中文简介:
提出了一种局部重叠三维曲面的快速全局配准算法。该算法对覆盖表面的候选匹配进行操作。单个目标被优化以对齐表面并禁用虚假匹配。目标被密集地定义在表面上,优化实现了没有初始化的紧密对齐。在内部循环中不执行任何通信更新或最近点查询。该算法的扩展可以实现多个部分重叠曲面的联合全局配准。大量的实验表明,所提出的方法匹配或超过最先进的全球注册管道的准确性,同时至少快一个数量级。值得注意的是,所提出的方法也比局部细化算法(如ICP)更快。它提供了良好初始化的局部细化算法所达到的精度,而不需要初始化和较低的计算成本。
课程简介: We present an algorithm for fast global registration of partially overlapping 3D surfaces. The algorithm operates on candidate matches that cover the surfaces. A single objective is optimized to align the surfaces and disable false matches. The objective is defined densely over the surfaces and the optimization achieves tight alignment with no initialization. No correspondence updates or closest-point queries are performed in the inner loop. An extension of the algorithm can perform joint global registration of many partially overlapping surfaces. Extensive experiments demonstrate that the presented approach matches or exceeds the accuracy of state-of-the-art global registration pipelines, while being at least an order of magnitude faster. Remarkably, the presented approach is also faster than local refinement algorithms such as ICP. It provides the accuracy achieved by well-initialized local refinement algorithms, without requiring an initialization and at lower computational cost.
