Write PCD File from a Topic - Hydro + PCL (Migration)

edit

Hello, I'm doing a hand gesture recognition project and I am having some troubles with the migration of the PCL data types to ROS Hydro. I started with Hydro + PCL this week so, not all the concepts are really clear for me. I'm using Ubuntu 12.04.

My problem is to transform the data that come from my passthrough filter (sensor_msgs/PointCloud2) to a pcl::PointCloud pcl::PointXYZRGB, so I can write the data using the savePCDFileASCII function.

My code is:

#include <ros/ros.h>
#include <pcl_conversions/pcl_conversions.h> //hydro
#include <sensor_msgs/PointCloud2.h> //hydro
#include <pcl/point_cloud.h>
#include <pcl/point_types.h>
#include <pcl/io/pcd_io.h>

ros::Publisher pub;

void
cloud_cb (const pcl::PCLPointCloud2ConstPtr& input)
{

  pcl::PointCloud<pcl::PointXYZRGB> cloud_filtered;
  pcl::fromROSMsg(*input, cloud_filtered);

  //cloud_filtered.header = pcl_conversions::toPCL(input.header); 

  //pcl_conversions::toPCL(input, cloud_filtered);

  pcl::io::savePCDFileASCII ("test_pcd.pcd", cloud_filtered);

  pub.publish(input);
}

int
main (int argc, char** argv)
{
  // Initialize ROS
  ros::init (argc, argv, "pcl_node");
  ros::NodeHandle nh;

  // Create a ROS subscriber for the input point cloud
  ros::Subscriber sub = nh.subscribe ("/passthrough", 1, cloud_cb);

  // Create a ROS publisher for the output point cloud
  pub = nh.advertise<sensor_msgs::PointCloud2> ("output", 1);

  // Spin
  ros::spin ();

  //End Program
  return (0);
}

As you guys can see in my code, I tried some transformations after reading the hydro/Migration page, but I couldn't figure it out what i need to do to make my code work.

The error while doing catkin_make is a no matching function because the type error:

/home/breil/catkin_ws/src/pcl_tutorial/src/example.cpp: In function ‘void cloud_cb(const PCLPointCloud2ConstPtr&)’:
/home/breil/catkin_ws/src/pcl_tutorial/src/example.cpp:21:41: error: no matching function for call to ‘fromROSMsg(const pcl::PCLPointCloud2&, pcl::PointCloud<pcl::PointXYZRGB>&)’

/opt/ros/hydro/include/pcl_conversions/pcl_conversions.h:486:8: note: template<class T> void pcl::fromROSMsg(const PointCloud2&, pcl::PointCloud<PointT>&)

Thank you very much for your attention.
