Datasets

We have devised a number of datasets for curve-based multiview reconstruction and camera estimation algorithms, described in further detail at the end of this webpage.

The Barcelona Pavillion is a realistic synthetic dataset we created for validating curve-based 3D SfM and stereo algorithms with control over illumination, geometry and cameras. Non-curve-based multiview stereo and SfM algorithms also benefit from this dataset, as we provide full detailed mesh ground truth.

The dataset consists of:

Vase Dataset

Real data obtained from manually marking edges on structured light scans.

Overview

This real curve 3D groundtruth is constructed by manually deleting points of a dense point cloud obtained from structured lighting. Using the point cloud alone, the 3D edges are not identifiable with confidence. Therefore, we reproject the dense point cloud scan onto reference images during editing for disam biguating edges. The unstructured point cloud from structured lighting tends to suffer from oversmoothing, and lacks structure near edges, which we recover from the reference images registered using the ground truth camera parameters.

Red points near edges obtained from structured lighting registered to images

Points from the 3D scan that are on homogeneous regions are manually deleted. The selected points to be deleted are shown in yellow simultaneously in reference views and on the 3D scan itself, so that with confidence we know its not an edge
