Classical 3D reconstruction has traditionally focused on low-level representations, and this workshop addresses the need for higher-level, structured and parametric representations like CAD models from images and point clouds, with implications for construction, manufacturing, urban planning, and related fields. The workshop aims to foster interdisciplinary collaboration between 3D vision researchers, photogrammetry, graphics, machine learning, and other domains where structured 3D representations are critical. To advance research in this area, the workshop introduces two large-scale datasets: S23DR, a collection of 3D models with corresponding multiview images, and Building3D, a city-scale dataset for building wireframe model generation from aerial LiDAR. By providing these resources and promoting collaboration, the workshop seeks to catalyze multi-view structured 3D reconstruction trends, bridge industry-academia gaps, and enable applications in urban planning, disaster management, and other critical areas.
