Microwave imaging is promising for non-contact inspection of radar-absorbing materials (RAMs); however, strong structured non-damage responses in reconstructed microwave images can resemble surface defects and trigger false detections, while hard masking may remove weak damage responses near ambiguous boundaries. To ad...

For high-precision unmanned aerial vehicle (UAV) visual relocalization in large-scale aircraft inspection, this paper proposes an improved 3DGS method integrating visual geometry grounded transformer (VGGT) with LiDAR and designs a coarse-to-fine two-stage image matching strategy to tackle the challenge. First, the low...
