The statistical evaluation of the proposed method and the ICP algorithm for datasets in Fig 4.

S13 Dataset is the detected CVPs by the ICP algorithm and S14 Dataset is the transformed S2 Dataset with S13 Dataset. S15 Dataset is manually detected corresponding point pairs between S10 Dataset and S1 Dataset for statistical evaluation.S13数据集为经ICP（Iterative Closest Point，迭代最近点）算法检测得到的CVP集合；S14数据集为利用S13数据集对S2数据集进行变换后得到的数据集；S15数据集为人工检测得到的S10数据集与S1数据集之间的对应点对，用于统计评估。
