How to resize an existing point cloud file?

I am trying to enlarge a point cloud data set. Suppose I have a point cloud data set consisting of 100 points & I want to enlarge it to say 5 times. Actually I am studying some specific structure which is very small, so I want to zoom in & do some computations. I want something like imresize() in Matlab. Is there any function to do this? What does resize() function do in PCL? Any idea about how can I do it?

Solution

  • Since you want to increase the number of points while preserving shape/structure of the cloud, I think you want to do something like 'upsampling'.

    Here is another SO question on this.

    The PCL offers a class for bilateral upsampling.

    And as always google gives you a lot of hints on this topic.
