Interpolating a 3D Point Cloud at a Defined Interval

I am trying to compare two 3D point clouds to each other, which requires interpolation in each dataset to compare exact coordinates. Is there a simple way in MATLAB to do this? I was hoping to have a defined XYZ grid of 1 cm intervals.

Maybe griddata?

I was hoping to have a defined X/Y grid of 1 cm intervals.

If it's a 3D point cloud, don't you mean an X/Y/Z grid?

[Casey O'Heran]

Yes, you're right.

Hi,

Functions like delaunayTriangulation and scatteredInterpolant can be used to interpolate the data and get a Denser point cloud. For smoothening, use Savitzky-Golay filter.

Hope this helps!
