摘要:

配准是点云处理中的一项基本而关键的任务,它通常依赖于从两个点云中找到元素对应。然而,找到可靠的对应关系依赖于建立一个强大的和有区别的描述元素和正确匹配的相应元素。在这封信中,我们开发了一种由粗到细的配准策略,该策略利用旋转不变特征和一种新的加权图匹配方法来迭代查找对应关系。在图匹配方法中,利用欧氏空间和特征空间中节点和边的相似度来构造优化函数。所提出的策略进行评估,使用两个基准数据集,并与几个国家的最先进的方法进行比较。关于实验结果,我们提出的方法可以实现一个精细的注册与旋转误差小于0.2度和平移误差小于0.1米。

英文摘要:

Registration is a fundamental but critical task in point cloud processing, which usually depends on finding element correspondence from two point clouds. However, the finding of reliable correspondence relies on establishing a robust and discriminative description of elements and the correct matching of corresponding elements. In this letter, we develop a coarse-to-fine registration strategy, which utilizes rotation-invariant features and a new weighted graph matching method for iteratively finding correspondence. In the graph matching method, the similarity of nodes and edges in Euclidean and feature space are formulated to construct the optimization function. The proposed strategy is evaluated using two benchmark datasets and compared with several state-of-the-art methods. Regarding the experimental results, our proposed method can achieve a fine registration with rotation errors of less than 0.2 degrees and translation errors of less than 0.1m.
