Synthetic Dataset of InfraDiff

To address the lack of large-scale point clouds dataset for training point cloud completion models in civil engineering, we publish this dataset. This dataset comprises 1,000 synthetic single-span masonry arch bridge point cloud samples for point cloud completion. Each single-span sample includes 1 ground truth point cloud and 24 partial point clouds with varying perspectives and degrees of data loss, a total of 24,000 sample pairs for training. For ease of processing, each sample is stored as a binary (.pt) file.
