VGGT-CD: Training-Free Robust Registration for 3D Change Detection

In three linesVGGT-CD is a training-free pipeline for 3D change detection from multi-view images. It decouples cross-temporal registration from dynamic-change interference via joint keyframe inference and dense reconstruction purification. On the World Across Time benchmark, it reduces Absolute Trajectory Error by 44% outdoors and 59% indoors, 6× faster.
