Re: Cut the point cloud with a plane

Thanks Daniel you were very helpful! I wanted to ask you another question. When I create a plane, it doesn't keep the global coordinates. how can i do to create a plane that has global coordinates? I need to have the geo-referenced plan.

Cut the point cloud with a plane

Hi everyone, congratulations to the community. Is there any way to cut a point cloud according to a plane? Is it possible to do this on cloudcompare? If not, are there any other software that allows me to do this? I know I can do this by drawing a polyline, change the view and use the "segment&...

Re: Close a tunnel mesh

Thanks again for your response DA523. I was able to calculate the mesh with other software. Unfortunately cloudcompare is a mess. With other software I can generate a discrete mesh on the whole file, not the sectioned one on the area of interest. This means that I have to cut the area of interest on...

Re: Close a tunnel mesh

Thanks DA523 for your reply! I don't know if this method can work well due to the very complex geometry. You also told me that this approach does not work if you have more than 2 points with the same Z (i.e. more than 2 ceilings). Is there no way to calculate the tunnel mesh and then find the volume...

Close a tunnel mesh

Goodmorning everyone! I need to close a tunnel mesh but haven't found a way. I'll explain well what my input data are and what I would like to get. I have a point cloud from a cave obtained from a laser scanner. My goal is to select only one section of the cave and on this to calculate the internal ...

Re: Align laser scanner cloud on georeferenced cloud. Global shift problems

Maybe I'm wrong but I noticed that if I perform the ICP alignment with different global shift, when I close everything and reopen the files are not in the same position. I noticed that to be in the same position they must have the same global displacement at the time of alignment and if I force the ...

Align laser scanner cloud on georeferenced cloud. Global shift problems

Hello everyone, I'm new here. I ask you for help hoping to solve a problem that I have in cloudcompare for a few days. I have two terrestrial laser scanner files from the same area but captured at different times. One of the files is geotagged correctly and one is not. My goal is to be able to super...
