基于平面层结构勘察的点云快速分割

针对具有空间连通域特征的点云,提出了一种新颖的基于平面层结构勘察的快速分割方法。首先建立点云的平面层结构,并进行最优勘察,同时进行平面层连通性的判断,最终确定最优平面层,并实现迭代分割。算法应用于实际项目中采集的点云的分割,并分别对不同规模的点云的分割结果进行了讨论。结果表明,算法对具有空间连通域特征的点云能有效并较快地进行分割。

Fast Segmentation of Point-cloud Based on Plane-storey Structure Exploration

An novel and fast segmentation method based on the exploration of plane-storey structure is proposed for point-cloud featured with spatial connective region.The plane-storey structure is first established and the optimum exploration is achieved by the judgment of connectivities,and finally the optimum plane-story is determined and the iterative segmentation is achieved.The method is applied to the point-could acquired from a concrete project and the results of segmentation of point-clouds with different scale is discussed,showing that the me thod is effective and fast with respect to the point-cloud with spatial connective region feature.
