match_chamfer_3d — 3D match_localize op

• Data kinds: voxel × voxel → position

• Call: import match3d; match3d.match_chamfer_3d(scene, template, device='cpu', thr=0.3, edt='scipy') (or ops3d.get("match_chamfer_3d"))

• GPU: this op has a GPU path (device="cuda")

Usage

Chamfer / distance-field matching (robust to partial views and occlusion). The voxel × chamfer column.
