A different way if you want all the detail from the other pointcloud is to merge the 2 pointclouds, and subsample the spacing with a really low number. that eliminates one pointclouds points that are located at the same position as the other pointcloud. Hope it makes sense :)
Thanks Jonathan. I have a problem. After merging two images, I found that there is ghosting. It looks good in the point cloud, why is there ghosting after it comes out?
Great tutorial! What do you need to do if you have a point cloud (PC) from a laser scanner (LS) and a point cloud from photogrametry? (PG) The accuracy from the LS is +/-2mm, from the PG is +/-50mm. I do not want to scale the PC from the LC, that one is correct for me. How do I scale the PC from the PG?
When processing using photogrammetry, use control points that do not account for scale factor. In other words, add the difference between your ground/grid dataset into grid control points. Fool the photogrammetry a bit.
thank you for the tutorial, I have been using the app recently to scan hvac systems during construction, really useful. One question: I saw something about a beta program, does this have any cost or just anyone can try for free?
The best method we know to rescale a point cloud in CloudCompare is to take point to point measurements on several known objects and calculate the average error. Then, you can use Edit > Multiple/Scale to add a scale factor adjustment. For users developing solutions on the EveryPoint platform, we provide a toolset for adding targets in the scene and autoscaling the result during processing.
Can't figure out why my point clouds are not aligning. After very closely aligning the points through the equivalent point pairs button, I press the next button to "Finely Register" the clouds but the alignment goes wacky with the two clouds at different x, y and z angles. Don't know what I am doing wrong. Any advice?
That tutorial was exactly what I was looking for. Thanks so much.
Thank you for this! Having issues with another app with my scanner and this will help me complete a project
thanks for this video, very helpful
but I have a question
how can I scale objects, or match the size to the "reference" cloud
This was really helpful. Thanks!
Good Tut - thanks Jonathan.

This does make sense and works!
Very clearly presented.
Great tutorial, really helpfull.
Glad it was helpful!
Top lad, thank you very much
Can I merge two meshes from my 3d scan ? How available is this program
What camera did you use to capture this model?
thank you
Hello I am arriving late here, but is there a way after doinf the merge between models, unjoining them? thanks
Thanks Jonathan. I have a problem. After merging two images, I found that there is ghosting. It looks good in the point cloud, why is there ghosting after it comes out?
How to import it to Blender and set camera?
how can i make it to 3d model?
It's a dragging shadow
Nice!!
why when I have them close and I align 2 roughly aligned scans does it pull then apart

You can apply for the beta via our website: everypoint.io/beta
After aligning the files I am unable to select the 2 meshes to finer register the details why is it happening
Great tutorial Jonathan. Thank you. If a single scan is slightly out of scale, how do we rescale it in CC please?

for scalability reasons, any idea how to not rely on the initial manual registration (rotation/translation) of the point cloud ?
A bit of a late reply, however, ideally your point clouds have some level of GPS registration. Each scan may not be exact. ICP will fix that issue.

Do a majority of the two point clouds contain the same geometry or is there a small amount of overlap?
I HAVE TO DO IT manually?? Jesus
Since this has been posted, I don't think you have to roughly align the point clouds anymore. It's just a few clicks now.
Give it shot.
@thenerfguru Thank GOD 👁️👃👁️🙏
Thanks Dude 😎👍
