Abstract:

•The paper focuses on 3D reconstruction for large-scale scenes.•We design hierarchical signed distance field (H-SDF) for multi-scale depth map fusion.•An improved marching tetrahedra algorithm based on H-SDF adjustment is proposed.•To improve efficiency, we use a two-phase search strategy on feature matching.•The coarse search with the BO...More
