PCL registration

[JoyMazumder]

Hello, I want to run this code. here cloud_output variable shows that there are some pixels. But while trying to visualize that it gives no output.

Hi. We will need you to provide the files you're passing as arguments to the app, otherwise it'll be difficult to reproduce your problem.

The detected location is not accurate. I am using PCL-1.8.1, VS-2015. PPF estimator provides some neg value on f1, f2...etc.
I have added the PPFRegistration output here

I have used normal_estimation_filter.setKSearch(5); line instead of normal_estimation_filter.setRadiusSearch (normal_estimation_search_radius);

I tried after changing several parameters but the same result

Most of the case shows #pose votes 1. If I increase threshold parameters then it changes but bad result as before.

Hi Joy,
Did you get your result correctly for PCL registration ?

Hi Joy,
Did you get your result correctly for PCL registration?

Hello, There is a problem in PPF Estimation function in PCL. ( #1131 ) . So, I used PPF OpenCV implementation

Hello Joy,
I am new to computer Vision field. I am working a small project where I am stuck with registration of multiple point clouds. I am using reference from below link for registration algorithm.
https://github.com/tttamaki/ICP-test/blob/master/src/icp4_after_feature_registration.cpp
However, my registered output doesn't seem to be correct. When i concatenate registered frames, they don't seem to be overlapped properly.
Can you suggest any idea where i should look into?

Thanks for you help in advance.
