| 中文简介: |  由于缺少纹理的物体或线状结构的存在，为人造环境生成准确的3D模型可能是一项艰巨的任务。由于传统的基于点的3D重建方法可能无法将这些结构集成到生成的点云中，因此需要不同的特征表示。我们提出了一种新颖的方法，该方法使用点特征进行相机估计，并使用其他线段进行3D重建。为了避免基于外观的线匹配，我们将纯几何约束用于假设的生成和验证。因此，所提出的方法能够重建线状结构以及实体。该算法旨在使用Motion和在线基于3D建模的在线结构并行生成增量结果。我们证明了该方法在运行时间方面要优于以前的描述符较少的行匹配方法，同时还能提供准确的结果。 |
| 课程简介: | Generating accurate 3D models for man-made environments can be a challenging task due to the presence of texture-less objects or wiry structures. Since traditional point-based 3D reconstruction approaches may fail to integrate these structures into the resulting point cloud, a different feature representation is necessary. We present a novel approach which uses point features for camera estimation and additional line segments for 3D reconstruction. To avoid appearance-based line matching, we use purely geometric constraints for hypothesis generation and verification. Therefore, the proposed method is able to reconstruct both wiry structures as well as solid objects. The algorithm is designed to generate incremental results using online Structure-from-Motion and linebased 3D modelling in parallel. We show that the proposed method outperforms previous descriptor-less line matching approaches in terms of run-time while delivering accurate results. |
