Enhanced Geometric Representation
Traditional local point cloud descriptors often fall short due to single-scale analysis and lack of topological correlations, which limits their effectiveness on complex fracture morphologies. Our method introduces a refinement algorithm based on local normal vector statistics and regional connectivity graph convolution. By constructing multi-scale geometric descriptors combined with regional topological constraints, a dynamic representation model for fracture surface geometry is established. This significantly enhances feature discriminability, crucial for accurate alignment.
Texture Information Integration
Existing Iterative Closest Point (ICP) algorithms primarily rely on geometric distance metrics, often overlooking the semantic continuity of surface textures, which can lead to misaligned texture directions after registration. To overcome this, we designed a novel texture gradient direction consistency verification rule. Leveraging the spatial continuity of RGB-D data, the texture gradient field of the fracture surface is extracted and its directional continuity is embedded as a hard constraint in the ICP error function. This ensures both geometric alignment and critical texture continuity, particularly for Jiandu's distinct ink strokes and bamboo fiber textures.
Noise Suppression Optimization
Traditional Gaussian kernel functions are highly sensitive to heavy-tailed noise, leading to nonlinear divergence in registration errors. To mitigate this, our method constructs an adaptive weight adjustment mechanism based on the Generalized T-Student Kernel. Theoretical analysis rigorously proves that this method significantly enhances heavy-tailed noise suppression compared to traditional Gaussian kernels, resulting in a more robust and stable ICP-based optimization, particularly in the presence of real-world scanning noise and incomplete data.

Case Study: Jiandu Reassembly - Preserving Ancient Chinese Heritage
Jiandu artifacts, ancient Chinese writing materials, are crucial carriers of civilization but present significant challenges for high-precision digital restoration due to their fragmented nature, complex fracture surfaces, and susceptibility to noise. Traditional manual reassembly is time-consuming and risks secondary damage to fragile materials. Our proposed method provides a non-contact, high-precision solution, directly addressing the unique material properties and structural characteristics of Jiandu manuscripts. By leveraging multi-modal data fusion and robust optimization, it enables the accurate reassembly of these invaluable historical records, safeguarding them for future generations while preserving their critical textual and material integrity.
