, the first training-free, VFM-empowered 3DUS stitching framework that integrates point-cloud (PCD)-based geometric features with DINOv3-derived semantic descriptors. Extensive experiments demonstrate that VFMStitch substantially improves rigid registration accuracy compared to existing methods, validating the effectiveness of geometric-semantic fusion for challenging 3DUS stitching scenarios. The code is available at github.com/MedICL-VU/VFMStitch.
