I an using ICP (Iterative Closest Point algorithm - vtkIterativeClosestPointTransform) and so far works great for stl data that I have.
But I just received some new stl files and it doesn’t give correct results, even the surface looks very good.
Do you think that bad triangulation would cause these wrong results? I tried to re-generate my stl with better triangulation, but still, ICP is not working as expected.
Do you have any idea that can help me investigate further?
Hi @siaeleni - probably it also depends a lot on initialization - are the new datasets close before you run the ICP? Maybe you can share examples of data that do and don’t register well?
I haven’t used ICP a lot myself, but I plan to soon so I’d also be interested in hearing any advice about what works well.
Exactly, you are right. My data are generated from different people with different software,
thus these after the initial guess (after the translation) are not very close.
Probably a pre-process step is needed here.
