• Abstract:
  In this project we explore the usage of 3D reconstruction to monitor and measure landslides. We took images of a landslide prone area in late Fall 2024 and late Spring 2025. We used COLMAP to make a 3D point cloud out of the images and with CloudCompare we measure the difference between the two-point clouds and thereby detect changes. In our experiment we are able to detect a rock that was dislodged, vegetation growth and accumulation of rocks.
