Recovery of Feature Edges in 3D Object Scans
In this challenge, the very recently introduced CC3D dataset  is considered. The CC3D dataset contains 50k+ pairs of CAD models and their corresponding 3D scans. The CAD models were converted to 3D scans using a proprietary virtual 3D scanning pipeline developed by Artec3D. Unlike ShapeNet and ModelNet, the CC3D dataset is a collection of 3D objects unrestricted to any category, with the complexity varying from very basic to highly detailed models. The availability of CAD-3D scan pairings, the high resolution of scans, and the variability of the models make the CC3D dataset unique.
The participants to this challenge will be given training and validation sets of 3D scans annotated with sharp edges obtained from the CAD models. For evaluation, only the 3D scans will be provided, and the task is to recover the sharp edges that approximate well the ground-truth annotations.
