The Piazza Erbe Dataset is a dataset of images used for 3D reconstruction that introduces a hierarchical scheme for computing structure and performance by organizing images into trees with agglomerative-clustering and using an overlap metric as distance.

This dataset was released by the Department of Computer Science at the University of Vienna, and the main publishers were R.Toldo, R. Gherardi, M. Farenzena and A. Fusiello.
