Inversion results of sheet-like model. The models are divided into three groups. The first group represents the ground truth of the 3D model, displayed using both point cloud and facet representations. The second group shows the 3D model reconstructed using our method, where the point cloud is converted into triangular facets for easier comparison with the KTM method. The third group represents the 3D model reconstructed using the KTM method. All models are aligned with the asteroid-centric coordinate system for consistency and clarity in comparison.
