[SOLVED] pcl_ros: how to find cloud frame
Dear all, I am using pcl_ros package, with pcl 1.6 and ROS groovy. I am subscribing to a PointCloud2 topic, using a callback like this:
void MainWindow::xtionCloudCallback(const pcl::PointCloud<pcl::pointxyzrgb>::ConstPtr& cloud)
is it possible to get the cloud frame? if I transform the cloud using a TransformListener tf, e.g.:
pcl_ros::transformPointCloud("/map", *cloud, *tcloud, tf);
this function is able to retrieve the cloud frame in some way, how do I get it?
