PCL:实现改进快速欧式聚类
以下是使用Python和PCL库实现改进的快速欧式聚类(Improved Fast Euclidean Clustering)的完整源码:
python
import pcl
def improved_fast_euclidean_clustering(point_cloud, cluster_tolerance, min_cluster_size, max_cluster_size):
cloud = pcl.PointCloud()
pcl.save(point_cloud, "input_cloud.pcd")
pcl.load("input_cloud.pcd", cloud)
tree = cloud.make_kdtree()
# 改进的快速欧式聚类算法
ec = cloud.make_EuclideanClusterExtraction()
ec.set_ClusterTolerance(cluster_tolerance)
ec.set_MinClusterSize(min_cluster_size)
ec.set_MaxClusterSize(max_cluster_size)
ec.set_SearchMethod(tree)
cluster_indices = ec.Extract()
# 创建一个新的点云对象来存储聚类结果
clustered_cloud = pcl.PointCloud()
for j, indices in enumerate(cluster_indices):
for i, index in enumerate(indices):
clustered_c
