[ros-users] Registration issues with PCL

I am facing some issues with registration in PCL. I created a ROS node which
simply subscribes to "/shoulder_cloud" topic and obtains pointcloud. It is
then supposed to register the received point clouds and publish them. The
package and the bag file (for the point clouds) can be found at the
Bag : http://ias.cs.tum.edu/~indorewala/exploration.bag
I basically first set the input model and input cloud as follows:
icp.setInputModel( pointcloud );
icp.setInputCloud( pointcloud );
And then run the compute function as follows:
icp.compute( output );
and publish the output.
The problems I am facing are as follows:
1. The ICP algorithm does not converge. I have to manually set the maximum
number of iterations in order to exit the algorithm.
2. Even after setting the maximum number of iterations, the transformed
cloud does not look good.
3. When I try to run the getFitnessScore() function, my package crashes.
If you have faced a similar problem or have an idea of what might be the
reason, I would be glad to see your reply.
Thanks in advance.
