| 摘 要： | 利用无人机影像生成点云数据时，会产生一些噪声点，这些噪声点对点云数据的分类提取等会带来不利影响。为了消除这些噪声点，利用栅格法去除浮在点云上方的稀疏点，并利用pcl库的StatisticalOutlierRemoval滤波器去除离群噪声点，以及利用双边滤波算法对小型的噪声点进行纠正。试验结果表明，本文方法既保留了目标地物的几何特征，又能够有效地去除影响目标地物识别的噪声。

| Abstract: | In this paper, we extracted point cloud data from image of UAV with overlapping regions. There are some noise points while extracting the data. These noise points will have a great impact on the image classification and other operations. Therefore, we need to remove the noise points. A grid method is used to remove the sparse points above the point cloud. StatisticalOutlierRemoval filter of PCL Library is used to remove outliers noise. A bilateral filter is used to deal with small noise. Through experiments, we can not only retain the characteristics, but also remove the noise points. |
