Question about the 3D annotation generation pipeline #34

Hi! Thank you for the great work.

I have a question regarding step b of the below pipeline :

What is the exact meaning of the sentence "The position of points on the 2D annotation are interpolated to get a dense point set". Is the interpolation done in 3D (using the matched 3D points of step a) or is it done in the 2D plan (somehow using the remaining 2D points that were not matched with any projected 3D points in step a)?

Thanks for your clarification !

Hi,we finish interpolation process in 3D
