Hand-held Mobile Laser Scanning - Investigation and Evaluation in Complex Environments
Complex indoor environments, such as narrow underground passages, still represent a challenge for the majority of the available indoor mapping techniques. The talk aims to address this topic and present the R&D work realized in the FBK-3DOM laboratory with the Geoslam Zeb1 hand-held laser scanning system. The sensor characterization is preliminary discussed in order to investigate the accuracy potential of the system. Several experiments focused on the surveying of heritage tunnels, WWI underground tunnels and fortifications are then shown. Finally a method based on GoPro cameras coupled with the Zeb1 system to associate color information to the acquired point clouds is also presented.
