Marble Offcut Dataset: 150 Segmented Offcuts with Thickness and Shape Metrics
Listed in ETH Zürich Research Collection
Binary footprint masks, measured thicknesses and shape metrics for 150 individual physical marble offcuts.
Description
Offcuts were photographed on a robot pick platform, located with ArUco fiducials for metric scale, and segmented with point-prompted SAM2. Each offcut carries its footprint mask at platform level (parallax-corrected, rotated so its longest hull edge is axis-aligned, cropped tight), its thickness from a robot-mounted ultrasonic probe, a pixel-to-millimetre scaling factor, and five shape descriptors: area in pixels and square millimetres, eccentricity, solidity, aspect ratio and circularity.
The dataset is the offcut inventory used by the packing method described in the related publication.
