Bin Picking: Flange 4 Holes
SUMMARY
Physics-simulated, photorealistic RGB renders of metallic 4-hole flanges in industrial KLT/Euronorm bins, generated with Extreme Domain Randomization (EDR) for sim-to-real transfer, with pixel-accurate instance masks. Access this dataset on Kaggle: Bin Picking Flange 4 Holes

About the Dataset
A synthetic dataset for instance segmentation of 4-hole mechanical flanges in cluttered industrial bins, targeting applications in bin-picking, sim-to-real transfer, and amodal/occlusion-heavy segmentation.
Each scene is constructed by spawning 20–30 flange instances above a randomly selected industrial container and running a rigid-body physics simulation to settle them into a natural, self-occluding pile. The settled scene is then rendered from 4 randomized camera poses under Extreme Domain Randomization (EDR) — aggressive variation of lighting, materials, and backgrounds — yielding photorealistic RGB images with per-instance segmentation masks that transfer well from simulation to real-world inference.
