Assessing Steel Bridges Structural Condition using Light Detection and Ranging (LiDAR)

For this research project, our team investigated the application of LiDAR-based technologies in steel bridge maintenance and inspection. The project focused on the steel bridge that spans Highland Dr, located on Cal Poly's Campus. Using terrestrial laser scanning and software like Scene and CloudCompare, we were able to register scans and compare point clouds. We also worked on the point clouds in MATLAB, with the ultimate goal of being able to generate an as-built BIM.
