Parameters of topological coding technology for defect area detection.
| Parameter name | Technical description | Range / dimension | Notes |
|---|---|---|---|
| Number of mesh vertices | Count of vertices in the 3D mesh structure | 8000–45,000 | Defining geometric resolution |
| Normal vector dimension | Spatial components of local surface normals | 3 | Corresponding to X/Y/Z axes |
| Node feature dimension | Length of embedded feature vector per node | 64/128/256 | Adjusted according to network depth |
| Normalization coefficient range | Weight range for neighboring node aggregation | 0.15–0.95 | Regulating proportion of feature flow |
