在这段代码中,setCorrespondences()函数的调用是错误的,因为pcl::IterativeClosestPoint<PointT, PointT>类中没有定义该函数。正确的做法是将pcl::CorrespondencesPtr类型的指针correspondences_filtered作为参数传递给pcl::IterativeClosestPoint<PointT, PointT>类的align()函数,从而进行点云配准。修改后的代码如下:
```
pcl::IterativeClosestPoint<PointT, PointT> icp;
icp.setInputSource(source_cloud);
icp.setInputTarget(target_cloud);
icp.setMaxCorrespondenceDistance(0.05);
pcl::registration::CorrespondenceRejectorSampleConsensus<PointT>::Ptr ransac(new pcl::registration::CorrespondenceRejectorSampleConsensus<PointT>());
ransac->setInputSource(source_cloud);
ransac->setInputTarget(target_cloud);
ransac->setInlierThreshold(0.05);
ransac->setMaximumIterations(1000);
ransac->setInputCorrespondences(correspondences);
pcl::CorrespondencesPtr correspondences_filtered(new pcl::Correspondences);
ransac->getCorrespondences(*correspondences_filtered);
PointCloudT::Ptr aligned_cloud(new PointCloudT);
icp.setInputCorrespondences(correspondences_filtered);
icp.align(*aligned_cloud);
```
注意,这里通过icp.setInputCorrespondences()函数将点对应关系传递给ICP算法,从而进行点云配准。
