3D reconstructions, derived from Structure from Motion (SfM), have broad applications in virtual reality, cultural heritage preservation, architectural modeling, robotics, and medical imaging, facilitating accurate mapping and navigation. These techniques utilize geometric principles and image-based methods to reconstruct 3D scenes from 2D images.

The objective of this tutorial session is to introduce participants to the core concepts of SfM and Multi-View Stereo (MVS) reconstruction using open-source libraries like openMVG (Multiple View Geometry) and openMVS (Multi-View Stereo). Participants will gain hands-on experience processing image datasets to create 3D reconstructions from various viewpoints. The session will cover:
