标靶是地面三维激光扫描技术中必不可少的附件之一，标靶的准确定位对于地面Lidar点云数据处理至关重要。提出基于模糊聚类的稳健平面标靶定位算法，对标靶的分类数、初始聚类中心等问题进行了讨论，并通过稳健平面拟合算法去除点云数据中的异常点，从而获取平面标靶的坐标。实验证明了该算法的有效性与正确性。
標靶是地麵三維激光掃描技術中必不可少的附件之一，標靶的準確定位對于地麵Lidar點雲數據處理至關重要。提齣基于模糊聚類的穩健平麵標靶定位算法，對標靶的分類數、初始聚類中心等問題進行瞭討論，併通過穩健平麵擬閤算法去除點雲數據中的異常點，從而穫取平麵標靶的坐標。實驗證明瞭該算法的有效性與正確性。

Targets are one of the necessary accessories in terrestrial Lidar, and determination of their location is important for point clouds data processing. A new method for location determination of targets is proposed based on fuzzy clustering. Some important problems such as the number of cluster, initial cluster center were discussed. Robust planar fitting method was used to eliminate outliers of point clouds, and targets coordinates were obtained. Experiments were carried out and the results showed correctness and effectiveness of the method.
