Improved 3D Gaussian splatting integrating VGGT and LiDAR: Application in visual relocalization for UAV inspection of large aircraft

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...

Research on binocular 3D measurement method for notch damage in aero-engine blades based on geometry-aware keypoint localization

Accurate quantification of notch damage from in-service aero-engine blade borescope images is vital for maintenance decision-making. Traditional manual point-selection and heatmap-regression-based keypoint localization methods often fail to deliver stable industrial-level measurement accuracy under complex imaging cond...
