I am wondering if there is any way to create a model that can be used in a RANSAC scheme where a spline or polyline could be determined from a noisy 3D point cloud.
What I have is a volume containing a set of points in each XY-plane, having say 400 of these in the Z-direction and a spline shape emerges visually while simply looking at the plotted data in 3D space. I already have a line fitting RANSAC scheme where the error is determined by a simple distance measure but I can't get my head around how to determine a model for a spline/polyline.
