Implication

Automated virtual reassembly demonstrates low cumulative error in fragmented cultural relics, suggesting a robust solution for digital restoration.

Key Points

To develop an automated framework for the virtual reassembly of fragmented cultural relics using multi-feature extraction techniques.
Extracted contour points from fragment point clouds using neighborhood roughness analysis.
Used a Cylinder Box-based completion strategy to recover missing contour segments.
Constructed multiple complementary features like FPFHs, HKSs, and a spatial cube-based contour shape descriptor.
Employed a tree-based fragment retrieval strategy alongside a coarse-to-fine registration scheme.
Introduced a pseudo-ground-truth accuracy evaluation method to assess reassembly performance.
Achieved a cumulative error as low as 1.58% in reassembly results.
Demonstrated stable and visually consistent results with the proposed method.
Significantly reduced computational complexity compared to exhaustive matching strategies.
