A question about how to create the dataset。 #11

Thank you very much for your last reply. But right now I have a question about the dataset. Is the 3DMatch dataset the 20 anchor points selected after 50 depth.png is fused into a.ply file? I see that there are 705940 patches in your 3DMtach dataset(are there 705940 anchor,right?), but there are only 5146 .ply files combined from 3DMatch dataset. May I ask how to select your 705,940 patches? In other words, how are the 705,940 points selected, because if a .ply file selects 20 anchor points, there are only 102920 points. Looking forward to your reply. Thank you.
