I've coded something, however the cubic, quadriatic and polynomial curve (red) don't follow the object's shape. It's supposed to fit similarly like the green line. Do you maybe have an idea how to approach this?

Thanks for the hint! Apparently RANSAC doesn't perform good for outlier removal in 3D point clouds.

Another thing, can a best fitting curve or B-spline (using least squared plane or RANSAC) be calculated in CC?

Hello, I’d like to use RANSAC for outlier removal in a point cloud. The idea is for each random subset of points to calculate the least squared plane and check the whole point cloud for outliers (within the given distance threshold or MAD). This would go iteratively until the max number of iteration...

I've turned the mesh into a point cloud and I used the Cloud-to-Cloud distance function. But I still don't know how to calculate the coverage (in percentage).

Hello.
I have a reference mesh that is 100% complete. On the other hand I've a point cloud (with gaps) who's completeness I should assess, regarding to the reference mesh. Is it possible to do that in 3D space and how?
Thank you.

Is it possible to adjust the M3C2 cylinder length in CC?

I've adjusted the overlap and it worked, thanks :). Now I've compared two different point clouds to the reference (TLS) using M3C2 and when I export the results for the Significant Change, the percentages ( Class start and Class end ) are always the same, just the Value varies. For example: Class Va...

I've tried a numerous combinations with different overlap percentage: from 5 up to 100%, different Random Sampling Limit, number of iterations and RMS and still the scans are not properly aligned. Also, since each scan has 360M points, I've subsampled the number of points, but no changes in the resu...

Hello, I have 12 TLS scans of a room in .e57 format. Each has around 360M points. The interior of room remains the same, only the scanner is moved. The goal is to align them all and complete a single scene. First I've used PointPickins for coarse registration (which is good) and then ICP (which make...
