Abstract—Point cloud registration is a central problem in many computer vision problems. However, ensuring global consistency of the results of pairwise registration of point clouds is still a challenge when there are multiple clouds because different scans should be converted to a common coordinate system. This paper describes a global refinement algorithm that first estimates rotations and then estimates parallel translations. For global refinement of rotations, a closed-form algorithm based on matrices is used. For global refinement of parallel translations, a closed-form algorithm is also used. The proposed algorithm is compared with other global refinement algorithms.

根据点云序列重建三维场景的全局细化算法

摘要--点云注册是许多计算机视觉问题的核心问题。然而，当存在多个点云时，要确保点云配对注册结果的全局一致性仍是一个挑战，因为不同的扫描应转换到一个共同的坐标系。本文介绍了一种全局细化算法，该算法首先估算旋转，然后估算平行平移。对于旋转的全局细化，采用了基于矩阵的闭式算法。对于平行平移的全局细化，也采用了闭式算法。将所提出的算法与其他全局细化算法进行了比较。
