Parameters

Name Type Range Default Description
inPointsFil.Point3DGridData points to be aligned, may contain background clutter.
inReferencePointsFil.Point3DGridReference points to align to, may contain background clutter.
inSampleCountint<1, INF>500Number of random samples used by the registration algorithm. Recommended values are from 200 to several thousands. Default value: 500.
inOverlapfloat<0.0f, 1.0f>0.8fDefines the estimated overlap between two input grids (0 = no overlap, 1.0 = every point in inPoints is also in inReferencePoints). Default value: 0.8f.
inDeltaCorrectionfloat<0.0f, INF>9.3fDefines the accuracy of the final alignment. With smaller delta the amount of allocated memory increases. Default value: 9.3f.
inTransformLimits3DFtl.Optional<Fil.TransformLimits3D>Limits the maximum rotation angles and translation along each axis, of the final transform. Default value: ftl::NIL.
inMaxTranslationDistanceFtl.Optional<float><0.0f, INF>Limits the length of the translation vector of the final transform. Default value: ftl::NIL.
inSeedFtl.Optional<int>Seed for a random generator used by the algorithm. Default value: ftl::NIL.
outAlignedPointsFil.Point3DGridThe aligned input points.
outAlignmentFil.MatrixThe transform that aligns best the input points to the reference points.
outDeltafloatReturns estimated value of the parameter delta.
