Hey guys,

Do you know any pcl example or source code that does decompose objects into their components by using any kind of a method?

I know that there are SAC based segmentation methods that does primitive shape fitting but I don't think they are able to extract mug handles or other similar sub-components. Well you can get the handle after extracting the cylinder-like mug component, but I need sth that is able cluster other smaller parts also.

I need this just for visualization purposes, it is not required to run online/real time, it is adequate to be able to work on stationary scenes/inputs.

Thanks

I am not an expert in 3D segmentation, so if somebody is then please correct me if I am wrong, but I believe that the problem of segmenting an object point cloud into different parts is still an open research question. I don't think there is anything built in to PCL which can perform this.

Some people are working on this problem (using radial reflection or bounding volume hierarchies for example), but I don't see any released code.
