Scan-CAD Object Similarity Dataset

We present the Scan-CAD Object Similarity dataset consisting of 5102 ranked scan-CAD similarity annotations.To construct this dataset we use ScanNet, Scan2CAD and ShapeNetCore.v2. We extract the regions of scanned objects from ScanNet scenes using its semantic segmentations and bring the object into a canonical pose using the correspondences from Scan2CAD.To build a ranked list of similar CAD models, we developed an annotation interface where the annotator sees 6 proposed CAD models, which are similar to a specific scan query, selects up to 3 most similar CAD models from this pool and ranks them.If you would like to get access to the Scan-CAD Object Similarity dataset, please fill out this google form, and once accepted, we will send out the download link.
