Research projects

The potential to automate and simplify processes on construction sites is still huge. Construction progress, for example, is recorded via photo documentation, which is time-consuming and sometimes even needs separate personnel. VRVis and rmDATA, specialist in geoinformatics, are supporting digitalisation in this context: together, they are testing and analysing the use of mobile phones and tablets with LiDAR (Light Detection and Ranging) and high-resolution cameras for near-surface civil engineering. LiDAR is a technology that uses light impulses to survey the environment, providing three-dimensional laser scans. Measurements of laying depths, trench lengths and widths as well as excavations can be carried out in a 3D model of the construction site. At the same time, the method delivers high-quality documentation.Das Potenzial, Prozesse auf Baustellen zu automatisieren und zu vereinfachen, ist aktuell noch groß. Baufortschritte etwa werden via Fotodokumentation erfasst, was sich aufwändig gestaltet und teilweise von separatem Personal durchgeführt wird.

Creating a basis for consistent, digital 3D documentation

The cooperation between VRVis and rmDATA is part of the "AI5production" digitalisation initiative. It involves a detailed investigation of how accurate mobile devices can record construction sites with LiDAR and which factors influence the outcome. There are already tools and workflows, used to derive point clouds and reconstructions from mobile LiDAR images. However, they are primarily suitable for measuring medium-sized objects (e.g. furniture) or interiors.

There is a need for an accurate analysis of the limits of light impulses for the documentation of civil engineering structures in outdoor areas. VRVis and rmDATA are tackling this task in their "test before invest" research collaboration. Their aim is to develop a basis for an end-to-end digital, mobile solution for the 3D documentation of construction sites, which will also make the billing within civil engineering easier.

More sustainable construction processes

With the help of a user-friendly, mobile application, the number of journeys to a construction site is decreasing. People who are already on site take over the recording or any subsequent documentation with standard mobile devices - no separate personnel are required. In addition, precise documentation of the processes enables objects to be checked and maintained specifically in the future.
