"Webb25 jan. 2024 · It's working fine on the point cloud you sent, on your code, as well as on the code given in the tutorial. As the point cloud contains only planes, it takes more iterations to fit, as the change in rmse / fitness, in that case, is very less between iterations. That's why in many applications, planes are removed before using ICP operation. " - Initial transformation
