Yes.. My main question though is if the misalignment within the 2 PCs should be uniform. Otherwise if the signal is not uniform then no matter how close the points are or how high my density is, the ICP or any other registration algorithm will fail in extracting a uniform tranformation matrix, right?

I chose the points that are not further than 1m from each other, and I rerun the ICP.
It minimizes the error, but there is till a shift of 30 cm.

Hi Daniel,

Thanks a lot for your reply.

My main question is basically if the 2 datasets need to have a uniform misaligment through the whole point cloud,
for helping the ICP to find a global rotation and trnslation matrix.
Unofrtunately as you see, this is not the case in my tree tops points..

Hello, I have a question of general interest, and not that much cloud compare related. But since I am using the ICP implementation on CC, I am asking for an advice here: So, I have 2 datasets of 2 different Lidar flights over a forest. I have exctracted the points that correspond to the tree tops, a...

Hello,

Thanks a lot! Both options are very useful to me in any case!


Have a nice day,

Hello, I have made an intersection on a point cloud, then a picked a point and saved its label by pressing ''save current label-added to cloud children). The point appears on the panel below the intersection, but when I am trying to save/export the point I get an error '' Dependency broken: entity '...

Yes. Here it is what the CC command line shows me:


And the RESULT.las file is nowhere..

Hi, Thanks for your info. I am running it as following, and everything works fine except for giving to the new file the name I want ''RESULTS''. I have placed this command in different positions but never works: C2M=subprocess.Popen(["C:\Program Files\CloudCompare\CloudCompare.exe","-...

Hi, Thanks for your reply! It seems that it doesn't work. And the "AUTO SAVE OFF" option does not make any difference in the output. All the following options give the same results: C2M=subprocess.Popen(["C:\Program Files\CloudCompare\CloudCompare.exe","-O",input_PC,&qu...

Good afternoon, I am trying to run c2m distance algorithm using python, with the following command: C2M=subprocess.Popen(["C:\Program Files\CloudCompare\CloudCompare.exe","-O",input_PC,"-O",input_Mesh,"-c2m_dist","-AUTO_SAVE","OFF","-S...
