Best fit of point cloud to another point cloud in python

Question

I have the following problem:

From a txt-file I have two arrays with x,y,z coordinates of each point cloud and a temperature value. I extracted the coordinate lists out of two fem-files. Both describe a similar part but the distance from point to point are different in each point cloud.

Now I want to match the first point cloud to the other. At the end I want to map the temperature value of the first point cloud to the second point cloud.

Array_1 [point_index, x-coordinate, y-coordinate, z-coordinate, temp. value]
Array_2 [point_index, x-coordinate, y-coordinate, z-coordinate]

Goal: Array_2 with the temp value of the nearest point of Array_1 after fitting the point clouds on each other.

Sample Picture

Thank you for inspiration.

I didn't quite understand what is your goal, but point cloud registration sounds like what you are looking for. See if this fits your goal - http://www.open3d.org/docs/0.7.0/tutorial/Basic/icp_registration.html
