摘要:

提出了一种新的三维散乱点云多尺度算子。法线差(DoN)提供了一种计算效率高的多尺度方法来处理大型无组织的3D点云。定量和定性地展示了DoN在两个不同的真实世界室外城市LIDAR场景数据集的多尺度滤波中的应用。在这两个数据集中,DoN算子被证明可以将大型3D点云分割成规模突出的集群,例如汽车,人和灯柱,用于半自动注释中的应用,并作为自动对象识别中的预处理步骤。该算子在一个大型的户外LIDAR场景公共数据集上进行了评估,并给出了地面实况注释。

英文摘要:

A novel multi-scale operator for unorganized 3D point clouds is introduced. The Difference of Normals (DoN) provides a computationally efficient, multi-scale approach to processing large unorganized 3D point clouds. The application of DoN in the multi-scale filtering of two different real-world outdoor urban LIDAR scene datasets is quantitatively and qualitatively demonstrated. In both datasets the DoN operator is shown to segment large 3D point clouds into scale-salient clusters, such as cars, people, and lamp posts towards applications in semi-automatic annotation, and as a pre-processing step in automatic object recognition. The application of the operator to segmentation is evaluated on a large public dataset of outdoor LIDAR scenes with ground truth annotations.
