricia Lumumba Gallery in Berlin is shown. For this purpose, the scanner scanned the interior and associated equipment using a laser beam and scanned it in the defined measurement range at up to 1 million 3D measurement points per second. With the associated software, a holistic and spatial image of the captured object in the form of a point cloud can be viewed directly on site, a few seconds later. At the same time, the scanner created a 360° panorama from the scanner's position. In this way, the room is recorded precisely and in high resolution. The point cloud was then used to generate a digital twin from inventory data collection.

Transforming real worlds into immersive worlds

The digital twin of the real Patricia Lumumba Gallery was used as an illustrative example as part of the research project to show what options inventory data collection in 3D can offer. For example, some results from students from Jade University on the topics of Augmented Reality (AR) and Artificial Intelligence (AI) were exhibited at the Experience:Space at the University Future:Festival in Berlin from April 26-28, 2023. At the same time, the digital exhibition space was used to display all the results of both seminars and to combine reality and virtuality on site.
