Three Cars Approaching within 100m! Enhancing Distant Geometry by Tri-Axis Voxel Scanning for Camera-based Semantic Scene Completion

Figure 1. In camera-based SSC, the projected distant geometry is sparse and unrealistic due to factors such as perspective and occlusion. Our ScanSSC addresses this challenge by referencing distant geometry to the context of more accurate near-viewpoint geometry. As a result, ScanSSC achieves more accurate reconstructions of both distant and near scenes, outperforming existing camera-based SSC methods such as VoxFormer-T [14] and CGFormer [38].
