Abstract

Fast and highly precise geometric shape acquisition for in-process control poses a significant challenge for all kind of measurement systems, particularly in the context of large-scale structures. Conventional systems like laser trackers or photogrammetric setups are commonly employed for this purpose. However, these instruments do not provide real-time measurements, and their limitations become increasingly pronounced as the object size grows. Real-time capability, in contrast, offers substantial advantages for closed control loop forming processes in industries such as aerospace and wind energy. This requirement is addressed by our approach employing a dense network of wireless sensor probes that determine the shape of the object through the measurement of surface normal relative probe positions. Within this architecture, all measurement data is aggregated and processed in a central unit at a fixed sampling interval that remains independent of the network size. As a result, the overall measurement time stays constant, even for large-scale structures. In this work, we compare the measurement accuracy and repeatability of this novel wireless sensor network with the conventional approaches referenced above, following the procedures defined in DIN ISO 22514.
