creating buffer for point cloud

[cherry1219]

Hi everyone,

i am working on a project to detect traffic signs which are occluded by vegetation. I have trained the classifier to classify traffic sign and vegetation, next step will be creating buffer zone e.g. 5 meters around the detected traffic sign to see if there is any vegetation grown around the sign. So I would like to know if cc provides way to create buffer for point clouds?

Thanks a lot:)

Well, CC can compute distance between 2 clouds for instance, so I guess it's a way to compute a 'buffer'? You can also generate a distance map/grid around a cloud. Maybe another way to do it?
