Abstract:This research is investigating the use of high resolution 3D terrestrial laser scanners as tools to capture geometric data of complex scenes for structural engineering applications. Laser scan technology is continuously improving, with commonly available scanners now able to capture over 100,000 points per second with an accuracy of ~1 mm. This research focuses on determining the applicability of laser scanning to structural engineering applications, including structural health monitoring, collapse assessment, and post-hazard response assessment. One of the keys to this work is to establish a process for extracting important information from raw laser-scanned data sets. Once such a process is fully developed, laser scanning has the potential to play an important role in linking and sharing experimental and computational structural research. Previous work in this area has created a foundation of basic data processing steps. Additional steps and modifications to existing algorithms are presented to advance the performance of data processing on complete point clouds. The outcome of this research enables processing of lasers scans of complex structures to assist with advanced analysis, monitoring, and assessment.
